    Some tree leaves are finding it too hot for photosynthesis

    Earth’s ongoing fever threatens to push entire forests toward this heat limit — and possible death.

    Explainer: Why are so many hurricanes strengthening really fast?

    This dangerous trend appears relatively new — and growing. Studies also have begun linking it to our warming world.

    Hydrogen energy could help our climate — depending on its source

    Hydrogen energy doesn’t emit greenhouse gases when it’s used. But how it’s produced will affect how useful it can be in slowing climate change.

    Explainer: The hydrogen rainbow

    Hydrogen works the same, regardless of its source. But how clean or “green” it is very much hinges on its color-coded name — which points to how it was made.

    Engineers cook up a new way to tackle CO2: Make baking soda

    Engineers have found a material that can collect carbon dioxide from the air. When later mixed with water, it forms baking soda that can be shed in the sea.

    A new hydrogel could help pull drinking water from the air

    The salty gel absorbs more water from the air than similar gels, even in desert climates. This could provide clean water for drinking or farming.

    Adult corals have been frozen and revived for the first time

    Living corals could be frozen for safekeeping. Scientists could later revive them to restore reef ecosystems that are withering in warming seas.

    Summer 2023 is when the ocean first turned ‘hot tub’ hot

    Unfortunately, scientists worry that this atypical sea warming may actually be the beginning of an unwelcome new ‘normal.’
