The World’s Leading Climate Scientists Have Spoken Again

The IPCC (Intergovernmental Panel on Climate Change) Working Group I, the world’s leading climate scientists, released its final report on January 30, 2014 “Climate Change 2013: The Physical Science Basis”.  There are no surprises here – the earth is warming at an alarming rate due in large part to humans burning fossil fuels.  Let’s take a quick look at the highlights – the following are the Headline Statements from the Summary for Policymakers (http://www.climate2013.org/spm);

·         “Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia. 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.

·         Total radiative forcing is positive, and has led to an uptake of energy by the climate system. The largest contribution to total radiative forcing is caused by the increase in the atmospheric concentration of CO2 since 1750.

·         Human influence on the climate system is clear. This is evident from the increasing greenhouse gas concentrations in the atmosphere, positive radiative forcing, observed warming, and understanding of the climate system.

·         Continued emissions of greenhouse gases will cause further warming and changes in all components of the climate system. Limiting climate change will require substantial and sustained reductions of greenhouse gas emissions.”

The world needs to respond and the United States should be taking the lead.  The science is clear, there is no more time for debate.

    So is there any evidence that the earth has had previous ” warm ups” ?

    While man can have a small impact , why couldn’t this be mostly part of normal climate change ?

    How do they explain the very cold and snowy winter we are having ? Is getting a very COLD snowy winter part of ” warming up” ?

    I think the earth is much more resilient than we give it credit for. Look at the oil spill in the Gulf of Mexico. Originally it was going to take many years for it to go back to normal. But instead it took about a year ?

    I have no problem wanting to reduce emissions , recycle and conserve. But let’s not go off of the deep end on this.

    To proclaim there is no more time for debate seems odd coming from a science community. No inclusion of looking at all sides? That obvious strong arm technique that debate is over shows your agenda. By definition, even just by their name, the IPCC has to meet goals set by one side not others. Last I checked there has been no warming in the last 17 years and just since the late 1970’s I don’t think we’re headed toward the next ice age.

    India and China average building one coal energy plant PER WEEK. Why should we take the lead? Our output is peanuts compared to many other nations. Oh wait, follow the money, you cant drain wealth out of India and China like you can from the “greedy Americans”. Whole argument is a haox for more tax and control.

    You could have just posted this from months ago.

    I’d be surprised if you posted this, but it doesnt take long to catch on the the agenda just getting passed down the lines month after month.
