The average brain weighs 1300-1400 grams. If 0.5% of that is plastic by weight, your brain contains 6.5 - 7 grams of plastic. The average plastic credit card weighs 5 grams.

When scientific studies showed that the extreme temperatures were caused by heat domes, which experts say are influenced by climate change, county officials didn’t just chalk it up to a random weather occurrence. They started researching the large fossil fuel companies whose emissions are driving the climate crisis—including ExxonMobil, Shell, and Chevron—and sued them.

Now, 11 months after the suit was filed, Multnomah County is preparing to move forward with the case in Oregon state court after a federal judge in June settled a monthslong debate over where the suit should be heard.

A new study published in Nature Ecology & Evolution shows that the number and intensity of the most extreme wildfires on Earth have doubled over the past two decades.

The authors of the new study, researchers at the University of Tasmania, first calculated the energy released by different fires over 21 years from 2003 to 2023. They did this by using a satellite-based sensor that can identify heat from fires, measuring the energy released as “fire radiative power.”

The researchers identified a total of 30 million fires (technically 30 million “fire events,” which can include some clusters of fires grouped together). They then selected the top 2,913 with the most energy released, that is, the 0.01 percent “most extreme” wildfires. Their work shows that these extreme wildfires are becoming more frequent, with their number doubling over the past two decades. Since 2017, the Earth has experienced the six years with the highest number of extreme wildfires (all years except 2022).

When the world is warmer, it is likely to have more extreme weather and climate events, including record heat and rainfall, scientists say. And climate change is also changing weather patterns, leading to rainy and hot systems stalling over areas and the jet stream meandering, said Alvaro Silva, a climate scientist at the World Meteorological Organization.
