Many people could face unbearable temperatures soon.  Temperature anomalies on land in the Northern Hemisphere (red) are spread out much wider and they are more than 0.5°C higher than global land+ocean anomalies (blue). The pale green and grey trends are both long-term trends based on January 1880-August 2020 NOAA data. The short-term red and blue trends, based on January 2013-August 2020 NOAA data, are added to show the potential for a rapid rise. How could temperatures possibly rise this fast?  A rapid temperature rise could eventuate by 2026 due to a number of contributing factors: • crossing of the latent heat and methane tipping points • moving toward an El Niño  • entering solar cycle 25 • changes in aerosols • feedbacks kicking in more strongly as further tipping points get crossed. Crossing the Latent Heat and Methane Hydrate Tipping Points The image below, updated from an earlier post , shows two such tipping points. The August 2020 ocean temperature anomaly on t...

The unthinkable consequences of global warming by Andrew Glikson “We’re simply talking about the very life support system of this planet”. Hans Joachim Schellnhuber 2009. “Burning all fossil fuels would create a different planet than the one that humanity knows. The paleoclimate record and ongoing climate change make it clear that the climate system would be pushed beyond tipping points, setting in motion irreversible changes, including ice sheet disintegration with a continually adjusting shoreline, extermination of a substantial fraction of species on the planet, and increasingly devastating regional climate extremes” and “this equates to 400,000 Hiroshima atomic bombs per day 365 days per year ” James Hansen et al. 2012 . Humanity is fast reaching our moment of truth. What Hansen, Schellnhuber and others have warned us is based on evidence consistent with the basic laws of science, the discipline which, contrary to medieval superstition, is founded on direct observations, calculat...

Above image depicts how humans could go extinct within years. The image was created with NASA LOTI 1880-Dec.2019 data, 0.78°C adjusted to reflect ocean air temperatures (as opposed to sea surface temperatures), to reflect higher polar temperature anomalies (as opposed to leaving out 'missing' data) and to reflect a 1750 baseline (as opposed to a 1951-1980 baseline), with two trends added. Blue: a long-term trend based on Jan.1880-Dec.2019 data. Red: a short-term trend, based on Jan.2009-Dec.2019 data, to illustrate El Niño/La Niña variability and how El Niño could be the catalyst to trigger huge methane releases from the Arctic Ocean. This updates an earlier post with more detail on how the image was created. The image below shows El Niño/La Niña variability going back to 1950 , added to the NOAA monthly temperature anomaly.

Above image depicts how humans could go extinct as early as 2020. The image was created with NASA LOTI 1880-Nov.2019 data, 0.78°C adjusted to reflect ocean air temperatures (as opposed to sea surface temperatures), to reflect higher polar temperature anomalies (as opposed to leaving out 'missing' data) and to reflect a 1750 baseline (as opposed to a 1951-1980 baseline), with two trends added. Blue: a long-term trend based on Jan.1880-Nov.2019 data. Red: a short-term trend, based on Jan.2009-Nov.2019 data, to illustrate El Niño/La Niña variability and how El Niño could be the catalyst to trigger huge methane releases from the Arctic Ocean. How was above image created? Let's first look at the baseline. The NASA default baseline is 1951-1980. The added trend in the image below shows early 1900s data to be well below this 1951-1980 baseline. In this analysis, a 0.28°C adjustment was therefore used to reflect this, and to reflect a 1750 baseline, a further 0.3°C was used, adding...
