"Earth is getting dimmer, researchers have found, and climate change is likely to blame. As the oceans get hotter, they appear to be generating fewer bright clouds, which means less sunlight is reflected back into space – and that warms up the planet even more.

Researchers measured the reflectance or albedo of Earth by observing the earthshine that illuminates the Moon. Nearly 20 years of data, from 1998 to 2017, was collected to inform the results of the study.

The measurements showed that Earth is now reflecting about half a watt less light per square meter compared to 1998, the equivalent of a 0.5 percent decrease in Earth's reflectance. In total, our planet reflects about 30 percent of the sunlight that reaches it."

    Look, it's a new feedback loop :yea:

    And it's not the only one related to albedo either - disappearing ice in the Arctic does that, too (blue sea water reflects much less energy than white sea ice).

    Oh neat! Maybe the increase in wildfire smoke will cancel it out :yea:

      These ecosystems are doing their absolute best to get back to equilibrium and we keep being like "No I want to put my mcmansion in the middle of a forest that burns down every year"

      There’s always plan B if that doesn’t pan out. :posadist-nuke:

      I feel we will try to some weird geo engineering from elon musk, and it ends up making things worse.

    Sighing and adding another item to the list of "Things that will help kill a statistically significant portion of life on Earth within the century".
