Amazon trees are found to be at risk

AP, By Seth Borenstein, November 22

Washington – A first-of-its-kind examination of the Amazon’s trees found that as many as half the species may be threatened with extinction or heading that way because of massive deforestation. Among the more than 5,000 tree species in deep trouble: the ones that produce Brazil nuts and mahogany.

An international team of 158 scientists found that depending on the degree to which deforestation comes under control in the next 35 years, between 36 and 57 percent of the 16,000 tree species in the tropical rainforest area would be considered threatened. The study is published in Friday’s edition of Science Advances.

The range rests on whether cutting down the region’s forest continues at the rate of the late 20th and early 21st centuries or slows to lesser levels proposed in 2006, study authors said. If deforestation continues at the same pace, nearly 8,700 tree types are in trouble, but the number of species at risk could be as low as 5,500 if nations are able to cut back as planned, said study coauthor Nigel Pitman, from the Field Museum in Chicago.

Paris attacks: State of emergency could restrict public demonstrations during Paris climate talks, By Peter Burton, November 17

What impact will the attacks have on the Paris Climate Change Conference scheduled to begin in 12 days?

While already complicated, the talks will now take place within a state of emergency that is threatening to limit public participation.

Events in Paris continue to unfold at a dizzying pace. But in the coming days we will learn a lot by paying attention to how parties use (and abuse) the language of freedom and liberty.

New NASA Data Shows Brazil’s Drought Deeper Than Thought

Reuters, October 30

Ottawa – New satellite data shows Brazil’s drought is worse than previously thought, with the southeast losing 56 trillion liters of water in each of the past three years – more than enough to fill Lake Tahoe, a NASA scientist said on Friday.

The country’s most severe drought in 35 years has also caused the Brazil’s larger and less-populated northeast to lose 49 trillion liters of water each year over three years compared with normal levels, said NASA hydrologist Augusto Getirana.

Brazilians are well aware of the drought due to water rationing, power blackouts and empty reservoirs in parts of the country but this is the first study to document exactly how much water has disappeared from aquifers and reservoirs, Getirana said.

“It is much larger than I imagined,” Getirana told the Thomson Reuters Foundation. “With climate change, this is going to happen more and more often.”

Worst Climate Threat You Never Heard of Is Stronger Than CO2

Bloomberg, By Alex Nussbaum, October 29

The biggest global warming battle you’ve never heard of kicks off in Dubai this weekend.

Climate negotiators from across the globe will gather in the Persian Gulf city to debate how to get rid of hydrofluorocarbons — a class of hundreds of artificial chemicals used in refrigerators, air-conditioners, fire suppressants and other widely used products. While less common than greenhouse gases like carbon dioxide or methane, HFCs can be thousands of times more potent, pound for pound, at heating up the planet.

They’re also gaining in popularity as demand for air conditioning, refrigeration and other services is expected to soar in developing countries in coming decades. The result: HFCs are now the world’s fastest growing greenhouse gases and projected to rise even more in the future.

A worldwide agreement coming out of the United Nations-run meeting in Dubai to quickly get rid of HFCs may keep the equivalent of 100 billion tons of CO2 out of the atmosphere by 2050 and avoid a half-degree Celsius of warming by century’s end, proponents say. That’s about a quarter of the 2-degrees Celsius (3.6-degree Fahrenheit) limit that scientists say is needed to avoid the worst effects of climate change.

Burning Hell Coming for Mideast Deserts

Discovery News, By Eric Niiler, October 26

If any place could be described as a living hell, it might be the desert regions of the Middle East. Hot, dry, dusty and arid, these harsh landscapes still manage to support cities populated by tens of millions of people who rely on air conditioning to survive.

Now scientists say that by the end of the century, the effects of climate change will push the region into a zone that surpasses the limits of human survival. They believe that most any outdoor activity will be hazardous.

“This is a significantly more severe type of heat wave than what people have experienced before,” said Elfatih Eltahir, professor of civil and environmental engineering at the Massachusetts Institute of Technology.

Exxon’s Own Research Confirmed Fossil Fuels’ Role in Global Warming Decades Ago

Top executives were warned of possible catastrophe from greenhouse effect, then led efforts to block solutions.

Inside Climate News, By Neela Banerjee, Lisa Song & David Hasemyer, September 16

At a meeting in Exxon Corporation’s headquarters, a senior company scientist named James F. Black addressed an audience of powerful oilmen. Speaking without a text as he flipped through detailed slides, Black delivered a sobering message: carbon dioxide from the world’s use of fossil fuels would warm the planet and could eventually endanger humanity.

“In the first place, there is general scientific agreement that the most likely manner in which mankind is influencing the global climate is through carbon dioxide release from the burning of fossil fuels,” Black told Exxon’s Management Committee, according to a written version he recorded later.

It was July 1977 when Exxon’s leaders received this blunt assessment, well before most of the world had heard of the looming climate crisis.

A year later, Black, a top technical expert in Exxon’s Research & Engineering division, took an updated version of his presentation to a broader audience. He warned Exxon scientists and managers that independent researchers estimated a doubling of the carbon dioxide (CO2) concentration in the atmosphere would increase average global temperatures by 2 to 3 degrees Celsius (4 to 5 degrees Fahrenheit), and as much as 10 degrees Celsius (18 degrees Fahrenheit) at the poles. Rainfall might get heavier in some regions, and other places might turn to desert.

