Plug-in hybrids are a massive 3.5x dirtier than claimed, meaning they barely cut CO2 vs pure petrol/diesel

Meanwhile, petrol cars are nearly 25% dirtier & less fuel efficient than claimed

– Real-world data published by European Commission

Our latest in Nature (rdcu.be/dA6Ko) that coupling climate, epidemiological and trade models - heat stress amplifies health losses to major economic risks, cascading from Tanzania's mining to China's manufacturing and to US/EU/UK's consumption. Remember last summer?

This gorgeous new BBC chart shows how the coldest days on Earth now are warmer than the hottest days before the 1980s.

You know who predicted this would happen with near-perfect precision? Exxon Mobil scientists, in an internal report in 1982. Two versions of the same chart:

The UK government has launched a consultation on its proposals for kickstarting investment into long-duration energy storage (LDES), defined as 6-hour duration or greater (6 hours isn't particularly long!) and excluding lithium-ion from eligibility (ok).

HOT OFF THE PRESS: At COP28 governments committed to tripling the world's installed renewable generation capacity to at least 11,000 GW by 2030.

Latest International Energy Agency analysis instills confidence: We added a historic 510 GW in 2023, up 50% from a year before.

Storage boom: This 200MW/1600 MWh compressed air energy storage project is in a closed mine.

The 8-hour storage plant replaces diesel generators and integrates RE on grid. It creates 750 construction jobs & 70 operating jobs. Storage isn't just batteries!

And I'm really all for tech innovations but there are many exciting ones out there already. Not need for greenwashing magical stuff.

High on a mountain in the Atacama desert, Chile, the European Southern Observatory is building something immense.

It's called the Extremely Large Telescope, and here's a highlight reel of this beast's ultimate capabilities.

If we can scrub from the atmosphere all the carbon emitted by future fossil fuel consumption, plus all the carbon emitted after we almost certainly overshoot a 1.5 degree carbon budget, then yes, the COP28 UAE President and my senior and very distinguished University of Oxford

is due to choose the host & presidency of next year

Host is due to be from Eastern Europe, but Russia is vetoing EU, Armenia & Azerbaijan are vetoing each other…

Per UNFCCC rules:

If no-one is chosen, it will be held in Bonn, with UAE's Al Jaber as president

One of the Themes at COP28 UAE today is Accountability. What can climate litigation cases achieve, directly or indirectly, within the UK’s current climate governance framework?

Will green hydrogen cost declines follow a solar-like pathway? Or are they more like batteries? Perhaps something else entirely?

In an excellent report Ramboll - an EPC firm - makes the case that electrolyser plants could be a mix of all 3.

Here's what that means for H2 capex:

One focus of COP28 UAE discussions today is accelerating . Nem Vaughan & Dr Nick Brooks discuss a range of overlapping & interacting mismatches influencing global action on climate change adaptation & mitigation, asking what can the IPCC do to speak to these issues?
