global climate

UN News examines how the recent global energy crisis has accelerated the shift toward renewable energy, arguing that solar, wind and other clean sources are redefining what energy security means for countries worldwide. The piece frames the transition away from fossil fuels as both a climate necessity and a strategic move to reduce dependence on volatile fuel supplies.

Discussion is turning to what it means for global warming to exceed the Paris Agreement's 1.5°C threshold. Commentators are explaining that breaching the limit does not mean climate action is pointless, but signals that average temperatures have risen beyond the target, with worsening heatwaves, sea-level rise and ecosystem stress. The debate centres on how overshoot could be temporary and whether warming can be brought back down.

The Guardian examines a common corporate argument that individual companies' fossil fuel emissions are too small to matter, a 'drop in the ocean' compared to global totals. The piece asks what the picture would look like if the full real-world costs of those emissions were properly counted, challenging firms to account for their cumulative contribution to climate damage rather than deflecting responsibility.

Scientists report that as the Pacific Ocean warms, its water-age structure is behaving counterintuitively: young water at the surface appears to be aging, while older deep water is getting younger, a reversal of established circulation patterns. The finding suggests climate change may be disrupting the ocean's overturning circulation, with potential consequences for heat and carbon storage. Researchers say the shift warrants closer monitoring of how the Pacific redistributes heat as global temperatures rise.

World leaders gathered at the United Nations General Assembly told one another that humanity is 'in this together', a message of shared responsibility on global challenges. The line has been picked up widely across US and international outlets, but commentary is focusing on the practical question: how that solidarity would actually operate in practice on issues like conflict, climate and cooperation.

World leaders, citing climate change as an existential threat, are demanding that the United Nations function effectively on the issue. The call reflects frustration among governments over stalled international climate action and the UN's struggles to deliver coordinated global responses to warming, extreme weather and rising sea levels affecting member states.

The International Union for Conservation of Nature used the UN General Assembly and New York Climate Week to advance its agenda on nature protection, ocean conservation and climate action. The organisation says the gatherings offered a key moment to push for stronger commitments linking biodiversity and climate policy ahead of upcoming global negotiations.

A new analysis argues that diversifying staple crops to include millets would strengthen food security, improve nutrition and support sustainability across the Global South. The piece frames millets as climate-resilient, nutrient-rich grains that could reduce dependence on a narrow set of cereals, and calls on developing countries to promote their cultivation and consumption as part of broader agricultural and food policy strategies.

Palau's President is speaking out about his country's mission to combat climate change. As leader of a small Pacific island nation highly vulnerable to rising seas, he has made climate action a central cause, pressing for stronger international commitments to cut emissions and protect low-lying island states facing existential threats.

A scientific colloquium has been published examining the legacy of Syukuro Manabe, the climate physicist whose pioneering computer models laid the foundation for simulating and understanding global warming. Manabe's work, recognised with the 2021 Nobel Prize in Physics, is credited with first showing how rising carbon dioxide levels drive changes in the Earth's climate.

The Permanent Representative of Antigua and Barbuda delivered an address as part of the general debate of the 81st session of the United Nations General Assembly in New York. Small island states traditionally use this podium to press priorities such as climate change, debt relief and maritime rights, but no details of the speech were given in the available coverage.

Climate researchers are explaining how a Kelvin Wave affects ocean waters. A Kelvin Wave is a large-scale movement of warm water along the equatorial Pacific that can raise sea surface temperatures and influence weather patterns, including developments tied to El Nino. Scientists say understanding these waves helps forecast shifts in ocean conditions and global climate impacts in the months ahead.

A widely shared statistic states that the Earth's climate system is accumulating heat at a rate equivalent to the energy released by four Hiroshima atomic bombs every second. The figure illustrates the scale of excess energy trapped by greenhouse gases, most of which is absorbed by the oceans. It has become a common way for scientists and communicators to make global warming's pace tangible to the public.

The European Union is taking part in the FAO's Committee on Forestry and the 10th World Forest Week, meetings held at the UN food and agriculture agency in Rome. The EU delegation is presenting its positions on global forest protection, sustainable forest management and forest-related climate policy. The gathering brings together governments and experts to coordinate international action on forests.

Canada and the European Union are discussing a partnership framed as an 'Alliance for the Future', combining economic and ecological cooperation. Coverage in IPS Journal examines what such an alliance could mean for trade, climate policy and their broader relationship at a time when both sides are seeking reliable partners amid shifting global alliances.

3 E Network Technology Group has launched a global request for proposals to supply high-density AI infrastructure for its data center in Mikkeli, Finland. Vendors worldwide are invited to bid on the project, which signals the company's push into AI computing capacity in Northern Europe, a region drawing interest for data centers thanks to cool climate and renewable energy.

The 81st session of the United Nations General Assembly is under way at UN headquarters in New York City, bringing together delegations from member states for the annual high-level debate. The gathering typically features speeches by heads of state and government, alongside diplomatic meetings on conflicts, climate and global development. The assembly comes at a moment of heightened international tension, drawing attention to what world leaders prioritize on the UN's main stage.

New reporting suggests climate change may substantially shift where one of the world's vital crops can be grown, potentially redrawing the agricultural map as temperatures and rainfall patterns change. Details of which crop and which regions are affected remain limited in the available coverage, but the story is circulating widely across news outlets.

A widely viewed online video is promoting the idea that 'blue smoke' could be the solution to global warming, drawing more than 127,000 likes. The claim comes from a channel known for sceptical takes on science and technology, and is drawing attention and debate among viewers about its scientific merits.
