Climate Change: can nature repair the planet? | The Economist


Today more people are demanding action… …to tackle the global climate crisis than ever beforeThis is a fight across borders, across continentsA sometimes bewildering array of critiques… …and responses are hitting the public consciousness We wanted to take a closer look… …at one of the most familiarTrees could remove nearly 25% of carbon dioxide from the atmosphereWe’re going to have to put trees everywhereThe target is to plant thousands of treesTrees suck up and store carbon……so why not plant more of them?It seems like a compellingly simple answer……to the question of how humanity can begin to repair the planetBut what do the experts think?I’m a film-maker here at The Economist……and I want to find out the real story behind trees and climate changeThe world’s ambition for reforestation……for planting trees has never been greaterPrivate companies have schemes……like even Pornhub, for exampleThey had a scheme where for every hundred views……they would plant a treeWow, really?Yeah, but because it’s just an easy win for companies to say……plant a tree, if you do this, we’ll plant a treeBut it’s not as simple as that……and it’s not necessarily……having the benefit that companies are sayingThis represents how much carbon could be stored……if all reforestation projects are plantations……and this is if you let all forests regenerate naturallyNatural, slow-growth forestYou can see it is drastically higherSo what are the pertinent……questions for you?So there’s a big study a few weeks ago……that said that tree planting has the mind-blowing potential……to tackle the climate crisis…So I think that’s the kind of key starting point……for our researchLooking at, to what extent that’s trueTo what extent trees and planting of trees can……tackle climate changeWhen this study from the Crowther Lab was published in July… …these were the headlinesA new study is suggesting that the best way to fight climate change……is through trees……study says it could reduce carbon dioxide in the atmosphere by 25%……nature sometimes has the best remedies right?So we’re about to call Professor Tom Crowther……who’s said that tree-planting has mind-blowing potential……to tackle climate crisis so we want to speak to him……find out how and see whether it doesn’t sound too good to be trueYeah so I’m Tom Crowther…….I’m an assistant professor of Ecosystem Ecology at ETH ZurichAnd we about a year ago here started the Crowther Lab……where we sort of bring together a lot of perspectives to have a……holistic understanding of where all the carbon on Earth is……and how we can manage ecosystems to store……more or less carbon in those areasFor your recent study, why is that new and important?So simply put we just made a very high-resolution model……of where trees could exist on the planetAnd by quantifying how much carbon is in that land……we can actually show that restoring forests can capture……far more carbon than we ever previously thought……what we’ve found is actually forests have the potential to capture……200 gigatonnes of carbon……and since the start of the Industrial Revolution we’ve got about……300 gigatonnes in the atmosphereSo it would be very slow, it would be over 200 years……but still we’re talking about a really, really powerful……carbon-drawdown solutionThese numbers sound greatBut how does that translate to real world, real lifeI’m so glad you asked these questions because……the big media explosion was pretty devastating, wasn’t really……I mean it was great got loads of people interested……but it also made led to loads of confusionWe would never, ever propose that tree planting works everywhereWe’re just showing the full potential it’s not like 200 gigatonnes……are really going to come out of the atmosphere immediately……it would be amazing if we even reach 10% of that full potentialAnd so we need all of the possible climate-change solutions in concertBut I do believe trees are more powerful than anything else……that I know of because they’re such a low-tech, easy-access solution……anyone can get involved in it, you feel good about yourself……when you give a dollar to a tree to plant a treeIt’s more important than the simple carbon sequestered by treesIt’s the advocacy that it promotesI don’t believe we’ll address climate change until we all feel……positive and engaged in the challengeI think it’s a beautiful way to open the door to get us engagedThe message that Tom was keen to communicate from his study… …was clearly both broader and more nuanced… …than some of the headlines suggested But is he right to argue that trees are more powerful… …than anything else in engaging people in the climate crisis? We’ve written on the merits of different approaches… …to this challenge across the globe So Asher and I sat down with one of our senior editors… …Oliver Morton, who specialises in climate science and policyYeah well I mean there were headlines on the Crowther……of the single most important thing people can do about climate change……is to plant trees and that’s not really……the single most important thing people can