This too supports this hypothesis
since the greater difficulty in forming cores without the presence of
ice would hamper the formation of large
planets.

planet as a whole has warmed about 1.3 °F

The
planet as a whole has heated up by about 1.3 °F
since 1900, but on the peninsula, it has shot up by a whopping 5 ° in just 50 years, forcing massive
ice shelves to disintegrate and penguin colonies to collapse.
On December 1, 2009, two astronomers submitted a pre-print suggesting that the
planet's extreme axial tilt (an obliquity of 97 degrees) may have resulted from the presence of a large moon that has
since been ejected from orbit around the
ice giant by the pull of another
planet during the orbital migration of the giant
planets early in the formation of the Solar System.
After the Rebellion?s defeat on the
ice planet Hoth, Luke journeys to the
planet Dagobah to train with Jedi Master Yoda, who has lived in hiding
since
[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in equilibrium with water /
ice, would precipitate out if not for the CO2, so acts as a feedback;
since the oceans cover so much of the
planet, water is a large positive feedback; melting snow and
ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)
I am saying that increased CO2 is responsible for the melting the Arctic sea
ice which will be catatrophic,
since the sea
ice acts as the air conditioning unit for the
planet.
Ever
since the
planet descended into a cycle of
ice ages and warm intervals 2 million years ago, glaciers have surged and ebbed like a slow, cold tide.
The
planet has warmed up
since the Little
Ice Age and it has warmed up relatively quickly between 1975 and 1998, so much so that we humans are becoming consumed with guilt and anxiety about our place on Earth.
Also note that the
planet has warmed
since about 1850, the end of the Little
Ice Age.
Since the end of the Little
Ice Age in the 1880s, the
planet has warmed by about 0.8 degrees C.
A few hours ago you were saying: The answer is pretty straightforward: the
planet has been warming
since the last great
Ice Age, and the subsequent LIA.
As a whole, the
planet has been shedding sea
ice at an average annual rate of 13,500 square miles (35,000 square kilometers)
since 1979, the equivalent of losing an area of sea
ice larger than the state of Maryland every year.»
If you are concerned about planetary climate, then it behooves you to consider the «history» of the
planet before singling out something as paltry as the warming
since the end of the Little
Ice Age.
Since then the
planet has been clawing its way out of the Little
Ice Age during a period of gentle global warming.
[22]
Since 1860, the
planet has been recovering from the Little
Ice Age (1300 — 1850) and has gradually warmed.
By «global warming» these papers don't, of course, mean the mild warming of around 0.8 degrees Celsius that the
planet has experienced

By comparing the atmospheric CO2 increase (note that
since CO2 is well - mixed in the atmosphere, a single
ice core record can be used as an accurate representation for CO2 - Shakun et al. used the Antarctic EPICA Dome C
ice core for CO2 data) to these many different temperature records, Shakun et al. are able to discern whether the CO2 increase led or lagged temperature changes in various different geographic locations, and for the
planet as a whole.
In its first comprehensive report
