In recent weeks, there has been a remarkable surge in large, intense, fast-moving, and unfortunately in many cases destructive/deadly wildfires in multiple Northern Hemisphere regions spanning a wide range of climates & ecologies, but they all share one key commonality. [Thread]

It's not quite "gobsmackingly bananas" but monster forecasts for the record El Nino brewing the Pacific Ocean get pretty close. Here's what to make of it in my first for @nature.com: 🧪 www.nature.com/articles/d41...

This El Niño is set to be the largest on record by a ‘mind-blowing margin’

Forecasters predict that the monster climate pattern will combine with global warming to push global temperatures in 2027 to new heights.

Another lightning outbreak now ongoing in PacNW (TS Elida's remants), & this time fuels are considerably drier west of Cascades following recent heat. Numerous additional wildfire ignitions are likely across much of OR/WA over next 48 hr, worsening existing outbreak. #ORwx #WAwx

In which I yell at my favorite journal and its thoughtful, talented collection of researchers that we really need to take fossil phase-out seriously as a line of inquiry, and that we would not stand for the level of talking around it as a solution in other settings with very obvious problems:

I wonder, if you polled people, how much extra they would pay each year to have their city *not* be covered in thick, choking wildfire smoke for days at a time. I wonder if that might give you more insight into "willingness to pay" vis a vis climate change than asking in the abstract.

A major thunderstorm outbreak is unfolding across the interior Pacific NW. While not "dry thunderstorms" (w/briefly heavy showers), numerous wildfire ignitions are still likely due to strikes outside of rain cores, severe pre-existing drought, & heatwave to follow. #ORwx #WAwx

What happens when the forest behind a carbon offset project burns down? Most carbon crediting programs have an insurance program; few use real numbers, so most aren't prepared for actual forest risks. The Paris Agreement Crediting Mechanism might change that with a proposed empirical approach.

A quick and time-sensitive question for the internet hive mind: What's the best reference for the embodied emissions in solar photovoltaics manufacturing (e.g., gCO2e/kWh)? (I'm looking for numbers, not a debate. I know the emissions are small relative to the value of displacing fossil fuels.)

It seems to have become commonplace to blame net zero for Britain’s high energy bills and/or weak job market… … and I guess I’ll have to explain again why there is very little evidence of this. Britain has plenty of economic problems; net zero is not high on that list (though climate change is) 🧵

1/ A common move in energy/climate public writing is: argue that decarbonization has shifted from a shared public sacrifice to a competitive advantage, contend that self-interest will drive the transition.

1/ The purpose of green industrial policy has inverted. It used to pay for a public good: clean energy that cost more, benefiting everyone. Now it captures advantages a country keeps for itself. That shift, from a shared cost to a prize seized, is the story of the transition.

Makes perfect sense that CDP is literally selling out to a private equity firm. Its continued relevance requires ongoing demand for this voluntary reporting standard. But voluntary disclosure isn’t as important as it once was. But commodifying data to inform investment decisions? That’ll work. 🧵