do about climate change……is to find ways to move humanity, humankind off the use of fossil fuels……which isn’t to say planting trees isn’t goodBut you know by and large getting off fossil fuels is very importantBut I think that’s true of almost anything anyone says……about any single actionIt’s a good thing but there’s no magic bulletI think key things to take into consideration when people talk about……planting trees is what else is going on on the land……where they want to plant the treesThe other thing is that sometimes planting trees……you plant the wrong sorts of trees and in some parts of the world……planting trees makes the world warmerSimon Lewis actually pointed us to some studies which have……if you’re talking to Simon Lewis I’ve no idea why you’re talking to me anywaySimon knows far more about trees than I will ever knowSo Simon Lewis is an expert in global change science……and he’s been talking us through a lot more of the details on thisIn fact, we’re putting up on the website some articles……and other research materialsIf you want to take a look at them then click on the info-card……in the top right hand of this screenBut for now, we’re on the way to film an interview with SimonIncreasing the forest area on Earth is really important……but we should remember that tree planting is not always goodIt’s all about the how the trees fit with the local environmentThat often means balancing competing interests for the land… …where those trees might be planted… …and considering the needs of local communities But it also matters where in the world those forests might grow There are three main types of forest on the planet Encircling the north, the vast boreal forest… …is disproportionately rich in carbon… …and covers large swathes of Russia, Canada, Alaska and Scandinavia Diverse temperate forests grow sporadically… …throughout the parts of the Earth with more moderate climate And tropical forests grow along and close to the equatorIn the tropics the trees are growing very fastAnd because they’re growing fast because there’s lots of resources……lots of sunlight, lots of water and they’re also transpirating……water to the atmosphere which is helping coolThat cooling occurs in part because the clouds… …formed by this water in the atmosphere… …reflect the sunlight In the colder north it’s snow rather than clouds that offer the most reflection Growing the boreal forest means less snow… …and more dark, absorbent tree coverWhich means there is less of a cooling effect……and there’s more of a warming effect which partly offsets……the carbon storage in the forests in the boreal zoneAccording to one study, in tropical forests that grew… …more than 40% the temperature decreased by just over one degree Celsius In temperate forests it decreased by around half a degree But in boreal forests the temperature actually increasedOne example of a restoration project that is going quite well……is in Uganda on the edge of Kibali national park……just 20 years after the initial planting and it’s moving back towards……a mature forest and a very high-carbon storage forestSo it’s really possible to go from almost nothing……to a really impressive forest in just a matter of decades in the tropicsIn your view what are the main misunderstandings around tree planting?It’s great that everyone loves trees and loves tree plantingWhat people forget is that the emissions are going……straight out in the here and the nowThose trees might absorb those emissions eventually…….it may be 20 or 30 maybe 50 years but there is a big time mismatchWe need to reduce fossil-fuel emissions dramatically and fastAnd then some of those residual emissions that we can’t mop up……and can’t reduce, then we could use some tree planting to do thatSo there can be a more limited role for trees… …in helping to reduce carbon emissions But even that’s dependent on the type of trees and forests that are grown Which is why Simon has sent us to check out an interesting… …and very English projectI’m here in Sussex, south of England at the Knepp Castle Estate……there’s the castleThis estate is a former farm……it was a standard farm about 30 or 40 years ago……and the owners allowed the woods and the fields……and the naturally occuring flora and fauna to flourish here……by leaving them aloneWe’re here to talk about taking carbon out of the atmosphere……and how much success it can have, not just here but on a global scaleWilding is a hands-off approachIt’s become a sort of environment that is a nursery for open-grown……freely regenerating treesWithin 20 years, we have doubled our carbon sequestered in the soilWe’ve got the scrub, we’ve got the grasses, we’ve got the trees……all that will be contributing to this carbon sinkThat’s actually the start of another film… …which you can watch by clicking the link opposite In it we look at why this hands-off approach is effective… …and some of the big challenges in terms of forestation At the other link you can see The Economist’s latest writing on climate change Thanks for watching and don’t forget to subscribe… …so you can get all our latest releases

