The planet's capacity to store carbon emissions in geological formations is 1,460 gigatons, according to a study published in the journal Nature. This ceiling is likely to be reached by 2200 under current global warming mitigation scenarios, so, according to the authors, countries should reconsider the role of carbon storage in their plans to reduce emissions.
So-called ‘supercell thunderstorms’ — incredibly intense phenomena that bring hurricane-force winds, hail, torrential rain and often tornadoes — will become more frequent in Europe as the Earth continues to warm. This is the conclusion of a study published in Science Advances, which indicates that the increase could reach 11% in a scenario where temperatures rise by 3°C.
The frequency and intensity of extreme heat events have increased in recent years, heightening the risks for those who work outdoors and indoors. Health risks include heatstroke, dehydration, kidney dysfunction and neurological disorders. These are some of the conclusions of a joint report by the World Health Organisation (WHO) and the World Meteorological Organisation (WMO), which estimates that worker productivity falls by between 2% and 3% for every degree above 20°C. The document proposes measures for governments, businesses and health authorities to mitigate the risks of extreme heat for these people.
Space-based solar power could provide electricity to support Europe's net-zero emissions target if its cost of supply is reduced sufficiently. This is one of the conclusions of an article published in the journal Joule, by the Cell Press group. Space solar panels would allow continuous capture of solar energy, rather than only when light reaches Earth, reducing the need for wind and solar energy on Earth by 80% in Europe. The researchers estimate that by 2050, space-based solar power could reduce the costs of the European electricity system, although this depends on the development of two NASA space-based solar power designs they have used for their research: the Innovative Heliostat Swarm and the Mature Planar Array.
Four people have died in the fires that began last weekend on the Iberian Peninsula and have spread to different areas of Galicia, Castile and León, Andalusia, Castile-La Mancha, Extremadura and Madrid. The heatwave that continues to grip the country, strong gusts of wind and their changing direction, and the thermal drought are hampering firefighting efforts. The government declared on Tuesday a pre-emergency phase and thousands of people have had to be evacuated.
Extreme wildfires are becoming more frequent and causing greater environmental and social impact. Current policies that prioritise fire suppression have not only failed to prevent this situation from arising, but actually made it worse. The report Changing Wildfires - Policy Options for a Fire-literate and Fire-adapted Europe, released by the European Academies' Science Advisory Council (EASAC), addresses this issue by outlining eight policy options. The report's key recommendations focus on putting landscape management first —by regulating biomass structure and land use — and empowering local communities.
The concrete used by the Roman Empire was used to build aqueducts, bridges and buildings that have lasted for over two thousand years. A study analyses whether returning to this ancient material would help to decarbonise modern cement. According to the authors, reproducing the recipe would require a similar amount of energy and water, with similar CO2 emissions; however, its durability could make it a more sustainable option. It is published in the Cell Press journal iScience.
Forests cover approximately 40% of Europe's land area. Between 1990 and 2022, they absorbed around 10% of the continent's emissions from human activity, but this process is slowing down. An international team, including CREAF and CSIC, analyzes this decline and its causes in an article and proposes possible solutions. The work is published in the journal Nature.
Today at 3:00 PM CEST, the International Court of Justice in The Hague, the principal judicial body of the United Nations, will issue its advisory opinion on the obligations of states in relation to climate change and the legal consequences of those obligations. The case stems from a Pacific youth initiative, taken up by the small island nation of Vanuatu, which led a coalition of 132 countries to request an opinion. It is expected to determine whether large, polluting countries should be held accountable for damages caused to small island nations.
The last few weeks have been marked by devastating fires in Spain and other European countries. In Catalonia, just days after a fire killed two people and burned 5,500 hectares in the province of Lleida, another fire broke out in the province of Tarragona, affecting more than 3,200 hectares and now stabilised, which resulted in another person's death. What are the characteristics of these large fires? How can we prevent them? The Science Media Centre Spain organised an informative meeting with two experts to answer these questions and clarify key concepts.
