Slow Burn Minsky Moments.

Limitless 'white' hydrogen.

1. The world just had its hottest June ever for land and sea, with ocean temperatures setting new highs for the third month in a row. Combined ground and ocean temperatures across the Earth were 1.89F degrees (1.05C) above the 20th-century average of 59.9F, making this the warmest June in data going back 174 years, the US National Centers for Environmental Information said in a statement. It’s “virtually certain” that this year will rank among the 10 warmest on record, the agency said. (Source: bloomberg.com)

2. White Paint and Global Temperatures:

As the climate crisis worsens, scientists have been urgently working to develop reflective materials, including different types of coatings and films, that could passively cool the Earth. The materials rely on principles of physics that allow thermal energy to travel from Earth along specific wavelengths through what’s known as the transparency or sky window in the atmosphere, and out into deep space.

Jeremy Munday, a professor of electrical and computer engineering at the University of California, Davis, who researches clean technology, said this redirection would barely affect space. The sun already emits more than a billion times more heat than the Earth, he said, and this method merely reflects heat already generated by the sun. “It’d be like pouring a cup of regular water into the ocean,” Dr. Munday said.

He calculated that if materials such as Purdue’s ultra-white paint were to coat between 1 percent and 2 percent of the Earth’s surface, slightly more than half the size of the Sahara, the planet would no longer absorb more heat than it was emitting, and global temperatures would stop rising.
