The huge leaks of the potent greenhouse gas will doom climate targets, experts say, but stemming them would rapidly reduce global heating

The ice loss was hidden in places existing monitoring methods can’t reach, such as hard-to-map fjords. Machine learning helped scientist revise mass loss estimates and uncover patterns in glacial retreat.

EXPERT REACTION: UN report on migratory species shows shocking state of wildlife

		Nearly half (44%) of the world’s migratory species are showing population decline, according to the first-ever report on the State of the World’s Migratory Species by the Convention on the Conservati

The U.S government wants to crack down on the ballooning energy consumption of Bitcoin miners.

A network of climate science deniers has been accused of “hijacking” rural concerns over a new social media campaign “to save the farming industry”.  ‘No Farmers, No Food’ has gained over 50,000 followers on X in the fortnight since its launch, which was framed as a response to the widespread farmers’ protests sweeping across Europe.

Collapse in system of currents that helps regulate global climate would be at such speed that adaptation would be impossible

Prof Mark Howden, the director of the Australian National University Institute for Climate, Energy and Disaster Solutions, said the sector’s net zero target is “effectively not possible”.

“It’s pretty well embedded in the public consciousness that red meat is high profile in terms of greenhouse gas emissions per serve,” Howden said.

“I suspect the industry saw this as a fundamental threat to their future … A few years ago everybody was kind of jumping on the net zero bandwagon without actually thinking through what it actually meant,” he said.

The CSIRO found the industry would fall short of meeting its net zero target, and instead recommended the adoption of a “climate-neutral” target that would require a reduction of methane emissions rather their complete elimination.

As climate change redistributes terrestrial ecosystems across the globe, the world's natural capital is expected to decrease, causing a 9% loss of ecosystem services by 2100. That's according to a study of natural capital published in the journal Nature led by scientists at the University of California, Davis, and Scripps Institution of Oceanography at UC San Diego.

Due to clear-cutting, the area of undisturbed rainforests is decreasing. At the edges of deforested areas, temperatures rise, and there is more light. Trees are able to adapt to changes in their living conditions and environment, but how does environmental change affect the shape of trees in the tropical rainforest? To date there has been no overall understanding of this.

Associate Professor Eduardo Maeda from the University of Helsinki coordinated an international project investigating tree shapes on the edges of the tropical rainforest. Matheus Nunes, who previously worked at the University of Helsinki and is now active at the University of Maryland, headed a study where data were collected through terrestrial laser scanning to model Amazonian trees.

The findings were recently published in Nature Communications. The study clearly demonstrated that trees growing on forest edges are shaped differently from those growing deep in the forest.

“COP28 is now on the verge of complete failure,” former U.S. Vice President Al Gore said. But organizers of the summit in Dubai urged nations to be flexible and compromise.

Projected rate of warming has not improved in past two years, analysis shows

JT-60SA produces largest volume of plasma ever made by humans, paves way for ITER

The former U.S. vice president accused the United Arab Emirates of "abusing the public's trust" by naming the CEO of its national oil company as president of COP28.

A new study has found that chemical additives in everyday plastic might be stopping – or, at best, interrupting – the reproductive habits of a shrimp-like species that is key to the marine food chain. The findings provide a different perspective on the potential damage caused by specific pollutants.
