Hurricane wind speed grew 6 mph per decade
Bermuda gets some protection from hurricane storm surges from of its reefs. But coral is useless at shielding the island nation from winds. Now a study has shown that the maximum wind speed of hurricanes in the subtropical Atlantic around Bermuda (on average) has more than doubled in the last 60 years: from 35 to 73 mph. between 1955 to 2019. Why? Because the ocean surface temperature is rising, explain scientists at University of Southampton, publishing in Environmental Research Letters. The warmer the ocean surface, the more violent the wind, they explain.

After a new report found that greenhouse gas emissions from corn ethanol are 46% lower than gasoline, U.S. Senator Joni Ernst (R-Iowa) – a member of the Senate Environment and Public Works (EPW) Committee – is pushing the Biden Administration to acknowledge the environmental benefits of biofuel and to use the data as part of their policymaking. Ernst is helping reintroduce bipartisan legislation that will require the Biden Administration’s Environmental Protection Agency (EPA) to update its greenhouse gas modeling for ethanol and biodiesel and to fully recognize biofuel’s environmental benefits.

The myth of temporal independence?
Nordhaus 1992 hs been a fat target for disagreement, perhaps especially because the resultant DICE was an early entrant and certainly the most ambitious effort of its day, hence highly conspicuous, widely adopted, possibly prone to oversights especially given its underpinning school of economics. Michael Grubb et al 1992 pointed out some static features built into DICE that might not pan out. 25 years have passed since those observations. Now, Grubb et al 2021 explore how certain features baked into DICE have been propagated in community wisdom and have cemented themselves into educational and policy settings despite their being essentially mythological, unsupported, and yet having profound effects on how our future will unroll:
International Research Team Begins Uncovering Arctic Mystery Details

Something lurks beneath the Arctic Ocean. While it’s not a monster, it has largely remained a mystery.

According to 25 international researchers who collaborated on a first-of-its-kind study, frozen land beneath rising sea levels currently traps 60 billion tons of methane and 560 billion tons of organic carbon. Little is known about the frozen sediment and soil called submarine permafrost even as it slowly thaws and releases methane and carbon that could have significant impacts on climate.
Rising temperatures contribute to child malnutrition and reduced diet quality A woman walks with her children in a farming village outside Dodoma, Tanzania.

A first-of-its-kind, international study of 107,000 children finds that higher temperatures are an equal or greater contributor to child malnutrition and low quality diets than the traditional culprits of poverty, inadequate sanitation, and poor education.
The 19-nation study is the largest investigation of the relationship between our changing climate and children’s diet diversity. It is believed to be the first study across multiple nations and continents of how both higher temperatures and rainfall two key climate change outcomes have impacted children’s diet diversity.
