Amazon deforestation and Brazilian President Bolsonaro’s attack on science

Amazon deforestation and Brazilian President Bolsonaro’s attack on science

Comments 0 Comment

Doug Boucher writes: Science is always a potential threat to authoritarian rulers, because it uncovers truths that contradict their lies. Recently we’ve seen a dramatic example of this conflict in Brazil, where the director of the National Institute for Space Research (INPE) has been fired by the country’s new President, Jair Bolsonaro, for releasing data showing a substantial increase in Amazon deforestation. INPE has been providing the world with measurements of deforestation, based on detailed analysis of satellite photos, for…

Smoke from wildfires in Siberia drifts east toward Canada and the U.S. on July 30, 2019. NASA By Nancy Fresco, University of Alaska Fairbanks The planet’s far North is burning. This summer, over 600 wildfires have consumed more than 2.4 million acres of forest across Alaska. Fires are also raging in northern Canada. In Siberia, choking smoke from 13 million acres – an area nearly the size of West Virginia – is blanketing towns and cities. Fires in these places…

The Guardian reports: From giraffes to sharks, the world’s endangered species could gain better protection at an international wildlife conference. The triennial summit of Convention on International Trade in Endangered Species (Cites), that began on Saturday, will tackle disputes over the conservation of great beasts such as elephants and rhinos, as well as cracking down on the exploitation of unheralded but vital species such as sea cucumbers, which clean ocean floors. Extraordinary creatures being driven to extinction by the exotic…

The latest threat to endangered species: The Trump administration

The latest threat to endangered species: The Trump administration

Comments 0 Comment

Carl Safina writes: Endangered species come on lists. But lists obscure relationships. What can it mean that a few mussels, some snails we’ve never heard of, obscure crayfish in marginal headwaters and some island-confined songbirds are vanishing? Some 1,650 species of animals and plants in the United States are listed under federal law as endangered or threatened. But when they are reduced to a line item on a list, their multimillion-year existences and roles in the complex living communities that…

No-till farming conserves soil by greatly reducing erosion. USDA NRCS South Dakota/Eric Barsness, CC BY-SA By David R. Montgomery, University of Washington It’s time to take soil seriously. As the Intergovernmental Panel on Climate Change states with very high confidence in its latest report, land degradation represents “one of the biggest and most urgent challenges” that humanity faces. The report assesses potential impacts of climate change on food production and concludes that rising atmospheric carbon dioxide levels will reduce crop…

It’s raining plastic: Microscopic fibers fall from the sky in the Rocky Mountains

It’s raining plastic: Microscopic fibers fall from the sky in the Rocky Mountains

Comments 0 Comment

The Guardian reports: Plastic was the furthest thing from Gregory Wetherbee’s mind when he began analyzing rainwater samples collected from the Rocky Mountains. “I guess I expected to see mostly soil and mineral particles,” said the US Geological Survey researcher. Instead, he found multicolored microscopic plastic fibers. The discovery, published in a recent study (pdf) titled “It is raining plastic”, raises new questions about the amount of plastic waste permeating the air, water, and soil virtually everywhere on Earth. “I…

Trump administration significantly weakens Endangered Species Act

Trump administration significantly weakens Endangered Species Act

Comments 0 Comment

The New York Times reports: The Trump administration on Monday announced that it would change the way the Endangered Species Act is applied, significantly weakening the nation’s bedrock conservation law and making it harder to protect wildlife from the multiple threats posed by climate change. The new rules would make it easier to remove a species from the endangered list and weaken protections for threatened species, the classification one step below endangered. And, for the first time, regulators would be…

E&E News reports: What’s good for the planet’s climate is also good for its food systems. Halting global warming and feeding the world’s rapidly growing population both require major overhauls to the way that humans manage the land they live on, according to a much-anticipated report from the Intergovernmental Panel on Climate Change. The report, released this morning, tackles the broad connections between climate change and land. With contributions from more than 100 scientists who reviewed thousands of research papers,…

The New York Times reports: Countries that are home to one-fourth of Earth’s population face an increasingly urgent risk: The prospect of running out of water. From India to Iran to Botswana, 17 countries around the world are currently under extremely high water stress, meaning they are using almost all the water they have, according to new World Resources Institute data published Tuesday. Many are arid countries to begin with; some are squandering what water they have. Several are relying…

The Guardian reports: Attempts to solve the climate crisis by cutting carbon emissions from only cars, factories and power plants are doomed to failure, scientists will warn this week. A leaked draft of a report on climate change and land use, which is now being debated in Geneva by the Intergovernmental Panel on Climate Change (IPCC), states that it will be impossible to keep global temperatures at safe levels unless there is also a transformation in the way the world…

Ethiopia plants 350 million trees in a day to help tackle climate crisis

Comments 0 Comment

The Guardian reports: About 350m trees have been planted in a single day in Ethiopia, according to a government minister. The planting is part of a national “green legacy” initiative to grow 4bn trees in the country this summer by encouraging every citizen to plant at least 40 seedlings. Public offices have reportedly been shut down in order for civil servants to take part. The project aims to tackle the effects of deforestation and climate change in the drought-prone country….

Some men avoid ‘green’ behavior because they don’t want to be perceived as gay

Comments 0 Comment

Tom Jacobs writes: There are many reasons people fail to act in environmentally friendly ways. Inertia, for some. Fatalism, for others. Then there’s the difficulty of fully grasping the long-term consequences of our actions. New research points to another, more surprising disincentive for going green: the fear that others might question our sexual orientation. As a 2016 study confirmed, environmentalism is widely perceived as feminine behavior. Even today, caring and nurturing behavior is associated with women—and that includes taking steps…

Protections slashed and forests fall in the Amazon under Brazil’s far right leader

Protections slashed and forests fall in the Amazon under Brazil’s far right leader

Comments 0 Comment

The New York Times reports: The destruction of the Amazon rain forest in Brazil has increased rapidly since the nation’s new far-right president took over and his government scaled back efforts to fight illegal logging, ranching and mining. Protecting the Amazon was at the heart of Brazil’s environmental policy for much of the past two decades. At one point, Brazil’s success in slowing the deforestation rate made it an international example of conservation and the effort to fight climate change….

Adam Federman reports: Every year, hundreds of petroleum industry executives gather in Anchorage for the annual conference of the Alaska Oil and Gas Association, where they discuss policy and celebrate their achievements with the state’s political establishment. In May 2018, they again filed into the Dena’ina Civic and Convention Center, but they had a new reason to celebrate. Under the Trump administration, oil and gas development was poised to dramatically expand into a remote corner of Alaska where it had…

Lori Garver, former deputy NASA administrator, writes: In a July Pew Research Center study, 63 percent of respondents said monitoring key parts of Earth’s climate system should be the highest priority for the United States’ space agency — sending astronauts to the moon was their lowest priority, at 13 percent ; 18 percent favor Mars. The public is right about this. Climate change — not Russia, much less China — is today’s existential threat. Data from NASA satellites show that future generations here…
