Baffled Scientists Say Less Sunlight Reaching Earth

After dropping for about 15 years, the amount of sunlight Earth reflects back into space, called albedo, has increased since 2000, a new study concludes.

That means less energy is reaching the surface. Yet global temperatures have not cooled during the period.

Increasing cloud cover seems to be the reason, but there must also be some other change in the clouds that’s not yet understood.
