18 million square kilometers more greenery due to “carbon pollution” that the Greens hate

What kind of pollution do you want to feed your plants? The carbon kind.

Yet again, a satellite study of leaf area shows that the world is greener than it was in 1982. There are more plants mostly thanks to CO2 aerial fertilization. The biggest benefits from CO2 are in the warm tropics. The extra greenery in colder areas was due to that other disaster called “global warming”. About a tenth of the greening had nothing to do with either carbon pollution or extra warmth and was apparently thanks to nitrogen from man-made fertilizers.

Obviously we need a $10 billion dollar program to stop this immediately.

Humans are Greening planet Earth — ABC

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 [...]

Burn oil, feed the world, grow plants, save forests, get richer, live longer. Why we urgently need to raise CO2.

It’s time to stop pussy footing around. We need higher levels of CO2. It is morally and ethically irresponsible to be silent while millions starve, biodiversity is under threat, and people are dying from cold weather.

Carbon dioxide increases crops, forest and plant life by 14% and is worth $140 billion, just in agricultural production. Thanks to CO2, forests have been protected because farms are more efficient in a higher CO2 world.

Countries that don’t do their part in producing enough carbon dioxide emissions need to lift their game. Coal use should be favoured over nuclear, hydro, wind and solar. Countries like France are free-riding on the nations like China, the US, and Australia — which are helping to green the world and feed the starving.

Indur Goklany has put together a comprehensive report on the benefits of CO2 for the GWPF.

The advantage of higher CO2 for all C3 crop plants is spectacular. That’s rice, wheat, barley, rye, cotton, sugar beet, spinach, and potato. C4 plants evolved in the last 30 million years to be good at dealing with low CO2 atmospheric concentration (corn, sugarcane, cabbage, broccoli, sedge, daisy.) Most plants are C3.

Welcome to the CO2 disaster — 4 billion tons more plants, more greenery

During the recent warmest decades on record, Earth suffered under the highest CO2 levels of the last 800,000 years. Life responded to this devastating situation by — flourishing. There are now some 4 billion tons more living matter on the planet than there was in 1993. What a calamity. (And what a lot of carbon credits.)

It has, naturally, got nothing to do with warmth and aerial fertilizer. The researchers tell us it due to that force of nature known as “good luck”. Remember, human CO2 emissions were pollution that was going to afflict life on Earth. After twenty years of predicting the loss of forests and species, it turned out that biology bloomed instead. Notch up another model “success”. The press release headline: Good luck reverses global forest loss. (What else would we expect from UNSW?)

To those who know basic biology — and that almost half the dry weight of plants is carbon, sucked straight out of the air — this is not so much good luck as one entirely foreseeable and foreseen consequence of rising CO2. Acquiring carbon is often a plant’s hardest task. When the sun comes up, a cornfield begins sucking, and by lunch time [...]

Peak Wheat! One quarter of wheat production will be lost to extreme climate (or maybe Not)

According to a new study released by Nature Climate Change we are, remarkably, at the very peak of conditions for wheat growth worldwide — and it’s all downhill from here. (What are the odds?) The last 15 years, which have been the “hottest on record” and saw massive human CO2 output, were the peak time for wheat. But all that is about to fall off a cliff if we do … more of the same.

To demonstrate that millions will starve: take projections of extremes from broken climate models, and put them in wheat crop models, and then assume we take no adaptive measures for the first time in human history. Ignore that even the IPCC doesn’t think extreme events are necessarily changing: “Climate models are unable to predict extreme events because they lack spatial and temporal resolution. In addition, there is no clear evidence that sustained or worldwide changes in extreme events have occurred in the past few decades. “

There’s been no increase in drought globally in the last 60 years either. Pouring free fertilizer into the sky, along with better agricultural practices, has produced a global boom in crops (See CO2science for scores of studies on biomass [...]

Write to a tree about climate change in the Melbourne City Council, and it will write back

Wait for it… “dozens” of Melbournians are writing emails to trees and the trees are writing back (thanks to paid staff who can speak Elmlish, Oatin, and Planely). Lots of trees are being told they are set to die off thanks to climate change. The Stress!

Broadsheet Melbourne

Right now, you can log onto the City of Melbourne’s Urban Forest Visual map and email any tree you’d like within the council’s boundaries.

Yep, all 60,000 of them.

The Gulf Today. AE

But almost a quarter of its trees, including oaks, elms and planes, are set to die off by the end of the decade, and that figure will rise to almost 40 per cent by 2030, speeded by a devastating 13-year drought that broke in 2012.

“As our climate becomes more and more extreme, we’re going to have to look at trees that are fit for purpose,” Councillor Arron Wood said.

So you can write to a tree in Melbourne and it will write back:

The quirky emails, to which staff respond on behalf of the trees, are building awareness of climate change in Melbourne, regarded as Australia’s most European [...]

Look out, a soil model says more plants means massive carbon stores might be freed

The Doom message version 48.2a (subclause i) has been released.

Forget methane clathrate pits, now extra plant growth (blame CO2) could cause global soil to unleash massive amounts of carbon.

Carbon dioxide (aka “pollution”) feeds plants. This is now bad (didn’t you know?). An all new “first” computer model with plants, soil, and fungus, warns us that more plants could get soil microbes excited which might break down more soil carbon and release it into the air. Disaster! It’s a could-be-might-be-catastrophe. (At least until paragraph 6 — see that caveat below.)

In the meantime this is is so big, it’s practically nuclear — the model reports that it could set off a “chain reaction”:

An increase in human-made carbon dioxide in the atmosphere could initiate a chain reaction between plants and microorganisms that would unsettle one of the largest carbon reservoirs on the planet — soil.

Did you know there is twice as much CO2, carbon in the soil as there is in Earth’s whole atmosphere?

Researchers based at Princeton University report in the journal Nature Climate Change that the carbon in soil — which contains twice the amount of carbon in all plants and Earth’s [...]
