Akatu comment: there is an interdependent relationship throughout history between human action and the impact on ecosystems and the climate behavior. It is not only the industrial pollution that generates this kind of climate change: deforestation, livestock large-scale use of means of transport powered by fossil fuels, and energy generated from polluting form also fall into this list. If consumers are part of the problem's origin, they are also part of their solution.
Through changes in their daily practices, consumers perceive themselves as citizens and empower, forcing companies to produce more cleanly. This new behavior and this new awareness are essential to reduce global warming and its bad consequences to the global climate. The year 2015 was turbulent for the environment by disaster tells how the dam in Mariana (MG), but also with hope, because the signing of the Paris Agreement, whose main objective is to get countries to strive to reduce emissions of greenhouse gases in the coming decades.
The manager of conservation strategies Boticário Group Foundation for Nature Protection, André Ferretti, has listed five demonstrations that climate change and its effects have arrived:
1. Increased temperature According to the UN, 2015 was the warmest year history, because of global warming, is already known, is influenced by man. In Brazil, the high temperatures were experienced throughout the year. The city of Rio de Janeiro recorded this year 43,2º C, with windchill of 47 C by the National Institute of Meteorology. The temperature is the highest since 1915, when he had the measurement beginning. Other cities also had record as Brasília (DF) which recorded the second highest temperature ever, with 35,1º, Manaus (AM), which reached 38,6º, highest record since 1925 and Belém (PA), which reached 38, remember heat since measurements began in 1897.
2. Lack of water The water crisis in South East is no longer new. Since 2014 the drop in rainfall is already a reality. However, the action of the man in the degradation of native vegetation surrounding rivers and reservoirs, and the lack of investment, has helped to enhance the water crisis. Similarly, the reduction of natural areas contributes to climate change as native vegetation play a fundamental role in regulating the microclimate, and when they are cleared, emit greenhouse gases. Despite the drop in interest this issue in the media, the levels in São Paulo reservoirs remain alarming. According to the water company of St. Paul (Sabesp), the Cantareira system, the most important of the state continues level of about 10%, i.e., still using the so called dead volume.
3. Floods If some states suffer from water scarcity, the south of the country was hit by devastating rains that caused flooding in the three states. In Rio Grande do Sul, the lake Guaíba, which cuts the state capital, has reached alarming numbers last year, reaching 2.80 meters, flooding many parts of the city. In Santa Catarina, the losses due to the floods exceeded R $ 500 million, according to Civil Defense. The Paraná registered a rarity in 2015: several tornadoes were seen in the city of Rondon in November, when the winds reached 115km / h. With great destruction, the city's mayor declared emergency. Extreme weather events are a direct consequence of climate change.
4. Desertification Lack of water causing so much trouble for people also has major consequences for nature. With climate change and the reduction in rainfall, Brazil expanded the areas hit by drought. In late October, satellite data from the US Agency Space (NASA) showed that the Southeast has lost 56 trillion liters of water, the worst drought in decades in the region. The Northeast also lost 49 trillion liters. The lack of water in the soil causes a process called desertification, in which the environment is modified to turn into a barren landscape or a proper desert.
5. Extinction of species With these changes in temperature and altered rainfall cycles, global and Brazilian biodiversity suffers increasingly. According to a study published in Science, one in six species could be extinct because of climate change, and the regions that are suffering most are South America, Australia and New Zealand. Here in Brazil, experts estimate that half of the species of Amazonian plants may disappear by 2050. According to them, this reduction in the number of trees emits greenhouse gases, which in turn feeds the climate change. It's a vicious cycle. - Play free content as long as the credits Akatu and site www.akatu.org.br be published. Learn more at www.akatu.org.br/DireitosAutorais
