The silicate + CO2 - > different silicate + carbonate chemical weathering rate tends to increase with temperature globally, and so is a negative feedback (but is too slow to damp out short term changes)-- but chemical weathering is also affected by vegetation,
land area, and terrain (and minerology, though I'm not sure how much that varies among entire mountain ranges or climate zones)-- ie mountanous
regions which are in the vicinity of a
warm rainy climate are ideal for enhancing chemical weathering (see Appalachians in the Paleozoic, more recently the Himalayas).

This chemical weathering process is too slow to damp out shorter - term fluctuations, and there are some complexities — glaciation can enhance the mechanical erosion that provides surface area for chemical weathering (some of which may be realized after a time delay — ie when the subsequent
warming occurs — dramatically snow in a Snowball Earth scenario, where the frigid conditions essentially shut down all chemical weathering, allowing CO2 to build up to the point where it thaws the equatorial
region, at which point runaway albedo feedback drives the Earth into a carbonic acid sauna, which ends via rapid carbonate rock formation), while lower sea level may increase the oxidation of organic C in sediments but also provide more
land surface for erosion... etc..

Since the whole world does not appear to freeze during a ice age, the must be massive ice making going at the pole driven by heat lifting oceans of water to the sky from the equator where it is pushed by the expanding air and vapor to the poles areas where it returns to the surface and follows cold

warmer expanding ocean air back down to the equatoral
region.

These models predicted that the Northern Hemisphere Polar
region would
warm fastest and first, that the Southern Ocean would draw a greater portion of atmospheric heat into the ocean system, and that
land ice melt near Greenland and West Antarctica would generate cold, fresh water flows into the nearby ocean zones and set off localized cooling.
Polar bears are one of the most sensitive Arctic marine mammals to climate
warming because they spend most of their lives on sea ice.35 Declining sea ice in northern Alaska is associated with smaller bears, probably because of less successful hunting of seals, which are themselves ice - dependent and so are projected to decline with diminishing ice and snow cover.36, 37,38,39 Although bears can give birth to cubs on sea ice, increasing numbers of female bears now come ashore in Alaska in the summer and fall40 and den on
land.41 In Hudson Bay, Canada, the most studied population in the Arctic, sea ice is now absent for three weeks longer than just a few decades ago, resulting in less body fat, reduced survival of both the youngest and oldest bears, 42 and a population now estimated to be in decline43 and projected to be in jeopardy.44 Similar polar bear population declines are projected for the Beaufort Sea
region.45
Not only was the

Over the past 50 million years, earth cooled because the amount of

Focussing first on this period, the performance of the ERA - Interim and six other reanalyses in the Arctic was examined by Lindsay et al. [12] Although the accuracy of reanalyses in the fast

There were very few readings from the Arctic, yet the Arctic is by far the fastest -

In a ground - breaking new paper (Lansner and Pepke Pedersen, 2018) published in the journal Energy and Environment, an analysis of
land surface instrumental records from across the globe's ocean air sheltered (OAS)
regions reveals that, like the proxy evidence presented above, most of the modern era
warming occurred prior to the 1940s, and the there has effectively been no net
warming since then.
The single highest
land surface temperature (LST) recorded in any year, in any
region, occurred there in 2005, when MODIS recorded a temperature of 70.7 °C (159.3 °F)- more than 12 °C (22 °F)
warmer than the official air temperature record from Libya.
Lansner and Pepke Pedersen (2018) point out that, due to the divergent rates of
warming and cooling for
land vs. ocean water, there is a significant difference in the range of temperature for the
regions of the world influenced by their close proximity to oceans and coastal wind currents (ocean air affected, or OAA) and the inland
regions of the world that are unaffected by ocean air effects and coastal wind because they are sheltered by hills and mountains or located in valleys (ocean air sheltered, or OAS).
They indicate that some
regions of the Earth's surface may cool, and others
warm, by amplitudes larger than the net global response, as a result of differences in solar heating of
land and ocean surfaces.
Add at end of line: «In most

Further, there has been an almost worldwide reduction in glacial mass and extent in the 20th century; melting of the Greenland Ice Sheet has recently become apparent; snow cover has decreased in many Northern Hemisphere
regions; sea ice thickness and extent have decreased in the Arctic in all seasons, most dramatically in spring and summer; the oceans are
warming; and sea level is rising due to thermal expansion of the oceans and melting of
land ice
