Yes - they are the 11%. Wasting our time and energy on them accomplishes little. It’s 90% we need to - and can - move.

We surveyed 210 of the most active climate communicators across the US and Canada. Only one pair reported both collaborating with each other AND sharing information with each other. Key results below. Read the full report here: talkingclimate.com/landscape-as...

A screenshot of the top five results from our US/Canada landscape survey of climate communicators - they tend to work alone, funding is scarce, they're helping people understand & act, they're mostly talking to insiders and they need connection.

Art can often communicate what science can’t. These amazing mosaics—Dissolution & Dust—by Marcela Paz Luna Rossel were inspired by scientist Sasha Gershunov’s work on flood & drought in CA. Sasha took this picture of me and his Very Good Dog when I was visiting @scrippsocean.bsky.social today.

I’ve been prioritizing virtual talks for well over a decade now, long before things like Zoom, teams, or meet even existed. Back then, many were dubious (but I won them over). If any are still in doubt, tho, let me point out that virtuals have much higher chance of a Dr Evil cameo 😸 nuff said!

Greetings, Katharine. Your efforts to combat climate change are truly commendable. But you have been misled as to the cause of Global Warming. Modern cosmology is wrong about galaxy evolution; and their error places Mankind in great peril.
Unlike the Big Bang theory, what I am about to tell you is actually supported by visual evidence.
Our Sun, like all the other stars in the Milky Way, has not been orbiting the galactic center for 5 billion years, as we have been led to believe. Instead, our Sun formed on the outer edge of the Milky Way; and, like all the stars in all the spiral galaxies, has spent its existence spiraling INTO the galactic center. Every spiral galaxy clearly shows this motion.

This implies that the centers of galaxies are eternal; therefore there was no Big Bang, and the Universe is not expanding.
Matter continuously forms on the outer edges of all spiral galaxies, and matter is continually recycled in the fiery galactic centers. This is why all the Milky Way stars travel at the same speed, not because of Dark Matter.
Since the centers eject matter, by definition they cannot be black holes.
Most importantly, this implies that Global Warming is not anthropogenic, it's a direct result of increasing proximity to the center of the Milky Way. We don't have another 5 billion years left - we are at the end of the galactic ride.
At 220 km/sec, or 491,832 mph, we travel 11.8 million miles closer to our extinction every day; and the whole world is blissfully unaware. This equates to 1.08 billion miles closer each season.

Global Warming is going to increase exponentially, as the polar ice caps shrivel and vanish.
Sea levels rising isn't the threat we face. The entire ocean is rising up. Once the polar ice caps vanish, so will all life on Earth.
So you see, there is very little we can do to prevent further warming of the planet. We are ignorant spectators in a cosmic dance that nobody is even aware of.
Believe what you want to believe, and do what you want to do. But my theory explains everything that the Standard Model of Cosmology cannot, and it's supported by visual evidence. One hundred years of science trying to prove Einstein correct may cost Mankind its very existence.
Record flooding around the globe indicates that our time is running short.
If you are picking up what I am throwing down, please visit my website and read my solution to save humanity.
Time is not our ally; whether anyone believes me or not...

We have a winner for the absolute worse headline of the day! No one can prevent global warming -- because it's already happening But we absolutely can limit it by reducing our emissions. And when it comes to limiting it, there is no magic threshold. Not 1.5, not 2. Every tenth of a degree matters.

Conclusions of the IPCC 1.5C report - every bit of warming matters.

Exhibit B on the "looking for an argument, not an answer" list.

A post from an anonymous account that ignores the thread above and instead asks a bunch more questions. This is a trolling technique known as "sea lioning". You can see, as I said above, they are doing their best to start an argument rather than get answers.

Today, 3 Bluesky accounts told me humans aren't causing climate change. This one was legit the funniest excuse yet. Each time, I give them a reference that answers their objection. When they refuse to read it, I block. Why? Because they're not looking for answers; they're looking for an argument.

Every disaster has multiple factors. Vulnerability, exposure, and the hazard itself all interact to create a disaster – that is well known. In fact, I teach an entire graduate class based on this diagram! Climate change is loading the dice against us, increasing both the risks and the danger.

The classic vulnerability, hazard, and exposure diagram that explains how risk is a function of all three. Original source is IPCC SRES 2012.

All the projections I've ever worked with predicted an acceleration in the rate of global warming if we continued to increase our emissions. The fact that so many people are shocked about this honestly surprises me. I guess no one ever reads things like the IPCC or National Climate Assessment 🤷‍♀️

A figure I made for NCA4 about 10 years ago. The world was tracking the RCP8.5 scenario equivalent emissions through about 2020, and that's the temperature change we're seeing today.
