by Andrew Glikson But while “leaders” fail to protect the people from global warming and nuclear war, they have succeeded splendidly in hiding the truth through the denial of climate change, accounting tricks and claims of reduction in domestic emissions, while in fact opening new coal mines, oil wells and fracked coal seams, exporting hydrocarbons through the entire global atmosphere. As mean global temperatures, storms and sea level rise keep rising toward uninhabitable conditions in many parts of the world and thousands of nuclear missiles are aimed to be triggered by accident or design is it too early or already too late for Nuremberg-type trials for those responsible for the ongoing greenhouse gas saturation of the atmosphere and the creation of a doomsday machine ? The Nuremberg principles created by the International Law Commission of the United Nations in connection with the Nuremberg Trials of Nazi leaders following World War II , apply critically once again for those...

The Holocene is the geological epoch that started approximately 11,650 years ago. The demarcation point between the Holocene and the preceding Pleistocene is the end of the last Glacial Period, in line with variations in the Earth's orbit.  Anthropocene Instead of going down as would be in line with changes in the Earth's orbit, temperatures and greenhouse gas levels over the past few thousands of years have kept going up as a result of activities by people. In other words, changes in the Earth's orbit were no longer the dominant force causing changes in temperature and greenhouse gas levels, instead, human activities had become more dominant.  Start of the Anthropocene It makes sense to name an epoch after the dominant force shaping its climate. An earlier analysis concludes that, from the year 3480 BC, emissions by people have been higher than the amount it takes to negate the natural trend for the temperature to fall. From 3480 BC, forcing due to activities ...

Antarctic sea ice extent was 1.788 million km² on February 21, 2023, an all-time low in the NSIDC record. Antarctic sea ice area was 1,050,708 km² on February 22, 2023, as illustrated by the Nico Sun image below. This means that a huge amount of heat that was previously reflected back into space by the sea ice is now instead absorbed by the Southern Ocean, in a self-reinforcing feedback loop that results in further sea ice loss, in turn further speeding up the temperature rise and making the weather ever more extreme. Arctic sea ice extent was 14,271,000 km² on February 19, 2023, the third-lowest extent in the NSIDC record for the time of year, as illustrated by the above image. Global sea ice extent reached a record low of 15,500,000 km² on February 11, 2023, as illustrated by the above image. The situation is dire The dire situation is further illustrated by the image below, showing high sea surface temperature anomalies (from 1...

NOAA data  show a carbon dioxide level of 421.13 parts per million (ppm) for the week starting May 8, 2022, a new record high since measurements started at Mauna Loa, Hawaii. As the image below also shows, very high daily levels were reached recently, as high as 422.04 ppm.  Greenhouse gas levels are even higher further north. Very high carbon dioxide levels were recorded recently at Barrow, Alaska, approaching 430 ppm.  Furthermore, very high methane levels were recorded recently at Barrow, Alaska, including many at levels well over 2000 parts per billion (ppb). The trigger: El Niño and sunspots El Niños typically occur every 3 to 5 years, according to  NOAA  and as illustrated by the NOAA image below, so the upcoming El Niño can be expected to occur within the next few years.  As also illustrated by the  NOAA image  on the right, we are currently in the depths of a persistent La Niña and this suppresses current temperatures. A huge tempe...

by Andrew Glikson Enrico Fermi, Physicist , 1901-1953 According to  Fermi’s Paradox , the failure to date to achieve radio communication between Earth and extraterrestrial civilizations can be attributed to their inevitable short-term self-destruction, a consequence of uncontrolled dispersion of toxic substances, contamination of air, water and land, and construction of deadly weapons. On Earth this includes saturation of the atmosphere by greenhouse gases and production of nuclear weapons.  The most extensive mass extinction event in the history of Earth, represented by the Permian-Triassic boundary 251 million years-ago, involved warming, acidification and oxygen depletion of the oceans, with consequent emanations of toxic H₂S and CH₄, leading to a loss of some 57% of biological families, 83% of genera and 81% of marine species . If the history of the 21st century is  ever written  it would report that, while large parts of the planet were becoming uninhabitable,...
