Smoke over North America

High levels of biomass-burning aerosols show up over North America on the above June 7, 2023 06 UTC forecast by Copernicus. The above satellite image shows the US East Coast, with New York blanketed in a veil of smoke on June 7, 2023.    High levels of carbon monoxide are visible over North America on the above map. Carbon monoxide is forecast to be as high as 8715 parts per billion in Quebec, Canada on June 8, 2023 (at 12:00 UTC, a few hours from now, at the green circle). The map below shows the location for this measurement in Quebec, Canada on June 8, 2023 (at red marker).  The image below also shows wind at 250 hPa, i.e. the Jet Stream. The circular wind patterns indicate how deformed the Jet Stream is.  The image below, from an earlier post , further illustrates the extent of the deformation of the Jet Stream, showing the Jet Stream on June 6, 2023, with no less than 26 circular wind patterns (at 250 hPa) marked on the image, which also shows sea surface tempe...

Climate Change Henchmen: Storm, Flood, Heat, Smoke and Fire

As climate change strikes with ever greater ferocity, five henchmen dominate the news: Storm, Flood, Heat, Smoke and Fire. During the first 6 months of 2021, there have been 8 separate billion-dollar weather and climate disaster events across the United States. The U.S. has sustained 298 weather and climate disasters since 1980 where overall damages/costs reached or exceeded $1 billion (including CPI adjustment to 2020). The total cost of these 298 events exceeds $1.975 trillion. The total cost over the last 5 complete years (2016-2020) exceeds $630.0 billion — averaging more than $125.0 billion/year — both new records. The image on the right shows very high temperatures over North America end July 2021, with fire radiative power as high as 247.3 MW. The NASA Worldview satellite image below shows large smoke plumes on July 7, 2021, reaching Hudson Bay. Furthermore, large smoke plumes are also visible over British Columbia. The NASA Worldview satellite image below shows smoke traveling ...

The Australian firestorms: portents of a planetary future

by Andrew Glikson Earth and climate scientist Australian National University Global warming and its disastrous consequences are now truly with us since the second part of 2019. At the moment a change in the weather has given parts of the country a respite from the raging fires, some of which are still burning or smoldering, waiting for another warm spell to flare up. The danger zones include the Australian Capital Territory, from where these lines are written. To date, 18.6 million hectares (186,000 square kilometers) were burnt, including native forests, native animals, homesteads and towns, and 24 people died. The firestorms betray harbingers of a planetary future , or a lack of such, under ever rising temperatures and extreme weather events inherent in fossil fuel driven global warming. Global heating As the atmospheric concentration of the well-mixed greenhouse gases rise (CO₂ > 411.76 ppm;  CH₄ > 1870.5 ppb ; N₂O > 333 ppb plus trace greenhouse gases) lan...