100 thoughts on “Climate Change: can nature repair the planet? | The Economist

  • On Friday at 1:00pm GMT we are hosting a live Q&A about the issues surrounding climate change. What do you want to ask our experts? Oliver Morton, a senior editor at The Economist who specialises in climate science and policy, and Sarah Collinson, the director of this film, will be live to answer your questions.

  • Great story! Well balanced and realistic. Every time humans think and act against Nature and its natural flow, its natural intelligence, disaster is planted.

  • How tree planting will prevent that population of africa will be 4100 million by 2100?
    In mezozoic era there were jungles all around with 40*C average temperature. So this planting trees all around is more like a finger crossed situation because they have no idea but it sounds cool.
    The arrogance that these temp. intervals what they consider normal are the defaults of the earth is mind blowing.
    The last ice age started 2,6 million years ago and started to become milder 19000 years ago until 11700 years ago was over. So it took 8000 years to change completely but i guess the last 300 years is the end of the world.

  • Can you give us the best tree to plant for best oxygen to carbon ratios? Would love to hear those quantified numbers you speak of.

  • u need to plant where the roots do not cause damage people plant in cemeteries housing estates and such and forget about the roots smashing sewer pipes damaging property into coffins plant where the roots not cause damage

  • Great job… keep doing it… that is the way in my mind…. but remember one thing: you are journalist… right?… So study all the possible approaches… May be you don't like… but you must talk with people with other opinion… and forget your boss!!!!!… 
    At the end the question is: are the trees one solution or not? and why? may be is a part of the solution… may be with changes… may just for Occident world… may be… the perfect general solution does not exist… we cannot stop the world, the climate, the Earth, the clock, the people going to 10,000m… that is the naiver idea of the most of the catastrophic climate warriors… WE NEED SOLUTIONS and Advances… BE POSITIVE MY GOOD!!!!…

    e.g. look at the last ONU report about the CFC improvement… Why not? YES WE CAN do it? making changes… not stopping the world… not with a new colonialism or green dictatorship….
    In my point of view… If the climate change is a global problem it is because has global variables and global actors… but don't forget that there will be different repercussions for different people and areas… and also may be some actions will have some unknown reactions at the moment…

    Be honest, look for the truth, tell us, and be calm and neutral… remember that the science is a long path plenty of errors… like "the man cannot flight!!!", or "the railway cannot work!!!". In science the majority does not have the truth…

    GREAT JOB!!!!

  • In New Zealand, the government is funding the planting of 1 billion trees by 2028 of which 60% will be native and 40% be introduced mainly Pinus Radiata (Monterey pine). Whilst native trees take longer to grow but they live longer in some cases up to 1000 years so they can store more CO2 compared to the quicker growing introduced Monterey pine which can grow quicker than natives.

  • Ooh, a tad disappointed that they didn't discuss Emma Thompson's somewhat controversial claim that it's ok for her to fly all around the world whenever she wants because she "can afford to 'carbon offset' her co2 contribution by paying for trees to be planted"….

  • Potential problems with planting trees
    Trees do not appear from nothing. They take up important resources like land and water
    Trees have low albedo which means they absorb more sunlight and reflect less of it back into space which keeps it in the atmoshpere and warms the earth

  • Climate emergency, haha….the only emergency is the number of gullible idiots running around. Instead of reinforcing their argument that side now marches out the 16 year old climate crisis advocate recently (while skipping school?) for the emotional appeal. Surprised they didn't separate her from her mom at the border first before putting a micophone in her hand. So I advise you to drop the words emergency, crisis, from your headlines and mention the sun once in a while. My reference is "Don't Pee on my Leg and Tell me it's Raining", by Judge Judy. And Tom Steyer is appearing quite desperate lately… Steyer's position on the debate stage will be so far over to one side that he will be saying hello to people using restrooms. But I think CNN will sweep all honors at the Climate Awards show on HBO this year, with Wolf Blitzer just edging Andersun Cooper for best acting job by a host.

  • I live in both Japan & Philippines. What I mean by this is I have two houses, both are separate in the countries. I have to go to both every year because I am half Japanese half Filipino. I could've stayed in Philippines forever, but I was born in Japan & I have citizenship there. I'm still pretty happy though :p Ever since, I've noticed how both countries have a difference.. Japan is more clean, but still has a lot more green. Philippines isn't as clean, but has more green the Japan. No matter how clean your country is, you can make it really green & natural. Although, it just may be because Japan is temperate while Philippines is tropical, I believe maybe in the difference of culture Philippines has more experience with the green in our land. No offense to Japan, I love Japan! But this is just a message: Make your ways clean, but green.

  • Biggest scam ever this bull shit. Next they will put bull shit tech in our atmosphere and charge us taxes for breathing. You will see whats coming.

  • Let’s face it.
    When you hit “play” not because you care so much about trees etc but because of the most beautiful “economist filmmaker” staring at you.
    Good job Economist!)))) Sarah is so charming and pretty especially with lose hair and black/red colors, it is very difficult to concentrate on the content. But then, how do you compete for attention with the bloody zillions of sexy bloggers…? Given the number of views… didn’t work?

