Sentences with phrase «rapid regional warming»

At that point in geological history, global surface temperatures were rising naturally with spurts of rapid regional warming in areas like the North Atlantic Ocean.

However, Petrenko found that the gradual, natural global warming and rapid regional warming that characterized the deglaciation 12,000 years ago — events that were in some aspects comparable to the current human - driven global warming — did not trigger detectable releases of methane from these reservoirs.

But with climate change, the WAP is experiencing rapid regional warming, with fewer days each year of fast ice — letting the icebergs into the shallows more often, where they carve huge gashes through the habitat of the colorful, tentacled invertebrate animals carpeting the sea floor.

Not exact matches

In this new regime, with a complete absence of sea ice and snow in the Northern Hemisphere, with rapid warming of the arctic region due to increased solar absorption, a jump in regional temps will occur.

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].

The impacts of this recent regional rapid warming around the Antarctic Peninsula have been dramatic, with the collapse of ice shelves [14], and with 87 % of glaciers in recession [15].

Three areas in particular have been subject to recent regional rapid warming (sensu Vaughan et al., 2003), with rates of warming far faster than the average noted in the IPCC.

Although globally averaged annual temperatures warmed about 1 deg F since the early 1900s (viewed as rapid by paleoclimatologists and geologists), regional climate station annual temperatures in northern Minnesota show warming by several degrees F since the early 1900s.

Under the right circumstances glaciers melt abruptly, regional forests and soil become carbon emitters abruptly, and oceanic / atmospheric currents shift abruptly, leading to rapid global warming.

The point I am trying to make is «when it is claimed that DO events represent a much larger and more rapid climate change than anthropogenic global warming,» perhaps DO events do cause rapid regional climate change larger and more rapid than anthropogenic global warming generally.

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).

I haven't thought much about the THC although I've expressed doubt about seeing large regional cooling if it did shut down or change direction, mainly because global warming is so rapid that any cooling effect with time would be dampened by warming factors going on.

A (2) Modern warming, glacier and sea ice recession, sea level rise, drought and hurricane intensities... are all occurring at unprecedentedly high and rapid rates, and the effects are globally synchronous (not just regional)... and thus dangerous consequences to the global biosphere and human civilizations loom in the near future as a consequence of anthropogenic influences.

There must have been brief periods of very rapid temperature change mixed in there (certainly on the regional level) in addition to slower - warming periods, and I'm under the impression other data (such as Greenland ice cores and deep - sea cores) support that scenario as well.

«What we're seeing is stark evidence that the gradual temperature increase is not the important story related to climate change; it's the rapid regional changes and increased frequency of extreme weather that global warming is causing.
