Human Extinction by 2022?

The NASA image below shows the October 2021 temperature anomaly. The Arctic is heating up enormously, with anomalies showing up of up to 9.1°C.  The image below shows that the global temperature over the past century, i.e. from 1920 to 2020, has risen by 1.3°C. The image shows anomalies from 1900-1920. When adjusting data to reflect a pre-industrial base, ocean air (2m) temperatures and higher polar anomalies, temperatures may have crossed 2°C long ago. The image below shows two trends, based on NASA 1880-October 2021 data, adjusted to reflect a pre-industrial base, ocean air (2m) temperatures and higher polar anomalies. The linear trend (green) misses the point that the temperature rise is accelerating. The polynomial trend (black) shows the potential for 3°C to be crossed by 2026. Acceleration of the temperature rise may speed up further soon, for a number of reasons: Aerosols: As cleaner alternatives become more economic, and as calls for cleaner air become stronger, thi

The road to zero emissions is strewn with "alternative facts"

by Andrew Glikson Once again, the hopes of billions have been raised, only to be dashed, this time by the cruel joke of COP26, the reality being that “ By 2030, governments are planning to extract 110% more fossil fuels than their Paris Agreement pledge to limit the temperature increase to 1.5°C above pre-industrial levels would permit ”. Misrepresentations abound: The United Nations upper global temperature target of 1.5°C takes no account of the fact that, without the transient short-lived aerosols effect of over 0.5 to 1.0 Watt/m⁻² , the mean global heating is nearing ~2.0°C. It is the cumulative concentration of greenhouse gases in the atmosphere, which controls temperatures, triggering feedbacks from land and oceans, and which has reached a high level of combined CO₂+CH₄+N₂O of >500 ppm CO₂-equivalent . Only sequestration / drawdown from this level may be able to lower terrestrial temperatures. Polar temperature changes are critical: The Arctic temperature anomaly reache

The exclusion of climate science from COP meetings

 by Andrew Glikson There can be little doubt that, had the US, China and Russia been on the same page, an advanced agreement was likely to be reached at COP26 , but since it is not, the collapse can be laid at the feet of human tribalism and eternal conflict since the dawn of civilization, ultimately leading to a mass extinction of species . Climate scientists have practically been excluded from COP meetings, dominated as they are by economists, lawyers and politicians. To date no address has been made by leading climate scientists, including authorities such as James Hansen , Michael Mann , Joachim Schellnhuber , Will Steffen and other , leaving delegates and populations unaware of the ultimate consequences of global climate devastation. With the exception of David Attenborough and references to “ one minute to mid-night ”, the science-based projections of global heating have only received faint echoes among the assembly of warring tribes at COP-26, dominated by nationalism, vested i
