The World Meteorological Organization (WMO) has raised alarms over the potential development of a strong El Niño event in the tropical Pacific Ocean between May and July, with some models suggesting it could intensify into a “super” El Niño. Such ocean warming phenomena have historically contributed to surges in global temperatures and heightened the frequency of extreme weather events. Scientists emphasize that in an era of rising global temperatures, El Niño episodes may exacerbate heat levels, threaten agricultural yields, strain water resources, and disrupt ecosystems worldwide.

Meanwhile, seismic activity has been reported in multiple regions. The Greek island of Crete experienced a sequence of tremors over several days, though no damage or injuries were reported. Additional earth movements were felt in areas including south-central Russia, Japan’s Hokkaido Island, Costa Rica, the mid-Mississippi Valley in the United States, and Southern California’s interior.

A significant marine ecological shift was documented along Panama’s Pacific coast, where a crucial ocean process known as seasonal upwelling abruptly failed in 2025. This phenomenon, essential for bringing cold, nutrient-rich waters to the surface, supports the foundation of local marine ecosystems. The disruption, attributed to weakened northerly trade winds, led to reduced nutrient availability, warmer coastal waters, and threatened fisheries and coral reefs. Though upwelling has resumed this year, its irregular pattern has raised concerns over its future stability amid changing climate conditions.

In Colombia, over 50 nations convened in Santa Marta for the first global conference exclusively dedicated to phasing out fossil fuels. The gathering aimed to advance climate action beyond the framework of the annual United Nations climate summit (COP), where consensus requirements and opposition from major oil- and gas-producing countries have often stalled progress. This coalition of countries seeks more decisive measures to address fossil fuel dependence and accelerate the transition to cleaner energy sources.

The Mediterranean region is facing ecological challenges from invasive fish species. Researchers have identified at least 151 non-native fish inhabiting freshwater and coastal ecosystems, with 106 species now established and reproducing in the wild. Countries such as Italy, Spain, and France exhibit the highest concentrations, largely due to trade, aquaculture, and recreational fishing activities. The introduction of these species can be traced back to the opening of the Suez Canal in 1869, with climate change further facilitating their spread.

Global food security is increasingly under threat from the rising frequency and severity of extreme heat events. A joint report from the Food and Agriculture Organization and the WMO highlights that more than one billion people could face risks to their livelihoods and health due to heat-driven damage to crops, livestock, fisheries, and forests worldwide.

Advancements in climate science continue as researchers at the Scripps Institution of Oceanography develop a new artificial intelligence method called GOFLOW. This technique analyzes ocean surface temperature data from satellites to map subtle, fast-moving ocean currents with unprecedented precision. The improved understanding of these currents promises to enhance climate models, weather forecasting, and knowledge of marine ecosystems.
