Since 2000 the Earth’s ALBEDO has decreased by about -0.6%. Most of the decrease (-0.5%) happened since 2014.

On average, about 30% of the sunlight that hits the Earth bounces back into space.
The planetary albedo helps determine the Earth’s average temperature. If the albedo rises (meaning that more light gets reflected back to space), all other things staying equal, our planet gets cooler. If the planetary albedo declines, the earth warms up.
Here’s the bad news: the Earth’s albedo has been declining during the last 20 years. BY A LOT, although it seems like a small amount.
Here’s what James Hansen stated in his post, Large Cloud Feedback Confirms High Climate Sensitivity 2025 — May, 2025
Earth’s albedo (or reflectivity) is the portion (percent) of incoming solar radiation that is reflected back to space. As shown in Fig. 1, in the period of precise satellite data (since early 2000), Earth’s albedo has decreased about 0.5%.
We described this change as a BFD (Big Fucking Deal) because it has staggering implications. Solar radiation reaching Earth is about 340 W/m2, averaged over Earth’s surface, so the 0.5% albedo decrease is a 1.7 W/m increase of absorbed solar energy.
A +1.7 W/m2 increase of absorbed solar energy is huge. If it were a climate forcing, it would be equivalent to a CO2 increase of +138 ppm. — James Hansen
It’s LIKE ADDING +138ppm OF CO2e to the atmosphere SINCE 2014.
+138ppmCO2e in JUST 11 YEARS.
For context:

That's about 7,000 years of “normal” CO2 increase IN JUST 11 YEARS.

That's “how significant” this change in the planetary albedo is. It massively accelerates and amplifies the warming caused by increases in CO2 and CH4.
If this change happened by itself, that sudden JOLT of ENERGY into the Climate System would be bad enough. However, there are several other factors that are also making things worse.
Our CO2 emissions have increased the atmospheric CO2 level by +58ppm since 2000.
That’s 3,000 years of “normal” interglacial CO2 increases. In just 25 years.
It took 150 years (1850–2000) to increase the CO2 level by +90ppm (280ppm to 370ppm).
Between 2000 and 2025 we increased the CO2 level by about 2/3rds of that amount (+58ppm).
At the present rate of increase (+3ppm/year), we will finish the second +90ppm in about 10 more years.
280ppm to 370ppm = 150 years.
370ppm to 460ppm = 35 years.
That's a +400% increase in the rate of CO2 increase.
The atmospheric CO2e level has increased by about +196ppmCO2e since 2000 from just CO2 emissions and a dimming albedo. Just those two things increase the CO2e level to around +570ppmCO2e.
In addition to that there is the rising level of atmospheric CH4 or methane.
Since 1850 the level of atmospheric CH4 has increased from 800ppb to over 1900ppb. Since 2000 the increase has been about +175ppb.
The current level of CH4 adds the equivalent of about +100ppm of CO2e to the atmosphere.
Which puts the CO2e level from CO2 emissions, the dimming albedo, and the massively elevated CH4 level at around +670ppmCO2e.

NO MATTER WHAT WE DO NOW — THESE THINGS HAVE ALREADY HAPPENED.
These things are facts and they have CONSEQUENCES.
Now.
You can argue about the exact CO2 equivalence of 1900ppb CH4. Should it be 100ppmCO2e, or 75ppmCO2e, or 125CO2e?
You cannot argue the methane concentration is not higher than it has been in millions of years.
Food for thought:

You can argue about the exact amount of change in the Earth’s Albedo and whether or not it’s due to “natural variation”.

You can argue about WHY the albedo has dimmed over the last 25 years. Is it about cooling SOx aerosols being washed out of the atmosphere as we stop burning high sulfur coal and oil or is it about a decline in the global amount of cloudiness?

You cannot argue that the albedo has not dimmed or that after 10 years (2014–2024) this dimming seems persistent, stable, and has TRIPLED the amount of ENERGY going into the Climate System since 2010.

You can argue about the significance of increasing the atmospheric concentration of CO2 by +58ppm since 2020. Will going from 370ppm to 425ppm increase the Global Mean Surface Temperature just the +1.5°C we have observed so far, or will it raise the GMST the +4°C over baseline that the paleoclimate record and the Alarmist models indicate?

What you cannot argue with is that CO2 levels have increased by +58ppm since 2000.
These things are FACTS and we cannot change them now no matter what we do, or say, or pledge to do in the future. The DIE is cast now and these things will shape the planetary climate over the rest of this century as the consequences of our choices manifest themselves.
You can interpret these facts in different ways but you don’t get to argue about these things. They are the facts of the current Climate Crisis.
Here is one of the CONSEQUENCES.
The oceans are heating up. A LOT.

Notice that the baseline here is a 1993 to 2023 average. If you used an older period for the ocean temperature, the warming would be even more pronounced.
In this view the baseline is a 1991 to 2020 average.

This ocean warming has not been evenly distributed across the planet. Heat tends to “build up” in places.
Which we can see today.
This ocean warming doesn’t stay in the ocean. That HEAT moves into the atmosphere and makes things HOT.

This HEAT has consequences BIG and small that are rippling across our world. One of the more important is that food is getting more expensive.
In both small ways.
The global price of olive oil shot up to $10,600 per metric ton in April, up from $5,300 in March. Production of olive oil in Greece and Italy is down, as heat jeopardizes the harvest. The high prices have sparked a spate of olive-related crimes, with people stealing olives and the oil extracted from them in Halkidiki, Crete and Kalamata. This is a big deal in Greece, where olive oil is responsible for not only 7 percent of the country’s gross domestic product but also 25 percent of Greek agriculture.
and LARGE ways.

You can argue about the significance of these facts but you cannot change them.
The die has already been cast.
Now we find out HOW BAD what we have done is going to be.
This is my analysis.
This is what I see.
This is my “Crisis Report”.

ADDENDUM:
As always, Richard Crim, your The Crisis Report is a goldmine of sad but ultimately enlightening information. I encourage all reading this Note to check him out and subcribe to his channel.
Thank you for everything you do Richard. Been a follower for a year at this point. Your information and analysis is incredibly beneficial for people like me that aren’t able to parse thru all the data and news happening around the world in relation to CC.
Do you think the wealthier western countries will be delayed in experiencing the worst of the what’s about to come? Or do you think the detrimental effects to food and water security will be felt no matter where in the world you are?
