Over the last two decades, Earth has lost a little bit of its shine -- and no, not just because of the world-changing pandemic. By studying the glow of our humble space orb, scientists have discovered a surprising dimming. They hypothesize the underlying cause could be related to climate change.
In a study, published in the journal Geophysical Research Letters on Aug. 29, researchers examined the Earth's "albedo" by analyzing earthshine at the Big Bear Solar Observatory in California between 1998 and 2017 -- equivalent to around 1,500 nights of data. This analysis allowed them to assess how much light is reflected by the planet.
The data revealed the Earth has dimmed by about half a percent since the late 1990s.
By watching the moon for two decades, the research team were able to detect small changes in the albedo. Particularly in the last few years, the shine has really come off our Earth.
Comparing their findings with those of NASA's Clouds and the Earth's Radiant Energy System (CERES) project, which features five satellites measuring reflectiveness, the team suggest the reduction in low-lying clouds over the eastern Pacific may have resulted in the precipitous drop off in brightness. These reductions in cloud cover may be caused by increases in sea surface temperatures, with "likely connections" to the climate crisis.
The team note in their conclusions that albedo analysis from earthshine can be prone to a lack of sensitivity because of long-term calibration issues and encourage further analysis of the Earth's brightness.

Trump’s Fault #3,487,906,542,176. Really, it is the fault of capitalism, the fault of SUVs and Pickups. Stupid article written by a moron...
Here we go again. The ritualistic clutching of pearls about poor, poor Mother Earth. The earth can be surprisingly resilient at times, unassisted by man. I recall several stories of oil tankers accidentally releasing incredibly enormous amounts of crude into the oceans.
After several weeks of rage and hysteria in the news, there was evidence that a large portion of this crude oil was somehow reabsorbed into the earth. I’m no geologist, so this is a very simplified explanation, but sometimes the earth is far stronger than we give it credit for.

Good one!
OMG the sky is falling, the sky is falling... /s
Solar panels are built to specifically restrict sunlight reflection.
Change a wheel? Dig a trench?
Dang ol revenuers always busting up my stills. Good shine is hard too come by. Likes me some good shine.
These “experts” need to start doing their part by bringing their carbon footprint to zero to “keep us safe”.
Change a wheel? Dig a trench?
Not on your life.
This is really pathetic propaganda almost to Berlin_Freepers level.
Pegs?
Hell, there has been plastic deformation of the d’arsonval movement spring.
Yup
I suspect that these scientists don't want us to know that climate change is also happening on Jupiter.
Notice how “climate change” morphs into “climate crisis” in a few short paragraphs
What next...

translation: we need more money to figure this out.
It is NOT global warming. The real reason is the lowering IQ caused by various Dem programs from schooling and fake news and vaccines. The light bulbs have changed down to 40 lums.
Climate change! Of course.
“THAT’S how I can keep that sweet sweet albedo grant money flowing in.”
As I understand it, the “climate change” of recent decades has been greeted with world-wide re-forestation of the planet and that there is more forest land on earth than has been there for decades. I wonder if possibly this could impact “earth-shine”. Seems a more plausible theory than clouds over the pacific....
