More than 11 thousand scientists from different areas published today (5) a alert in the journal BioScience which provides information on climate research over the last 40 years. Such a document states that the planet is in a state of climate emergency and proposes some actions to change this situation. 5m354a
In 1979, researchers from 50 countries met at the First World Climate Conference (First World Climate Conference) in Geneva, Switzerland, and agreed that action was needed to combat climate change. climate changes. This need was also the subject of later conferences and agreements, as in the Rio Conference in 1992 (Eco 92), in the Kyoto Protocol 1997 and more recently in the Paris Agreement, in 2015, in which several countries proposed to reduce the emission of greenhouse gases from 2020 onwards. The problem is that, even with so many warnings and agreements, greenhouse gas emissions continue in full swing, according to the warning made by scientists.
With a large number of bibliographic material in hand, the researchers made a summary in the form of graphics and information and stated that action is needed. According to them, efforts need to come from all countries, tly and also with individual actions. Furthermore, they suggest six critical steps that can be taken by society, governments and others to try to reduce climate change:
- Energy: it is necessary to rapidly implement energy efficiency practices that involve renewable energy sources and other cleaner sources. Fossil fuel subsidies must be eliminated and the richest nations must assist the less developed in the transition from these fossil fuels to less polluting sources;
- Short term pollutants: emissions of pollutants such as methane, soot, hydrofluorocarbons and more need to be reduced. This could help reduce the short-term warming trend by more than 50% over the next few decades;
- Take care of nature: we must protect and restore Earth's ecosystems. Phytoplankton, coral reefs, forests, swamps, mangroves and all other ecosystems contribute to the sequestration of atmospheric carbon. It is necessary to reduce the loss of habitat and biodiversity, protecting what is still left of our planet.
- Food: It is necessary to reduce the global consumption of products of animal origin, especially livestock. The production of this type of meat, for example, requires an absurd amount of water and occupies a very large cultivable area;
- Economy: overexploitation of ecosystems and over-extraction of materials must be reduced. Despite the economic growth they provide, it is necessary to adopt more sustainable practices;
- Population: it is necessary to stabilize the world population with policies that respect human rights and contribute to reducing the impact of population growth on greenhouse gas emissions and the loss of biodiversity. Such policies consider family planning services, promote gender equity, and include primary and secondary education for all.
Still, scientists say that these points are important, but that action should not be restricted to them and that much more can be done. In total, the alert was signed by 11.258 scientists from 153 different countries.
What is a climate emergency? 105z6g
In recent years, the term global warming started to be replaced by climate change ou climate crisis. Now, one of the most used is climate emergency. When a nation enacts a climate emergency, is like a call to warn about the need to act to reduce the effects of climate change. In May, the british parliament and Ireland declared a state of climate emergency. Following suit, the host city of the last climate agreement, Paris, made the same in July.
On the other hand, some countries seem to go in the opposite direction. Yesterday (the 4th), the Donald Trump, current president of the United States, have started the process to leave the Paris Agreement. The justification was that remaining in the agreement harms the country economically.
