‘Risk’ analyses largely ignore the dangers of the climate crisis. Unless we wake up to them, they will soon outweigh all others

Per the paper:

The GMST-CO2 relationship indicates a notably constant “apparent” Earth system sensitivity (i.e., the temperature response to a doubling of CO2, including fast and slow feedbacks) of ∼8°C, with no detectable dependence on whether the climate is warm or cold.

This is a very very big deal if it turns out to be valid in the present world.

I'll note that much of what is in this article has previously been published in Icelandic, but that's not very accessible to most of the world.

"Summer has increased by an average of 36 days across Spain over the last 50 years.

Spain is slipping into a desert climate, according to a new study into the relationship between global heating and drought.

The Mediterranean country is clearly on the frontlines of climate change in Europe. Now researchers at the Universitat Politècnica de Catalunya (UPC) in Barcelona have delved deeper into its climate vitals.

By 2050, they predict that rainfall will decrease by up to 20 per cent compared to current levels. This would tip Spain from a temperate Mediterranean climate into a steppe- or even desert-like one, as per the Köppen system which divides the world into five different climate zones based on plant growth.

“The warming process resulting from climate change has been very pronounced in mainland Spain and the Balearic Islands, representing a true hotspot,” the researchers write..."

"The Bureau of Meteorology is shifting the way it communicates about climate phenomena such as El Niño and La Niña, because global heating is making predictions based on the past less reliable.

This week the bureau kept the country on a “La Niña watch” and said if the climate system in the Pacific does develop, it’s likely to be short-lived and weak.

Historically, La Niña events – where warmer waters gather to the north of Australia – have been associated with cooler and wetter conditions from across north-western Australia to the south-east. El Niño events are often warmer and drier.

But Dr Karl Braganza, national manager of climate services at the bureau, said climate change and the amount of heat being added to the oceans made those old relationships less reliable.

Climate change may not have “broken” them, he said, “but the number of times when the climate is inconsistent with what we saw in the past will only increase”...

Just 0.7% of the world’s land surface is home to one-third of the world’s most threatened and unique four-legged animals, a recent study has found. In the vast evolutionary tree of life, some animals, like rats, have many closely related species that are at no immediate risk of extinction. But others, like the red panda […]

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
