Fig. 1 - S3 SLSTR (09-10.07.2021) - After a previous series of heat records, temperatures measured in the western US have peaked again.
The Death Valley recorded 53°C, Las Vegas equaled its record of 47.2°C, Phoenix and San Jose have also reached some of their highest values.
Fig. 2 - S3 SLSTR (11.07.2021) - Combined with the drought, it caused tens of fires along the coastal areas and as far as Colorado state.
Fig. 3 - S3 SLSTR (17.07.2021) - A week later, the wildfires have largely spread, such as the 1200 km² Bootleg fire in Oregon.
So far, human activity has caused global temperatures to rise by ~1.1°C.
Fig. 4 - S3 SLSTR (09-18.07.2021) - Mixing these nightly thermal acquisitions shows the wildfires in dark red.
It results in more destructive storms, more intense heat waves, droughts and more forest fires.
Fig. 5 - S3 SLSTR (14.07.2021) - By mid July, very little snow covers the Sierra Nevada. The last 6 years are the 6 warmest years on record.
Fig. 6 - S3 SLSTR (24.07.2016) - Just five years earlier, the snow cover was more extensive by the end of July.
