The Great Migration of Small Birds: Who Will Be More Threatening – the Climate Crisis or Humans?

Small migratory birds, weighing no more than a few grams, travel thousands of kilometers each year between their nesting sites in Europe and their breeding grounds in Africa. Dr. Yoav Perlman of the Israel Ornithology Center warns that food shortages, hunting

Pathogens, storms and extreme temperatures: the causes of mass sea urchin deaths

A pair of studies from Tel Aviv University map 110 mass mortality events of sea urchins since 1888 and show that pathogens are the main cause, while also presenting a "corona swab" method for non-invasive genetic sampling under the skin.

Israelis downplay the severity of the climate crisis – at the bottom of the international ranking

A survey in 25 countries found that only 42% of Israelis see the climate crisis as a serious threat – the lowest rate in the sample; terrorism (89%) and infectious diseases (55%) are higher in the order of priority. In Turkey, this increased to 70% compared to 47%

Not just beautiful: the atolls—the reef engineers that produce sand and save coral

Parrotfish are herbivores that grind down algae and stone, contribute up to ~70% of the sand on tropical beaches, maintain reefs—and also exhibit unique behaviors such as a mucous “sleeping bag” and early storm prediction.

"The climate crisis threatens the Sea of Galilee" – coastal areas are being exposed, water quality is being damaged, and fish stocks are dwindling

A new comprehensive study by Prof. Avital Gazit and Dr. Tamar Zehari of Tel Aviv University reveals how long-term climate change is causing the sea level to recede in the Sea of Galilee, the growth of new vegetation, and damage to the ecosystem.

How to cool down a hot city: New guide helps authorities fight urban heat

In an era of record-breaking temperatures and scorching neighborhoods, cities must prepare for next summer – now. A new professional document provides local authorities with practical tools to cool the street, the neighborhood, and the entire city.

New study refutes the theory that human evolution in Africa was caused by climatic drying

Brown University researchers have discovered that North Africa remained relatively wet even during a period of global climate change – a finding that challenges the link between drying and the paving of humanity.

New study reveals mysterious jet-like winds accelerating Doomsday glacier melt

By focusing on the low-level jets over the Amundsen Sea region, the team was able to uncover important clues that explain how the Thwaites and Pine Island glaciers are losing ice at an increasing rate – a process that contributes

The glaciers are lost. Prepare for massive sea level rise

Even a temporary increase of 3 degrees Celsius will cause massive and irreversible glacier loss – up to 16% more than in a situation where the 1.5 degrees Celsius limit is not exceeded – which will affect sea levels.
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.

NASA: Climate crisis doubles the extremes of forest fires worldwide

Satellites detect dramatic increases in the frequency, intensity and extent of extreme fires due to global warming. There are plenty of reasons for fires. Human error would be more forgivable if it weren't for warming

Globalization allows for the rapid movement of goods, allowing rich countries to preserve their nature but at the cost of harming the nature of poor countries.
