Alternatively, it may be an important warming mechanism that limits the minimum temperature of cold surfaces.

In the current context of global warming it is important to assess the impacts that changes in ocean and climate may have on Antarctica, and reconstructing past climate fluctuations provides vital information on the responses and possible feedback mechanisms within the climate system.

BACK TO TOPIC: If CO2 & CH4 are important forcings in a linear GW scenario, then in a «runaway» GW scenario of the warming triggering further mechanisms of warming, triggering further mechanisms, our anthropogenic GHG emissions have even more ultimate impact.

With the IPCC previously «taking a pass», in its assessment of Greenland's contribution to sea - level rise - due to poor understanding of how ice sheets would respond to global warming back in 2007 - this new paper is an important first stab at pinning down the slippery mechanisms of «ice sheet dynamics».

In so far as those on the political left and right understand to some extent that human expansion is destroying the biosphere — they know about global warming — it would appear that compartmentalization is among the most important pyschological defense mechanisms.

The Talanoa dialogue, an important outcome from this COP, switches on the ambition ratchet mechanism of the Paris Agreement and sets into motion the climate pact that governments promised to abide by two years ago to keep warming below 1.5 °C.

Previous large natural oscillations are important to examine: however, 1) our data isn't as good with regards to external forcings or to historical temperatures, making attribution more difficult, 2) to the extent that we have solar and volcanic data, and paleoclimate temperature records, they are indeed fairly consistent with each other within their respective uncertainties, and 3) most mechanisms of internal variability would have different fingerprints: eg, shifting of warmth from the oceans to the atmosphere (but we see warming in both), or simultaneous warming of the troposphere and stratosphere, or shifts in global temperature associated with major ocean current shifts which for the most part haven't been seen.

E.g., research assumes greenhouse gas emissions cause warming without explicitly stating humans are the cause»... carbon sequestration in soil is important for mitigating global climate change» (4a) No position Does not address or mention the cause of global warming (4b) Uncertain Expresses position that human's role on recent global warming is uncertain / undefined «While the extent of human - induced global warming is inconclusive...» (5) Implicit rejection Implies humans have had a minimal impact on global warming without saying so explicitly E.g., proposing a natural mechanism is the main cause of global warming»... anywhere from a major portion to all of the warming of the 20th century could plausibly result from natural causes according to these results» (6) Explicit rejection without quantification Explicitly minimizes or rejects that humans are causing global warming»... the global temperature record provides little support for the catastrophic view of the greenhouse effect» (7) Explicit rejection with quantification Explicitly states that humans are causing less than half of global warming «The human contribution to the CO2 content in the atmosphere and the increase in temperature is negligible in comparison with other sources of carbon dioxide emission»»

But the lack of statistically significant results and, more important, the absence of evidence pointing to a smoking gun — a physical mechanism in the climate system that ties Arctic changes to extreme events — has left many top climate researchers unconvinced that rapid Arctic warming is a major player in causing extreme weather events outside of the Arctic itself.
