Since 1977, NASA has been continuously studying Earth’s energy budget by flying instruments aboard satellites with the Clouds and the Earth’s Radiant Energy System (CERES) project. These have delivered detailed measurements of the planet’s radiation budget: how much enters, how much escapes, and how much soaks into the oceans. The new study is the first to account for human activities—as well as natural factors such as water vapor, clouds, and surface reflectivity—to precisely pin down the Earth’s energy imbalance, the “distinct fingerprints of anthropogenic activity in Earth’s changing energy budget.”
The study concluded human activities increased this imbalance, also known as “radiative forcing,” by about 0.5 watts per square meter between 2003 to 2018, mostly due to rising greenhouse gas concentrations. For context, that’s about the equivalent of keeping nearly 5 trillion 60-watt light bulbs lit across the Earth’s surface all the time.

Joe Biden invites 40 world leaders to virtual summit on climate crisis
Joe Biden has invited 40 world leaders to a virtual summit on the climate crisis, the White House said in a statement on Friday. Heads of state, including Xi Jinping of China and Russia’s Vladimir Putin, have been asked to attend the two-day meeting meant to mark Washington’s return to the front lines of the fight against human-caused climate change, after Donald Trump disengaged from the process.

Last time I ran the numbers another comparison would be like every man, woman and child all ~7B of us each running a 1200w microwave 24/7/365.

Google says that Earth's surface area is 510 million square kilometers
1000 meters in a km, so 510E12 square meters
0.5 watt per square meter -> 255 E12 watts or 255 TW
Look right ? It's different than your calc:
7E9 people * 1.2E3 watts = 8.4 E12 watts = 8.4 TW

Scientists Support an Idea Long Thought Outlandish: Reflecting the Sun’s Rays Scientists Support an Idea Long Thought Outlandish: Reflecting the Sun’s Rays
The idea of artificially cooling the planet to blunt climate change — in effect, blocking sunlight before it can warm the atmosphere — got a boost on Thursday when an influential scientific body urged the United States government to spend at least $100 million to research the technology.
The report acknowledged the risks that have made geoengineering one of the most contentious issues in climate policy. Those risks include upsetting regional weather patterns in potentially devastating ways, for example by changing the behavior of the monsoon in South Asia; relaxing public pressure to reduce greenhouse gas emissions; and even creating an “unacceptable risk of catastrophically rapid warming” if governments started reflecting sunlight for a period of time, and then later stopped.

Yeah... I misremembered the comparison. It's not 'a' microwave. It's ~30. Every person running ~30 microwaves 24/7/365.
Maybe smarter to further develop heat pump technology so that we can draw heat from the air to generate electricity (instead of geothermal). This would be great along the equator and during the day. I know this would be awesome in Vegas from May thru Oct. LOL
Need a significant temp gradient/delta between two sinks. Geothermal "works" since the temp down there is much greater than surface temperatures.
This is great.

If you haven't seen this one yet, I highly recommend it. We love all things David Attenborough and have watched everything he has put out...even owning the Planet Earth series on Bluray when that was a thing to do.
We just watched this last night and man is it powerful. There's nobody more qualified to tell it like it is than this man....

Cherry blossoms' earliest peak in 1,200 years linked to climate change
Kyoto's not alone in early blooms this spring, with cherry trees in Tokyo and D.C. also peaking early.

'Immediate and drastic.' The climate crisis is seriously spooking economists
Worsening inequality, trillions of dollars in economic damage and depressed economic growth. Those are the outcomes that economists fear we will face unless the world aggressively confronts the climate crisis.

New York (CNN)Worsening inequality, trillions of dollars in economic damage and depressed economic growth. Those are the outcomes that economists fear we will face unless the world aggressively confronts the climate crisis. Nearly three-quarters (74%) of economists agree "immediate and drastic" action is warranted to curb emissions, according to a survey released Tuesday from the Institute for Policy Integrity at the NYU School of Law. That's up sharply from 50% in 2015. Since that time, the United States has been hit by an onslaught of extreme and deadly weather events including Hurricane Maria, massive wildfires in California and this year's deep freeze in Texas. With those floods, wildfires and hurricanes occurring more frequently, the financial toll from the climate crisis is expected to rise dramatically: Economic damage from climate change is projected to reach $1.7 trillion per year by 2025 and surge to roughly $30 trillion annually by 2075 under most scenarios, according to consensus forecasts included in the survey.

Elite minority of frequent flyers 'cause most of aviation's climate damage'
An “elite minority” of frequent flyers cause most of the climate damage resulting from aviation’s emissions, according to an environmental charity. The report, which collates data from the countries with the highest aviation emissions, shows a worldwide pattern of a small group taking a large proportion of flights, while many people do not fly at all.An “elite minority” of frequent flyers cause most of the climate damage resulting from aviation’s emissions, according to an environmental charity.

Possible, the group that produced the new report, is calling for the introduction of a frequent flyer levy, whereby the first flight in a year incurs little or no tax and it therefore does not penalise annual family holidays. But the levy then ramps up for each additional flight.

Yes, this is a magnificent - if saddening - set of data. The headline is incorrect, unfortunately; it should state “...in at least 1200 years”.Cherry blossoms' earliest peak in 1,200 years linked to climate change

But to have one thousand two hundred years of data! NOT tree rings or ice cores or lake-bottom sediments (none of which I disparage), but written down - fantastic.

Nobody takes a flight for the food, lol...they need to be somewhere, usually as part of their job. That doesn't make them "elite" class. I had such a job that required me to be on-site all over the country, although I knew it was time to move on when the bartender at O'Hare asked me "the usual?" omg.
I could argue the same thing about cars. There are about 1.2B cars in the world, making drivers the minority "elite" class, rite?
