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.

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 since the middle of the 19th century as the world crawled out of the Little Ice Age.

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.
