The year 2021 is a La Niña year, and La Niña events typically lead to droughts in southeastern Brazil where São Paulo, the world’s fourth largest city, is located. La…

Record floods are battering the western and central Amazon, inundating Manaus and other communities and wrecking crops. To prevent future extreme weather events, deforestation and carbon emissions must be controlled.

The Brazilian president is making big promises to reduce Amazon deforestation, even as he moves to legalize large scale land theft with potentially catastrophic results for Earth’s climate and the Amazon.

Even in this era of “alternative facts,” the letter to the New York Times from Norte Energy (the company responsible for Brazil’s Belo Monte Dam) will surely be remembered as…

The planned 650 MW dam on the Rio Branco in Brazil’s Roraima state is scheduled to become operational in 2028; it could do extraordinary socio-environmental harm.

The reconstruction of the BR-319 highway — a north-south cut through what remains of Brazil’s Amazon forest — is being fast tracked by Pres. Bolsonaro, but the project risks huge socio-environmental impacts.

Brazil’s current 10-year Energy Expansion Plan calls for three more large dams in Amazonia by 2029, and the country’s 2050 National Energy Plan lists many more — putting the environment at risk.

A bill in Congress on the verge of passage this week would allow land grabbers to self-declare their ownership of government land, ultimately converting vast stretches of Amazon rainforest to cattle ranches.

The biodiverse rainforest of the Amazon’s Purus and Madeira river basins is at risk; new roads could be built to eventually serve extensive oil and gas wells.

Bolsonaro has backed off from Paris withdrawal “for now,” but his actions imply emissions exceeding Brazil’s carbon cut pledge.

The imminent election this month of far right Jair Bolsonaro as Brazil’s new president poses threats to the environment, indigenous people, and the global climate.

In January 2018, two officials announced an end to plans for Brazilian mega-dams; both have since been replaced, and to date, no planned dams have been cancelled.

To avoid impeachment on corruption charges, Brazil’s president has bought Congress and wealthy elite ruralists with a wave of decrees that will destroy the Amazon.

The term “controversial” is inadequate to describe the São Manoel Dam. It is located only 700 m from the Kayabí Indigenous Land and has already provoked a series of confrontations…

On August 23, 2017, Brazil’s president Michel Temer issued a decree revoking the RENCA (National Reserve of Copper and Associated Minerals), an area the size of Switzerland on the northern…
