Sentences with phrase «average global temps over»

I just published a post on my blog about the interaction of CO2 and average global temps over geologic time and it seems that CO2 has had very little effect on those temps.

The obvious e.g. is the two major levels of average global temp over millions of years, at ~ 12 °C and ~ 22 °C — Ice Box and Hot House.

Not exact matches

The jist of this is that we must NOT suddenly switch off carbon / sulphur producing industries over the planet but instead we must first dramatically reduce CO2 emissions from every conceivable source, then gradually tackle coal / fossil fuel sources to smoothly remove the soot from the air to prevent a sudden leap in average global temps which if it is indeed 2.75 C as the UNEP predicts will permanently destroy the climates ability to regulate itself and lead to catastrophic changes on the land and sea.

After that, the hiatus in global average surface temps for well over a decade became widely known.

Add on the normal summer increase (globally) of 27C / 50F and we will have global average summer temps of @ 49C / 122F not just over small isolated areas, but over huge areas / countries / states / counties.

Between 1985 and 2012, CO2 increased from 345 to 395 ppm, and the average global temperature increased by 0.3 — 0.4 deg C. Due to the higher temp, the outgoing radiation from earth increased over a wide spectral range (3 - 50microns).

This makes for slight differences in their global average temps year to year, but they are ALL showing a clear warming trend over many decades.
