The Welsh Ice Cap Interaction
The following Google Earth animation is an ‘optimal’ numerical reconstruction of the Late Devensian Welsh Ice Cap, derived in the publication ‘The last Welsh Ice Cap: Part 1′. Timeslices of the ice-surface velocity begin at 27.8 ka BP and refresh every 200 years. To view properly: Make sure the time slider is zoomed out to [...]
Read moreNext Ice Age on hold
A study recently published in Nature Geoscience has suggested that due to current atmospheric concentrations of CO2, the next ice age will fail to materialise on time. The authors used past interglacials as analogies to the present, and by assuming that ice growth mainly responds to insolation and CO2 forcing predicted our current warm period would end [...]
Read moreA new Arctic sea ice record?
Measurements taken from NASA’s Aqua satellite have shown that the area covered be sea ice in the Arctic Ocean this year came narrowly close to the record low set in 2007, according to the National Snow and Ice Data Center (NSIDC). The animation below shows how sea ice cover has changed since early March until [...]

A paper recently published in the journal Remote Sensing has found that observations made by NASA’s Terra satellite in fact contradict a number of assumptions fed into alarmist computer models, including those of the United Nation’s IPCC. Dr. Roy Spencer used data from between 2000 through to 2011 to show that the Earth’s atmosphere is far [...]
Read moreThe Welsh Ice Cap
During the last glacial maximum ~20 thousand years ago, Britain and Ireland became engulfed by a large and dynamic ice sheet. Wales played an important part, hosting its own semi-independent ice cap with accumulation centres located on Snowdonia, the Cambrian Mountains and the Brecon Beacons. Ice is thought to have covered all summits in Wales, [...]
Read moreArctic sea ice at record January low
Analysis from the National Snow and Ice Data Center has shown that Arctic sea ice averaged over January 2011 covered 13.55 million km² – the lowest January ice extent recorded since satellite records began in 1979. This figure lies 1.27 million km² below the long term average between 1979-2000, adding to the linear rate of [...]
Read moreSnowfalls a thing of the past?
…or so Charles Onians thought so in 2000. His article in The Independent reported that the increased temperatures observed during the 1990′s meant that snow would soon ‘disappear from our lives’. Although funny in hindsight, the article is not supported with any science, and really shows how the press warp the whole global warming debate [...]
