Evidence for regional warmth during medieval times can be found in a diverse but more limited set of records including ice cores, tree rings, marine sediments, and historical sources from Europe and Asia, but the exact timing and duration of warm periods may have varied from region to region, and the magnitude and geographic extent of the warmth are uncertain.

Other factors contributing to the recent regional rapid warming over the Antarctic Peninsula include decreased sea ice in the Bellingshausen Sea, resulting in warmer air temperatures, and decreasing precipitation over the south western peninsula [10, 11].

Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).

Taken together, these initiatives to combat global warming now cover areas that include half the U.S. population, and state governments are already considering how to harmonize regional trading systems with each other, as well as with the European Union's emissions - trading scheme.

Evidence for regional warmth during medieval times can be found in a diverse but more limited set of records including ice cores, tree rings, marine sediments, and historical sources from Europe and Asia, but the exact timing and duration of warm periods may have varied from region to region, and the magnitude and geographic extent of the warmth are uncertain.

Just as importantly, he says, the model helps to explain regional trends that seem to defy the global warming hiatus, including record - breaking heat in the United States last year, and the continued decline of Arctic sea ice.

Yet, we explained there is also reasonable basis for concern that a warming world may at least temporarily increase tornado damage including the fact that oceans are now warmer, and regional ocean circulation cycles such as La Nina / El Nino patterns in the Pacific which affect upper atmospheric conditions appear to becoming more chaotic under the influence of climate change.

We also know that in a warming world we have more water vapor in the atmosphere and some regional water bodies including the Gulf Of Mexico are warmer now then in recent times most likely under the influences of climate change.

Theses lines of evidence include: — Post-1950s stratospheric cooling — Post-1950s mesospheric cooling — Post-1950s thermospheric cooling — Horizontal / regional distribution of warming and the temporal pattern of warming [DOI: 10.1175 / BAMS - D -11-00191.1, pages 1683 and 1684]-- Exclusion of other likely causal factors, such as the Sun [ex: solar - induced warming causes warming of the stratosphere, mesosphere, and thermosphere, yet scientists observed cooling in these layers].

In response to Pounds» link to global warming they wrote, «Numerous other variables, including regional banana and beer production, were better predictors of these extinctions.

Many agricultural regions warm at a rate that is faster than the global mean surface temperature (including oceans) but slower than the mean land surface temperature, leading to regional warming that exceeds 0.5 °C between the +1.5 and +2.0 °C Worlds.

-- Not later than 18 months after the date of enactment of this section, the Administrator, taking into consideration the public health and environmental impacts of black carbon emissions, including the effects on global and regional warming, the Arctic, and other snow and ice - covered surfaces, shall propose regulations under the existing authorities of this Act to reduce emissions of black carbon or propose a finding that existing regulations promulgated pursuant to this Act adequately regulate black carbon emissions.

As the global climate warms, at - risk communities need to improve governance of wildfire issues, including landscape management, while also strengthening regional and international measures for cooperation, Goldammer tells Pacific Standard.

This is known via various lines of evidence, including: — Post-1950s stratospheric cooling — Post-1950s mesospheric cooling — Post-1950s thermospheric cooling — Horizontal / regional distribution of warming and the temporal pattern of warming [DOI: 10.1175 / BAMS - D -11-00191.1, pages 1683 and 1684]-- Exclusion of other likely causal factors, such as the Sun [ex: solar - induced warming causes warming of the stratosphere, mesosphere, and thermosphere, yet scientists observed cooling in these layers].

Though there can be significant differences in regional surface impacts between one SSW event and another, the typical pattern includes changes in sea level pressure resembling the negative phase of the North Atlantic Oscillation (NAO) / Arctic Oscillation (AO), (representing a southward shift in the Atlantic storm track), wetter than average conditions for much of Europe, cold air outbreaks throughout the mid-latitudes, and warmer than average conditions in eastern Canada and subtropical Asia (see figure below, left panel).

Other factors, including greenhouse gases, also contributed to the warming and regional factors played a significant role in increasing temperatures in some regions, most notably changes in ocean currents which led to warmer - than - average sea temperatures in the North Atlantic.

On a regional scale, paleoclimatic data indicate that similar to the instrumental period, warm and dry spells often concur in the Southwest, including during this period (13).

In other words, trends and / or variability in larger - scale features of the climate (including rising temperature from global warming) are not very strongly (if at all) related to regional and temporal characteristics of streamflows across the U.S.
