A Loss of more than just Agriculture

           Robin McKie, a science editor for the Observer, part of the Guardian, recently released an article entitled 'Climate Change 'will make hundred of millions homeless'' informing us of the carbon dioxide levels indicating a rise in temperatures leading to continental agricultural failure.  He tells us that millions will eventually be displaced from their current homes as an effect of global warming and climate change.  Temperatures are likely to rise up at 5 degrees Celsius which will cause a disruption in normal weather patterns including precipitation and drought.  There has been news of carbon dioxide levels reaching an astonishing 400 parts per million (ppm) with rates rising since the 1960's, now at 2.1 ppm/year.  Eventually these rising carbon dioxide emissions will create a feedback loop of rising temperatures to melting ice to loosing coastal lands and so on and so forth.  Changes need to happen and they need to happen soon.

Climate Models

    There are many different climate models and simulations that are made as future predictions to see how our everyday global choices will affect the future climate.  Different parameters are used and varied throughout trials to see how changes will play out through the years. Chapter 9 of Climate Change 2001: The Scientific Basis is all about projections of future climate change.  Throughout the chapter there is a review of past reports and how well they predicted the future as well as climate forcing and climate responses.  Later on there are a multitude of projections of climate change that were made with various models and variables.  Finally there is a summary of what the predictions for the future are as well as their appendix and references.

The New Climate

     Kevin Trenberth is as senior scientist in the Climate Analysis Section at the National Center for Atmospheric Research.  He is prominent in climate variability and climate change research, as well as a leader in the Intergovernmental Panel on Climate Change assessments.  He is also in the World Climate Research Programme.  He is an advocate for the need to develop a climate information system for the adaption to climate change.
     In this clip (2012) Trenberth talks about how the southwestern parts of the United States have been unusally dry in regards to the amount of wildfires that are taking place.  He also talks about the fact that there is no snow left much earlier than usual, which is attributing to the heat wave that has been building throughout the year.
