Taking into account all 20 models, the spread of results reduces when the scientists looked at the rainfall changes
per degree of global warming independent of the exact time path of the warming.
This relationship of CO2 to warming is usually called sensitivity, and is often expressed as the number
of degrees of global warming that would result from a doubling in global CO2 concentrations.
The study, published in Nature Climate Change, suggests that nearly 4 million square kilometres of frozen soil — an area larger than India — could be lost for every
additional degree of global warming experienced.
We don't get any closer to science by denying the significant possibility that we are causing significantly adverse changes in climate than we do by the ridiculous assertion that we understand the chaotic complexity of climate well enough to say with certainty how many parts per millions of carbon dioxide in the atmosphere will lead to how
many degrees of global warming.
The study, conducted by climate change experts from the universities of Leeds and Exeter and the Met Office, all in the UK, and the universities of Stockholm and Oslo, suggests that nearly four million square kilometres of frozen soil — an area larger than India — could be lost for every
additional degree of global warming the planet experiences.
The latest report is the first to include an assessment of a «carbon budget» — a finite amount of carbon that can be burnt before it becomes unlikely we can avoid more than two
degrees of global warming.
Surprisingly, the NHSM as well as the Hadley and Walker circulations have all shown substantial intensification, with a striking increase of NHSM rainfall by 9.5 % per
degree of global warming.
There was uncertainty about
the degree of global warming, and media - hyped speculation about global cooling confused the public.
This intensification has resulted in significantly greater global summer monsoon rainfall in the Northern Hemisphere than predicted from greenhouse - gas - induced warming alone: namely a 9.5 % increase, compared to the anthropogenic predicted contribution of 2.6 % per
degree of global warming.
Zachriel: There is some uncertainly in climate projections, including
the degree of global warming to expect.

For
every degree of global warming, the forest needs a 15 percent increase in precipitation to compensate for the increased drying caused by warming, according to a recent study.
IPCC computer models dating from 1990 through the present have consistently predicted at least 2.4
degrees of global warming per century.
Katherine Wells pointed out that aiming for 2
degrees of global warming is poor risk management.
You may not notice a fraction of a degree of warming, but you do notice the super hurricane, or super nor'easter, or super cloud burst, or super drought, that a fraction of
a degree of global warming can produce.
New Statement: During the past 9 years most datasets indicate
some degree of global warming taking place.
With one exception (the Maldives), their targets fall far short of the reductions needed to prevent more than two
degrees of global warming.
But the difference between 1.5 and 2
degrees of global warming is a very big deal.
My reading of the new projections suggests that to play its part in preventing two
degrees of global warming, the UK needs to cut greenhouse gases by roughly 25 % from current levels by the end of 2012 — a quarter in four years.
However, current national pledges (known as INDCs) add up to around 3
degrees of global warming and much steeper cuts are required, according to Friends of the Earth Europe.
If a place is ten degrees above normal at a time of one
degree of global warming, it does not make sense to say that one degree is due to climate change, and nine degrees «would have happened anyway», even in a statistical sense.
But we can still determine how high and how fast levels rise by controlling
the degree of global warming that we cause.
Each degree of global warming is likely to raise sea level by more than 2 meters in the future, a study now published in the Proceedings of the National Academy of Sciences shows.
There is the «business as usual» case that assumes 4
degrees of global warming is inevitable, so we should use the cheapest and most plentiful energy sources available regardless of the fact that burning these fuels will raise atmospheric greenhouse gas concentrations 40 percent higher than current levels.
