Expert explains Future Sea Level Rise (2017)

Eric Rignot (NASA/JPL) one of the world’s most prominent glaciologists, who is behind a landmark report revealing the unstoppable collapse of a large part of Antarctica, gave a lecture at Victoria University of Wellington in February 2017, on future sea level rise.

Greenland Melt contributes to Sea Level Rise

Using satellite and field work after an extreme melt event in Greenland, a UCLA-led study finds that melt-prone areas on its ice sheet develop a remarkably efficient drainage system of stunning blue streams and rivers that carry meltwater into moulins (sinkholes) and ultimately the ocean. However, the team’s measurements at the ice’s edge show that…

Study: Human fingerprint found on global extreme weather

Global warming makes temperature patterns that cause heatwaves, droughts and floods across Europe, north America and Asia more likely, scientists find Study Influence of Anthropogenic Climate Change on Planetary Wave Resonance and Extreme Weather Events http://www.nature.com/articles/srep45242 Further reading https://www.theguardian.com/environment/2017/mar/27/climate-change-human-fingerprint-found-on-global-extreme-weather

Arctic and Antarctic sea ice at lowest since satellites began to measure 1979

Sea Ice Extent Sinks to Record Lows at Both Poles Arctic sea ice appears to have reached on March 7 a record low wintertime maximum extent, according to scientists at NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) in Boulder, Colorado. And on the opposite side of the planet, on March 3…

Potential abrupt cataclysmic change and the Atlantic

A slowdown or even collapse of the Gulf Stream System as a result of global warming has long been a concern of climate scientists and has fuelled the imagination of Hollywood. Recent studies provide evidence for a AMOC slowdown.

Study: Contribution of Antarctica to past and future sea-level rise (2016)

A study published in March 2016, suggests that large parts of East Antarctica’s ice sheet can collapse, can do so under Pliocene conditions. A key question has long been whether ice sheet contribution could accelerate substantially, by an order of magnitude, either in this century or subsequently. Until recently ice sheet models had problems to…

Jim Hansen: Hell Will Break Loose – Ice Melt, Sea Level Rise and Superstorms

The main point that I want to make concerns the threat of irreparable harm, which I feel we have not communicated well enough to people who most need to know, the public and policymakers. I’m not sure how we can do that better, but I comment on it at the end of this transcript. In…
