While fires have always been here, the climate crisis appears to be exacerbating both their frequency and intensity. The giant fire in the Jerusalem hills on Independence Day. Photo: Yair Barkan

How do we prevent the next fire?

Huge fires are spreading in Israel and around the world with increasing frequency. Experts point to the climate crisis and the urgent need for forest management, budgets and awareness to prevent future disasters.

The CO2-Driven Climatic Roller Coaster: A 485-Million-Year Journey

A new study published in the journal Science detailed the fluctuations in the Earth's temperature over the past 485 million years, and highlighted the significant relationship between the Earth's temperature and the levels of carbon dioxide in the atmosphere

Getting even hotter and no one cares about third world residents

The climate crisis is already here. For the residents of the poor countries considered the "Third World", there is no doubt the culprits: the rich Western countries. Not only do they avoid actions to prevent warming, they also continue to develop sources of pollution

Rain at the time

Recent research has shown that in the future there will be fewer rainy days in our region due to the climate crisis, but there will be more strong rain events. How can this be explained using simple scientific principles?

This is a wake-up call: global warming and deforestation pose a real danger to animals

New study: The combination of global warming and deforestation may lead to the mass extinction of animal species

Research: The climate crisis may reduce life expectancy by half a year

A one degree Celsius increase in global average temperature due to the man-made climate crisis could shorten life expectancy by about 5 months, with women and residents of developing countries disproportionately affected

Corals from the Red Sea have invaded Israel's Mediterranean coast

Until now, the low temperatures of the Mediterranean water in winter have been a barrier to the arrival of tropical corals. The establishment of the Dendronaphtia we found indicates that at least last winter, the waters of the Mediterranean Sea were warmer than before

Etrog in danger: will it be impossible to grow etrog in Israel in the future?

The etrog is currently at risk due to the rise in global temperatures as part of the climate crisis, and it is possible that the day will come when we will no longer be able to grow etrogs in Israel - for the first time in 2,500 years
This map depicts the global temperature anomalies for the meteorological summer in 2023 (June, July and August). It shows how much warmer or cooler different regions of the Earth were compared to the baseline average from 1951 to 1980: NASA Earth Observatory/Lauren Dauphin

The climate crisis delivered a strong blow: the summer of 2023 was the hottest ever

This raw data is analyzed using methods that take into account the variable distance between temperature stations around the world and the effects of urban heat islands that may distort the calculations.
