It is not the first time that life on Earth has threatened its own existence. More than 2 billion years ago, photosynthesis by ocean cyanobacteria emitted massive amounts of molecular oxygen into the atmosphere. Known as the Great Oxygenation Event , it caused major cooling and glaciation of the Earth’s surface. It also drove evolution of species towards greater diversity and complexity that created the homo sapiens. Humans began polluting their environment on a massive scale during the Industrial Revolution . By the end of the 19th century the use of coal and heavy machinery made many workplaces hazardous. Areas around factories became unlivable. Besides affecting people’s health, the air filled with particles and chemicals created problems for industries. Printing, food and textile production suffered most. This, however, did not stop technological progress. It resulted in the invention of the air conditioner . Can we air condition Earth instead of reducing our energy … [Read more...] about Climate change: Can humans be the Earth’s air conditioner?

Secretary Buttigieg’s recent testimony in front of Congress describes a different future for America’s transportation , one that improves the air we breathe. This testimony comes weeks after pledges by the giants of the auto industry to vastly increase their production of electric vehicles (EV) over the next five years. Carrying out these pledges sets the stage for a breakthrough in public health. Phasing out gasoline-powered cars will be a slow process and, honestly, much more aggressive policy is needed to reap the health benefits of electrification. It is highly likely, however, that in 30 years we will look back at gasoline-powered cars the same way we now look at cars with no seatbelts and wonder why there was such a debate about making the change to EVs. As an ear, nose and throat doctor, I see patients whose breathing is worsened by air pollution. While politics may not belong in the exam room, policy that impacts health does. I, along with thousands of other health … [Read more...] about In the ’80s it was seatbelts, now doctors are pushing for electric cars
Colorado is a national leader in renewable energy and fighting human-caused climate change. In 2004, clean energy advocates and environmentalists took Amendment 37 to the ballot, establishing a 10% renewable energy standard, and won. The amendment mandated that by 2015, 10% of Colorado’s energy needed to come from renewable sources. Former Gov. Bill Ritter heralded its passage as the beginning of the “New Energy Economy,” and made it a centerpiece of his successful campaign for governor in 2006. Since that landmark ballot initiative passed, giving Colorado the first voter-approved renewable energy standard in the country, we’ve increased it to 30%. Xcel Energy, the state’s largest utility, was also the largest funder opposing Amendment 37 in 2004. Xcel changed their tune and has now set its own goal to be 100% carbon free by 2050. But energy isn’t the whole story when it comes to climate change. Ensuring that we quickly and aggressively reduce greenhouse gas emissions in all … [Read more...] about Silverii: Efforts to reduce greenhouse gases need the force of law
