Previous health impact assessments of temperature-related mortality in Europe indicated that the mortality burden attributable to cold is much larger than for heat. Questions remain as to whether climate change can result in a net decrease in temperature-related mortality. In this study, we estimated how climate change could affect future heat-related and cold-related mortality in 854 European urban areas, under several climate, demographic and adaptation scenarios. We showed that, with no adaptation to heat, the increase in heat-related deaths consistently exceeds any decrease in cold-related deaths across all considered scenarios in Europe. Under the lowest mitigation and adaptation scenario (SSP3-7.0), we estimate a net death burden due to climate change increasing by 49.9% and cumulating 2,345,410 (95% confidence interval = 327,603 to 4,775,853) climate change-related deaths between 2015 and 2099. This net effect would remain positive even under high adaptation scenarios, whereby a risk attenuation of 50%

This special report on land comes at a time when the scientific evidence is unambiguous: the way we manage our land will directly determine the future of life on Earth. The planetary boundaries framework, highlighted in this report, is a critical scientific tool to understand the complex interdependencies between land, climate, biodiversity and water, among other Earth system components, offering policymakers a focused lens through which to view the potential risks and rewards of different land-use decisions.

China’s CO2 emissions fell by 3% in March 2024, ending a 14-month surge that began when the economy reopened after the nation’s “zero-Covid”

Oil in the North Sea is expected to be net-energy negative by 2031. This means that in 2031, it’ll cost more energy to extract the fossil fuels than we would gain by using them, rendering extraction unfeasibly expensive. Yet, rather than use our remaining years of access to these fuels to turbo-charge new energy infrastructure, fossil fuels are being extracted and burned for business as usual: quick cash. Around the world, the lights will go off in nations that don’t have back-up renewables. That’s most of them.

But the decline in oil, gas and coal will not be steep enough to limit global warming to 1.5C

Terrestrial ecosystems have taken up about 32% of the total anthropogenic CO2 emissions in the past six decades1. Large uncertainties in terrestrial carbon–climate feedbacks, however, make it difficult to predict how the land carbon sink will respond to future climate change2. Interannual variations in the atmospheric CO2 growth rate (CGR) are dominated by land–atmosphere carbon fluxes in the tropics, providing an opportunity to explore land carbon–climate interactions3–6. It is thought that variations in CGR are largely controlled by temperature7–10 but there is also evidence for a tight coupling between water availability and CGR11. Here, we use a record of global atmospheric CO2, terrestrial water storage and precipitation data to investigate changes in the interannual relationship between tropical land climate conditions and CGR under a changing climate. We find that the interannual relationship between tropical water availability and CGR became increasingly negative during 1989–2018 compared to 1960–1989

The EU have introduced a new regulation on the import of products linked to deforestation – but will this reduce deforestation globally?

La Niña is present.* Equatorial sea surface temperatures (SSTs) are below average across most of the Pacific Ocean. The tropical Pacific atmosphere is consistent with La Niña. La Niña is expected to continue into the winter, with equal chances of La Niña and ENSO-neutral during January-March 2023. In February-April 2023, there is a 71% chance of ENSO-neutral.*

For every three trees dying from drought in the Amazon rainforest, a fourth tree – even though not directly affected – will die, too. In simplified terms, that’s what researchers have now found using network analysis to understand the complex workings of one of Earth’s most valuable and biodiverse carbon sinks. The regions most at risk of turning into savannah are located on the forest’s Southern fringes, where continuous clearing for pasture or soy has already been weakening the forest’s resilience for years.

It’s hot and getting hotter. The first six months of the year are about 0.2°C cooler than the first six months of 2016 and 2020 (Fig. 1), but that’s only because the current La Nina continues to cool the tropics. Global temperature is rising despite the La Nina. Earth is out of energy balance (more solar energy absorbed than heat radiated to space) by an astounding amount – more than any time with reliable data – so, within a few years, we will be setting new global temperature records.

The Politics of the Anthropocene' is a sophisticated yet accessible treatment of how human institutions, practices, and principles need to be re-thought in response to the challenges of the Anthropocene, the emerging epoch of human-induced instability in the Earth system and its life-support capacities. The world remains stuck with practices and modes of thinking that were developed in the Holocene - the epoch of around 12,000 years of unusual stability in the Earth system, toward the end of which modern institutions such as states and capitalist markets arose....

At the global level, tropical areas are losing forests at a rate of 10 million hectares per year according to the FAO’s latest report on forest resources, and temperate areas, which are gaining forest area at a rate of 5 million hectares per year. Of the 10 million hectares of forest lost each year, just under two-thirds can be unambiguously attributed to agricultural expansion, with the remaining third being a combination of forest fires, logging and other factors.

A new report reveals that tropically forested countries are facing higher-than-ever rates of destruction, due to COVID-19.1 This has had – and will continue to have – a devastating impact on the environment, the global climate, and the many Indigenous peoples who rely on these ancient and biodiverse forests for their homes and sustenance, unless the governments of these countries are called to task and held accountable.

Freshwater is a fundamental resource in our world, even more than crude oil. Without freshwater, it would be impossible to maintain the current agricultural production that manages to feed nearly 8 billion human beings. Most of the world's agriculture, nowadays, is based on irrigation. It means that production depends on water that has been stored somewhere, naturally or artificially. And once you start depending on a limited stock of resources, you face a problem. Even renewable, if you exploit it faster than it renews itself, you will eventually run out of it. It is the phenomenon called "overexploitation"
