The lessons from Brazil and Serbia? Don't concede one inch of ground to the far right. Don't appease. Don't triangulate. Don't grovel. Don't say they have "legitimate concerns". Mobilise your base, and fight them with all the democratic means at your disposal.

Climate change has stopped the next Ice Age For thousands of years, Earth’s orbital cycles favoured cooler northern summers, the kind of conditions that help ice sheets grow. Then GHG emissions changed the balance reversing ~2,000 years of ice-sheet expansion. www.science.org/doi/10.1126/...

Danny Tommo's 'patriot platform' vigilantes were refused service in The George Inn, Portsmouth. They demanded to know why, despite the fact they do not have to be given a reason. Always make bigots feel unwelcome. Show the pub some love for doing the right thing. Things you love to see ✊❤️

Unless you work in strategic defence planning you probably won't realise what horror this truly means. Even at a mid-century global average of 1.8°C it means enough pressure on governance systems and authorities to 'collapse' states, magnify civil violence and fuel many more armed conflicts.

Again, this doesn’t mean +2.8°C everywhere. Land warms faster than ocean; the Arctic much faster than the global mean. Some regions will see far greater shifts than others. One global number....with radically different local realities. www.independent.co.uk/climate-chan...

It should be simple: 👉 Warm Homes Plan: projected £1bn annual bill savings, 50,000 jobs. 👉 Rosebank: around 1,100 jobs. Insulate homes. Cut bills. Create jobs. Reduce fossil fuel dependence. Why not invest in warmth, not more oil? www.theguardian.com/environment/...

Will this year's record-shattering El Niño event be the strongest in a millennium? In a new piece over at The Climate Brink I review the paleoclimate literature from tree rings and corals and argue that may well turn out to be the case:

theclimatebrink.comThe strongest El Niño in a thousand years?Tree rings and corals both put the biggest modern El Niños at or near the top of the past millennium, and this year’s event is on track to land well above them.

Interesting We tend to think of “climate tipping points” as one big research area. They’re not. Attention is massively skewed: Greenland has 1000's of papers, while some tipping elements have <150. What risks are we missing simply because they’re harder to study? www.pnas.org/doi/10.1073/...

Flying is officially on course to account for *almost all* the UK's carbon dioxide emissions by 2050. Heathrow expansion alone would cause more carbon emissions by 2054 than *any other sector of the economy*. So why is it being contemplated? My column. www.theguardian.com/commentisfre...

theguardian.comThe expansion of Heathrow would be an expensive disaster for Britain and the world. Burnham needs to block it | George MonbiotA third runway would fly in the face of reason.

The ability to pour hundreds of millions of pounds into a loss-making TV channel, bent on wrenching British politics sharply to the right, is yet another of the ways in which extreme wealth is trying to remake UK democracy. It needs to be part of any serious conversation about political funding.