  • To The Economist: The first "link" you refer to at the end is not a link at all. Please watch the video through to the end and then either change the dialogue of this video to the correct information or CORRECT the "link" so that there is an actual link there. Thanks.

    James Delingpole 20 Sept 2019

    Across the Western world tens of thousands of brainwashed kids are bunking off school 20 Sept 2019 in what has misleadingly been described as a ‘Climate Strike.’

    No. A strike involves the withholding of productive labour. These kids are simply playing truant using the best ‘dog ate my homework’ excuse evah: ‘If I don’t do this, the planet will die!!’

    To give us an idea of just how ignorant these kids are on the so-called ‘climate emergency’, Guardian Australia has helpfully released a video.

    Daisy, 9, thinks:

    “It is making fires in the Arctic where there is supposed to be no fires at all, only snow.”

    James, 10, explains:

    “Carbon goes into the world’s atmosphere making the world get hotter.”

    Hannah, 10, says:

    “Some cows are farting and that’s putting carbon into the atmosphere and that’s bad because the sunlight goes out and can never come back.”

    Is this the kind of expertise on which we are now expected to base global climate and energy policy? Lots of greenies and leftists (not that there’s much difference) clearly think so.

    That, after all, was the purpose of the Climate Crisis Hearing held in Congress earlier this week – in which a Democrat-led committee invited us to be impressed by just how much a bunch of mopey, whiney teenagers including Greta Thunberg are worried about climate change.

    It’s also, presumably, why Jon Lansman – one of the sinister, rich, string-pullers of Jeremy Corbyn’s Labour party – considered it appropriate to show us a letter his 5-year old granddaughter had been programmed to scrawl.

    I believe that all children should be free to bunk off school to attend today’s Climate Strike. But only if they can get at least 80 percent of the answers right on this climate quiz prepared by the Global Warming Policy Foundation.
    Here is a taster:

    1. By how many degrees has the world warmed in the last 20 years?

    a) 0.3°C b) 0.8°C c) 1.5°C

    2. How many degrees Celsius has the world warmed since the pre-industrial period?

    a) 10°C b) 3°C c) 1°C

    3. It is thought that there were between 5,000 and 15,000 polar bears alive in 1960; how many polar bears are alive today?

    a) more than 28,000 b) 5,000 to 10,000 c) fewer than 4,000

    There is, I would suspect, barely a child alive that has been through the green indoctrination process which passes for education in our schools who would be able to answer more than half these questions correctly.

    (The answers are, of course, 1 a, 2 c and 3 a)

    So what we’re witnessing today is the bizarre phenomenon of tens of thousands of schoolchildren protesting over an issue which they do not remotely comprehend. And then being applauded for it by adults who – astonishingly – are even more stupid than the kids.

  • Well , at last , we simply cannot relate global carbon content with the forest area . How to reduce global carbon ? Why should we plant trees ? Both these questions have multiple explanations and we need to explore it and expand our knowledge of how the nature works .

  • Did you see the major story of Professor Peter Ridd's being sacked for exposing the
    lie of the Great Barrier Reef dying? He and many other scientists are spreading
    the word of the political forces that want to drive us down by using
    non-science sound bites, Al Gore and people like you.

    The ‘Climate Alarmist’
    group is driven by the concept of “Noble Cause Corruption”. They are so
    convinced of their righteousness that it is more important than the
    confirmation of data or solutions. People will use unethical or illegal means
    to attain desirable goals, as a result it appears to benefit the greater good.
    When people lose faith in the system to fix a problem, the concept will appear.
    An unfortunate example of this concept is ‘Police misconduct’ in which they
    neglect ‘due process’.

  • Great report. In Ireland, our government is planting spruce trees everywhere. Making money with monoculture thus turning my country into an ecological dead zone. This is the danger in politically driven climate action that needs to be addressed

  • There is a lot of compelling doubt about climate change, and the spooky political drive and fashion behind it.
    1. Consider what people say in counter argument https://www.youtube.com/watch?v=RkdbSxyXftc
    2. This guy looks at ice data https://www.youtube.com/watch?v=vwUhJaQVi-M
    3. An interesting pop skeptic https://www.youtube.com/watch?v=3yq3nERlJC0

    Arguments seem to come down to just "We're right, Scientists say this, World blows up in 11 year, shhhhh" – they never show credible data.
    It's a one-way road. There is a very spooky political drive with a lot of money arranging this stuff and arranging creepy protests.
    They don't engage with opposite debate, they just try to conceal it and tell you "don't look at them… thats bad… look at us." That's not an argument

  • This planet does not care whether humans exist on it. This planet is a minor speck in the Cosmos. We either live or die by our own behaviours.

