The Pacific Islander Students Who Made the Climate Crisis a Global Legal Issue

An initiative that began in 2019 among 27 law students in Vanuatu led to a historic opinion from the International Court of Justice. Now the Pacific island nations are trying to turn the ruling into a roadmap at the UN: Less

Cruise ships as a hotspot for outbreaks: What does the Hanta incident on the MV Hondius teach us?

The deaths of three passengers and the cluster of Hantavirus cases on the MV Hondius expedition ship illustrate anew why cruise ships are a particularly vulnerable environment for the spread of disease: crowding, shared spaces, water and air systems, and an elderly population

Artificial night light disrupts the immune system of wild rodents

A study from Tel Aviv University found that artificial lighting at night, even at the intensity of street lighting, disrupts the activity patterns of the immune system in wild rodents and may increase the risk of mortality.

Why is climate policy stalling despite broad public support?

An article in The Conversation argues that the gap between public support for reducing emissions and the continued use of fossil fuels stems from power structures, inequality, and perceptions that limit the sense of what is possible.

Light pollution disrupts crickets' circadian rhythms and threatens their reproduction

Further research on crickets reveals that light pollution throws them out of sync, impairs their reproductive ability, and threatens their continued existence.

Climate crisis also threatens democracy: Elections in more than 50 countries have been disrupted by natural disasters

A report by International IDEA found that at least 94 elections and referendums were disrupted between 2006 and 2025 due to floods, fires, heat waves and storms.

For the first time: Artificial intelligence maps ocean currents from high-resolution satellite images

The GOFLOW system, developed under the leadership of Tel Aviv University, allows for the identification of subtle flow movements in the ocean and may improve models of the climate crisis, storms, and heat and gas exchange between the sea and the atmosphere.

Europe in 2025: Heat waves from the Mediterranean to the Arctic Circle, peak fires and retreat of snow and glaciers

The ECMWF and WMO European Climate Status Report found that 95% of Europe experienced above-average heat, 70% of rivers flowed below average, and more than 10,000 square kilometers burned.

Report: Earth is out of balance, and heat trapped in the climate system has peaked

For the first time, the World Meteorological Organization has added the “Earth’s Energy Imbalance” index to its annual climate report — an index that illustrates how quickly the climate system is gaining heat.

Paul Ehrlich, author of “The Population Bomb,” dies at 93

The Stanford University biologist and environmentalist was one of the most influential and controversial voices in environmental science: a leading scientist in the field of ecology, who warned about population pressure on natural systems many years before the climate crisis became a reality.

Global study: Extreme heat is already limiting the ability to live, work, and move safely

A global analysis of temperature and humidity from 1950 to 2024 shows that the number of hours during which heat and humidity limit safe daily activity has increased sharply, especially for those aged 65 and over and in hot, vulnerable areas.

US withdrawal creates vacuum in global climate leadership

The EPA's reversal of the risk finding marks a sharp turn in American climate policy, but even though China is a leader in the production of green technologies, it is still unclear whether anyone is willing to fill the political vacuum that Washington is leaving.

Tropical rainforest birds are disappearing even in undisturbed forests – researchers fear a new “silent spring”

Long-term monitoring data in Brazil, Panama and Ecuador indicate a sharp decline in birds, especially insectivorous species, and it is possible that the climate crisis and the decline in insect numbers are destabilizing tropical forest ecosystems.

New study: Global warming has been accelerating since 2015

Analysis of five global datasets shows that the rate of warming in the past decade is almost double that measured between 1970 and 2015

Endless plastic: Are we polluting the planet forever?

A study from Norway warns that marine plastic waste is releasing long-lasting chemicals and heavy metals into freshwater bodies, while cleanup efforts are failing to keep up with the rate of pollution buildup.
Climatic tipping points are critical thresholds in Earth's systems – such as the oceans, ice sheets and forests – where warming can push the climate to a new state. Once the threshold is crossed, the changes are difficult to reverse and can set off a chain reaction that affects ecosystems, extreme weather events and the global climate. Credit: ESA

Accelerated warming could lock Earth into a greenhouse orbit, warn One Earth researchers

Analysis of 16 “tipping points” suggests that the accumulation of feedbacks – from forests to glaciers and oceans – could accelerate warming even if emissions fall in the future, creating a “desert” of climate stability

Extreme heat doesn't affect everyone the same—and it could deepen inequality in cities

Exposure to extreme heat is associated with real health risks — heat stroke, worsening of cardiovascular disease, and harm to at-risk populations such as the elderly, children, and outdoor workers.

Israeli study: Seasonal streams release microplastics into the Mediterranean Sea in “release” waves after rains

An Israeli study has revealed that seasonal streams are dumping large amounts of microplastics into the Mediterranean Sea. In the summer, the plastic particles accumulate, and during the rains, they are released in a large wave into the sea.
