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

"Vital Signs: Taking the Pulse of Our Planet" was the theme for NASA's Goddard Space Flight Center's fifteenth installment of its annual lecture and reception sponsored by the Maryland Space Business Roundtable. Published on Oct 23, 2014

Earth is a complex, dynamic system we do not yet fully understand. Like the human body, the Earth system comprises diverse components that interact in complex ways.

On this global tour, scientists lead the viewer through Earth's water cycle, forests and frozen regions as seen through the eyes of NASA's Earth observing satellite fleet. They share a story of how we can make life better today and into the future.

NASA's Earth science program aims to develop a greater understanding of Earth's system and its response to natural or human-induced changes, and to improve predictions of climate, weather and natural disasters.

The lecture features:

Lennard Fisk, Ph.D, Distinguished University Professor of Space Science, University of Michigan
