French heatwave deaths estimated above 2,700
Carbon Brief published a new analysis estimating more than 2,700 heat-related deaths in France during the June 12-29 heatwave. The analysis says daily high temperatures averaged across France reached 36.9°C, 2.4°C above the previous June record, and heat-related mortality rose to nearly 300 deaths per day on June 24-25. Al Jazeera separately reported that the heatwave exposed unequal access to cooling in places such as Saint-Denis and worsened high-mountain risks around Chamonix.
Why it matters
The analysis converts an extreme European heat event into a quantified mortality signal, sharpening questions about heat adaptation, public health capacity and climate attribution.

Al Jazeera coverageWestern governors form transmission-expansion coalition
Heatmap reported that governors from 11 Western states signed a pact at the Western Governors’ Association annual meeting to coordinate regional grid planning and speed permitting through the Western Transmission Expansion Coalition. The states are Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, North Dakota, Oregon, Utah, Washington and Wyoming. A WestTEC study cited by Heatmap projects the region will need 12,600 miles of new transmission lines over the next decade at roughly $60 billion.
Why it matters
Transmission constraints are a major bottleneck for clean power deployment, load growth and grid reliability across the western United States.

Heatmap coverageSafe-harbored clean projects still face federal hurdles
Latitude Media’s Maeve Allsup reported that wind, solar and storage projects that began construction before the July 4 clean-energy tax-credit deadline now have four years to come online, but face unresolved federal risks. Jason Clark of Power Brief identified permitting, tariffs and foreign-entity-of-concern rules as the main hurdles; Wood Mackenzie estimated more than $121 billion in early-stage renewable projects could be affected by the administration’s permitting blockade. Court injunctions have paused several permitting changes, while Section 232 tariff moves and Treasury’s interim FEOC sourcing guidance could alter procurement economics and tax-credit eligibility.
Why it matters
Projects may have preserved access to tax credits, but policy uncertainty could still delay construction, raise costs or shift risk across developers, financiers and suppliers.

Forest carbon models may overestimate
Energies Media’s Kelly Lippke reported a Cornell study finding land-surface models may overestimate future forest carbon storage by up to 30% because heat and drought can slow tree growth even when photosynthesis continues.

Climate.gov backup goes independent
Grist’s Kate Yoder reported that former NOAA staff launched Climate.us to preserve and update Climate.gov-style explainers and visuals after federal staffing cuts and the shutdown of Climate.gov.
Still unclear
OPEN QUESTION
Can heat adaptation keep pace?
France’s estimated death toll suggests that even countries with post-2003 heat plans may face mortality spikes as European heat extremes outpace some model expectations.
OPEN QUESTION
Will policy uncertainty strand safe-harbored projects?
The four-year build window for tax-credit-qualified projects depends on permitting outcomes, tariff decisions and FEOC eligibility rules that remain unsettled.
