Any political party spreading lies about voter fraud as a pretext to make it harder for every one to vote is sending a clear message: they can't win on their ideas alone.

Remember this.

Headline from The Telegraph of an idiotic piece by Matt Ridley: CO2 is simply not a danger to human health, and it's actively good for crops.

Human Rights Watch warns US heading to 'authoritarianism' Donald Trump's return to the White House has intensified a 'downward spiral' on human rights, the New York-based advocacy and research group said in its annual report.

I've never been tear-gassed. It's not normal

When an environment and education journalist is not only saying "I got tear gassed and so did children" but is comparing it with their previous experiences of being tear-gassed, you know stuff is going seriously and systematically wrong

As far as Nigel Farage is concerned, let us remind ourselves that he said if we left 
the EU it would be Β£350 million a week for the NHS - that didn’t happen.

He said if we left the EU there would be less red tape for trading into Europe - try telling that to any business that is trading into Europe.

He said if we left the EU regular migration would go down - it quadrupled under the Boris wave.

The Brexit campaign was fuelled by misinformation, and new polls have found that the majority of Brits want to reverse it. We must continue to fix our relationship with Europe, and rekindle our ties with the biggest free market in the world.

In the middle of everything, Minneapolis is holding the Great Nothern Festival, which celebrates our winters, our culture, and local climate solutions.

The amazing Dr. Ayana Johnson @ayanaeliza.bsky.social is the keynote speaker tonight, along with many local climate heroes.

Proud of Minnesota!

The big question is whether this will cause journalists working in mainstream for-profit corporate media to

(a) Become even more obsequious,

or

(b) Become defenders of the civil liberties, rule of law, and democratic institutions upon which their profession depends.

Opinion | Guan Heng Gets U.S. Asylum A judge grants refuge to a worthy dissident, no thanks to DHS.

Guan Heng went to Xinjiang to photograph the detention camps where the Chinese Communist Party imprisons Uyghurs. He fled China via Hong Kong, Ecuador, and the Bahamas, reaching Florida on an inflatable boat. The US was considering his asylum case when ICE arrested him. DHS has not released him.

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good.

As we breach 1.5 Β°C, we must replace temperature limits with clean-energy targets Nature - Actionable goals are needed to guide the world towards what needs to happen most quickly: shifting economies to clean energy sources.

As the world quickly approaches 1.5C, researchers have a call in Nature to rethink the utility of temperature targets – and to potentially replace them with more actionable and precise targets around clean energy:

Minnesota National Guard members have arrived at a federal building and were directed to distribute donuts, coffee, and hot chocolate to anti-ICE protesters. Guard members were issued reflective vests so they would not be mistaken for federal agents.

The guidance is dead - long live the guidance Some thoughts on the Road Safety Strategy and implementing 20mph limits

UK Gov could reduce killed and serious injuries on UK roads by 30,000 over the next decade. It just needs to facilitate the same initiative that already exists in one half of the UK for the other half. And its a key component of the Road Safety Strategy it has just announced.

Climate scientists are also obsessed with Greenland, not because of the Mercator projection, but because the melting of the Greenland ice sheet is going to raise sea levels significantly, change ocean circulation, and be generally very bad for humanity.

Geopolitical shocks can - and must - be an opportunity for Europe.

The seismic shift underway makes it both possible & necessary to build a new European independence.

From security to the economy.
From defence to democracy.

Europe is gathering speed.

A fast moving coronal mass ejection (CME) means the northern lights may be visible overnight, and perhaps on Tuesday night too

The arrival time of the CME is uncertain, but aurora sightings are possible in northern Britain and perhaps in southern areas depending on cloud cover.
