If the sun was driving the warming, we’d see it in the stratospheric temperatures (which are cooling in line with expectations from the impact of CO2, not warming due to the supposed increase in solar activity). But we have mega-oodles (the SI unit) of additional data that tell us this conclusion cannot be correct. Szarka, H.L.

Solar geoengineering offers a way of mitigating the effects of global warming by reflecting incoming sunlight back into space – thereby cooling the Earth. One way of doing this is to inject aerosols into the atmosphere. To maintain a 1 °C cooling effect, this would cost about $43bn per year to operate. Longer lasting.

For example, Antarctica acts to cool our planet by reflecting solar radiation back to space by virtue of the brightness of its snow surface. In the ocean, 19 marine heatwaves have been recorded between 2002 and 2018. The world’s largest ever heatwave (38.5C

This study provides the most detailed mapping yet of how summer temperatures in 20 urban centers in California, Nevada, Utah, Arizona, Colorado, New Mexico and Texas affected different neighborhoods between 2018 and 2020. The researchers found even greater heat disparities in California than in other states.

Student in the Department of Atmospheric Science at Colorado State University Most people remember the water cycle they learned in school: water evaporates from lakes, rivers, and the ocean, air carrying this moisture rises, cools, condenses, and forms clouds, and these clouds precipitate water back down to the surface.

This environmental spectacle occurs when a large region of extremely hot air, created by a wildfire interacts with cooler air higher up in the atmosphere. The combination of updrafts and downdrafts leads to atmospheric instability similar to the one that creates other whirling air phenomena like ‘ dust devils ’.

It was a bold claim and some researchers initially struggled to accept the implications because it meant that energy must be flowing from the “cool” 6000 K surface of the Sun into the hotter corona – seemingly in violation of thermodynamics. This estimate was later revised upwards to 10 6 K and above. million kelvin (green).
