my takeaway from climate week nyc is that "climate storytelling" is a little too much "we must reimagine our deepest souls in relationship to mother nature and the moral abyss of the polycrisis into which we must now stare" and not enough "ok but get a heat pump"

This newly released visualization showing the progression of the Palisades and Eaton fires was the last visualization produced by the SVS's Cindy Starr after an incredible 37 year career.

Sorry that it is hard to find. It is listed in the dataset section, but we will make sure it gets bumped up to the main text as well.

NASA is more than rockets and moonwalks. NASA is behind much of our everyday technology. From space discovery, to Air Jordans, to CAT scans, NASA has played a role. We get it all on less than a penny of every federal dollar. Now their science may be gutted by 50%.

A few tips:

1: Open up your aperture as much as you can for more bokeh. Faster lenses are better.

2: Make a mark on your focus ring + lens (I use two narrow strips of masking tape) so you can quickly and repeatedly hit your in-focus point.

“I personally was pretty surprised, actually, at how efficient the government was,” Sahil Lavingia told NPR's Juana Summers.

Former DOGE engineer says federal waste and fraud were 'relatively nonexistent'

NPR's Juana Summers talks with Sahil Lavingia, who worked for the Department of Government Efficiency as a software engineer assigned to the Department of Veterans Affairs, about his experience.

I get annoyed at the narrative that all the awareness and work on climate change hasn't done anything. Yes, global CO₂ emissions indeed continue to climb, but we don't know the counterfactual. When I was in grad school, we were on track for 5°C of warming. Now it's below 3°C. That's progress.

A line chart titled “Annual CO₂ emissions” shows the global carbon dioxide emissions from fossil fuels and industry from 1950 to 2023. The y-axis represents emissions in billions of tonnes (t), ranging from 0 to 40 billion t. The x-axis covers the years from 1950 to 2023.

The chart presents a steady increase in emissions from approximately 5 billion tonnes in 1950 to over 36 billion tonnes in 2023. Key features include:

A consistent upward trend from 1950 through the early 1970s.

A brief plateau and dip around 1980–1983.

A strong growth trend resuming in the late 1980s.

A sharp increase during the 2000s.

A slight drop around 2008–2009, likely due to the global financial crisis.

A major dip in 2020, attributed to the COVID-19 pandemic.

A rapid rebound in emissions after 2020, continuing the upward trend to a new high in 2023.

A blue line labeled “World” traces these changes over time.

Below the chart, the data source is listed as the Global Carbon Budget (2024), and the graphic is credited to OurWorldInData.org with a Creative Commons license (CC BY). A footnote explains that the data includes emissions from coal, oil, gas, flaring, cement, and steel, but excludes land-use changes such as deforestation.

Let’s make today (May 10) Magnetosphere Appreciation Day!

A year ago today we had that huge aurora display, caused by the most powerful geomagnetic storm experienced in decades.

Lovely visualisations by NASA SVS/NASA DRIVE science centre on how our atmosphere and magnetosphere responded.

As summer in the Northern Hemisphere approaches, it is important to keep in mind how temperatures are changing 🌡️

Shifting distribution to the right ➡️ increasing societal risks from extreme heat

The driver? Humans... The burning of fossil fuels
