"A NASA science team has observed "amazing and potentially troubling" levels of methane and CO2 from the rapidly warming Arctic. Given the staggering amount of carbon trapped in the permafrost - and the fact that methane is a very potent heat-trapping gas - the space agency is now asking: "Is a Sleeping Climate Giant Stirring in the Arctic?""

"An analysis of global temperatures by NASA scientists shows that 2013 was the seventh warmest year since 1880 (tied with 2006 and 2009). Nine of the 10 warmest years on record all have occurred since 2000, with 2010 and 2005 ranking as the warmest. Scientists at NASA's Goddard Institute for Space Studies (GISS) reported that 2013 continued the long-term trend of rising air temperatures over the land and sea surface. This animation shows monthly temperature anomalies from 1880 through 2013."

Each week NASA's State of Flux website features images of different locations, showing the effects of climate change, urbanization, or natural hazards such as fires and floods. If you select the 'map view' option you can view a Google Map of all the locations so far covered. If you then select a marker on the map you can view two images of the location that have been taken at different times. If you scroll to the bottom of the page you can also find a number of links to browse the images by different categories, such as 'extreme events', 'human impacts' and 'top picks'.

"The Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era - and of human civilization. Most of these climate changes are attributed to very small variations in Earth's orbit that change the amount of solar energy our planet receives."

"Recently NASA reported that this year's maximum wintertime extent of Antarctic sea ice was the largest on record, even greater than the previous year's record. This is understandably at odds with the public's perception of how polar ice should respond to a warming climate, given the dramatic headlines of severe decline in Arctic summertime extent. But the "paradox of Antarctic sea ice" has been on climate scientists' minds for some time."

Climate Kids is NASA's climate change website for kids. On Climate Kids you will find a nice selection of online games and hands-on activities for students. Some of the topics that the Climate Kids online games address include recycling, renewable energy, and climate history.

Good one - thanks, John! m