  • This is what frustrates me. Our star the sun that thing that makes daylight. It goes through Cycles of hot and cold the called solar maximum and solar minimum. Some of these Cycles last longer than others. Our star the sun is in a cycle phase 25. Now this means but the sun is not very active it's quiet. But another phenomena as the sun rotates every 27 days we Face coronal holes that come into Earth's View. These coronal holes create magnetic fiangle magnetic connections. Every 27 days we get this fast space Wind full of high energy particles. Creating all kinds of things that we don't understand that needs studied. That's just the tip of the iceberg. Now we have to keep a new account that are magnetic field the Magneto sphere of our planet that protects us from these high energy radiation particles from the sun's c m e coronal mass ejections is in a pole shift. What the magnetic field there's a phenomenon called the South Atlantic anomaly. There's some suggestions that may indicate the magnetic field and its pole shift may be dragging weather with it in the jet stream. Let's add this one into the into the total of f*** ups. When Exxon Mobil had their oil spill in the Gulf in our lovely beautiful once beautiful ocean they expelled trillions and trillions of gallons of oil into the ocean currents. drastically changing the temperature of the water. Affecting a process called convection that's the ocean currents transferring Heat and coold to the South and North Pole. so let ExxonMobil come up with some f**** money to fund some of us scientists so we have the proper tools to do our jobs. Exxonmobil's oil spill what's a huge disaster. You can see it from space to this freaking day. what about Fukushima. how many of you realize that Fukushima that there's four nuclear reactors that are still leaking cesium into our water system. These are huge problems I think that are electric and utility companies need to pay a heavy price. let me put this last nail in. The sun's magnetic field it's called the heliosphere. The sun's magnetic field protects us from Interstellar space radiation known as gamma radiation and neutrino particles. These particles in high energy are deadly to DNA in life. This is very important we need to measure this gamma radiation this probably getting rain down on us every day we need an accurate measurement of this. There's a device at this goofy English scientist came up with which was genius and called muon detectors. These instruments have sophisticated Electronics two detectives neutrinos and Gamma particles deadly radiation from Interstellar space big problem people big problem

  • Go to ecosia.com and download their search engine. Their website will tell you everything you need to know about them, how they spend their money etc. Unlike Google that keeps the money from the advertising on searches for themselves, Ecosia uses it to plant trees. So far they have planted 60 million trees! I am not an employee just a fan of any way to help with the climate crisis, and just changing your search engine to help plant trees is a great way of doing it!

    Thousands of children came out for the Climate Strike across the world today. Scary that there are thousands like this coming up, indoctrinated, across the world…

    Will she even be able to get a job after she gets her degree?

    And this is what this type of fear-mongering creates:

  • In this weeks Economist there is a chart showing glacial periods, and interglacial periods. We appear to be at the end of a long interglacial period. The next cooling period seems to start when CO2 has peaked. Is it about to get a lot colder?

  • the climate change nutjobs think the planet will end in 11 years

    how arrogant to think we can destroy the planet

    little known fact

    the earths co2 levels are at historical lows

    in the past the earth hjas endured co2 levels at 7000 ppm

    yes thats 20 times greater than today. guess what? we are still here

  • I really don't know why was that boy there with that hot chick. What was his purpose exactly? He keeps quiet all the time he is with the girl and she does all the work and talking.
    Was that done under some kind of feminist agenda at the expense of that boy?

  • What did you say? “Restoring the local habitat is good. Not a silver bullet like no one thinks that. Mono culture bad.” Great video but who’s is it for? People who believe in climate change but also believe no other solution is valid besides tree planting; not forest planting; tree planting also. Also those squares are cute and all but you need some sustainable tree farms for resources for humanity not just all natural forests so more realistically both are needed or a hybrid is needed and tree farms are part of the solution. Either tree farms and habitat restoration/ habitat that is built with a dedicated tree farming section. Agriculture and habitat restoration/ habit that simultaneously provide human food.

