Study: We’re already in the ‘worst case scenario’ for sea level rise

By Ari Phillips 10 July 2015 (Climate Progress) – A major new analysis on the impact melting polar ice sheets could have on sea level rise has given rise to some worrisome conclusions. Researchers found that sea levels increased some 20 feet during three warming periods of 1.8 to 3.6°F (1 to 2°C) that took […]

Iceberg influx into Atlantic during last ice age raised tropical methane emissions

By Rachael Rhodes28 May 2015 CORVALLIS, Oregon (OSU) – A new study shows how huge influxes of fresh water into the North Atlantic Ocean from icebergs calving off North America during the last ice age had an unexpected effect – they increased the production of methane in the tropical wetlands. Usually increases in methane levels […]

Sea levels are rising at faster clip as polar melt accelerates, new study shows

By Joby Warrick11 May 2015 (Washington Post) – Global sea levels are climbing at a faster rate than previously thought, according to a new analysis that underscores scientists’ concerns about the impact of melting glaciers and ice sheets near the Earth’s poles. The new research published Monday in the journal Nature Climate Change shows that […]

Greenland Ice Sheet more vulnerable to climate change than previously thought – ‘Extreme meteorological events, such as heavy rainfall and heat waves, can have a large effect on the rate of ice loss’

Contact: Sarah Collinssarah.collins@admin.cam.ac.uk44-012-233-32300University of Cambridge@Cambridge_Uni29 September 2014 (University of Cambridge) – A new model developed by researchers at the University of Cambridge has shown that despite its apparent stability, the massive ice sheet covering most of Greenland is more sensitive to climate change than earlier estimates have suggested, which would accelerate the rising sea levels […]

Greenland ice loss doubles from late 2000s – Greenland and Antarctica together are losing 500 cubic kilometers of ice each year – ‘To us, that’s an incredible number’

By Jonathan Amos20 August 2014  (BBC News) – A new assessment from Europe’s CryoSat spacecraft shows Greenland to be losing about 375 cu km of ice each year. Added to the discharges coming from Antarctica, it means Earth’s two big ice sheets are now dumping roughly 500 cu km of ice in the oceans annually. […]

Doubling of Antarctic ice loss revealed by European satellite – Continent shedding 160 billion tons per year

By Damian Carrington    19 May 2014 (theguardian.com) – Antarctica is shedding 160 billion tonnes a year of ice into the ocean, twice the amount of a few years ago, according to new satellite observations. The ice loss is adding to the rising sea levels driven by climate change and even east Antarctica is now losing […]

Catastrophic collapse of West Antarctic Ice Sheet begins – ‘These glaciers will keep retreating for decades and even centuries to come and we can’t stop it’

By By Becky Oskin, Senior Writer 12 May 2014 (LiveScience.com) – The biggest glaciers in West Antarctica are hemorrhaging ice without any way to stem the loss, according to two independent studies. The unstoppable retreat is the likely start of a long-feared domino effect that could cause the entire ice sheet to melt, whether or […]

New Antarctic ice shelf threatened by warming – Melting Filchner-Ronne shelf could add 4.4 mm per year to rising global sea levels

By Chris Wickham; Editing by Janet Lawrence9 May 2012 LONDON (Reuters) – Scientists are predicting the disappearance of another vast ice shelf in Antarctica by the end of the century that will accelerate rising sea levels. The Filchner-Ronne Ice Shelf fringing the Weddell Sea on the eastern side of Antarctica has so far not seen […]

Carolyn Baker: What does it mean to ‘do something’ about climate change?

There is a great difference between being still and doing nothing. ~Chinese proverb~ By Carolyn Baker16 April, 2014 (Carolynbaker.net) – When I speak about catastrophic climate change and the likelihood of near-term human extinction, I am often accused to “giving up” or choosing to “do nothing” about climate change. Even more charged for some is […]

Earth’s poles are shifting because of climate change

By Anil Ananthaswamy13 December 2013 (New Scientist) – Climate change is causing the North Pole’s location to drift, owing to subtle changes in Earth’s rotation that result from the melting of glaciers and ice sheets. The finding suggests that monitoring the position of the pole could become a new tool for tracking global warming. Computer […]
