2024 was the warmest year on record. Global temperatures exceeded 1.5°C above pre-industrial levels for the first time, the critical threshold set by the Paris Agreement. This change brought with it not only new temperature records, but also a number of extreme weather events with devastating consequences.

Extreme heat on every continent

The heatwave of 2024 hit every continent, with records breaking from Europe to Asia:

– Europe experienced its hottest summer on record. Italy, Spain and Greece battled temperatures exceeding 45°C, leading to massive fires and property losses.

– Asia faced temperatures of up to 50°C in India and Pakistan, causing power outages and increased deaths from heatstroke.

– North America experienced widespread drought, with temperatures in California and Texas reaching record highs of 54°C, severely affecting water supplies.

July 2024 recorded the hottest day on record. More than 5 billion people were exposed to extreme temperatures that day, with climate change likely playing a significant role.

Health, economic and environmental impacts

The extreme heat of 2024 had wide-ranging consequences for health, the economy, and the environment.

– Health risks: Extreme heat led to a significant increase in deaths from heatstroke and exacerbations of chronic diseases. The elderly, children and those without access to air conditioning were the most vulnerable. The World Health Organization estimates that more than 100,000 people will die from extreme heat in 2024.

– Economic losses: Agriculture was among the hardest hit sectors. Drying soils and heat stress on plants caused a decline in yields of staple crops such as wheat, corn and rice. This decline triggered a sharp increase in food prices on global markets.

– Energy sector faced serious challenges. Increased demand for air conditioning led to overloading of electrical networks and power outages.

– Natural disasters: Extreme heat and drought have resulted in massive wildfires that have caused enormous damage to property and ecosystems. For example, in Canada, more than 5 million hectares of forest burned during the summer of 2024, the largest area recorded in modern history.

Climate mechanisms behind extremes

Scientists point to rising concentrations of greenhouse gases in the atmosphere as a major factor in these extreme events. Natural climate cycles such as El Niño have amplified the effects of global warming. With higher temperatures, the atmosphere can hold more moisture, leading not only to heat waves but also to more intense storms and floods.

Necessary measures

Experts point out that 2024 is clear evidence that the climate crisis is already happening. Without urgent action to reduce greenhouse gas emissions, extreme weather will become increasingly frequent and destructive.

– Mitigation measures:

– Faster transition to renewable energy sources.

– Improving energy efficiency and reducing dependence on fossil fuels.

– Strengthening international cooperation to protect forests and oceans, which absorb carbon.

– Adaptation steps:

– Building more resilient infrastructure that can handle extreme temperatures and floods.

– Increasing funding for health systems to cope with climate threats.

– Investments in water management projects to secure water resources during droughts.

The year 2024 reminded us that the climate crisis is no longer a threat of the future, but an integral part of our present. If humanity does not step up its efforts to protect our planet, extreme events like those of 2024 will only be a harbinger of the future. It is time to act – for the future of our planet and the generations that will come after us. Spring
