How warm periods in earth's history have impacted sea-level rise

9/1/2017

0 Comments

 
I wrote a new post for EGU's Cryosphere blog looking at how warm periods in Earth's history (due to Earth's climate cycles) have impacted the melt of the polar ice sheets and changed sea-level rise.  Feel free to check it out below:

New publication on glacial lake outburst flood hazard and risk in nepal

6/30/2017

A study that I conducted with Scott Watson (University of Leeds) and Daene McKinney has recently been published in the journal of Remote Sensing.  The study assesses the hazard and risk associated with all of the sizable (> 0.1 km2) glacial lakes in Nepal.  First, it seeks to determine how susceptible glacial lakes are to avalanches, rockfalls, and upstream floods in addition to assessing how stable the moraine is using a surrogate parameter.  These are the most common triggering mechanisms that cause an outburst flood to occur.  Then,  the areal extent of each flood was also conservatively modeled, and the downstream impacts were quantified.  Take a look at the following website:

One of my good friends, Tim Ager, did just that last year as a research scientist!  He had some truly fascinating experiences that I was able to write in an interview with him that's been posted on the EGU cryosphere blog.  Have a look!

You may recall from the Imja blog last summer that we witnessed a glacier outburst flood on 12 June 2016 and spent our subsequent days retracing the flood's path and trying to find its source.  Well all that hard work paid off today as our research efforts were published in The Cryosphere!  Special thanks to our research team: Alton Byers, Elizabeth Byers, Daene McKinney, and all those others who joined us!  You can read it for free here:

Or you can simply check out the video. Enjoy!

I always thought presentations with little videos looked great, but didn't know how to make them... I played around with gifmaker.me (easy to use) today and here was the result.  Pretty nice graphic of Imja's growth from 2000 to 2016!
