So with that simple first step, we know that the “average” world temperature for June 2018 was +0.21 deg C above the 1981 – 2010 mean. That represented adeclineof about 0.65 deg C from the all time high of this 39-year record, which was reached in early 2016. The 0.65 deg C de...
The 2012 International Energy Agency’sWorld Energy Outlookclearly rang the alarm bells that current world energy policies are inexorably leading the earth to a rise in mean surface temperature of 3.6C, that is, well above the 2C that the IPCC recommends as the safe limit. Energy efficiency w...
The Assessment Reports of the IPCC, for example, calculate that, if the atmosphere is to stay within its current dynamic equilibrium, a concentration of CO2 somewhere between 350 and 450 ppm is all that the natural cycle of CO2 transformation can take. If we exceed this amount, all the ...
Below, we'll try to understand where this number comes from, why it is uncertain (at least for IPCC climatologists who rely on global circulation models) and what we can do about it. The sensitivity of a Black Body Earth Let us try to estimate the sensitivity of a Black Body Earth. ...
creations of the universe. The Big Bang theory is assumption ——- universe was created from a point where the density were very enormous thus we can’t think, the law of physics do not agree this matter and if so, what was before the Big Bang & what was the conditions of the same?
The IPCC also puts it at over 90% that the changes in both CO2 levels and temperature are caused by human activity (which is kind of like saying there’s over a 90% chance that a rain storm has been caused by cloud activity). Now the question becomes—how much does the temperature ne...
And, yes, this effect is included in the climate models used by the IPCC. It would have to be, otherwise the average temperature distributions in those models would be wildly wrong: much too warm in the lower troposphere, and much too cold in the upper troposphere. ...
He said that “The green movement must become a mass movement in green consumption.” In order to achieve this goal Leahy argued that “we must empower everyone – not just the enlightened or the affluent.” He believed that the market was ready for this green consumer “revolution,” and ...
Part of the emphasis on (in)validating model predictions was the IPCC, which in the 4th AR, boldly prognosticated: “A temperature rise of about 0.2 °C per decade is projected for the next two decades for all SRES scenarios.” Not sure if this was addressed or ignored in the 5th ...
