Sea level much higher than assumed in most coastal hazard assessments - Nature Meta-analyses on a global scale show that the measured coastal mean sea level is higher than assumed in most coastal hazard assessments.

In a groundbreaking new study released in @Nature.com, Dutch scientists find that today’s sea level is much higher than assumed in most coastal hazard assessments, with the most significant errors in Southeast Asia and the Indo-Pacific regions.

Experts Call For N95s Over Surgical Masks As Flu, Covid Viruses Spread World Health Network experts urge WHO to make N95, KN95, or FFP2 respirators the standard for protection for healthcare workers, not inferior surgical masks.

Experts Call For N95s Over Surgical Masks As Flu, Covid Viruses Spread, @DrJudyStone writes in @forbes
"WHN sent a letter to the WHO urging them to declare respirators as the default protection for healthcare workers, rather than surgical masks."

Face masks ‘inadequate’ and should be swapped for respirators, WHO is advised Experts are urging guideline changes on what health professionals should wear to protect against flu-like illnesses including Covid

Our letter to WHO, signed by over 2,300, calls for respirator use in healthcare to protect patients and staff.

Two Years to 1.7°C: the “Prediction Game” We Can’t Afford to Lose Australia’s sweltering through another early-summer heatwave, and I’m trying to decide whether to write about the weather outside my window - or the bigger climate system we’re reengineering on this p...

This week, Professor James Hansen and colleagues published projections that the global temperature record could reach +1.7°C by 2027.
And if that number lands in your gut the way it landed in mine, good. It should.

Australia has so much solar that it's offering everyone free electricity Australia's extensive solar power penetration makes so much energy that the government wants to offer free electricity at peak hours.

Australia has so much electricity from solar power that it is going to start offering free electricity to everyone for at least three hours during the day as the wholesale price of power goes negative

"Do doctors really know what they are talking about when they tell us vaccines are safe? Should we take climate experts at their word when they warn us about the perils of global warming? Why should we trust science when our own politicians don’t?" @naomioreskes.bsky.social provides some answers

As California burns, new research shows smoke is wildfire’s silent killer The official death count from the Palisades and Eaton fires was 30 — the real number may be 15 times higher.

A growing body of research is reinforcing the knowledge that wildfire smoke is much more than an inconvenience — in fact, it’s actually killing far more people than the flames themselves. grist.org/health/calif...

Fluid dynamical pathways of airborne transmission while waiting in a line Waiting and walking in lines (queues) can create unexpected air currents that can either heighten or suppress infection risks.

😷 Airborne risk in queues

A new study found that when people wait in line, breath clouds can linger due to hidden air currents, especially at certain temperatures. Distance alone may not cut it.

Climate change is a collective-risk dilemma: we pay a personal cost, unsure others will act, but everyone shares the benefits.

New study finds that even under added risks, people still cooperate when goals are clear and impact is real.

Many followers of NCSE have a similar story, so perhaps some of you can relate to Ella Al-Shamahi, a former devout Muslim who is now a paleoanthropologist. In this article, she reflects on coming to terms with her understanding of evolution, and the struggle of leaving her religious community.

UN Secretary‑General António Guterres:

"Countries that cling to fossil fuels are not protecting their economies – they are sabotaging them. Driving up costs. Undermining competitiveness. Locking-in stranded assets. And missing the greatest economic opportunity of the 21st century."
