The image below, adapted from Climate Reanalyzer, shows the temperature in the year 2100, in a CMIP6 SSP585 scenario. The image shows how much the temperature will have risen in 2100, at 2 meters above the surface and compared to the period 1979-2000.  The image below shows a progressive temperature rise reaching 4.589°C in 2100 compared to the same period, i.e. 1979-2000 and in a CMIP6 SSP585 scenario.  The 1979-2000 period is relatively recent. The temperature has been rising for longer than that. The image below shows a progressive temperature rise reaching 4.91°C by 2100 in ..read more

The temperature in the Tropics (23.5°S-23.5°N, 0-360°E) reached a new record high on April 24, 2024 of 27°C (or 80.6°F).  The image below shows the monthly temperature anomaly over the past few years through March 2024, when the anomaly reached a record high of 1.448°C (or 2.606°F).   Note that the anomaly in the top image is calculated from 1979-2000 as a base, while anomalies in the above image are calculated from 1951-1980 as a base. When calculated from a pre-industrial base, these anomalies will be much higher. The high temperatures are causing widespread dama ..read more

The image below indicates that Arctic sea ice volume has meanwhile passed its annual maximum. Over the coming months, volume can be expected to decrease rapidly. The image also highlights that, over the past few months, Arctic sea ice volume has been the lowest on record for the time of year. The image below illustrates the decline of Arctic sea ice volume over the years. The image also confirms that the annual maximum volume was recently reached and that it was the lowest maximum for the 24 years on record.  Given that Arctic sea ice currently is still relatively extensive, this rec ..read more

The temperature in the Tropics (23.5°S-23.5°N, 0-360°E) reached a new record high on April 23, 2024 of 26.925°C (or 80.47°F).  The image below shows the monthly temperature anomaly over the past few years through March 2024, when the anomaly reached a record high of 1.448°C (or 2.606°F).   Note that anomalies in the above image are calculated from 1951-1980 as a base. When calculated from a pre-industrial base, anomalies will be much higher. The high temperatures are causing widespread damage and are threatening to cause huge loss of life of people, livestock and w ..read more

By Andrew Glikson “History is a nightmare from which I am trying to wake” (James Joyce) Figure 1. Extinctions CC from: The five mass extinctions in Earth History. The rate of the current rise of greenhouse gas levels and thereby temperatures is higher by more than an order of magnitude than that of previous mass extinctions. (Figures 11.2, 11.5). Glikson. A.Y., 2023 The Trials of Gaia. War ─ the mass sacrifice of young generations throughout history, culminating in the barbarism of empires such as the Roman “Pax Romana”, represents the repeated collapse of sanity with transi ..read more

The temperature in the Tropics (23.5°S-23.5°N, 0-360°E) reached a new record high on April 20, 2024 of 26.913°C (or 80.44°F).  The image below shows the monthly temperature anomaly over the past few years through March 2024, when the anomaly reached a record high of 1.448°C (or 2.606°F).   Note that anomalies in the above image are calculated from 1951-1980 as a base. When calculated from a pre-industrial base, anomalies will be much higher. The rise in temperature threatens to cause widespread loss of life of people, livestock and wildlife, crop failure and ecosys ..read more

The North Atlantic Ocean is heating up, as more sunlight starts reaching the Northern Hemisphere. The above image, adapted from Climate Reanalyzer, shows sea surface temperatures up to April 11, 2024. The image shows that 2024 temperatures have been significantly higher than 2023 temperatures for the same date. The annual maximum temperature in 2023 was reached on August 31. Temperatures can be expected to rise dramatically over the next few months, in line with the change in seasons.  2024 temperatures to exceed 2023 temperatures? The image below, adapted from NOAA, shows global ocean ..read more

The MADNESS of NUCLEAR and CLIMATE HORROR by Andrew Glikson The 24-hour media news cycle clouds the minds of people, perpetrators and hapless victims alike, to the future dimension, whether that of future generations or of the natural world itself. During the 20-21ˢᵗ centuries, as mean global temperature keeps rising toward 4°C, a failed brain neuron or a damaged computer chip can trigger a nuclear catastrophe, while the 24-hour media news cycle can blind humanity to the future. The conditions emerge where the world is largely taken over by the banality of evil, insane mass murders ..read more

[ click on images to enlarge ] The above image shows monthly Atlantic surface temperatures through February 2024 (background image), highlighting the potential for the slowing down of the Atlantic meridional overturning circulation (AMOC) to contribute to more heat accumulating at the surface of the Atlantic and methane to erupt from the seafloor of the Arctic Ocean. As temperatures rise, feedbacks are kickong in with greater ferocity, resulting in creased ocean stratification, less reflectivity, heavier melting of Greenland's ice and freshwater runoff from land and rivers, all of ..read more

On March 15, 2024, the daily average carbon dioxide (CO₂) at Mauna Loa, Hawaii, was 427.93 parts per million (ppm), as illustrated by the image below, adapted from NOAA.  This is the highest daily in situ average in the NOAA record at Mauna Loa, which is the more remarkable since the annual CO₂ maximum is typically reached in May, so even higher values are likely to be reached over the next few months. The image below, adapted from NOAA, shows CO₂ for the last 31 days at Mauna Loa.  The image below, adapted from the Scripps Institution of Oceanography, shows that CO₂ at Mauna Loa w ..read more
