But here's your question: why we should be concerned even with the global temperature

due to co2 we are already living in a greenhouse.Whatever one does in that greenhouse will remain in the greenhouse.INDUSTRIOUS HEAT will remain in the greenhouse instead of escaping into outer space; this is a far greater contributor to global warming than other factors and far more difficult to reduce without reducing economic activity.Like warm moist air from your mouth on cold mornings so melting antarctic
ice will turn into cloud as it meets warm moist air from tropics the seas will not
rise as antarctica is a huge cloud generator.A thick band of cloud
around the earth will produce even temps accross the whole earth causing the wind to moderate even stop.WE should be preparing for this possible scenario»
These wildfires release soot into the atmosphere, which accelerates the rate of melting of glaciers, snow and
ice it lands upon, which can lead to less reflectivity, meaning more of the sun's heat is absorbed, leading to more global warming, which leads to even more wildfires, not to mention greater sea level
rise, which is already threatening coastal areas
around the world.

Unless we get CO2 back below 275ppm the
ice is going to continue to melt and we are going to get +80 metres of
rise, and most of the good infrastructure works in coastal cities
around the world are merely serving to enhance the dive experience for future tour - boat operators.
What this argument fails to consider is that the greater SST also produces a more vigorous updraft, so that the
rising moist air has less time in which the collision / coalescence process can work before the air reaches the upper cloud layers where spontaneous
ice nucleation takes place (at somewhere
around -40 C, reached near the top of the troposphere).

RISING FAST, NEW STUDIES FIND Melting
ice could raise levels up to 3 feet by 2100, scientists say David Perlman, Chronicle Science Editor Friday, March 24, 2006 Glaciers and

around the world to
rise as much as three feet by the end of this century and 13 to 20 feet in coming centuries, scientists are reporting today.
To get a sense of how the views of Arctic experts have coalesced
around a

If all of the currently available carbon resources — estimated to be

rose by
around 3 - 8C, causing the

«At the end of the last
ice age
around 11,000 years ago, the
ice sheet went through a period of rapid, sustained

rising sea levels pushed warm water closer to the
ice sheet — just as is happening today,» NASA said.
The most recent
ice core reading,
around 2000 years ago, was 287 ppmv, so that 10 %

Besides these thousands of thermometer readings from weather stations
around the world, there are many other clear indicators of global warming such as
rising ocean temperatures, sea level, and atmospheric humidity, and declining snow cover, glacier mass, and sea
ice.
Consistent with the aforementioned sea level
rise acceleration, a number of articles have projected global sea level
rise of
around 1m or more by 2100, based on past estimates of sea level
rise (in response to warming) and based on melting of land
ice (with thermal expansion):
In that scenario, Greenland's
ice cap will likely collapse, and the resulting sea - level
rise will wash away any low - lying island nations that are still
around.
Anyway, today we try to explain the exact opposite: how northern hemisphere
ice ages can quite suddenly weaken — at least in case of the last one, which had its cold peak
around 18,000 years ago, after which atmospheric CO2 levels «suddenly» (over a millennium or so)
rose by 30 per cent, and temperatures started to climb closer * to our current Holocene values.
As temperatures
rise around the world, one of the obvious consequences is the melting of
ice on Earth, which in turn causes water levels in the world's oceans and seas to
rise.
Yet some kind of climate model is indispensable to make future predictions of the climate system and IPCC has identified several reasons for respect in the climate models including the fact that models are getting better in predicting what monitoring evidence is actually observing
around the world in regard to temperature,
ice and snow cover, droughts and floods, and sea level
rise among other things.
