Summary: Access outlook maps showing experts' judgments of chances for above-, below-, or near-average temperature and precipitation for a range of future periods. Maps also show potential hazards and conditions related to drought.

Summary: As the climate changes, populations of mosquitos, ticks, and other disease vectors may increase, survive longer, and expand into new areas when temperatures rise.

Summary: Rising temperatures and more frequent heavy precipitation events can exacerbate food and water safety risks, resulting in more frequent pathogen-related disease outbreaks, less effective water treatment, and increased exposure to contaminants.

The annual minimum was 5.02 million square kilometers (1.94 million square miles), making 2014 the sixth smallest extent in the satellite era, which began in 1979.

A new paper: "Modeling regional aerosol variability over California and its sensitivity to emissions and long-range transport during the 2010 CalNex and CARES campaigns," has been published in the ... ...

August 2014's globally averaged surface temperature and sea surface temperatures both set new records.

As of late August 2014, tropical atmospheric temperatures appear to be responding more strongly to the ocean than they typically do at this early stage of El Niño development.   

Natural variability can explain much of Earth's average temperature variation since the end of the last ice age, but over the past century, global average temperature has risen from near the coldest to the warmest levels in the past 11,300 years.

Temperature extremes have been pretty unusual across the United States so far in 2014. Looking back over this time period quickly reveals at least part of what was going on: the polar jet stream got into a serious rut.

New research titled: "Observational evidence for interhemispheric hydorxyl parity," appeared in the Sept. 11 issue of Nature. The research, which is about the abundance of the hydroxyl radical on ... ...
