I guess it's better to burn it and turn it into CO2 than to just lets it escape to the atmosphere because of
rising polar temperatures.
If recent trends continue, the Arctic will be ice - free on January 30, 2018 at 6:04 AM,
with polar temperatures averaging -31 C. Ocean and Ice Services Danmarks Meteorologiske Institut
Ice core data also indicate that
average polar temperatures at that time were 3 °C to 5 °C warmer than the 20th century because of differences in the Earth's orbit.
«Furthermore, the models predict that
polar temperature trends should greatly exceed the tropical values — and they clearly don't... In fact, the Antarctic has been cooling,» adds Singer.
One shows a nonlinear transition to a new stable state in < 10 years
when polar temperature rises above − 5 °C (13 °C above present), whereas the other shows a more linear transition.
Rising
polar temperatures caused the average thickness of winter Arctic sea ice to decrease from about 12 feet to 6 feet between 1978 and 2008, and thinner ice melts more readily.
Charon's winters are cold, with
polar temperatures only a few degrees higher than absolute zero (minus 459.67 degrees Fahrenheit, or minus 273.15 degrees Celsius) at coldest.
Lunar Reconnaissance Orbiter sensor detects
south polar temperature differences during the day (left) and at night where some areas were found to be nearly -400 F below zero — colder than measured so far on Pluto.
Speaking of
polar temperature changes (this is my lame attempt at looking like I'm staying on thread), does anyone here have some expertise they can share regarding the potential (or lack thereof) for tropospheric impact resulting from the ongoing sudden stratospheric warming event in the Arctic?
There has to be an obvious and simple flaw in the using of lower troposphere satellite temperatures at 3,000 m elevation to guesstimate actual
surface polar temperatures.
In the hothouse conditions of the mid-Cretaceous (80 - 100 My), tropical temperatures are thought to have increased relatively little (there is dispute about how much),
while polar temperatures increased by a huge amount (maybe 20 °C).
It looks to me like he has based his blackbody analysis on maximum equatorial temperatures and
minimum polar temperatures on the Moon and then compared them to temperatures actually measured at the landing sites.
While North America freezes under
record polar temperatures, the southern hemisphere is experiencing the opposite extreme as heat records are being set in Australia after the hottest year ever.
«Furthermore, the models predict that
polar temperature trends should greatly exceed the tropical values — and they clearly don't... In fact, the Antarctic has been cooling,» adds Singer.
However, palaeoclimatic evidence (Denman et al., 2007 Sections 6.4.3.2 and 6.4.3.3; Overpeck et al., 2006; Otto - Bliesner et al., 2006) suggests that Greenland and possibly the WAIS contributed to a sea - level rise of 4 - 6 m during the last interglacial,
when polar temperatures were 3 - 5 °C warmer, and the global mean was not notably warmer, than at present (Meehl et al., 2007 Sections 10.7.4.3 and 10.7.4.4).
My intuition is that the abnormal warming of the poles will continue, so a 5C rise in global temperature would mean perhaps a 15C rise
in polar temperatures, and that should be able to melt Greenland in short order.
«The Earth's tilt contributes to
a polar temperature gradient,» said Li.
During the LIG,
polar temperatures were comparable to those expected to accompany 1 - 2 °C above pre-Industrial levels of future global warming.
Despite how hard I try, I must say, it's THE warmest coat you could wear in
the polar temperatures to come.
The polar temperature will be... Continue reading →
Severe «snowmageddon» winters are very likely linked to the rapidly increasing
polar temperatures, with deadly summer heatwaves and intense flooding probably also linked.
Are
polar temperatures increasing?
In fact, the «fact» that
polar temperatures have been increasing faster than in the rest of the world was the prime «fact» presented by Oreskes in her influential lecture, The American Denial of Global Warming, to justify her thesis that the whole issue of global warming and what we should do about it was done and dusted in the 1970s.
Kump and David Pollard, senior research associate, Earth and Environmental Systems Institute, looked for another way to create a world where mean annual temperatures in the tropics were above 100 degrees Fahrenheit and
polar temperatures were in the 50 - degree Fahrenheit range.
In IPCC projections with ocean - atmosphere general circulation models (OAGCMs)(12), half of the models become ice - free in September during this century (19), at
a polar temperature of − 9 °C (9 °C above present)(20).
