This summer I'm travelling from Edinburgh to Marseille by train. The return fare for the UK leg is £245. The return fare Calais to Marseille is £75. The UK journey is 8hrs each way. The French journey is 6hrs for twice the distance.

If you stop in Paris, I'll be glad to meet you over coffee.

'Fraid we're just zipping by this time Svarty. Definitely looking at an extended visit to Paris some time soon though. I'll keep you abreat of developments.

[Svartalf]

alright, I thought it would be so, but would not care to be caught lacking in hospitality

Great, more giant bushfires for us here in Australia. At least I won't get flooded out for the next few years.

BC, Alberta and Saskatchewan have had record or near record wildfires this year. Also, BC and Ottawa areas have been flooded.

And you had the killer heatwave and fires last year.

'Limiting global warming to 1.5°C would save billions from dangerously hot climate'

Current climate policies will leave more than a fifth of humanity exposed to dangerously hot temperatures by 2100, new research suggests. The paper, published in the journal Nature Sustainability, is entitled "Quantifying the Human Cost of Global Warming."

Despite the Paris Agreement pledge to keep global warming well below 2°C (compared to pre-industrial levels), current policies are projected to result in 2.7°C warming by the end of the century.

The new study, led by researchers at the Global Systems Institute, University of Exeter, associated with the Earth Commission, and Nanjing University, assessed what this would mean for the number of people living outside the "climate niche" in which our species has thrived.

It says about 60 million people are already exposed to dangerous heat (average temperature of 29°C or higher).

And 2 billion—22% of the projected end-of-century population—would be exposed to this at 2.7°C of global warming.

The paper highlights the "huge potential" for decisive climate policy to limit the human costs and inequities of climate change.

Limiting warming to 1.5°C would leave 5% exposed—saving a sixth of humanity from dangerous heat compared to 2.7°C of warming.

The study also finds that the lifetime emissions of 3.5 average global citizens today—or just 1.2 U.S. citizens—expose one future person to dangerous heat. This highlights the inequity of climate crisis, as these future heat-exposed people will live in places where emissions today are around half of the global average.

In "worst-case scenarios" of 3.6°C or even 4.4°C global warming, half of the world's population could be left outside the climate niche, posing what the researchers call an "existential risk."

"The costs of global warming are often expressed in financial terms, but our study highlights the phenomenal human cost of failing to tackle the climate emergency," said Professor Tim Lenton, director of the Global Systems Institute at the University of Exeter.

The paper is open access:

'Quantifying the human cost of global warming'

Abstract:

The costs of climate change are often estimated in monetary terms, but this raises ethical issues. Here we express them in terms of numbers of people left outside the ‘human climate niche’—defined as the historically highly conserved distribution of relative human population density with respect to mean annual temperature. We show that climate change has already put ~9% of people (>600 million) outside this niche. By end-of-century (2080–2100), current policies leading to around 2.7 °C global warming could leave one-third (22–39%) of people outside the niche. Reducing global warming from 2.7 to 1.5 °C results in a ~5-fold decrease in the population exposed to unprecedented heat (mean annual temperature ≥29 °C). The lifetime emissions of ~3.5 global average citizens today (or ~1.2 average US citizens) expose one future person to unprecedented heat by end-of-century. That person comes from a place where emissions today are around half of the global average. These results highlight the need for more decisive policy action to limit the human costs and inequities of climate change.

As conservatives continue to stress that implementing plans to reduce the causes of record hot temperatures, wildfires, and pollution infringes upon their liberties, The Onion asked conservatives to explain how climate hysteria violates their freedom, and this is what they said.

“I just think it’s crazy to get worked up about anything that isn’t a man in a dress.”

Polly Hidalgo, Pediatric Physician
“We need to turn down the volume on the climate hysteria. Turn it down. It is too loud...the volume. The volume must be at, 80, 90, the loud volume. It is hurting my ears, how hysterical it is. It is like a jackhammer in my ears, in my mouth, in my nostrils. My nostrils are filled with loud noises, they are spilling into my ears. I can’t breathe...I can’t breathe, I am suffocating. I am choking on their loud volume, their harsh grating noises, their acrid and noxious foul-tasting sour noises that are burning me, burning me alive...”
