Global warming is accelerating and the unstoppable feedbacks will soon begin
The accelerated melting phase of the Thwaites Glacier in Antarctica began, it is the size of Florida, it can raise the oceans by 30 cm. and destabilize other adjacent glaciers whose melting would raise the water another 3 meters.
“Time is running out to avoid the worst effects of climate change,” the researchers from Oregon State University (OSU), the University of Exeter and other institutions said in the report published in the journal One Earth.
As the planet warms, sea ice melts and the loss of its white surface, which reflected more sunlight than the darker ocean, causes temperatures to rise. Result: sea ice melts further.
This kind of vicious cycle, called a “feedback loop” by scientists, is a growing concern for climate experts.
The researchers in their report believe it is the most comprehensive list yet compiled of these self-reinforcing chain reactions, and a stark warning that climate models may be underestimating their impact.
“Many feedback loops significantly increase warming due to greenhouse gas emissions,” they noted.
“However, not all of these feedbacks are fully accounted for in climate models,” they noted.
According to OSU’s William Ripple and Christopher Wolf, co-authors of the study, research on feedback loops needs to be “immediately and massively” boosted to help world leaders make climate policy.
In particular, they urged the Intergovernmental Panel on Climate Change (IPCC), the UN climate expert group, to produce a special report on the effects of feedback loops and their potential “serious consequences.” .
The researchers identified 41 climate feedback loops, of which 27 accentuate warming, seven have a damping effect, and seven have an uncertain effect.
Among the feedback loops they mentioned the thawing of permafrost (the permanently frozen layer of soil in polar regions), the die-off of forests, the loss of soil carbon, and the drying and slow burning of peatlands.
In the permafrost example, rising temperatures lead to thawing, which results in carbon dioxide and methane emissions that lead to further rises in temperatures, they noted.
The report warned that interacting feedback loops could result in a sequence of climate “tipping points” with catastrophic consequences.
“Once sufficient warming has occurred, feedbacks could ultimately cause the Greenland ice sheet to collapse,” Wolf explained.
The report highlighted that most nations have signed the Paris Climate Agreement, which calls for limiting global warming to +2C above pre-industrial times, and ideally +1.5C, but said more drastic measures to reduce emissions.
“Waiting until 2050 to achieve net-zero carbon emissions might be too late,” according to the authors.
In the near term, failure to drastically reduce emissions could result in continued and intensified climate impacts.
And “in the long-term worst case, interactions between feedback loops could result in an irreversible change from the current state of Earth’s climate to a state that threatens the habitability of humans and other life forms,” they added.
This report supports what was sustained through my previous notes and the urgency of activating the scientific team of the Gaia Team, so that they investigate, evaluate and determine the next threshold of climate anomie in a maximum time of 90 days. And then it is endorsed or refuted by the UN IPCC experts, also within a maximum period of 90 days, because our time is up. We have 5 years or less left to apply drastic cushioning measures on a planetary scale.
According to WMO predictions, we will break the threshold of 1.5 to 1.8º C in the next 5 years. Then great intercontinental structural droughts can occur. As a consequence, half of the world’s population can die of hunger as the few food reserves run out.
My priority concern is the possible activation of the “clathrate gun” at the North Pole. To measure this risk, I have put together the Gaia Tea scientific research team. To activate it requires a million dollars of financing. This scientific report is urgently needed. We are against the clock. A world where more than a hundred million dollars are paid for the purchase of a soccer player and nobody wants to donate a million dollars to save the entire planet is counterintuitive.
We must avoid breaking the threshold of 1.5º C and 2º C. We cannot allow it. For this we can activate the SCoPEx project and apply new adjustment measures of climate adaptation, taking zero carbon emissions as a goal for 2030.
Let us work together and in a cooperative and coordinated manner to save 8 billion human beings from the foreseeable tragedy of accelerating global warming. Together everything is possible.
The worst mistake we are making is believing that we have time to avoid the worst…
