Environmental effects: It's our doing"Because the rates of emissions are growing, it looks like we could burn through the other half in the next 25 years" under one of the more dire scenarios outlined in the report. Other scenarios show that the threshold will be reached later this century. The finding constitutes a warning to governments to cut emissions of carbon dioxide, the main greenhouse gas, which is generated by the burning of fossil fuels, industrial activity and deforestation. Calling climate change "the greatest challenge of our time," panel co-chair Thomas Stocker said humankind's fate in the next 100 years "depends crucially on how much carbon dioxide will be emitted in the future". In the report, the panel said it is 95% certain that human activity is the dominant cause of the global warming observed since the 1950s. That is up from 90% six years ago. "Human influence has been detected in warming of the atmosphere and the ocean, in changes in the global water cycle, in reductions in snow and ice, in global mean sea level rise, and in changes in some climate extremes," the report said. The report is the panel's fifth major assessment since 1990. It reaffirms many of the conclusions of past reports, but with greater confidence. "The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, sea level has risen and the concentrations of greenhouse gases have increased," the panel wrote in a 36-page summary of its findings.

Not often carry out nuclear industry executives and hardline activists who be against them agree on anything. Mutually the two hates the thought of continuing to stockpile highly radioactive waste the reactor cores of nuclear power plants on the site of each power-generating station. An hour-long hearing held December 2, 2013 drew almost 200 people from Ohio and Michigan to the Hilton Garden Inn in Perrysburg's Levis Commons was a reminder that both sides are still far apart on what the government's next step should be. Although it would mean putting up with the waste decades longer than expected, industry and trade unions eventually want a single, national repository. Failure to develop a solution is reason enough to shut down the industry; this is the antinuclear activists claim to the government. Nuclear power provides 20 percent of America's electricity. The Nuclear Regulatory Commission, the government agency that oversees the nuclear industry, learned a lot of information, the 11th stop on the agency's 12-city tour in which it ought to do just that: Get a cross section of opinions. As an answer to the government's decision to unfinished plans for a national repository in Nevada's Yucca Mountain, the NRC has been asking Americans about their thoughts regarding the agency's proposed "waste confidence" rule and its affiliated environmental impact statement,. As a consequence, the NRC is inquiring what the public's thoughts concerning leaving the waste where it is, at least for the time being.
