Climate Science made simple, 169 yrs ago, by a woman.

“In an 1856 issue of TAJS, Eunice Foote made an eerily prophetic observation: What happened inside the CO2 jar could also happen to our planet. “An atmosphere of that gas, would give to our earth a high temperature.”

Today’s headlines make climate change seem like a recent discovery. But Eunice Newton Foote and others have been piecing it together for centuries.

This graph of global solar cell installation shows how the world has already left the Liberal Party behind in the coal dust. The future is renewable, it’s ubiquitous and far cheaper than fossil fuels. If only the sun could donate!

like romeo, the liberal party has taken its own political life after believing a fatal lie — that net zero policies have driven up power prices.

Leapmotor will cross 400K BEVs this year
XPeng as well
and even Xiaomi, not impossible

these three brands will add more BEVs to our planet this year,
than half of the existing German BEV fleet (one of the biggest fleets in the world today)

think about this for more than 1 second

Batteries are coming to Europe. Earlier this year Europe’s largest battery storage site went live at Blackhillock, Scotland.

The facility has a capacity of 300MW/600MWh.

Much larger batteries are under development: A huge 1 GW / 4 GWh system is being constructed in Jänschwalde, Germany.

Good news: more than 50% of the world’s economies have seen carbon emissions from fossil fuel power generation peaking. And with the speed of change in the electricity sector many more will join this growing list in coming years.

This a big deal: "China’s carbon dioxide emissions have been flat or falling for 18 months"

China's economy has grown by ~5% in the last year, so this comprehensively debunks the idea (again) that emissions are tied to growth. So yes, faster progress needed, but this is how you turn the corner.

Solar’s price drop is astonishing: panels are now 98% cheaper than when I first analyzed them in 2004.

Today, building a fence with solar can be cheaper than using wood.

ICE vehicles waste a whopping 80% of the energy in their fuel. Electric vehicles are propelled by entirely different mechanisms. Energy enters the vehicle as electricity, which directly powers the drivetrain: EVs need not convert one form of energy to another resulting in much higher efficiency.

One of the unacknowledged advantages of this awful era is that it's revealing for all to see the putrid connections between great wealth and great power.

The intentions of the oligarchs are fully exposed and more blatant than ever.

But remember: We outnumber the oligarchs.
