Queimadas são apenas a ponta do iceberg na devastação da Amazônia. Focos de calor destroem meios de sobrevivência de povos indígenas isolados, muitos dos quais ainda nem temos registros oficiais.
A situação brasileira atual é muito preocupante. As queimadas na Amazônia, estampadas na imprensa internacional, foram previstas com antecedência pelas ONGs, pelos órgãos de pesquisa e pela comunidade acadêmica. A reação do governo de Jair Bolsonaro (PSL) foi demitir cientista, a exemplo do Instituto Nacional de Pesquisas Espaciais (INPE), e insinuar que as ONGs estão por trás dos fatos. Essa situação revela algo maior que está acontecendo na América do Sul. Queimadas em larga proporção no Brasil, Bolívia, Paraguai e norte da Argentina apontam para políticas ambientais desastrosas. A reportagem é de Antenor Vaz, publicada por CartaCapital, 27-08-2019. O desmatamento, até o mês de julho deste ano, na Amazônia Brasileira foi de 278% maior do que o registrado no mesmo período do ano de 2018, conforme os dados do INPE. Leia mais. A atividade humana está secando o ar sobre a Amazônia. Um estudo recentemente apresentado por pesquisadores da NASA, na revista Scientific Reports of Nature, explica que, nos últimos 20 anos, a atmosfera sobre a Amazônia se tornou mais seca, aumentando a demanda por água e fazendo com que os ecossistemas da grande bacia tropical sejam mais vulneráveis a incêndios e secas.
A pesquisa também indica que essa secura do ar se deve principalmente às atividades humanas. A reportagem é de Pere Iñigo, publicada por El Ágora, 06-11-2019. A tradução é do Cepat. Cientistas do Jet Propulsion Laboratory (JPL) da NASA, em Pasadena, analisaram décadas de medições do terreno e da bacia do Amazonas para analisar duas questões relacionadas à umidade relativa do ar: qual é o grau de umidade do ar e quanto é necessário para manter as condições úmidas da floresta amazônica.

There’s another story to tell about climate change. And it starts with water. It’s easy for all concerned about air, water and nature to descend into despair as we watch brazen rollbacks of environmental legislation in the US.
Just last week, developments included an executive order to rewrite US carbon emissions rules, jeopardising the country’s ability to uphold its Paris climate talk commitment; the end of a moratorium on new coal leases; and the green-lighting of a pesticide claimed to cause harm to children. But as apathy is not an option, let’s try to think beyond the usual strategies. For one, we can recognise that the way we talk about our environmental challenges has interfered with our ability to truly grapple with them: that we limit ourselves by creating too simple a story. Diego Gazola - Você tem um minuto para olhar para o céu... Planting the Rain to Grow Abundance. O futuro da Amazônia - Piseagrama. Numa definição livre, a floresta tropical é um tapete multicolorido, estruturado e vivo, extremamente rico.
Uma colônia extravagante de organismos que saíram do oceano há 400 milhões de anos e vieram para a Terra. Entre as folhas, ainda existem condições semelhantes àquelas da primordial vida marinha. A floresta funciona como um mar suspenso – que contém uma miríade de células vivas – muito elaborado e adaptado. Evoluída nos últimos 50 milhões de anos, a Floresta Amazônica é o maior parque tecnológico que a Terra já conheceu, porque cada um de seus organismos, entre trilhões, é uma maravilha de miniaturização e automação.
Carbon dioxide must be removed from the atmosphere to avoid extreme climate change, say scientists. Humans must start removing carbon dioxide from the atmosphere as soon as possible to avoid saddling future generations with a choice between extreme climate change or spending hundreds of trillions of dollars to avoid it, according to new research.
An international team of researchers – led by Professor Jim Hansen, Nasa’s former climate science chief – said their conclusion that the world had already overshot targets to limit global warming to within acceptable levels was “sufficiently grim” to force them to urge “rapid emission reductions”. But they warned this would not be enough and efforts would need to be made to reduce the amount of carbon dioxide in the atmosphere by about 12.5 per cent. This, the scientists argued, could be mostly achieved by agricultural measures such as planting trees and improving soil fertility, a relatively low-cost way to remove carbon from the air. “These tasks are formidable and … they are not being pursued globally.” Reuse content.

