After two long weeks of negotiations and outside the official deadline, COP27 has reached an agreement to create a loss and damage fund to help the most vulnerable countries face the impacts of the climate crisis. However, other issues such as greater ambition in mitigation strategies to avoid exceeding 1.5ºC of warming and less dependence on fossil fuels have not achieved the commitment of all parties.
At current CO2 emission levels, there is a 50 % chance of exceeding 1.5°C warming in nine years. This is one of the conclusions of the Global Carbon Budget 2022 report presented by its coordinator, researcher Pep Canadell, at a briefing organised by SMC Spain.
The Global Carbon Project (GCP) today releases its Global Carbon Budget 2022 report. The main conclusion is that there is no sign of a decrease in global CO2 emissions and, at current levels, there is a 50 % chance of exceeding 1.5°C warming in nine years. The results will be published in the journal Earth System Science Data.
In the midst of an energy, economic and geopolitical crisis, and still in a pandemic, the Climate Summit in Egypt (COP27) will kick off on 6 November with the challenge of bringing the climate fight to the forefront. We explain the main stumbling blocks, the unfinished business from the previous summit and the goals it has set itself.
A study published in Science Advances estimates that economic losses due to heatwaves caused by climate change between 1992 and 2013 exceeded $5 trillion. Moreover, lower-income countries were more affected than richer regions.
An international study published in the journal PNAS has associated deforestation and climate change with different species of monkeys and lemurs that usually live in trees spending more time on the ground. This implies that they would be exposed to a greater number of hazards. The research has taken place in 47 species in different parts of the Americas and Madagascar.
Red kites (Milvus milvus) born during a period of drought are disadvantaged throughout their lives, according to a study of a population of red kites in the Doñana National Park. The research is published in Nature Communications.
A study published in Science analyses the potential climate benefits of afforestation - both planting trees to create new forests and reforesting old ones - of the world's drylands. The authors show that the cooling effect of afforestation of this vast area would only amount to a decrease of about 1 % of projected greenhouse gas emissions in the business-as-usual and medium-emissions climate scenarios.
The Plenary of the Senate has approved this afternoon the Proposition of Law for the recognition of legal personality to the Mar Menor lagoon and its basin. The law, which was approved in Congress last July, comes from a Popular Legislative Initiative signed by more than 600,000 people.
International research on more than 3,000 tree and shrub species in 164 cities -including Barcelona, Valencia and Santa Cruz de Tenerife- reveals that up to two-thirds of urban tree species may already be experiencing climatic conditions that exceed their potential climate tolerance. The study is published in Nature Climate Change.
