Global Warming

New data indicates the current El Niño is the strongest ever measured, marking a major shift in global weather patterns. The warming of the Pacific is expected to bring droughts, floods and temperature extremes across many regions, and scientists are watching closely for impacts on agriculture, water supplies and extreme weather in the months ahead.

Attention is on a developing El Niño that commentators describe as unlike any previously recorded. The claim, made in a widely shared science explainer, suggests the current event is stronger or behaving differently than past El Niños, raising questions about extreme weather, hotter global temperatures and disrupted rainfall patterns in the months ahead.

A new report says global temperatures have reached record highs as the El Niño climate pattern strengthens in the Pacific. El Niño, which warms ocean surface waters and alters weather worldwide, is adding to the underlying warming trend driven by greenhouse gas emissions. Scientists warn the combination could push average temperatures to new extremes in the coming months, with implications for heatwaves, droughts and storms across many regions.

The 2023-24 El Niño is described as record-shattering, with analysis of its wide-ranging effects on global temperatures, weather patterns and ecosystems. The event has driven exceptional ocean warming in the tropical Pacific, contributing to record global heat, shifts in rainfall, droughts and flooding in various regions, and stress on fisheries and agriculture. Commentators are weighing how much of the recent temperature surge should be attributed to El Niño versus longer-term climate change.

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.

A New York Times opinion piece warns that the current strong El Niño, a warming of the tropical Pacific that shifts global weather patterns, is set to drive severe conditions including heatwaves, droughts, floods and storms across many regions. The author urges governments and the public to prepare now for the disruption, arguing that early planning could limit the damage as the phenomenon reaches full strength in the coming months.

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 US National Environmental Satellite, Data, and Information Service is highlighting the outlook for a very strong El Nino in 2026-2027. The agency says an unusually warm tropical Pacific Ocean could reshape weather patterns worldwide, with potential effects on rainfall, droughts, storms and temperatures across multiple continents in the coming years.

New analysis indicates the global heatwave season has expanded by roughly 39 days, with extreme heat now arriving earlier in the year and lasting longer than before. Researchers attribute the lengthening season to warming temperatures, warning that prolonged exposure raises health risks and strains infrastructure. Coverage highlights how gradual change can go unnoticed even as extreme heat events become more frequent and severe.

New reporting highlights that emissions already released by the world's biggest polluters will continue driving global warming for decades, even if new pollution stops. The findings underline the long-lasting effect of carbon dioxide in the atmosphere and the lag between emissions cuts and temperature stabilization. Commenters are stressing the urgency of holding major emitters accountable and the limits of near-term climate action.

A UK climate minister has warned that the global food system is vulnerable to El Niño, the periodic warming of Pacific Ocean waters that disrupts weather patterns and can hit crop harvests. The warning highlights concerns that extreme weather linked to El Niño could drive up food prices and threaten supply security at a time of already strained agricultural conditions.

The Atlantic has yet to produce a hurricane this season, and climate outlet Grist attributes the calm to El Niño. The phenomenon, which is driving record ocean temperatures worldwide, creates wind shear over the Atlantic that suppresses tropical storm development. The piece notes the irony that the same pattern raising global temperatures is also canceling Atlantic tropical activity, at least for now.

The Guardian has published an explainer on El Niño, the periodic warming of sea surface temperatures in the tropical Pacific that can drive droughts, floods and heatwaves across the globe. The piece outlines what causes the phenomenon, how it disrupts weather patterns, and what steps communities and governments can take to reduce the risks it poses.

Climate rallies are being planned across France following a summer of record-breaking temperatures. Le Monde reports that demonstrations are being organised nationwide as campaigners seek to push the government for stronger climate action. The mobilisation follows months of extreme heat, with organisers and participants calling attention to the country's vulnerability to global warming.

A commentary argues that human rights and climate change can no longer be treated as separate issues, framing rising temperatures, displacement and resource shortages as direct threats to basic rights such as housing, food and safety. The piece calls for rights-based approaches in climate policy, a debate gaining traction among advocates and policymakers as climate impacts intensify worldwide.

Debate is focusing on who bears responsibility for keeping global warming within the 1.5-degree Celsius limit set by international climate goals. The question touches on the division of duties between wealthy historical emitters and developing nations, as well as the roles of governments, corporations and individuals. Observers say blame and burden-sharing remain among the most contested issues in climate negotiations.

PBS NewsHour reports on scientists developing new ways to control mosquito populations as rising global temperatures expand the habitats where the insects and the diseases they carry can spread. The segment examines research approaches to targeting mosquitoes as warming climate conditions push the public health threat into previously unaffected regions.

Warmer global temperatures are altering the timing of seasonal events, with spring arriving earlier in many regions and traditional calendar expectations no longer matching what people observe. Commentators note that earlier blooms, shifting migration patterns and milder winters are disrupting agriculture, gardening and cultural traditions tied to the seasons, prompting debate over whether the old sense of when spring begins still means anything.

A new examination asks whether animal and plant species can adapt quickly enough to keep pace with rapid global warming. The core question is whether evolutionary change can match the speed of rising temperatures and shifting habitats, or whether species unable to adapt in time will face decline or extinction as climate change accelerates.

Colorado has endured record-smashing heat this year, and the question being raised is whether such extreme temperatures will become the state's new normal as the climate changes. The discussion reflects growing concern that this summer's unprecedented heat may be less an anomaly than a preview of future conditions for the region under continued global warming.

Deutsche Welle examines how rivers are being transformed by global warming, exploring what hotter temperatures mean for water levels, flow patterns and the ecosystems and communities that depend on them. The report looks at how climate change is reshaping river systems worldwide as heat records continue to mount.

A new study questions the widely held idea that climate change is driving a boom in global squid populations. Researchers challenge assumptions that warming oceans have benefited squid, suggesting earlier conclusions may need revision. The findings matter for fisheries and marine ecosystems, where squid play a key role and where management decisions have partly relied on expectations of continued growth.

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.

Commentators are arguing that the growing public backlash against data centers, driven by concerns over energy use, water consumption and local impacts, has so far failed to become a broader reckoning about the climate cost of digital infrastructure. Writers on climate-focused online communities say the debate should connect data center expansion to emissions and grid strain, but that discussion remains largely framed around local nuisance rather than global warming.

New research suggests that major climate shifts triggered rare, rapid bursts of evolution in bird species, driving the diversity seen today. According to the findings, periods of environmental change pushed birds into adaptive surges rather than gradual transformation. The study is drawing attention as an example of how climate change can reshape life on Earth over deep time.

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.

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.
