Climate change beyond point of no return

Climate change escalating so fast it is 'beyond point of no return'

Global warming is beyond the “point of no return”, according to the lead scientist behind a ground-breaking climate change study.

The full impact of climate change has been underestimated because scientists haven't taken into account a major source of carbon in the environment.

Dr Thomas Crowther’s report has concluded that carbon emitted from soil was speeding up global warming.

The findings, which say temperatures will increase by 1C by 2050, are already being adopted by the United Nations.

Dr Crowther, speaking to The Independent, branded Donald Trump’s sceptical stance on climate change as “catastrophic for humanity”.

“It’s fair to say we have passed the point of no return on global warming and we can’t reverse the effects, but certainly we can dampen them,” said the biodiversity expert.

“Climate change may be considerably more rapid than we thought it was.”

The report, by an exhaustive list of researchers and published in the Nature journal, assembled data from 49 field experiments over the last 20 years in North America, Europe and Asia.

It found that the majority of the Earth’s terrestrial store of carbon was in soil, and that as the atmosphere warms up, increasing amounts are emitted in what is a vicious cycle of “positive feedbacks”.

The study found that 55bn tonnes in carbon, not previously accounted for by scientists, will be emitted into the atmosphere by 2050.


“As the climate warms, those organisms become more active and the more active they become, the more the soil respires – exactly the same as human beings," said Dr Crowther, who headed up the study at Yale Climate & Energy Institute, but is now a Marie Curie fellow at the Netherlands Institute of Ecology.

“Our study shows that this major feedback has already certainly started, and it will have a significant impact on the climate in the coming decades. This information will be critical as we strive to understand how the climate is going to change in the future. And it will also be critical if we are to generate meaningful strategies to fight against it.”

Dr Crowther, a 30-year-old Cardiff University Phd graduate originally from North Wales, predicts climate change will lead to widespread migrations and antagonism among communities.

“These effects of climate change will certainly be felt disproportionately by poorer people, particularly the billions of people whose livelihoods are intrinsically linked to the land,” he added.

“But the impacts on sea-level rise, ocean currents and the health of natural ecosystems are equally devastating for a vast multitude of reasons.”

During his presidential campaign, Mr Trump described climate change as a “total hoax” and said it was a concept created by the Chinese to manipulate US markets.

The billionaire tycoon also tweeted in 2014: “It’s late in July and it is really cold outside in New York. Where the hell is GLOBAL WARMING???”

White House chief of staff Reince Preibus has since said the 70-year-old will “have an open mind” but Mr Trump’s threat to pull out of the 2015 Paris climate deal still lingers.

The increasingly popular right-wing Breitbart News website's reporting has repeatedly poured scorn on climate change theories.

“I think this is catastrophic for humanity,” said Dr Crowther.

“Uncertainty is nothing like a reason enough to suggest climate change isn’t happening. There’s a nice analogy; if you step in front of an oncoming bus, no doctor in the world can tell you how damaging the impact is going to be.

“But we do know the damage is going to be huge. This alone should be enough information to persuade us to avoid the bus.”

Climate change: It's "game over" for planet earth

What's the effect of global warming on our seasons?
The last two decades of the 20th century were the hottest in 400 years.

He added: “Sceptics often say that scientists are just saying that climate change is real so that they can keep their jobs.

“I would just like to stress that I could get a hell of a lot more money than academia offers me if I were to do a study that suggests that climate change is not real."

Prof Ivan Janssens, seen as one of the godfathers in the global change ecology field, said the research had provided essential data to the climate change model.

The Intergovernmental Panel on Climate Change (IPCC), established by the UN and World Meteorological Organisation, is incorporating the study's data.

“This study is very important, because the response of soil carbon stocks to the ongoing warming, is one of the largest sources of uncertainty in our climate models,” said Prof Janssens, of the University of Antwerp.

“I’m an optimist and still believe that it is not too late, but we urgently need to develop a global economy driven by sustainable energy sources and start using CO2, as a substrate, instead of a waste product.

“If this happens by 2050, we can avoid warming above 2C...

Oh, NO. Natural CO2 emissions.

So these natural emissions, which are currently occurring, have not been factored into the anthropogenic sum. Of course they haven't really determined the other natural emissions either. Wink

Soil emissions increase as temperature rises.

Where's the documented evidence that climate change is not happening due to Blooby's car having frost on the windows?

I mean, that's real science right there.

No need to worry anymore, might as well just keep going.

Then there's no further point in all this arguing back and forth, is there?

I accept facts and truth. So according to the article-

So we need to go to adaptation as mitigation has not worked.

Now because they have not taken it into account; it is a further natural emission. Therefore anthro emissions must be lower.

It is sad to see you cannot deduce anything. Embarrassed

Correct

Now that thats all sorted out we can just forget about all this shite.

Sack all the climate scientists, sack all the renewable energy scientists.

Sack all the politicians and nerds that want to save the world and send the greenies off the planet.
