Research published in Science assesses for the first time quantitatively the climate projections made by scientists at oil company Exxon and ExxonMobil Corp between 1977 and 2003. According to the study, most of their projections accurately predicted warming consistent with subsequent observations. However, the authors point out that the company's public statements contradicted its own scientific data.
New estimates published in Science claim that under the most optimistic scenarios, glaciers will globally lose much more mass and contribute more to sea level rise than current estimates, including those published in the latest IPCC report.
Since records have been kept, the year we are about to end has been the warmest in Spain. Added to this is a severe meteorological drought and the numerous and powerful wildfires that we record in summer. Adapting our society to these extreme events as a consequence of climate change should be a top priority.
Governments meeting at the COP15 UN Biodiversity Conference in Montreal (Canada) have reached an agreement after two weeks of negotiations. The "Kunming-Montreal Global Biodiversity Framework" aims to protect one third of land and oceans by 2030.
Although in 2020 the covid-19 pandemic caused confinement and economic paralysis in many countries, the rate of methane growth in the atmosphere peaked, reaching the highest level since 1984. Research published in Nature claims that the main source would be the warmer, wetter wetlands of the northern hemisphere.
Based on the Decalogue of recommendations for climate change communication signed in 2018 by more than 80 media outlets, environmental communication professionals from all over Spain, together with the scientific team of the Climate Change Communication Observatory, have drawn up the new Decalogue 2022, a guide for the social communication of the climate crisis. A summarised version is reproduced below.
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.
