Future of the human climate niche
and
Quantifying the human cost of global warming

Future of the human climate niche
"All species have an environmental niche, and despite technological advances, humans are unlikely to be an exception. Here, we demonstrate that for millennia, human populations have resided in the same narrow part of the climatic envelope available on the globe, characterized by a major mode around ∼11 °C to 15 °C mean annual temperature (MAT). "
"We show that in a business-as-usual climate change scenario, the geographical position of this temperature niche is projected to shift more over the coming 50 y than it has moved since 6000 BP."
"Global warming will affect ecosystems as well as human health, livelihoods, food security, water supply, and economic growth in many ways."

Quantifying the human cost of global warming
"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."
"The worst-case scenarios of ~3.6 °C or even ~4.4 °C global warming could put half of the world population outside the historical climate niche, posing an existential risk"
"The ~2.7 °C global warming expected under current policies puts around a third of the world population outside the niche."

'Temperatures in [#Phoenix] have already topped 110°F for the last 12 consecutive days, nearing its all-time record of 18 consecutive days over 110°F, which was set in 1974. In the early morning hours Wednesday, Phoenix did break a notable record, when the all-time low temperature registered on July 12 only fell to 94°F."

Threw this together last night - #HighTemperatures yesterday. It'll come in handy as readings rise in the Southwest this weekend.

Love how the West has such huge variation via elevation etc. #python

"The 2019-2020 Australian wildfires demonstrated that compound climatic events – long-lasting record high temperatures combined with record low precipitation – can lead to unprecedented large-scale impacts. These fires affected 80% of the people living in Australia in some way".
