Large Dams Fail on Climate Change and Indigenous Rights

Brazil has flooded large swaths of the Amazon for hydro dams, despite opposition from Indigenous Peoples, environmentalists and others. The country gets 70 percent of its electricity from hydropower. Brazil's government had plans to expand development, opening half the Amazon basin to hydro. But a surprising announcement could halt that.


In an interview with O Globo, Mines and Energy Executive Secretary Paulo Pedrosa said the government is reconsidering hydro construction in the face of societal pressure, environmental damage and increasingly competitive renewable energy options.

We can see parallels in Canada, where large hydro projects have been pushed through despite similar opposition and concerns.

With an October election in Brazil, things could change, but we hope whatever government holds power will recognize there are better options than large-scale hydro. We also hope the BC government will reconsider its decision to proceed with Site C.

Hydropower isn't as "green" as many people once thought, and climate change creates new challenges. Decades of research show greenhouse gas emissions from large hydroelectric projects can be substantial, especially if carbon dioxide emitted during steel and concrete manufacturing and construction activities is accounted for.

Decomposing materials in reservoirs emit methane, a far more potent greenhouse gas than CO2 over the short term. A 2016 study confirmed findings of studies from Canada and elsewhere going back decades that methane emissions from hydro dams are far greater than previously estimated. Minimum emissions are similar to those from generating electricity using natural gas. And receding glaciers and changes in precipitation patterns from global warming put hydro dams at risk because of lower water levels.

Large-scale hydro also causes enormous environmental and social damage, including farmland and habitat destruction, changes to waterways and water tables, and displacement of Indigenous Peoples. Where large areas of land are flooded, mercury in fish increases several-fold, making this traditional source of protein risky to eat.

In Canada, large-scale projects such as Site C in BC and Muskrat Falls in Labrador run counter to our commitments to combat climate change and respect Indigenous Peoples' rights. Both projects are over budget and years behind schedule.

Canada's auditor general recently found the current mid-century climate strategy won't meet our international commitment to reduce greenhouse gas emissions by 80 percent between 2005 and 2050.

These facts and rapid improvements in electricity generation suggest Canada should rethink its climate strategy. Renewable energy options can generate needed electricity for lower cost and in a timelier manner, as a recent Site C analysis shows. Conservation measures can reduce energy needs.

Solar and wind power have increased in efficiency and decreased in cost at several times the rates estimated a decade ago. The lowest electricity cost in Canada is from an Alberta wind farm, which will supply 600 MW of electricity at an average cost of 3.7 cents per kWh, at least three times lower than Site C power.

Fears that solar and wind are unpredictable have been nullified by recent developments in mega-storage batteries. In November, Tesla installed a 100-MW battery in Australia's outback to handle power outages and daily demand fluctuations. In contrast to recent hydroelectric projects, it was delivered ahead of schedule and on budget.

Despite Natural Resources Canada's identification of enormous geothermal resources in Canada, this power source has scarcely been considered, except for shallow heat pumps for individual dwellings and buildings. Many oil and gas wells in Western Canada reach hot water, which might be used either directly or to map underground isotherms that allow efficient drilling for geothermal power. Expertise for drilling geothermal wells already exists in the oilpatch, facilitating the transfer of jobs from old fossil fuel technology to less carbon-intensive industries.

Provincial and federal government ministers have touted continued development of oilsands, LNG-fired electricity and pipelines as interim activities needed to make the transition to a low-carbon economy. As the auditor-general's report demonstrates, these activities will prevent Canada from fulfilling its international obligations to reduce emissions. We have neither need nor time for transitional industries.

Brazil's announcement sets an example. Canada must also meet its commitments to reduce greenhouse gases and improve relations with Indigenous Peoples. To do so requires avoiding the massive hydro development that Canada's mid-century climate plan would require and instead rapidly transition to modern energy sources.

Heavy Rain Could Trigger Mudslides in Fire-Weary California

Northern California, which is already reeling from the deadliest and most destructive wildfire in state history, is now bracing for heavy rainfall this week.

The forecasted rain could bring much-needed relief for the firefighters battling the Camp Fire in Butte County. However, it could also bring new hazards due to possible ash, mud and debris flows triggered by the rain.

What Should We Know About Wildfires in California

By Rolf Skar

The Camp Fire raging in Northern California is now the most devastating and deadly fire in the state's recorded history. Simultaneously, deadly and destructive fires are burning in Southern California, as the Woolsey and Hill fires have engulfed iconic areas of Malibu and West Hills. With dozens dead, hundreds missing and thousands of structures destroyed, our hearts go out to those impacted across the region.

Cristina Stinson never had an allergic reaction to ragweed until after she started working with it. "I think the repeated exposure to the pollen is what did it," she said. It also didn't help that her community is chock-full of it. "There is plenty of ragweed in my neighborhood," she said. "In fact, it grows right outside my door."

Zinke Blames ‘Radical Environmentalists’ for Historic California Wildfire

In an interview with Breitbart News on Sunday, Secretary of the Interior Ryan Zinke blamed "radical environmentalists" for the wildfires that have devastated California in recent weeks, The Huffington Post reported.

"I will lay this on the foot of those environmental radicals that have prevented us from managing the forests for years. And you know what? This is on them," he said in the interview.

You can listen to the whole thing here:

The remarks come as California has suffered the deadliest blaze in the state's history. The death toll from the Camp Fire, which destroyed the town of Paradise in Northern California, has now risen to 79. Around 1,000 people are still listed as missing, and the fire is now 70 percent contained, according to an Associated Press report Monday.

California Governor Jerry Brown blamed climate change in a statement made last weekend.

"Managing all the forests everywhere we can does not stop climate change, and those who deny that definitely are contributing to the tragedies that we are witnessing and will continue to witness," Brown said.

Regardless, Zinke has remained consistent in pointing the finger at forest management. His current criticisms echo his remarks following other fires this August, in which he said the increasingly frequent and violent blazes were the result of inadequate forest management, and not climate change. He continued in that vein during Sunday's interview:

"In many cases, it's these radical environmentalists who want nature to take its course. We have dead and dying timber. We can manage it using best science, best practices. But to let this devastation go on year after year after year is unacceptable, it's not going to happen. The president is absolutely engaged."

President Donald Trump has indeed vehemently blamed forest mismanagement ever since the recent batch of fires broke out, even threatening at one point to withhold federal funding if the forests weren't managed properly. During a visit to California Saturday to survey damage, Trump brought up forest management again, suggesting that the problem in California was that the forests were not raked enough.

"You look at other countries where they do it differently, and it's a whole different story," he said, as CNN reported. "I was with the president of Finland, and he said: 'We have a much different [sic] ..., we're a forest nation.' And they spent a lot of time on raking and cleaning and doing things, and they don't have any problem," he added.

Finnish President Sauli Niinistö, however, told a Finnish newspaper he did not recall suggesting raking to Trump.

"I mentioned [to] him that Finland is a land covered by forests and we also have a good monitoring system and network," he said.

Finnish people have taken to Twitter to poke fun at the U.S. President's statement using the hashtag "Raking America Great Again."

Despite Trump and Zinke's criticisms, the fact remains that the federal government controls almost 60 percent of the forests in California while the state controls only three percent. Paradise was surrounded by federal, not state, forests. Further, the fires in Southern California spread in suburban and urban areas, The Huffington Post reported.

Some think the emphasis put by Zinke and Trump on forest management is not about preventing fires at all but rather an attempt to justify opening more public forests to private logging interests.
