Sentences with phrase «globally averaged temperature changes»
In order to estimate globally averaged temperature changes with a high degree of accuracy, it is necessary to have a broad spatial distribution of observations that are made with high precision.break

On the other hand, the Arctic sea ice albedo reduction does contribute significantly to polar amplification of globally averaged temperature changes.
... Polar amplification explains in part why Greenland Ice Sheet and the West Antarctic Ice Sheet appear to be highly sensitive to relatively small increases in CO2 concentration and global mean temperature... Polar amplification occurs if the magnitude of zonally averaged surface temperature change at high latitudes exceeds the globally averaged temperature change, in response to climate forcings and on time scales greater than the annual cycle.
Not exact matches
In fact, all climate models do predict that the change in globally - averaged steady state temperature, at least, is almost exactly proportional to the change in net radiative forcing, indicating a near - linear response of the climate, at least on the broadest scales.
Except that GHG forcing + cooling aerosol forcing results in less precipitation globally in general than reduced GHG forcing that produces the same global average temperature, as found in «Climate Change Methadone» elsewhere at RC.
That we can get a 10 - or even 15 - year period with no real change in globally averaged temperature even though in the end we have strong global warming.
The crux of Bates» claim is that NOAA, the federal government's top agency in charge of climate science, published a poorly - researched but widely praised study with the political goal of disproving the controversial global warming hiatus theory, which suggests that global warming slowed down from 1998 until 2012 with little change in globally - averaged surface temperatures — a direct contrast to global warming advocates» claim that the earth's temperature has been constantly increasing.
Antarctic temperature changes across the ice ages were very similar to globally - averaged temperatures, except that ice age temperature changes over Antarctica were roughly twice that of the global average.
Consider that the measurement used, the globally averaged temperature anomaly (GATA), is always changing.
The air responds to a change in it's own resistor efficiency by changing it's own circulation patterns to again meet the requirement that the surface air temperature and the sea surface temperature be the same on average globally.
Dr. Gerald A. Meehl — Nature Climate Change — 18th September 2011 «There have been decades, such as 2000 — 2009, when the observed globally averaged surface - temperature time series shows little increase or even a slightly negative trend1 (a hiatus period)....»
Doing this on a year - to - year basis shows NO apparent correlation with the absolute «globally and annually averaged land and sea surface temperature anomaly» (i.e. HadCRUT3), but does show a weak correlation with the CHANGE in temperature from the previous year, for example:
3) So in the last 100 years, the Sun had zero impact on the change of globally averaged temperatures?
These feedbacks are the primary source of uncertainty in how much the earth will warm (side note: the question that most climate scientists who study the forcing due to CO2 try to answer is, how much will the long - term globally averaged surface temperature of the earth rise due to an rapid rise of CO2 to twice its industrial level, that is, 270 ppm to 540 ppm; it is currently about 380 last time I checked, and rising at ~ 3ppm / year, although this rate of change appears to be accelerating).
Globally, at the United Nations Conference on Climate Change in Paris, 195 countries — including the United States, at the time — agreed to pollution - cutting provisions with a goal of preventing the average global temperature from rising more than 1.5 degrees Celsius above preindustrial times.
Recently, under the Paris Agreement on Climate Change, there has been a call for research into impacts associated with a 1.5 C or 2C globally - averaged surface temperature anomaly.
