I’m a scientist who studies how climate change impacts our lives and the places we love.

Most of us are worried, but many feel stuck on what to do. If that's the way you feel, check out this list below!

We can’t fix it alone, but I know we can together. 💚
A list of the most effective ways an individual can catalyze change at the scale we need to effectively tackle climate change, based on social science.

Here's a more technical yet still quite accessible overview of the climate.
Of particular note that even though we set a record for solar/wind last year, we also set the record for burning fossil fuels. Which we need to stop immediately, yet keep doing anyway. Which is Very Bad.
The 2025 state of the climate report: a planet on the brink
We are hurtling toward climate chaos. The planet's vital signs are flashing red. The consequences of human-driven alterations of the climate are no longer

As a climate scientist online, I get plenty of troll comments. But every now and then, there's a message that feels like a little beam of sunlight. That makes it all worthwhile. ☀️😄☀️
A screenshot of a LinkedIn comment that reads, "Ten or so years ago I kept reading Katherine Hayhoe, the climate scientist, until I saw she was coming to speak in Toronto. I just had to hear her in real life. So, I drove the 3 hours from Rochester NY, alone on a cold winter evening, to see the scientist that changed my mind about climate change."

The new Global Fire Emissions Database (GFED5, 2002–2022) shows that at the global scale 1) by far, most area burned are grasslands; 2) area burned is declining; & 3) fuel consumption is increasing: ie, fires are increasing in forests & encroached grasslands.

Our latest study found a notable lack of news reporting on the human health relevance of climate change in the world’s three leading carbon-emitting nations. Over the past decade, only 8% of climate-related articles included any mention of human health.

The end of coal in California ⬇️
dvschroeder.bsky.social Dan Schroeder @dvschroeder.bsky.social · 4d
Something to be thankful for!

Utah's largest coal-fired power plant—the Intermountain Power Project, located in the west desert near Delta and serving southern California—stopped burning coal at mid-day on Wednesday, just in time for Thanksgiving. 🔌💡
Screen capture from the EIA Hourly Electric Grid Monitor (https://www.eia.gov/electricity/gridmonitor/dashboard/electric_overview/balancing_authority/LDWP) showing a chart of hourly generation by energy source within the Los Angeles Department of Water and Power balancing authority, from November 21-27. The data indicate that natural gas is almost always the largest source, with significant contributions from solar, wind, and coal. The curve for coal fluctuates in the approximate range of 350 to 630 megawatts up to mid-day on Wednesday, November 26, when it abruptly drops to zero. It remains at zero through all of November 27, Thanksgiving Day.

From the above, you can see how short the list is of investments that have been made. They could all fit inside a single PragerU organization with ample room to spare: and PU's just one of the dozens of extremely well funded disinfo and propaganda efforts that exist.
Why critics are alarmed about the influence of PragerU's educational videos
The rise of edutainment, the integration of entertainment with educational content, has become a billion-dollar industry. The conservative PragerU has positioned itself as a major player in this space...

* Being a scientist of course I must caveat the statement above:

NYT's 50 states, 50 fixes series is great.

I know a single climate marketing org that has been very successful at fundraising: but that's just one piece of what's needed.

I once (in 25 years) got a small grant to support my comms.

Precisely. And, as George Lakoff explains in detail and my own personal experience heavily validates, those with money who do say they care about climate change will not invest in climate communication and tackling misinformation. AT ALL.

Join me and my @texastech.bsky.social Climate Center colleagues for a breakdown of all things COP30, in an hour.

Nick is an ecologist, Ting is an engineer, Bryan is a humanities scholar, and you know me: so it should be a great discussion.

We’ve always had floods – but as the world warms, they’re becoming more intense and more severe.

We’re all in harms way – but those who don’t have a safe place to live, or can’t take food and water for granted, are always most vulnerable.

oh my goodness I love your topic! Do you have a short essay/summary/highlight piece I could read? I had a chapter about this in my book Saving Us a few years ago and I still run into this claim on a very regular basis.

Unfortunately that’s the symptom rather than the cause. The cause is solution aversion and identity politics.

Imagine the hole in Alberta’s budget when the price & demand for oil is in long-term decline in 2030s as a result of the energy transition and increased demand for clean energy. Not nostalgia for the past, it’s about winning the future. Just economics, folks.
Alberta faces $6.4-billion deficit as falling oil prices and trade troubles take toll
This year’s budget represents a massive multibillion-dollar swing from an $8.3-billion surplus last year
