CLIMATE MINUTE Greening the Earth through CO2
CO2 helps plant grow. Aww shucks. the carbon cycle.
“Rising carbon dioxide levels in the atmosphere have increased plant growth across the planet over the past three decades, a new study has found.
Key points:
A few areas on Earth have browned but the vast majority have greened
Plant coverage has grown by 18 million square kilometres in a few decades
The main cause is increase in atmospheric CO2
Nitrogen from agricultural fertilisers has also contributed
The most comprehensive modelling of remote sensing data so far shows the area on Earth covered by plants in this time has increased by 18 million square kilometres — about 2.5 times the size of the Australian continent — largely due to the fertilising effect of carbon dioxide (CO2).
"[The greening] has the ability to fundamentally change the cycling of water and carbon in the climate system," said Dr Zaichun Zhu, from Peking University in China and lead author of the new study, which appears today in the journal Nature Climate Change.
Carbon fertilisation is the dominant process for greening across the globe, particularly in the tropics because there's so much leaf area there.
"This is a snapshot of humans' global influence on the functioning of the entire global biosphere," said co-author CSIRO's Dr Pep Canadell of the Global Carbon Project.
The new findings come from analysis of data from the past 33 years taken by three different satellite missions that measured the green light reflected by photosynthesising leaves.
Dr Canadell said the remote sensing data was run through 10 global environmental change models to identify the cause of the greening.
About 85 per cent of Earth's ice-free land is covered by plants, and each year photosynthesis soaks up about one quarter of the nearly 10 billion tonnes of carbon emitted by humans.
Drs Zhu, Canadell and colleagues found that the 46 parts per million increase in atmospheric CO2 between 1982 and 2009 was responsible for 50 to 70 per cent of the observed greening.
"Carbon fertilisation is the dominant process for greening across the globe, particularly in the tropics because there's so much leaf area there," Dr Canadell said.”
if there is good news about climate shouldn’t the media ring the bells and say hooray! But they spend more time just trying to take it down and find another study that has very bad news. Bad it good. Because it teaches you fear and to stay in your 4 walls.
Decide to WIN. Decide for Optimism. Decide that bad news is something you step on like the crickets they want in your apple pie. Decide to swallow whole their crap ideas and flush them down the toilet. Be the person that keeps getting up with incredible determination. TO WIN.
just win. WIN IN YOUR CONVERSATIONS. WIN UNAPOLIGETICALLY. win all the time.
win over your opponents. Do it with a smile and pizzaz. why not. Why the heck not. As they try to take what is good in life, we will fill the void to proclaim what is good in life. the new economy is in HOPE and fierce opposition to tyranny.
talk about the cameras dangling everywhere. Especially with the trades. Get people thinking. Plant the ideas that they will want to escape from this ideology and this exact prison type system.
what happens if you go to jail for speech. talk a lot there. everyone will have nothing else to do but listen.
GET FIT.
take down the beast.
Practice winning. visualize winning. win in small goals in your life. make them about your health, about your mindset, about pushing back darkness all the time. about helping others. As you help others, they will see the light because it will be from within.
We all must do this. win at the local level. Win in your home, win in your business. help local businesses. Get a room ate, or a house mate or a tenant.
also.
TAKE DOWN THE BEAST.
I did recently read a story about this. I don't remember who published it, but it started out like a good news story, but about halfway through, it reversed course and got very negative,saying something like 'although the greening of the earth is good for growing more food, it also proves warming, which is melting the ice, causing sea levels to rise, and releasing previously 'ice locked' microbes & contaminates into mountain streams', etc., etc., etc. So they still found a way to call it a catastrophe, lol.
