September Bookends the Warmest 12 Months on Record - NOAA’s latest State of the Climate roundup shows that September marked the 16th month in a row with above-average temperatures for the lower 48 states of the U.S. Both the calendar year and the 12-month period from October 2011 through September 2012 were the warmest on record, and statistics show that it will require an unusually cold October through December period for 2012 to rank anything other than the warmest year.
Different kinds of graphs such as these present how climate change is happening by multiple variables being manipulated. This kind of data is used as evidence for others who are skeptical that climate change is actually happening. It can be seen that trends over years and decades support climate change while daily and monthly trends do not. Climate change is most noticeable on a larger scale.
Record Numbers Grow; Fourth-Warmest June in History - June 2012 was not only the planet's fourth warmest June since record-keeping began in 1880, but also the 36th consecutive June and the 328th month in a row that global temperatures have risen above the 20th century average, reported the National Ocean and Atmospheric Administration (NOAA) on Monday in the agency’s monthly State of the Climate report.
