Fighting for climate action, and challenging anti-science propaganda, disinformation, and misinformation.

A few years ago, prior to Australia’s ‘Black Summer’, I began capturing extreme events as I became aware of them escalating to a frequency of becoming annual events - some type of disaster of unprecedented scale occurring somewhere where such an event was previously unheard of. 🧵

But what’s causing the climate to change in the first place? I’ve read down the thread and nobody seems to know 🤷. Does it have something to do with people not recycling their yogurt pots? Is it cows? Because if we knew what the main cause was we could maybe do something about it 🤷.

ANCAP’s crash tests are proving electric cars to be the safest vehicles in Australia

Battery-powered models make up 6 / 7 strongest crash test performers

Surprise: highly flammable liquids (petrol and diesel) in ICE are much more likely to catch fire than electric cars

I start all of my presentations with this gif.
Spiralling global temperatures (1850-2025)

The last 3 years really jump out, rather like 2015-6 did when we first produced this graphic back then. Now, 2015-6 looks rather cool...

I still remember when Istanbul had weeks of snow (yes, Istanbul!). When summers over 30°C felt alarming. When droughts and fires along the Aegean coast were exceptional enough to dominate the news for days. We normalize too quickly!

“Uruguay did what most nations still call impossible: it built a power grid that runs almost entirely on renewables—at half the cost of fossil fuels. The physicist who led that transformation says the same playbook could work anywhere—if governments have the courage to change the rules.”
Uruguay’s Renewable Charge: A Small Nation, A Big Lesson For The World
Uruguay built a power grid that runs 99% on renewables—at half the cost of fossil fuels. Here’s how its bold energy overhaul became a global model.

Breaking News!
Code Yikes!

In the depths of La Nina the planet is still breaking temperature records: January 6th was the hottest on record for the date since 1940, at 1.65°C over the 1850-1900 pre-industrial baseline.

The next El Nino is going to be interesting.

The corporate fascist playbook precedes ‘Reboot’ & ‘Project 2025’ by more than half a century. It’s ludicrous to think that halfwits like Yarvin, Thiel, Vance, Trump, Musk, & their idiotic bumbling cronies are even the slightest bit capable of anything original

Just goes to show how little it could take to trigger WWIII. Closer to it now than at any other time in my 62.5 years is my reckoning.
