A huge temperature rise threatens to unfold, as the already dire situation threatens to turn catastrophic due to the combined impact of a number of developments and feedbacks.  The image below uses ERA5 data, with two trends added. The blue trend, based on 1940-2022 data, points at 3°C rise by 2044. The purple trend, based on 2008-2022 data, better reflects variables such as El Niño and sunspots, and shows that this could trigger a rise of as much as 3°C by 2025, as further discussed below. Note that anomalies are from 1850-1900, which isn't pre-industrial. The upcoming El Niño Temperatures are currently suppressed as we're in the depth of a persistent La Niña event. It is rare for a La Niña event to last as long as the current one does, as illustrated by the NASA image below and discussed in this NASA post . The blue line added in the image highlights an increase in peak ONI (strong El Niños) over the years.  The above image was created using data up to September 2022. La Niñ...

NOAA's October 2021 global mean methane reading is 1907.2 parts per billion (ppb), which is 17.1 ppb higher than the reading for October 2020. By comparison, NOAA's annual global mean methane increase of 15.74 ppb for 2020 was at the time the highest on record. Keep in mind that this 1907.2 ppb reading is for October 2021; it now is February 2022. Furthermore, NOAA's data are for marine surface measurements; more methane tends to accumulate at higher altitudes. The  image below shows that the MetOp-B satellite recorded a peak methane level of 2904 ppb at 469 mb on February 4, 2022 am.  Methane levels are very high over the Arctic. The image below shows high recent monthly average methane levels at Barrow, Alaska.  Carbon dioxide levels over the Arctic are also very high. The image below shows high recent daily average carbon dioxide levels at Barrow, Alaska.  The situation is dire and calls for the most comprehensive and effective action, as described at the Climat...

by Andrew Glikson “We are simply talking about the very life support system of this planet.” Hans Joachim Schellnhuber , Germany’s former chief climate scientist (2009) “Burning all fossil fuels would create a very different planet than the one that humanity knows. The palaeoclimate 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 400,000 Hiroshima atomic bombs per day 365 days per year” . James Hansen et al. 2012 and James Hansen 2012 . Figure 1. The change in state of the planetary climate since the onset of the industrial age in the 18ᵗʰ century. During its last 600 million years-long history planet Earth suffered at least five major mass extinctions, defining the ends o...

At the Paris Agreement in 2015, politicians pledged to limit the global temperature rise from pre-industrial levels to 1.5°C and promised to stop rises in greenhouse gas emissions as soon as possible and to make rapid reductions in accordance with best available science, to achieve a balance between people's emissions by sources and removals by sinks of greenhouse gases in the second half of this century.  Yet, greenhouse gas levels keep rising and the rise appears to be accelerating.  Carbon Dioxide The annual mean global growth rate of carbon dioxide (CO₂) has been increasing over the years (see above image). The February 2021 global CO₂ level was 2.96 ppm higher than the February 2020 global CO₂ level (image left). The March 2021 global CO₂ level was 2.89 ppm higher than the March 2020 global CO₂ level (image left), again much higher than the average annual growth rate over the past decade.  No discernible signal in the data was caused by restrictions associ...
