Nuclear power emits much lower greenhouse gas emissions than electricity from coal but there is risk of a reactor accident, unresolved issues with radioactive waste disposal, and weapons.
The energy released from the nucleus of an atom – nuclear energy – is harnessed today by heating water to make steam. The steam turns a turbine that drives a generator to make electricity.
Global warming has slowed a little over the past decade or so, but nobody with a clue about climate change thinks this means the problem has gone away
Carbon capture and sequestration or CCS is a technology that can remove carbon dioxide emitted by a power plant and store it underground. Climate Central visits the site of a proposed coal plant in Linden, NJ to find out how it is done.
The phrases "global warming" and "climate change" are technically different, but the way most people use them - including lots of climate scientists - they mean pretty much the same thing.
When scientists look at climate variations in the past, they don't see anything like today's warming.
It's why global warming is happening, and why scientists are so worried about rising levels of carbon dioxide and other gases generated by agriculture, transportation and industry
Just before the last Ice Age, temperatures were 5 to 9° F warmer than today, and global sea level was 13 to 20 feet higher. In July 2009, Climate Central traveled to Greenland to visit scientists drilling into ancient ice for clues about this chapter of the past, and what it might say about the potential effects of global warming this century.