  • Vanished; the sixth extinction crisis, it's far worse do you think/@mifuerzamorales check the documentary post! Read the sixth extinction; an unnatural history/Elizabeth Kolbert!! If continue,the humanity migrate in millions!!!millions!!!Have more problems for water, land, food,territory!!!the end era!!!!!

  • People exhale Co2 and it may sound bad, but we are gonna eventually have to start euthanizing people to save the planet and our species.

  • Simon Levis is quite right about the urgent need to reduce fossil fuel burning. But he is NOT talking about powerful climate effects of trees besides Carbon sinking. And that is a fatal omission. CO2, methane, nitrous oxide and the whole bunch of the so called Greenhouse trace gases respond in totum for only 20% of heat trapping in the atmosphere. But water vapor (yes, gaseous H2O) traps from 66% up to 82% of heat globally. Every climatologist will acknowledge this as a fact, but will stop there, often arguing that water vapor is a unavoidable added greenhouse gas, which concentration trails behind other warming or cooling factors. The BIG omission is that trees interfere DIRECTLY in water vapor concentration in the air, producing a range of cooling effects not properly accounted for by carbon-centric approaches. In fact, trees, if their cooling effect through vapor were computed, could surpass by far their indirect effect on reducing other GHGs like CO2. This omission is a GRAVE mistake.

  • Guys, the real reason for pushing climate change is to force the world to give up one day as a day of rest. The Vatican is pushing this on politicians so “SUNDAY REST “ can become a law for the whole world. The Vatican is using Freemasons to promote this evil agenda so they can get back into power.

  • Trees are dying, they can't adapt to a fast changing climate.

    Three simple facts about climate change: 1. 3 C and more are already locked in because of the 20 year time lag between CO² emission and effect. 2. Dozens irreversible feedback loops are now accelerating the process, it's called "Exponential Climate Change". 3. WASF.

  • A video produced by the ill-informed for the ill-informed. Tree planting ideas ignore multiple elephants in the room.. current and future deforestation happens on a scale that dwarfs any tree planting. Even more damning is the unfortunate reality that any proposed solution which gives the impression that our economies can continue mostly as they are, are flawed, since it is our economic and cultural business-as-usual which is turning the biosphere into something that will not support large-scale human life. The tree planting idea is for the naive masses who don't want to consider the bigger picture that consists of a never-ending list of unfortunate realities.. year-on-year rising emissions, literally dozens of climatic positive feedback loops that are accelerating change, rising global population, rising global average living standard driving exponential consumption, collapsing arctic (release of methane from permafrost, drop in albedo, ..), increase in wild fires (causing soot to darken Greenland ice sheet, accelerating melt), .. The list goes on and on, for those willing to confront reality, and not swallow the too-good-to-be-true stories of easy possible solutions.

  • In a warming world trees are proving notoriously flammable. Extreme drought and floods are not to their liking either. The loss of farmland in a hungry world will see food prioritised over forests. And new studies show trees may not be as good at sequestering carbon as previously thought. Let's just face it – We Are So Fucked.

  • I thank Economist for clarifying my thought on the use of fossil fuels. It is actually bothersome and what could be the large part of carbon emission. It's even funny to think the Oil and Gas industry are sort of a rich, money earning job…

  • To much vested interest in fossil fuels.Politicians won't react only if they benefit from it.This issue has to be forced because it will never happen voluntary the can will be kicked down the road.

  • IT'S REALLY QUITE ALARMING TO SEE JUST HOW POLITICALLY GULLIBLE SO MANY PEOPLE ARE. CARBON DIOXIDE, CO2 IS A NATURAL, HARMLESS, ODOURLESS AND INVISIBLE GAS. CLIMATE IS CONTROLLED BY THE SUN NOT CO2 THAT IS A VERY SMALL PART OF OUR ATMOSPHERE..
    WHY DO WE NOT ACTUALLY SEE THESE SO-CALLED EXPERTS WHO HAVE THE TEMERITY TO LIE ABOUT CLIMATE CHANGE BEING CAUSED BY MANKIND. WE NEVER SEE THEM BECAUSE ANY TRUE SCIENTIST KNOWS FULL WELL THAT CO2 CANNOT CHANGE THE CLIMATE. THE ATMOSPHERE IS 95% WATER VAPOUR. WHAT WE DO SEE ARE REAL SCIENTISTS TELLING US THE TRUTH WITH SCIENTIFIC FACTS. THE OTHER PHANTOMS EXPERTS ARE JUST PROPAGANDA.
    THE CLAIM THAT MANKIND IS CAUSING GLOBAL WARMING IS MADE BY COMMUNISTS TO SCARE PEOPLE INTO ACCEPTING A ONE WORLD GOVERNMENT, GLOBAL COMMUNISM. AND THESE SILLY YOUNG DUMBOS, WHO SHOULD KNOW BETTER, ARE DOING JUST WHAT THE COMMUNISTS WANT BECAUSE THEY ARE SO POORLY EDUCATED AND JUST SO GULLIBLE AND NAIVE.
    WHEN ANY "EXPERT" MAKES A PROFOUND CLAIM, THE FIRST QUESTION FOR ANY THINKING PERSON TO POSE IS WHO IS SAYING IT AND WHO IS FUNDING THEM. WAKEY, WAKEY YOU PEOPLE BEFORE YOU DESTROY THE PLANET WITH EVIL LEFT-WING POLITICS.

