from runaway climate change», this set up a global fund to save vast areas of rainforest from the deforestation which accounts for nearly a fifth of all man - made CO2 emissions.

The idea that the sunny weather they enjoy may be a harbinger of
runaway climate change, that their beloved happy meal hamburgers are responsible for the release of dangerous methane gases and the unjust monopolization of vital water sources, and that the plastic refuse
from their picnics might end up endangering the dolphins they idolize
from afar — well, it's a lot to lay on a child who's still not old enough to see the latest Star Wars.

«Trump has pledged to take actions to round up and deport millions of Americans, decimate unions, take health care coverage away
from millions, threaten women's reproductive rights, and allow
runaway climate change to continue — all while deregulating the economy and cutting taxes for the wealthy.
Eberle and Kim said the early - middle Eocene greenhouse period
from 53 to 38 million years ago is used as a deep - time analog by
climate scientists for what could happen on Earth if CO2 and other greenhouse gases in Earth's atmosphere continue to rise, and what a «
runaway» greenhouse effect potentially could look like.

runaway greenhouse, Nature Geoscience, doi: 10.1038 / ngeo2994, 2017
This article minimizes what credibly could be the largest challenge in dealing with
climate change: Holding the atmosphere to a CO2 content no greater than 450 PPM to prevent an increase of no more than 2 degrees C, beyond which
runaway growth in CO2 could occur
from natural sources.
Maybe inclusion of CH4 and a sufficient
climate sensitivity
from the other feedbacks would make it
runaway for some part (maybe not all) of the process.
Once the ice reaches the equator, the equilibrium
climate is significantly colder than what would initiate melting at the equator, but if CO2
from geologic emissions build up (they would, but very slowly — geochemical processes provide a negative feedback by changing atmospheric CO2 in response to
climate changes, but this is generally very slow, and thus can not prevent faster changes
from faster external forcings) enough, it can initiate melting — what happens then is a
runaway in the opposite direction (until the ice is completely gone — the extreme warmth and CO2 amount at that point, combined with left - over glacial debris available for chemical weathering, will draw CO2 out of the atmosphere, possibly allowing some ice to return).
Berger provides useful context
from Andrew Dessler, a
climate scientist at Texas A&M University, who noted that most people publishing on this question have long seen very low odds of
runaway or extreme warming:
The sudden release of large amounts of natural gas
from methane clathrate deposits in
runaway climate change could be a cause of past, future, and present
climate changes.
And we certainly never hear a word
from the «experts» about the ongoing
climate engineering assault that is exacerbating the now
runaway warming (in addition to contaminating the entire planet).
«In our era of
runaway climate change, it's critical for the Supreme Court to stop these outdated monopolies
from abusing the law and trying to strangle renewable - energy development.»
Technology will advance far enough during that time to make the issue of
runaway warming or
climate change tipping points
from human greenhouse gas emissions moot historical footnotes.
These tipping points could be ice sheets on Greenland and Antarctica melting permanently, global food shortages and widespread crop failures with more extreme weather, rising ocean temperatures and acidity reaching triggering a crash in global coral reef ecosystems, and warming oceans push the release of methane
from the sea floor, which could lead to
runaway climate change, etc..
According to David Wasdell, International Coordinator, Meridian Programme: «A
runaway climate change is now clear and beginning to be quantified for the first time... the greatest threat we face as a planet... The rate of change we're generating in the current situation is between 200 - 300 times faster than that experience of any extinction event apart
from the asteroidal impact.
In a sharp change
from its cautious approach in the past, the National Academy of Sciences on Wednesday called for taxes on carbon emissions, a cap - and - trade program for such emissions or some other strong action to curb
runaway global warming.Such actions, which would increase the cost of using coal and petroleum — at least in the immediate future — are necessary because «
climate change is occurring, the Earth is warming... concentrations of carbon dioxide are increasing, and there are very clear fingerprints that link [those effects] to humans,» said Pamela A. Matson of Stanford University, who chaired one of five panels organized by the academy at the request of Congress to look at the science of
climate change and how the nation should respond.
That no more makes them immune
from criticism than «a lifetime's study of
climate» makes
runaway Lacis.
Unfortunately for the Pope, James Hansen and other hysterical
climate doomsday soothsayers, the real world empirical evidence clearly shows that the world's
climate is self - correcting and not prone to those scary predicted tipping points and
runaway disasters
from growing atmospheric CO2 levels.
The enduring myth of «accelerating» is a leftover
from earlier IPCC
climate reports and the original AGW hypothesis that speculated greater levels of atmospheric CO2 would generate «
runaway» global warming leading to a catastrophic «tipping point»
climate change.
Runaway climate change would mean that governments would lose the ability to control future
climate change that they would otherwise have through reducing greenhouse gas emissions
from fossil fuel combustion and deforestation.
If the feedbacks
from higher carbon dioxide levels are strongly positive, then in past geological eras when CO2 levels were much higher than today there should have occurred the «
runaway climate» that James Hansen fantasizes about.
The
runaway greenhouse effect has several meanings ranging
from, at the low end, global warming sufficient to induce out - of - control amplifying feedbacks, such as ice sheet disintegration and melting of methane hydrates, to, at the high end, a Venus - like hothouse with crustal carbon baked into the atmosphere and a surface temperature of several hundred degrees, a
climate state
from which there is no escape.
Ingersoll [105] discussed the role of water vapours in the «
runaway greenhouse effect» that caused the surface of Venus to eventually become so hot that carbon was «baked»
from the planet's crust, creating a hothouse
climate with almost 100 bars of CO2 in the air and a surface temperature of about 450 °C, a stable state
from which there is no escape.
This
runaway effect that manmade
climate change believers talk about comes
from the hypothesis that
climate change feedback mechanisms are positive and the small warming we have experienced will lead to drastic increases in global temperature.
Worm greenhouse emissions (primarily methane)
from our global ocean sediment buddies could lead to that proverbial tipping point - initiating a
runaway global warming and catastrophic
climate change scenario.
