@NektariosH This is a great source! I referenced their work many times in my synthesis!

[selena @SelenaaaXie]

@KristaEin1 I’m really looking forward to doing nothing during winter break. All my plans will have to come after!

[selena @SelenaaaXie]

I can’t believe this is my last Tweet for #ENVIR492! Best wishes for everyone graduating this quarter and congrats to everyone! Also, good luck to those in #ENVIR490, I’m sure your projects will turn out amazing. I can’t wait to come back and see them!

[selena @SelenaaaXie]

#ENVIR492 Tomorrow is the last day of lecture! How many finals/projects does everyone have left to do? I feel like I have a million...

[selena @SelenaaaXie]

@KristaEin1 Definitely! I am sad that we have never met as a group but I think we did amazing!

#FutureOfSnowAndIce This group are called Mandt's black guillemots, which are different than the ones found in Maine or Canada. They were thought to be trapped in the Arctic basin in the last Ice Age and evolved to live in icy conditions.

[selena @SelenaaaXie]

#FutureOfSnowAndIce Without ice, the Black Guillemots chicks are dying before the 35-day nesting period because of less food. In 2012, polar bear presence has increased, which increased threat to chicks.

#FutureOfSnowAndIce Our new speaker is George Divoky, who studies an ice-adapted group of seabirds in Cooper Island currently experiencing difficulties as ice melted

#FutureOfSnowAndIce Dr. Armour once spoke at #PolarBearInternational, who puts together talks by scientists to elementary school kids about #climatescience.

#FutureOfSnowAndIce Lake waters are fresh water, the water is warmer on top. In Polar regions, the water is cold at the top and becomes warmer as you go down because of higher salt concentrations.

[selena @SelenaaaXie]

#FutureOfSnowAndIce There are "floats" in the ocean measures salinity, temperature, etc. These and satellites show warming occurring much faster in the Arctic than the Antarctic. The current hypothesis is because of differences ocean circulations.

#FutureOfSnowAndIce The IPCC brings together volunteer scientists to write non-policy reports, receives feedback from the public, and gives the report to policy-makers to determine what policies should be implemented.

Dr. Armour is in working group 1: https://t.co/sq1QicoFm2

[selena @SelenaaaXie]

#FutureOfSnowAndIce Dr. Armour also works with the IPCC on writing assessment reports. Here is the link for the official websites: https://t.co/2pkvboHTPR
It is amazing to hear that they are focused on getting opinions from scientists.

#FutureOfSnowAndIce My next speaker from the Science Roulette is Kyle Armour at @UW studying the physical sciences of climate change in the polar regions!

[selena @SelenaaaXie]

#FutureOfSnowAndIce Richard Byrd was the first American to realize there was strategic value in exploring Antarctica! Since then, the US has a clear area, not claimed, of the Antarctica to conduct science research. The US's presence in Antarctica is 10x of other countries.

Oops *layer of ice!

[selena @SelenaaaXie]

#FutureOfSnowAndIce The longest continuous later of ice tells the story of 8000 years. Within the ice, there was evidence of 8 periods of warming and cooling.

[selena @SelenaaaXie]

#FutureOfSnowAndIce As ocean freezes, the salt gets pushed down and a less salty ice sheet forms on top. This is very thin, which is why most of the melting in Antarctica is from sea ice, not land ice!

[selena @SelenaaaXie]

#FutureOfSnowAndIce Because of the Arctic vortex , the Arctic warms faster than the rest of the globe.
