Legionnaires' disease: How does the climate crisis and warming cities increase the risk of Legionella infections?

Heat waves, high humidity and increasing reliance on cooling towers and air conditioning create a breeding ground for Legionella bacteria, leading to recurrent outbreaks of Legionnaires' disease in New York, Ontario and other areas – a serious health threat
Droughts lead to severe water shortages, reduced food supplies and even severe restrictions on electricity consumption. Illustration: depositphotos.com

Without water, there is no future: UN report warns of an era of severe droughts and a global water crisis

A new UN report maps the world's drought hotspots – from Africa and the Panama Canal to the Mediterranean basin – and warns of growing damage to water supplies, food security and economic stability, which is also

When Wizz Air melted from the heat

Extreme heat waves force airlines to cancel flights, change schedules and face heavy costs. This was one of the reasons why Wizz Air stopped operating in Abu Dhabi. Will there be future

The heat is rising and the plate is emptying: The climate crisis is reducing agricultural areas worldwide and in the Middle East

New research suggests that the climate crisis threatens to shrink agricultural land around the world, especially in regions near the equator and in the Middle East. If we don't act, the ability to produce food will be severely affected.

The root of the problem: Trees in cities will save us from the heat

Population and energy consumption continue to rise, CO₂ concentrations remain in the atmosphere for decades, and extreme heat increases. Prof. Haim Kotiel calls for a shift in focus from emissions reduction alone to immediate adaptation: massive tree planting in cities

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.

If we don't change direction, these blackouts will only multiply

Opinion: The large power outage we experienced at the beginning of the month may be a preview of what is to come for the Israeli electricity sector with the increase in the frequency of heat waves due to the worsening of the climate crisis. The solutions are in our hands, now

Extreme climatic events are no longer rare. The result: a real threat to the animal world

Climate change and its devastating impact are well known. However, in the last two years we are increasingly witnessing the threatening consequences of extreme climatic events, as was the case last summer in England when a temperature of 40 degrees was measured for the first time.