  • keep dreaming. Watch politics all over everywhere. Rightist conservatives have taken control. Idealism and realism are being "framed" as socialist or communist ideas and fought like in the past with all methods at disposal. And in Spain, it's working like everywhere else. Poor Spaniards are being brainwashed with the same propaganda methods from the past century. Lies lies and more lies of a political estáblishment with no brain force bud to keep themselves in Job for a Year and keep covering up the corruption from the past decades, the ones still not jet prescribed….its over no matter how hard we try. A monkey cant have talk with an amoeba. Conservatives are the biggest threat to human species and will bring humans to the edge, and a step forward we have made for them.

  • We need to stop planting trees.
    We need to put ground under protection and let nature come back.
    STOP TREE PLANTATION.

    Please help spreading this information.

  • 30 years ago the big concern was the loss of forest and jungle and grasslands. Now 30 years later the earth is greener and no one gives a shit.

    https://www.nasa.gov/feature/goddard/2016/carbon-dioxide-fertilization-greening-earth

    The globe has gotten 14% greener in the time period between 1982 and 2011 according to Nasa. As CO2 goes up, the number will go up. It is called a negative feedback. Forget about MSM, including the Economist, reporting on this.

    Also crop production has increased substantially due to CO2 increase. So good news.

  • Hello, my names James, I’m writing this on behalf of ‘Restore Sustain Thrive: Brazil Reforestation & Permaculture'. Restore Sustain Thrive is social-environmental development project here in Brazil. The main focus of the project is reforestation and the promotion of permaculture in the Atlantic forest (Mata Atlântica) region to the north of Rio de Janeiro. To get things started we are conducting a crowd funding campaign. We would greatly appreciate any assistance you can give and if you could distribute this to friends, family and to any individuals or organisations that you think may be able to assist. While we at Restore Sustain Thrive have been developing and planning RST projects for quite some time, the current situation in Brazil brings home the urgency of the need to protect and restore the forests here and the world over. Thanks a lot, James – Learn more at https://www.restoresustainthrive.org/

  • Someone said, the solution is not to plant trees the solution is to conserve our forestry and let the nature take it cause. 2nd removing fosil gases is not easy as we think, the best is to do away with coal and adopt nuclear power. Wind vane and solar will never cutter for our use of electricity and energy, the future is nuclear energy

  • The world should enforce law that every country should have 25% land mass of natural forest. Planting trees isn't enough

  • Can nature save the planet,

    Who says the planet is in danger?

    And the answer to problems have always been taken care of nature, NATURALLY, by God

    So you, the climate changers, just answered their own question and wrapped up their false claims of climate change.

  • God has created the planet to heal itself. There is no problem with global warming/climate change… except for the liars that are pushing it down our throats.

  • Canada issued loads of polar bear hunting licenses this year because there are so many bears and they are very dangerous to the eskimo and folk who live in their hunting ground. Greta said the image of the last polar bear from previous years climate agendas made her so sad, guess what Greta the polar bears are coming to eat you, you foolish girl. She has challenges and this is what her parents do to her. Children are being prescribed very strong drugs because they are so hysterical about climate change, well done Greta, your work is done. How will she feel when the first suicide with a note from a child comes out because there is no future, only 12 years left. You people who push this absolute crap climate change agenda are all criminals and I hope you all get prosecuted. I call on all parents to parent and stop letting rich people with agendas ruin your childrens lives. WAKE UP.