Nova biografia resgata a visão revolucionária de Alexander von Humboldt - Página22. O naturalista, já no século XVIII, entendeu a natureza como uma força global, interligada e interdependente.
Mas suas lições parecem ter sido esquecidas Alexander von Humboldt nasceu na Prússia, atual Alemanha, em 1769. Foi verdadeiramente um naturalista, mas também um geógrafo e explorador que, aos 32 anos de idade, se aventurou numa fascinante viagem pela América Latina, explorando-a e descrevendo-a pela primeira vez sob um ponto de vista científico. Nesta viagem, Humboldt iniciou também uma viagem conceitual que lhe permitiu, pela primeira vez na História, desenvolver uma nova visão da natureza. Five Principles of Extraordinary Math Teaching. American retirement funds contribute to deforestation and climate change. Even as a new administration hostile to efforts to combat global warming is poised to take over the White House, climate activists in the U.S. are continuing to push for action in myriad and sometimes even unexpected ways.
For instance, you may not realize that saving for your golden years could have an impact on the global climate, but a movement is currently underway to make the retirement funds relied on by millions of Americans free of any connection to deforestation and associated carbon emissions due to investments in palm oil producers.
The Department of Justice Must Investigate ExxonMobil. You can join the call to action be signing our petition to the DOJ here.
Leaders of many of the country’s largest environmental groups, civil rights organizations, and indigenous peoples movements issued a joint letter today calling on the Department of Justice to investigate ExxonMobil, after revelations that the company knew about climate change as early as the 1970s, but chose to mislead the public about the crisis in order to maximize their profits from fossil fuels.
“Despite Exxon’s wealth and power, people were eager to sign on to this statement,” said Bill McKibben, co-founder of 350.org. “Anyone who’s lived through 25 years of phony climate debate, or who’s seen the toll climate change is already taking on the most vulnerable communities, has been seething at these revelations. Seething With Anger, Probe Demanded into Exxon's Unparalleled Climate Crime.
A broad coalition of community groups along with prominent leaders from the nation's top civil rights, environmental, and indigeneous people's movements on Friday sent a joint letter to the U.S.
Department of Justice demanding a federal investigation into allegations that oil giant ExxonMobil knew about the role fossil fuels played in driving climate change since the 1970s but concealed that information—and later sought to discredit those issuing warnings—in order to protect its own financial interests. "Anyone who’s lived through 25 years of phony climate debate, or who’s seen the toll climate change is already taking on the most vulnerable communities, has been seething at these revelations.
" "Given the damage that has already occurred from climate change—particularly in the poorest communities of our nation and our planet—and that will certainly occur going forward, these revelations should be viewed with the utmost apprehension," the letter states.

It's all too easy to distance and doubt ourselves away from climate facts. Particularly since they are sometimes presented in abstract, doom-laden, fear-mongering, guilt-inducing, and polarizing ways. Clima em transformação. O objetivo é conter o aumento da temperatura média do planeta a no máximo 2°C até 2100, em relação aos valores pré-Revolução Industrial. De 1850 para cá, o clima já aqueceu, em média, 0,85°C. Os tais 2°C são o aquecimento valor considerado seguro por cientistas para evitar as mudanças mais dramáticas do clima. Países desenvolvidos e em desenvolvimento apresentaram ao longo deste ano as chamadas INDCs, conjunto de compromissos que os países dizem ser capazes de adotar para colaborar com esse processo.

Global warming could be more devastating for the economy than we thought. Posted on 27 October 2015 by dana1981 A new study published in Nature by scientists at Stanford and UC Berkeley has made waves for its finding that thus far we have dramatically underestimated the damage human-caused climate change will do to the global economy.
By looking at data from 160 countries across the 50-year period from 1960 to 2010, the authors found that an average local temperature of 13°C (55°F) is economically optimal, particularly for agricultural productivity. That temperature roughly reflects the current climate in many wealthy countries like the USA, Japan, France, and China. If regional temperatures are cooler, then warming benefits the local economy, but past that peak temperature, warming reduces economic productivity.
Policy: Climate advisers must maintain integrity. Illustration by Phil Disley Disenchantment has set in well ahead of the 21st Conference of the Parties (COP21) to the United Nations Framework Convention on Climate Change (UNFCCC) in Paris in December. Scientists, policy-makers and the public already accept that progress will not be enough to keep global average temperature rise within the 2 °C limit set at the 2010 UN climate summit.
The negotiations' goal has become what is politically possible, not what is environmentally desirable. Gone is a focus on establishing a global, 'top down' target for stabilizing emissions or a carbon budget that is legally binding. A shift in climate.

Extreme heatwaves could push Gulf climate beyond human endurance, study shows. Plants Communicate Using An Internet of Fungi. Hidden beneath the surface and entangled in the roots of Earth’s astonishing and diverse plant life, there exists a biological superhighway linking together the members of the plant kingdom in what researchers call the “wood wide web”. This organic network operates much like our internet, allowing plants to communicate, bestow nutrition, or even harm one another. The network is comprised of thin threads of fungus known as mycelium that grow outwards underground up to a few meters from its partnering plant, meaning that all of the plant life within a region is likely tapped into the network and connected to one another. The partnership of the roots of plants and the fungi is known as mycorrhiza and is beneficial for both parties involved; plants provide carbohydrates to the fungi and in exchange, the fungi aids in gathering water and providing nutrients such as phosphorus and nitrogen to its partnering plant.
“Branching threads of fungus mycelium in organic soil” Stanford researchers' calculations reveal high global economic cost of climate change. A study co-authored by Stanford and UC Berkeley researchers indicates that the global economy will take a big hit from climate change, with rich countries affected as well as poor. (Michael Bischof) Stanford Report, October 21, 2015 Stanford-Cal collaboration finds that without climate change mitigation, even wealthy countries will see an economic downturn by 2100.
