Why renewables can’t save the planet | Michael Shellenberger | TEDxDanubia

Environmentalists have long promoted renewable energy sources like solar panels and wind farms to save the climate. But what about when those technologies destroy the environment? In this provocative talk, Time Magazine “Hero of the Environment” and energy expert, Michael Shellenberger explains why solar and wind farms require so much land for mining and energy production, and an alternative path to saving both the climate and the natural environment. Michael Shellenberger is a Time Magazine Hero of the Environment and President of Environmental Progress, a research and policy organization. A lifelong environmentalist, Michael changed his mind about nuclear energy and has helped save enough nuclear reactors to prevent an increase in carbon emissions equivalent to adding more than 10 million cars to the road. He lives in Berkeley, California.

Personally, I think the way to go is with cleaner natural gas plants, along with some renewables where they make sense and conservation efforts -- and realize that most of climate targets are jokes -- and that we are all going to have to suffer from whatever climate instability is out there. Nuclear is a dying technology, not only is it dangerous, expensive, and silly compared to just burning the fossil fuels directly. But he does make a good point about renewables and the problems they can pose.

CO2 levels are at an all-time high — again – The Verge

CO2 levels are at an all-time high — again – The Verge

Planet-heating carbon dioxide in the atmosphere averaged 419 parts per million this May, according to the National Oceanic and Atmospheric Administration (NOAA). That pileup of CO2 is comparable to where it was a little over 4 million years ago, when the average global temperature was about 7 degrees Fahrenheit hotter and sea levels were a whopping 78 feet higher than they are today.

Without much more drastic action, scientists warn, CO2 levels will keep trending upward — which also brings the world closer to more inhospitable temperatures and coastal flooding

As the climate change debate has advanced, the arguments surrounding it have become more subtle. Outright denial of the climate problem is rare – so rhetoric has shifted to delaying urgent action. In this review of a paper by Steinberger, Lamb et al, I run down the new “discourses of climate delay”

I am a strong believer in a very high carbon tax and repealing most taxes on income and investing

Very high energy prices would make America a much more efficient country, by raising prices on all materials. The low cost of materials and energy is the greatest crisis facing America and our world today. If everything was a lot more expensive, people would buy a lot less stuff and would find ways to repair existing products. It would be so good for American communities.

Greenhouse gases are shrinking the stratosphere

Greenhouse gases are shrinking the stratosphere

The models showed that as the troposphere has been expanding, it has been pushing upward on the stratosphere. They also found that as carbon dioxide made its way into the stratosphere, it has had a cooling effect, resulting in a contracting force. The researchers found the net result was a thinning stratosphere. Their calculations showed that the stratosphere has thinned by approximately 400 meters since the 1980s, which translates to approximately 1% of its thickness. Running the models forward showed that the stratosphere will continue thinning as long as greenhouse gasses are emitted into the atmosphere. They suggest it could thin by as much as a kilometer in just 60 years. They note that their model also showed that changes to the ozone layer had little impact on thinning of the stratosphere.

The researchers note that it is still not clear what impact a shrinking stratosphere may have on the planet, but note that it could affect the trajectories of satellites and how radio waves propagate, which could eventually have an impact on the Global Positioning System.
