We're running the most dangerous experiment in history right now, which is to see how much carbon dioxide the atmosphere... can handle before there is an environmental catastrophe.
Sentiment: NEGATIVE
If we emit massive quantities of untested chemicals into the environment, some of them are bound to end up in places that surprise us, doing things that endanger us.
Despite all the progress climate scientists have made in understanding the risks we run by loading the atmosphere with CO2, the world is still as addicted to fossil fuels as ever.
Even if producing CO2 was good for the environment, given that we're going to run out of hydrocarbons, we need to find some sustainable means of operating.
We now know that we cannot continue to put ever-increasing amounts of CO2 into the atmosphere. Actions have consequences. In fact, the consequences of past actions are already in the pipeline. Global temperatures are rising. Glaciers are melting. Sea levels are rising. Extreme weather events are multiplying.
Decades of scientific research has proven that carbon pollution is harmful to human health and causes global warming.
I think there's plenty of evidence that we need to stop spewing so much carbon into the air, that we're contributing to climate change and that we ought to look for alternatives.
We run enormous risks and we know what kind of reductions of greenhouse gases are necessary to drastically reduce risks. Reducing emissions by half by 2050 is roughly in the right ballpark. It would bring us below 550 ppm.
I'm not a scientist. If there is a risk to our environment, there will be no fracking.
The sooner we get started with alternative energy sources and recognize that fossil fuels makes us less secure as a nation, and more dangerous as a planet, the better off we'll be.
Loads of chemicals and hazardous wastes have been introduced into the atmosphere that didn't even exist in 1948. The environmental condition of the planet is far worse than it was 42 years ago.
