PG&E’s Senior Director of Meteorology Operations and Fire Science Scott Strenfel speaking at #OSSTahoe moving the utility into an era of public safety power shutoffs since the 2017 North Bay fires and more targeted shutoffs, HD cams/AI, fire threat index modeling and down conductor detection.

@WCraigFugate - former FEMA Administrator at #OSSTahoe speaking about how the insurance model, disaster policy, etc is breaking down due to more extreme storms from climate change and how FEMA was not designed by Congress to make victims whole, esp. in this climate changed era. 1/

See more extremes in less than a year: Summer temps reaching all time records in Canada (121 F in Lytton, BC) followed by destructive wildfires in the same area, then extreme flooding in Vancouver later in Fall 2021 #OSSTahoe 1/27/2025

Insurance models built on past weather data/100 yr events cannot keep up with today’s “uninsurable risk” - ex: wildfires in California, catastrophic flooding increasing in frequency and intensity due to climate change #OSSTahoe 1/27/2025
Former FEMA Director W. Craig Fugate speaking at #OSSTahoe on the roles of FEMA moving forward navigating extreme weather events, including the most uninsured risk - flooding as climate induced impacts increase. 1/27/2025

Also more methane released from natural sources (cattle) than the oil and gas industry … re-purposing of methane release can lead to additional energy sources in the future (PG&E working a similar project in Solano County) #OSSTahoe 1/27/2025
Solutions: fixing / upgrading systems for fewer methanr emissions, lowering risk of failure w/ the Cincinnati example here and addressing landfill emissions #OSSTahoe 1/27/2025

PG&E has added 1,582 weather stations to boost weather model accuracy including 1,400 machine learning (AI) models deployed. Strenfel - fuel conditions are most impactful in a warming climate - the need for fuel reduction to reduce wildfire intensity #OSSTahoe 1/28/2025

Methane leakage imaged via special optics can help identify point sources of methane emissions (plume invisible to naked eye). New generation satellites providing better mapping of methane emissions (Carbon mapper) #OSSTahoe 1/27/2025

View of the Clay Fire that broke out January 21st in Southern California from my Southwest flight on approach to San Diego. Short layover before continuing onto Reno. Absolutely heartbreaking to see from above.

On the #DixieFire, radar shows bookend vortices develop as fire ramps up intensity/spread, including an area w/ “EF-1” estimated strength (nearly 100 mph) but with fire. This includes the “hook echoes” on radar #OSSTahoe 1/28/2025 #CAwx

@gcarbonproject Rob Jackson at #OSSTahoe talking about Methane’s share of Climate heating. Much of excess methane is from Ag (cow burps) and biomass, but the portion that comes from fossil gas is not from “burning” it’s from leaks in the extraction/ supply chain. Rob’s team… 1/
