Climate crisis becomes a culture war: How populism is hindering the fight

Climate crisis becomes a culture war: How populism is hindering the fight

As the evidence for warming becomes more tangible, climate denial is not disappearing but changing form: Instead of simply challenging the science, populist leaders are portraying climate policy as a conspiracy by experts and elites against “the citizens.”

President Herzog: Climate must be above all controversy

At the 54th Annual Science and Environment Conference in Jerusalem, the President of the State called for regional cooperation in the areas of climate, energy and food security. The Mayor of Jerusalem presented the alternative to the White Ridge Plan, and during the conference, awards were presented

In the Knesset, they mixed real climate engineering with the "spraying" conspiracy

Climate engineering by reflecting some of the sun's radiation is a real, dangerous, and controversial field of research that justifies regulation and transparency. However, in the Knesset debate, the scientific issue was mixed with conspiratorial claims about existing "sprays" in the sky.

Lament for Humanity: Nature is not a consumer product

After decades in reserves, deserts and savannas, Dr. Assaf Rosenthal summarizes his environmental credo: Nature is not a tourist product or an unlimited reservoir of resources, but the living system on which it relies.

The June 2026 heat wave in Europe: Same air pattern, much warmer world

Europe didn't get a new climate overnight, but its starting point changed quickly. The same atmospheric pattern that brought heat in the past is now producing much higher temperatures, as the continent has already warmed by about 2.5 degrees Celsius.

Climate models reproduce heat waves in the Middle East – but miss the path to them

The heat wave in Israel may actually have started with atmospheric changes occurring thousands of kilometers away. A new study has found that models are successfully reproducing the heat wave – but not always the warning signs that preceded it.

Super El Niño: Earth is gaining heat at a record rate, the energy balance has doubled in recent decades

An international scientific update states that the Earth's energy imbalance is at its peak. Most of the heat is absorbed by the oceans, but the consequences are felt in heat waves, rising sea levels and changes in precipitation.
Cows graze in a green meadow, against the backdrop of research on targeted grazing cessation for soil restoration and carbon sequestration.

Targeted cessation of grazing could sequester huge amounts of carbon in the soil

New research suggests accurately mapping pasture areas where stopping cattle grazing would allow vegetation and soil to be restored, sequester large amounts of carbon dioxide, and reduce the damage to meat and milk production.

UN report: Artificial intelligence consumes not only electricity, but also water, land and metals

A new report from the United Nations University warns that the growth of AI is creating a vast environmental footprint: data centers, cooling, power generation, mineral mining, e-waste, and inequality between countries that deploy the technology and those that do not.

El Niño approaches for a warmer world: Scientists warn of heat waves, fires and severe flooding

The development of El Niño in the Pacific Ocean is expected to increase extreme events in the coming months. But researchers emphasize that the climate crisis is the main factor that is intensifying the danger to health, forests, and ecosystems.

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.

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.

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.

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.

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.

Researchers have detected and measured a pollution plume following the breakup of a Falcon 9 rocket stage in the upper atmosphere (approximately 80–110 km) after an uncontrolled reentry in February 2025—and warn that commercial space activity is expanding faster than oversight
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.
