Handy visual of “life cycle” (i.e. manufacturing + installation + operation + decommissioning) of energy emissions of heat-trapping carbon dioxide equivalent (CO2e) based on NREL data with visual available at UCS. www.ucs.org/resources/be...

Original caption: “Comparison of as-published life cycle GHG emission estimates for electricity generation and electricity storage technologies. UCS/NREL data.” Each bar in the chart includes a black line for median value, darker hue color for Q2 to Q2 range and lighter hue color for minimum and maximum values. Biopower has a vastly larger range followed by coal, fossil gas and oil. The median values of Biopower, Photovoltaic, Geothermal, Hydropower, Wind, and Nuclear are slightly above the zero horizontal line, while Natural Gas, Oil and Coal are significantly above the zero horizontal line. Bar chart visual by Union of Concerned Scientists. Data source National Renewable Energy Lab.

Michela Biasutti, research professor @lamont.columbia.edu hosts hour 43 during 100-hr @wclivestream.bsky.social when Carly Phillips, scientist @ucs.org explains drivers of wildfires 🔥(see image ⬇️ with research findings by @climate-guy.bsky.social & @emilywilliams.bsky.social)

Screenshot image during ‪@wclivestream.bsky.social‬ livestream that includes 2 video images of the host, Michela Biasutti, research professor ‪@lamont.columbia.edu and presenter Dr. Carly Phillips, scientist
‪@ucs.org with slide image with the following words “Drivers of current wildfire situation: - Loss of burning by indigenous communities – Widespread fire suppression – Land management – Human development – Fossil fueled climate change.” Displayed to the right is = an x-y plot of “Cumulative Acres of Forest Fire Area” vs year (1985-2015) with title “Climate change is a major driver behind the growth of western forest fires.” The plot includes a light blue area labeled “Acres burned without climate change” and a darker blue area labeled “Additional acres burned with climate change.” At the bottom includes image credit to @ucs.org based on “Abatzaglou & Williams 2016, Impact of anthropogenic climate change on wildfire across western US Forests, PNAS” also at ‪@climate-guy.bsky.social‬ & @emilywilliams.bsky.social‬

Casey Ivanovich @ccivanovich.bsky.social shared during @wclivestream.bsky.social the factors influencing dangerous extreme heat events plus ‬a public communication tip for conveying the difference between humid and dry heat extremes – “sticky” vs “crispy”

Schematic presented by Casey Ivanovich @ccivanovich.bsky.social during @wclivestream.bsky on May 28, 2025. "Explore how the land surface influences the tradeoffs between temperature and moisture to affect both dry and humid heat extremes." Schematics has the following labels next to images representing each: "solar insolation, large-scale circulation, precipitation, cloudiness, advection, urbanization, evapotranspiration, deforestation/land use change, proximity to water bodies, and irrigation."Text for questions also displayed, " How is this linked to heat seasonality?" and "How are humans altering these balances?"
