Sentences with phrase «significant regional warming»

Not exact matches

The researchers detected a «significant regional flux» of methane, a greenhouse gas with about 30 times the warming potential of carbon dioxide over a 100 - year period, coming from an area of gas wells in southwestern Pennsylvania.

In fact previous climate warming after the last ice age did have significant negative impacts on early human settlements (evidence of periods of significant and rapid regional sea level rise).

Finally, while economics may be critical to your definition of «catastrophic» anthropogenic global warming, economics says nothing about the science underlying the projections of sea level rise, the physics of Arctic amplification, changes to albedo that lead to greater warming that may lead to significant releases of methane clathrate deposits, regional projections of reduce (or enhanced) precipitation, and so on.

While most people now understand that the enhanced greenhouse effect means a much warmer planet, communicating regional shifts in weather remains a significant challenge.

At any point in time, at anyplace on the globe, there could be significant warming, while significant cooling is simultaneously happening at another locale, and both can be associated with vast regional areas of insignificant temperature change.

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.

[8] Liz Thomson et al 2009 Ice core evidence for significant 100 - year regional warming on the Antarctic Peninsula GEOPHYSICAL RESEARCH LETTERS, VOL.

I'm alternately told by «skeptics» (1) it's regional impact that's important, (2) it's global data that's more important, (3) there is no such thing as «global temperatures,» (4) «skeptics» are not monolithic, (5) «skeptics» don't doubt that global temperatures are warming (and that it is to some extent influenced by AC02), or alternately «we dismiss non-Global data), (6) all methodologyies used to determine global temps are unreliable, (7) global warming has stopped, (8) we're experiencing global cooling, (9) what matters is long term trends, (10) short - term trends are significant, (11) what's happening in Arctic isn't important (because it's regional), (12) what's happening in the Antarctic is important (despite it being regional).

Since the NH experienced a MWP that was «not significant» because it was «regional» and it appears we are having another «not significant» regional warm period, you would need to ask the people that decided that the MWP was «not significant».

They found that global temperatures fluctuated in specific regional patterns but that all regions except Antarctica saw a long - term cooling trend followed by significant warming in the past 30 years.

While surface temperature show a significant warming over western Himalayas in the last few decades, the observed regional precipitation changes are irregular and not spatially coherent.

Current warming is so fast that reconstructions are pushed to their limits... what?!?!? And this supposed unprecedented warming wasn't significant locally / regionally from 1980 - end of 2004, at least not enough to be captured by proxies... but, of course, operate under the assumption that all warming in the past was significant at the local / regional level and therefore captured by the proxies.

The scientific evidence is unequivocal: There exist huge regional climate swaths of the globe that have mildly warmed in an unexceptional manner during the modern industrial / consumer era; and there exist multiple large areas that even lack any regional climate - significant modern warming whatsoever.
