NASA/NSIDC: 2016 Arctic sea ice wintertime extent hits another record low

  2016 Arctic sea ice wintertime extent hits another record low By Maria-Jose Viñas, NASA’s Earth Science News Team Excerpt Arctic sea ice appears to have reached a record low wintertime maximum extent for the second year in a row, according to scientists at the NASA-supported National Snow and Ice Data Center (NSIDC) and NASA.…

A potential future world scenario, driven by rapid regional changes

As someone who follows the climate topic for several years, I’ve to conclude that we are still far away from taking climate change seriously. Around 10 years ago there were rather minor groups of concerned scientists and bloggers, while the media was giving “a balanced view” to the so called deniersphere. This went on for…

Arctic Sea Ice Reaches 2015 Minimum Extent

Arctic Sea Ice Summertime Minimum Is Fourth Lowest on Record According to a NASA analysis of satellite data, the 2015 Arctic sea ice minimum extent is the fourth lowest on record since observations from space began. The analysis by NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado…

NASA, NOAA Find 2014 Warmest Year in Modern Record

The year 2014 ranks as Earth’s warmest since 1880, according to two separate analyses by NASA and National Oceanic and Atmospheric Administration (NOAA) scientists. The 10 warmest years in the instrumental record, with the exception of 1998, have now occurred since 2000. This trend continues a long-term warming of the planet, according to an analysis…

NASA | 2014 Warmest Year On Record

The year 2014 now ranks as the warmest on record since 1880, according to an analysis by NASA scientists. Nine of the 10 warmest years since modern records began have now occurred since 2000, according to a global temperature analysis by scientists at NASA’s Goddard Institute for Space Studies in New York. 2014’s record-breaking warmth…

Novel climate proxy reveals CO2 content of Earth’s atmosphere, of the past 400 million years

The study New constraints on atmospheric CO2 concentration for the Phanerozoic (DOI: 10.1002/2014GL060457), by Peter J. Franks, Dana L. Royer, David J. Beerling , Peter K. Van de Water, David J. Cantrill, Margaret M. Barbour, and Joseph A. Berry, estimates CO2 in Earth history based on a new climate proxy. Estimates are in particular based…

Time history of atmospheric carbon dioxide (2013 data)

Video credit: Andy Jacobson, CIRES/NOAA In 2013, Greenhouse gases continued to rise, 34 percent increase since 1990 NOAA reported in May 2014, about greenhouse gas observations, based on the Annual Greenhouse Gas Index (AGGI). Findings show that greenhouse gasses keep rising, a trend observed since the Industrial Revolution (1880s) and has accelerated in recent decades. The main contributor…

Why is Antarctic sea ice expanding?

By Laura Naranjo (NSIDC), first published January 31, 2014. In the following  an edited version, reposted here with permission. Antarctic sea ice is ruled by very different systems than Arctic sea ice. The reasons behind this increase are complex, and several recent studies show that scientists are still trying to understand them. Ice and wind Atmospheric…

UK Floods 2014 Could Last for Months + 1.6M Homes at Risk for Flooding

Andy McKenzie, a groundwater scientist at the British Geological Survey, told Sky News that even if the rain stopped today, so much water is soaking through the soil that levels are likely to keep rising for another two months. The risk of flooding could remain high until May, he said. According to the data from the…

2013 was the second-hottest year without an El Niño since before 1850

The Guardian: According to the global surface temperate data set compiled by Kevin Cowtan and Robert Way, which achieves the best coverage of the rapidly-warming Arctic by filling in data gaps between temperature stations using a statistical method called kriging, 2013 was the 5th-hottest year on record (since 1850). The top three hottest years (2010, 2005,…

Extensive ice in Antarctica

Released by National Snow and Ice Data Center | Access date January 4, 2013. While it is early winter in the Arctic, it is early summer in the Antarctic. Continuing patterns seen in recent years, Antarctic sea ice extent remains unusually high, near or above previous daily maximum values for each day in November. Sea ice…

Chris Hayes & Michael E Mann: There’s Global Warming – And It’s Snowing

Chris Hayes from MSNBC talks to Michael E Mann about global warming deniers and the season we call “winter.” Release with full segment URL Chris Mooney in MotherJones: 1. Statements about climate trends must be based on, er, trends. Not individual events or occurrences. Weather is not climate, and anecdotes are not statistics. 2. Global warming is actually…
