Last year was Earth's warmest on record, separate reports by NASA and the National Oceanic and Atmospheric Administration released on Friday showed.

With the exception of 1998, the 10 warmest years on record have now occurred since the year 2000, according to analysis of surface temperature measurements by NASA and NOAA.
NASA said since 1880, when record-keeping began, Earth’s average surface temperature has warmed by about 1.4 degrees Fahrenheit (0.8 degrees Celsius), a trend that is largely driven by the increase in carbon dioxide and other human emissions into the planet’s atmosphere. Published on Jan 16, 2015

Climate science explained in 60 seconds by the Royal Society and the US National Academy of Sciences.

During the last 200 years, human activities such as the burning of fossil fuels have increased concentrations of CO2 in the atmosphere by 40%. If unchecked, continuing emissions will warm up the planet by 2.6°C to 4.8°C by the end of this century. This would have serious implications for human societies and the natural world.

This 60-second animation from the world's two leading science academies brings you the science behind climate change. Published on Dec 10, 2014

Arctic Emergency: Scientists Speak On Melting Ice and Global Impacts. This film by Max Wilbert brings you the voices of climate scientists - in their own words.

Rising temperatures in the Arctic are contributing the melting sea ice, thawing permafrost, and destabilization of a system that has been called "Earth's Air Conditioner".

Global warming is here and is impacting weather patterns, natural systems, and human life around the world - and the Arctic is central to these impacts. Published on Aug 1, 2014

An ultra-high-resolution NASA computer model has given scientists a stunning new look at how carbon dioxide in the atmosphere travels around the globe. Very interesting.

Plumes of carbon dioxide in the simulation swirl and shift as winds disperse the greenhouse gas away from its sources. The simulation also illustrates differences in carbon dioxide levels in the northern and southern hemispheres and distinct swings in global carbon dioxide concentrations as the growth cycle of plants and trees changes with the seasons.

The carbon dioxide visualization was produced by a computer model called GEOS-5, created by scientists at NASA Goddard Space Flight Center’s Global Modeling and Assimilation Office.

The visualization is a product of a simulation called a “Nature Run.” The Nature Run ingests real data on atmospheric conditions and the emission of greenhouse gases and both natural and man-made particulates. The model is then left to run on its own and simulate the natural behavior of the Earth’s atmosphere. This Nature Run simulates January 2006 through December 2006.

While Goddard scientists worked with a “beta” version of the Nature Run internally for several years, they released this updated, improved version to the scientific community for the first time in the fall of 2014.
