August in the Southern Hemisphere is kind of like February in the Northern Hemisphere. This is the Southern Hemisphere's winter. But almost all of South America has been under a giant heat dome. These are record high temperatures, topping at over 100 in many places. This would be extreme hot weather, even for the summer months in the Southern Hemisphere. So they're having an extra hot summer in the middle of winter.

quote “South America is living one of the extreme events the world has ever seen,” weather historian Maximiliano Herrera tweeted, adding, “This event is rewriting all climatic books.” The most extreme conditions have occurred in the southern half of the continent, and particularly in the Andes Mountains region. Temperatures Tuesday rose past 95 degrees (35 Celsius) in numerous locations, including at elevations of about 3,500 to 4,500 feet in the Andes foothills. In some cases, the temperature crested above 100 degrees (38 Celsius) after leaping from morning lows in the 30s and 40s (single-digits Celsius). Some places have even reached all-time maximums—surpassing summer temperatures, even though it is winter. This has occurred in locations with 20 to 30 years of climate data available, showing how exceptional this heat is compared with recent decades.

Here's a "short one" from CubaSi:

"Study finds human activity responsible for record July temperatures"

Complete report:

quote A new study finds this month’s record-shattering global heat wave would not have been possible without the continuing buildup of greenhouse gases in the Earth’s atmosphere due to human activity. Scientists at World Weather Attribution say a rapid analysis of weather data taken this month across China, southern Europe and the American Southwest show high levels of carbon dioxide and other gases helped drive temperatures by as much as four-and-a-half degrees Fahrenheit above pre-industrial levels. The researchers warn the past 20 days have likely been the hottest such stretch in more than 100,000 years. This comes as new research finds sea ice around Antarctica is in sharp decline and may never recover. Data from the University of Maine’s Climate Change Institute show almost 2 million square kilometers less sea ice has accumulated so far during the Southern Hemisphere’s winter compared to any previous year.
