Reason #1 to be optimistic: Renewable energy has become cheap. Agree.
(Hey @Trouw , that's not $ per megawatt, but per MWh)

Ritchie's reason #2b to be optimistic:
- India's per capita emissions from coal are low. True.
- China's are 'many times lower than the US/UK peaks'. Hmm. Roughly two times, rather.
Four pages on Hannah Ritchie and her book Not the End of the World in @Trouw today. Data on positive developments led her to 'urgent optimism' on climate change: achievements in the past call for acceleration action for clean energy and environment. 🧵

Hannah Ritchie on climate change itself: "Global warming of 2.5 to 3⁰C is catastrophic, and it will hit the poorest, who least contributed to global warming, the hardest."
New reconstruction of atmospheric CO2 history:
The Miocene (~16 Ma) marks the last time that CO2 concentrations were consistently higher (~480 ppm) than now; Greenland was not yet glaciated at that time, and sea level was some 50 m higher than today.

When I was a kid, global warming was hardly noticeable.
When I was studying physics in university, it was clearly happening, at almost 0.2⁰C per decade.
And now, it has accelerated further, to about 0.3⁰ per decade.

December 2023 was by far the warmest December on record globally, with an average surface air temperature of 13.51°C, 0.85°C above the already warmed 1991-2020 average for December and 0.31°C above the temperature of the previous warmest Decembers, in 2015 and 2019.

It's ironic that the water in these plastic bottles, of which quite a few end up in the environment, now contains bits of that plastic too.
Researchers discover thousands of nanoplastic bits in bottles of drinking water. 90% were small enough to qualify as nanoplastics: so small that they can be absorbed into human cells and tissue, as well as cross the blood-brain barrier.

Almost Christmas and it was 25⁰C in northern Italy yesterday!
From @extremetemps on the birdsite.
25.2C yesterday at Cumiana (Turin Province) is the new official highest temperature in December in Northern Italy.
4 stations with 25C+ in Piedmont.
In Emilia 24.2C at Vignola.

1 m² of solar panels now give you 38% more power for 83% less money than eleven years ago!

Spain's winter heatwave just got worse. 29.9⁰C (86F) in Malaga today!
That's 12⁰C (22F) above normal for December.
Highest temperature ever recorded in Spain in December.
#globalwarming #ClimateChange
I'm old enough to remember that 24.8⁰C was an all-time high temperature for December in Malaga: that was 2 years ago...

Ok, your flight may take 30,000 liters of fossil kerosene, but it's now delivered by a fully electric dispenser truck!
Tripling nuclear power capacity by 2050 might increase its share in growing global electricity demand from 10% now to ~12% by 2050.
The target is very optimistic, though: capacity growth for the coming decade is already fixed, and it will take years to ramp up the supply chain.

2,000 MW of solar PV, built at an average rate of 10 MW per day!
Will probably produce around 4 TWh per year, at a very low cost, claimed to be $0.0132 per kWh (but @solar_chase always warns us that these auction prices aren't real costs ;).

#renewables #renewableenergy #SolarPV #solarpower
As recently as 2007, less than 10 MW/day of solar PV was built in the whole world! Now, it's the speed of construction at one solar power plant.
We're moving!