Northern California Wildfires Prompt Emergency Declaration

New York Times, By Ashley Southall, September 13

Two wildfires in Northern California have devoured more than 100,000 acres of drought-parched land near Sacramento, injuring four firefighters and prompting Gov. Jerry Brown to declare a state of emergency on Sunday.

The California Department of Forestry and Fire Protection said the fires had forced thousands of residents to evacuate, and had damaged or destroyed homes, schools and highways.

A fast-moving fire that started on Saturday spread to 40,000 acres overnight and raged out of control on Sunday, prompting Mr. Brown to declare a state of emergency for Lake and Napa Counties.

More than 1,000 firefighters were dispatched to the blaze, called the Valley Fire, said Daniel Berlant, a spokesman for the state fire agency. Four were hospitalized on Saturday to be treated for second-degree burns.

In Radical Shift, GOP Leaders Actively Embrace Catastrophic Climate Change

Climate Progress, By Joe Romm, September 11

Over the past year, GOP leaders, driven by Senate majority leader Mitch McConnell (R-KY), have made a radical shift in the party’s public position on climate change. They are now actively seeking to destroy a global climate deal.

In any other universe this would be a major news story. But I guess the mainstream media has become so jaded to what the Koch brothers and Tea Party have done to the Republican party at a national level, that this radical shift seems just like another dog-bites-man-story, albeit one where the wound is fatal.

In fact, for most of the past quarter-century, most of the GOP leadership has at least given lip service to the idea that global warming is a global problem that needs a global solution. Not only have they abandoned that public position, but they now apparently believe the role of the “exceptional” and “indispensable” nation is to actively work to undermine the world’s best chance to save billions of people — including generations of Americans — from needless misery.

UN plan to save Earth is “fig leaf” for Big Business: insiders

Why the new Sustainable Development agenda is “fundamentally compromised” by corporate interests – UN records reveal that the intergovernmental body has already marginalised the very groups it claims to be rescuing from poverty, hunger and climate disaster.

Insurge Intelligence, By Nafeez Ahmed, September 4

At the end of this month, the UN will launch its new 2030 Sustainable Development agenda for “people, planet and prosperity” in New York, where it will be formally adopted by over 150 world leaders.

The culmination of years of consultations between governments, communities and businesses all over the world, there is no doubt that the agenda’s 17 Sustainable Development Goals (SDGs) offer an unprecedented vision of the interdependence of global social, economic and environmental issues.

But records from the SDG process reveal that insiders at the heart of the UN’s intergovernment engagement negotiations have criticised the international body for pandering to the interests of big business and ignoring recommendations from grassroots stakeholders representing the world’s poor.

Formal statements issued earlier this year as part of the UN’s Post-2015 Intergovernmental Negotiations on the SDGs, and published by the UN Sustainable Development Division, show that UN ‘Major Groups’ representing indigenous people, civil society, workers, young people and women remain deeply concerned by the general direction of the SDG process — whereas corporate interests from the rich, industrialised world have viewed the process favourably.

The Clean Power Plan Is Barely Better Than Kyoto; IPPC Says: We Must Remove CO2 From the Atmosphere

Truthout, By Bruce Melton, August 16

The EPA’s Clean Power Plan is 12 percent more stringent than the Kyoto Protocol, yet since 1978, the US has emitted as much carbon dioxide as we emitted in the previous 228 years. Globally, since 1984, our civilization has emitted as much carbon dioxide as in the previous 236 years.

The new EPA carbon regulations in the Clean Power Plan require about the same carbon dioxide emissions reductions as what was proposed at the Rio Earth Summit in 1992, when we as a global society first recognized that climate pollution was a problem. What resulted was the Kyoto Protocol, and its proposal to limit carbon dioxide emissions to 7 percent below 1990 levels in the US and similar levels in other developed countries.

The grand contradiction between the latest climate science and current climate policy is that since about the beginning of the Kyoto Era, we have emitted as much climate pollution as we emitted since mankind first began altering the carbon dioxide content of our atmosphere to a noticeable degree in the mid-1700s.


The myth comes from the ability of models to recreate abrupt changes. And the models truly are quite challenged when it comes to abrupt changes, or at least they were until last year. Researchers from the University of New South Wales and the University of Hawaii have successfully modeled abrupt changes over a portion of the past 100,000 years by simulating fresh water impulses from iceberg armadas in the North Atlantic. Not only do we know from physical evidence that these abrupt changes are real, but now we can model them.

We also have a great deal of physical evidence about what happened to our environment during natural climate changes of all kinds; impacts to forests, oceans, rainfall, etc. When we back the models up and run them with ancient climate conditions and ocean circulations, the models are accurate for the slow changes. As of last year, the models are even getting toward reliability for abrupt changes.

When everything is taken into consideration, the professional opinion of the IPCC as stated in its Summary for Policy Makers is that emissions reductions alone are nowhere near what are needed. Strong negative emissions are required. A large, continuous, net removal of carbon dioxide from our atmosphere is required.

The methods could be agricultural, reforestation and/or industrial and energy smokestack capture, but one thing is certain; all of these things combined will not create a large net removal of carbon dioxide from the atmosphere. Direct atmospheric removal of carbon dioxide is required.

This means that even progressive climate policy that is much more aggressive than the Clean Power Plan just adopted in Austin, Texas, that will strive to meet net-zero (or zero emissions of carbon dioxide) by 2030, are inadequate to say the least.

Final word: All is not lost. Treating climate pollution like the pollution it is can be done for similar costs to what we spend on advertising across the planet every year. The same voices that have so badly discombobulated the climate science discussion in the general population have also masked the true solutions to the treatment of climate pollution.
