It's not often you can pinpoint real, positive change a journalist has caused. But as Turkmeni sources state, @dpcarrington.bsky.social's persistent and probing coverage of this issue has been critical to a change of policy, with massive implications.

Wow, almost 1C hotter than prior El Niños 😵😣 Bracing for more heatwaves on land and sea, fires, coral reef bleaching, and flash floods to come. Resilience and adaptive capacity will be severely strained.

An economist friend passes along this graph of energy costs. He says, "Given this history, it is more than a little ironic that renewable energy is derided by fossil-fuel proponents as 'unreliable.'”
Chart of relative energy costs since 2010 shows a steady decline in wind and solar vs wild oscillations in the price of oil due to geopolitical events like the current war in Iran.

As I say here, there is no scientific justification to revoke the engagement finding. In fact, over the last 15+ yrs, the evidence of how climate change affects our health has only grown. Higher risk of allergies, dementia, fertility, heart disease, and death: that’s what’s on the line. @nature.org

🔍#Biodiversity. Water. Food. Health. #ClimateChange. All of them interact and intersect but how? Check this new graphic from the @ipbes.net #Nexus Assessment and explore the interactions among the nexus elements. Access the Report: www.ipbes.net/nexus/media-...
A two-part infographic showing relationships between five nexus elements: biodiversity, water, food, health, and climate.

Part A shows projected future impacts across six different nexus archetypes, ranging from "Nature-oriented nexus" to "Nature overexploitation." Impacts are indicated using blue upward arrows (positive), red downward arrows (negative), and wavy lines (variable).

Part B displays six network diagrams showing interactions among the nexus elements. Each diagram represents a different archetype, using circles with icons for each element. Arrows between elements show relationships:

Blue arrows indicate positive influences
Red arrows indicate negative influences
Different arrow thicknesses show magnitude (high, moderate, low)
The diagrams progressively show how relationships between elements change from balanced and positive interactions in the "Nature-oriented nexus" to predominantly negative interactions in the "Nature overexploitation" scenario.

The visualization demonstrates how different management approaches affect the relationships between environmental, health, and climate factors.

Air pollution from fossil fuels causes at least 15% of deaths in the U.S., also heart disease, strokes, dementia, preterm birth, low birth weight, asthma and COPD. It reduces crop yields and work productivity, and damages GDP. There are lots of reasons to use clean energy, including health.
