Marking the latest CO2 records is not an act of celebration, but of bearing witness. CO2 Records
The achievements are a sobering reminder of the chemical changes that we humans are collectively making to the atmosphere–changes with disruptive impacts that affect every living being in the biosphere. When a new record is reached, it is is marked here with an invitation for people to take notice, reflect on the transformation that is going in the wrong direction, and resolve to reverse these trends.
Scientists, climate experts, and governments officials agree that 350 ppm is the “safe” level of carbon dioxide. (hence the climate change activists group name 350.org)

The strong high-pressure system causing this unusually hot weather should last until today before gradually decreasing in size and strength. These abnormally high temperatures closely follow another spell from April 29 to May 5. In fact, some places have not seen much of a break in above-normal temperatures since the end of April. We should expect the higher-than-usual temperatures to continue in these regions for the next few weeks.
These hot and dry conditions have further fuelled the hundreds of wildfires already burning in western Canada. The resulting smoke is causing poor air quality and reduced visibility, prompting air quality statements in British Columbia, Alberta, Saskatchewan, and Manitoba. Last week, the wildfire smoke spread across the entire country, reaching as far as the Atlantic Ocean.
Spain breaks record temperature for April – BBC News
April 28, 2023 – BBC News
Spain recorded its hottest ever temperature for April on Thursday, hitting 38.8C according to the country’s meteorological service.
The record figure was reached in Cordoba airport in southern Spain just after 15:00 local time (14:00 BST). For days a blistering heatwave has hit the country with temperatures 10-15C warmer than expected for April. It’s been driven by a mass of very hot air from Africa, coupled with a slow moving weather system.
