How can we produce enough energy to live well without creating a level of greenhouse gases that generates an increasingly hostile climate? Alternative energy sources like wind and solar are part of the answer, but it isn’t going to be easy to replace the massive quantities of energy currently derived from non-renewable sources such as coal, natural gas, and oil. As it happens, we live over a screaming-hot furnace which can be used to generate electricity and heat with almost no greenhouse gases and no radioactive waste.… Read the rest “Geothermal, a continuous, renewable, energy source without greenhouse gases or radioactive waste”

The biggest problem is simply the amount of garbage we produce. For example, in 2015, two kilograms (4.4 pounds) of Municipal Solid Waste was generated per citizen of the USA every day (MSW is the fancy name for garbage).… Read the rest “Why we should burn garbage”
“Livestock are responsible for 18 percent of the greenhouse gases that cause global warming more than cars, planes and all other forms of transport put together. It’s official: taking to the roads in an SUV’s got nothing on cattle flatulence . . . “ This is a direct quote from a recent web post of a climate sceptic. It restates a popular meme about climate change, favoured by conservative commentators: that man isn’t the most important agent of global warming, it’s the farting cows, stupid.… Read the rest “We Need to Talk About Methane”
