To fully experience the astronomical phenomenon of a total eclipse, you need to prepare in advance. The main concern is eye safety, but there are other health risks that can easily be avoided. We explain the main personal precautions to bear in mind.

Rising sea levels have quadrupled the frequency of extreme events related to this phenomenon along coastlines since 1900. This is one of the conclusions of a study, which included Spanish participation, suggesting that climate change has already altered the risk of coastal flooding and highlighting the need to integrate these changes into adaptation and risk management strategies. More than 680 million people worldwide live in low-lying coastal regions, where small changes in sea level can significantly affect flood risk. The study is published in Nature Climate Change and aligns with another paper, published the same day in Science Advances, which states that since the 1970s, the number of days on which sea levels have exceeded annual averages has tripled.

An analysis by World Weather Attribution shows that players and fans face a much higher risk of extreme heat and humidity at the 2026 FIFA World Cup—to be held from June 11 to July 19 in North America—compared to the 1994 tournament held on the same continent. The report analyzes the likelihood that each of the 104 matches to be played in Canada, the United States, and Mexico will meet the safety guidelines set by the FIFPRO players’ union. Nearly a quarter of the matches will be played when conditions exceed a wet-bulb temperature of 26°C—an index that measures the body’s ability to cool itself—which requires cooling breaks. In addition, five matches will exceed the 28°C threshold for this indicator—equivalent to 38°C in dry heat—a limit set by FIFPRO for postponing matches.

The latest forecasts from the European Centre for Medium-Range Weather Forecasts (ECMWF) suggest that there is a likelihood that the phenomenon known as El Niño will return this year and that it will do so with greater intensity. In Europe, for June through August, the forecast indicates a slight tendency toward below-average precipitation in the northeast of the continent. As for the Iberian Peninsula, temperatures are expected to exceed the top quintile of the seasonal average. Although it is not yet certain that this will occur, forecasts for the coming months will either confirm or rule it out.

According to the Ministry for Ecological Transition and Demographic Challenge, masses of African air with varying concentrations of surface dust are expected to reach the Canary Islands and the Iberian Peninsula on Wednesday. Health authorities in different provinces have recommended avoiding outdoor physical exercise or activities that require effort, especially for vulnerable groups such as children, pregnant women, the elderly and the sick.

In 2025, climate change drove extreme weather events around the world, disproportionately affecting vulnerable and marginalised communities. In addition, global temperatures were exceptionally high, heatwaves were significantly more intense than 10 years ago, and millions of people were pushed to the limits of their ability to adapt. These are the main conclusions of the 2025 report published by the World Weather Attribution initiative, whose experts believe that ‘drastically reducing fossil fuel emissions remains the key policy for avoiding the worst impacts of climate change’.

Using data from the 180 companies with the highest carbon emissions—fossil fuel and cement producers—research has calculated that these companies contributed 50% to the increase in heatwave intensity since 1850-1900. The authors estimate that the individual emissions of each large polluting company may have contributed to the occurrence of between 16 and 53 heatwaves. The study, published in Nature, also shows that a quarter of the heatwaves recorded between 2000 and 2023 would have been virtually impossible without anthropogenic climate change.

Climate change has made the hot, dry and windy weather conditions that spread fires across the Iberian Peninsula 40 times more frequent and 30% more intense than in the pre-industrial climate, according to a rapid study by World Weather Attribution. The ten-day heatwave was also 200 times more likely and 3°C hotter due to climate change. The study, which analysed weather observations rather than climate models, warns that fires in Europe are overwhelming firefighting resources and highlights the importance of controlling vegetation in affected areas.

The State Meteorological Agency (AEMET) has reported that a warm weather will bring temperatures 6 to 7 ºC higher than normal for this time of year throughout Spain. According to AEMET, 29 May to 1 June could be the warmest days for this time of year since at least 1950.
