Trees and land absorbed almost no carbon dioxide (CO2) last year, and scientists are struggling to work out why.

Carbon sinks, such as forests, oceans and soils, are an essential part of regulating the Earth’s climate. Through natural processes, these land and ocean masses absorb almost half of all human carbon emissions from the atmosphere.

But preliminary findings for 2023 – the hottest year ever recorded on Earth – have found that the amount of carbon absorbed by forests, plants, and soil has temporarily collapsed.

This was completely unexpected, and therefore not something factored into most predictions and calculations about how quickly the Earth will heat up as a result of climate change. The breakdown of the land carbon sink could be temporary, but if it isn’t, this will drastically increase the rate of global heating.

It will be impossible for the world to reach net zero without carbon sinks, because there is simply no human technology that can absorb carbon on the same scale as the forests, grasslands, peat bogs, and oceans of the world.

There is no sign of the transition away from burning fossil fuels that was pledged by the world’s nations a year ago, with 2024 on track to set another new record for global carbon emissions.

The new data comes from the Global Carbon Budget project, a collaboration of more than 100 experts led by Prof Pierre Friedlingstein, at the University of Exeter, UK, who said: “The impacts of climate change are becoming increasingly dramatic, yet we still see no sign that burning of fossil fuels has peaked. Time is running out and world leaders meeting at Cop29 must bring about rapid and deep cuts to fossil fuel emissions.”

Last week, we had a story about scientists who put bats on a treadmill. This week, a neuroscientist teaches rats to drive. And they love it!

From @ConversationUS: "We crafted our first rodent car from a plastic cereal container. After trial and error, my colleagues and I found that rats could learn to drive forward by grasping a small wire that acted like a gas pedal."

Putting vampire bats on treadmills reveals an unusual metabolism

A bat gym shows that vampires are more like some insects, burning amino acids from blood proteins rather than the carbs or fats other mammals rely on.

The Copernicus Climate Change Service, a European Union organization that monitors global heating, announced on Thursday that the year 2024 will be 1.5 degrees Celsius warmer than pre-industrial levels. That means humanity has passed a critical threshold established in 2015 in the Paris climate accord.

“After 10 months of 2024, it is now virtually certain that 2024 will be the warmest year on record and the first year of more than 1.5ºC above pre-industrial levels," Samantha Burgess, deputy director of the Copernicus Climate Change Service, said in a statement. "This marks a new milestone in global temperature records and should serve as a catalyst to raise ambition for the upcoming Climate Change Conference, COP29.”

The EU agency announced this moment as nations all over the world gather in the Azerbaijani city of Baku for the 29th Conference of the Parties. The ERA5 dataset found that global temperatures in 2024 were on average 1.55 degrees Celsius higher than the 1.48 degrees threshold measured in 2023. The report also noted climate change-fueled major weather events in 2024 such as torrential floods in Spain and rapidly melting Antarctic sea ice.

From @LiveScience: Emerging evidence suggests that plate tectonics may have begun much earlier than previously thought — and may be a big reason that our planet harbors life. Some scientists are now arguing that plate tectonics emerged very soon after Earth's formation — perhaps predating life itself. Read more: https://flip.it/9nLsjW

So, you'll recall in the late-1930s the UK & other countries (including the US) benefitted from a large scale exodus of scientists & other intellectuals... indeed, there's been a lot of recent work done on how these migrants informed & shaped British cultural institutions across the 30s/40s/50s & beyond.

Are we now going to see a similar exodus of US scientists & others, who will then have a similar galvanising effect on their new/host countries scientific & cultural lives?

Humans spend a lot of time moving in crowds. Matthew R. Francis and Maki Naro collaborate on this comic for @KnowableMag, which demonstrates how tools from fluid dynamics can help model crowd behavior and smooth the flow of crowds, potentially making us safer.

I somehow had never heard of cloud chambers before. With the help of condensing vapors at cool temperatures, you can see the actual paths of particles with your own eyes.

Not only can you see electrons, and protons, but you also see the interactions between particles. And cloud chambers have been used in physics since the 1920s, wild!

Not that any of us really want to read MORE bad news this week. But — this is the world we live in.

Turning away from it and closing our eyes does not change things. I believe it's important to know just where we stand and what we face so we can make the best choices in how we should live.

Also, note that this essay was published before this week's disastrous US election, which means that you can expect conditions warned about here to get even worse, sooner rather than later.
_______________________________________

In recent years, environmental warnings have become impossible to ignore. Humanity has pushed Earth far beyond its natural limits, launching it into a cascade of intertwined disasters that scientists now call the “polycrisis.” No longer a distant threat, this crisis is unfolding before us, destabilizing the foundations of ecosystems, economies, and communities worldwide.

While some hold out hope for a turnaround, the brutal truth is that we are too far gone. The trajectory is set, the damage done, and there is no miracle solution on the horizon. Our only option is to live through this polycrisis as best we can, facing an uncertain and increasingly harsh reality.

As temperatures climb, ecosystems crumble, and resource conflicts rise, it’s clear that our world will never be the same. For those of us with young families, our hopes are tempered by a haunting reality: the future we once dreamed of has shifted beyond reach. What remains is an obligation to understand the forces shaping this collapse, accept the inevitability of hardship, and try to adapt as the familiar falls away.
_______________________________________

The essay includes sections on climate change, biodiversity loss, economic and social erosion, and finally, "living through the polycrisis." I hope you'll find it helpful.

"As Earth’s temperature rises, agricultural practices will need to adapt. Droughts will likely become more frequent, and some land may no longer be arable."

"On top of that is the challenge of feeding an ever-growing population without expanding the production of fertilizer and other agrochemicals, which have a large carbon footprint that is contributing to the overall warming of the planet.

"Researchers across MIT are taking on these agricultural challenges from a variety of angles."

Addressing climate change is too expensive, they said. “Spain’s apocalyptic floods show two undeniable truths: the climate crisis is getting worse and Big Oil is killing us”

Agreed. What shall we do stop this happening?

We need our leaders to take concrete action to tackle the climate emergency, which includes halting new fossil fuel development and implementing a rapid, just and equitable phase-out of existing fossil fuels.
