A deadly gas?

At Watt's Up With That, Paul Driessen writes,
A deadly gas? Carbon dioxide is the Miracle Molecule that enables plants to grow and makes all life on Earth possible. Plants absorb CO2 exhaled by humans and animals, and emitted by burning wood, dung, fossil fuels and biofuels – and then release oxygen that people and wildlife need to survive.

Hundreds of studies demonstrate how slightly higher atmospheric CO2 levels (rising from 0.03% a century ago to 0.04% today) are making crop, forest and grassland plants more drought resistant, helping them grow faster and better, and “greening” vast areas that had been brown and barren. Claims that CO2 has replaced the solar and other powerful natural forces that have always controlled Earth’s climate, and is now causing “dangerous manmade climate change,” are not supported by actual planetary evidence.

...The science marchers forget that President Trump’s actions are in response to eight Obama years of “highly politicized so-called research on climate,” under grants that “anticipated particular scientific outcomes before funding was provided,” Princeton University physicist Dr. Will Happer told me. Real science “is not based on political agendas, belief systems or computer models. It’s based on evidence – and actual observations have found normal icecap fluctuations, seas rising a foot or less per century, drought cycles little different from the twentieth century, and a decline in major landfalling hurricanes.”

...One, cheap, reliable energy improves living standards, saves lives, and supports new technologies and opportunities, with poor families benefitting most. Policies that make energy less accessible and affordable harm the poorest most of all.

Two, fossil fuels have undeniable environmental impacts, but allow us to produce vast amounts of cheap energy from relatively few acres. Replacing those fuels with wind, solar and biofuel energy would require hundreds of millions of acres worldwide that are now cropland or wildlife habitats. Those “eco-friendly” alternatives are actually our least sustainable, most ecologically destructive energy options.

The stakes are too high to let intolerant ideologues continue to control energy policy decisions.

Food for fuel?

brings to our attention a report in the Detroit Free Press:
The multi-billion-dollar U.S. biofuels industry — promoted and expanded for over a decade by the federal government — may be built on a false assumption, according to a new University of Michigan study published today that is sure to stir all sides in the contentious debate over the industry.

Despite their purported advantages, biofuels created from crops such as corn or soybeans cause the emission of more climate change-causing carbon dioxide than gasoline, according to the study from U-M Energy Institute research professor John DeCicco.

The study is the latest salvo in the expanding battle over whether biofuels, and the farmland increasingly devoted to them, are actually providing the environmental and climate benefits many expected.
