As the Earth warms, researchers at the Ice and Climate Exploration Research Center (PSICE) at Pennsylvania State University are interested in how we can expect glaciers, those dense bodies of ice that move under their own weight, to react to a drastically changing environment.<\/span><\/p>\n

Extreme hurricanes and floods and increasing wildfires and drought make the impact of climate change increasingly obvious, but what happens to glaciers and ice sheets is important for the future of so many coastal cities that lie in potentially devastating floodplains.<\/span><\/p>\n

Veteran geoscientist Richard Alley of Penn State University revealed a bleak future during the annual Comer Climate Conference this fall, one where a changing climate will affect the Earth and all of its inhabitants, not just humans, at a systemic level. The conference draws scientists from across the world sharing their latest findings and documenting the urgent need to address climate change.<\/span><\/p>\n

Alley said to study climate science is to steep your way into worry and anxiety about the future.<\/span><\/p>\n

But it presents solutions to those very worries as well.<\/span><\/p>\n

\u201cI suspect the students need a sign over the door that says, \u2018We are the ark,\u2019\u201d Alley said. \u201cWe\u2019re going to get through this by preserving (various) species so we can get them back out, \u2019cause some of them are in such deep trouble now and they\u2019re going to need help.\u201d<\/span><\/p>\n

By 2100, projected global sea-level rise could be slowed to a half meter lower than prior projections, but only if global temperature increase is kept at 1.5 degrees Celsius instead of 2 degrees Celsius, according to estimates by the Intergovernmental Panel on Climate Change.<\/span><\/p>\n

Alley considers the projection a modest estimate and seeks, along with his research group, to estimate a worst-case scenario resulting from no climate action.<\/span><\/p>\n

\u201cWe can hope, but I think the biggest thing is to limit CO2 (carbon dioxide), and then as much collateral damage (as possible),\u201d he said.<\/span><\/p>\n

CO2 levels drive global warming from fossil fuel emissions, and many scientists calculate that increasing levels over the past decades are already rolling 2 degrees Celsius of temperature rise into the atmosphere. Alley said that carbon dioxide spells devastating damage for lots of organisms that live in seawater even before those rising tides can impact humans. Marine life is the canary in the cage for the threat to other life.<\/span><\/p>\n

Organisms like coral are subjected to toxic underwater levels of carbon dioxide, and the effort to cultivate nature-resiliency and human-resiliency can only go so far as long as carbon dioxide level continues to rise.<\/span><\/p>\n

\u201cToo much CO2 too fast looks like a really bad prescription for coral reefs,\u201d he said. \u201cIt\u2019s very clear that the more CO2 we put in the air, the harder the task we\u2019re setting to keep the reefs.\u201d<\/span><\/p>\n

Pollution remains a prime catalyst for deadly disease in coral reefs, however.<\/span><\/p>\n

Over the past decade, the reefs have seen a visible change from what they once were. No longer filled with bright colors and thousands of fish, the dying reefs are now dull, muted colors.<\/span><\/p>\n

\u201cIf you\u2019re dumping poisons on the reef,\u00a0 it dies faster, whether that\u2019s your sewage outflow or whether that\u2019s your sunscreen,\u201d Alley said. \u201cKeeping those things off the reef is good.\u201d<\/span><\/p>\n

Alley has studied the great ice sheets to predict future climate and sea level change. He participated in the UN Intergovernmental Panel on Climate Change and was the co-recipient of the 2007 Nobel Peace Prize the IPCC received along with former Vice President Al Gore. Alley was also the first recipient of the Stephen Schneider Award for climate communication.<\/span><\/p>\n

Sierra Melton, a geosciences Ph.D. student of Alley\u2019s, currently focuses her studies on one of the largest glaciers in Greenland, Helheim Glacier. The glacier drains from the Greenland ice sheet straight into a fjord and, upon touching the water, breaks into icebergs. Melton is studying the complex hydrology behind the phenomenon as it is not totally understood by researchers yet.<\/span><\/p>\n

\u201cWith more melting and warming, and glacier collapse, studying Helheim is kind of one way to look into the future where these glaciers might look like,\u201d Melton said.<\/span><\/p>\n

\u201cIt\u2019s really a very interesting glacier because there\u2019s a lot of meltwater, both on the glacier and draining from up the glacier,\u201d she said.<\/span><\/p>\n

Climate change research is the only major avenue Melton ever considered for a career path, long before she started work on large-scale glaciology projects.<\/span><\/p>\n

\u201cI don\u2019t know exactly why, but I was just always concerned about it,\u201d Melton said. \u201cEven for one of my birthdays in elementary school, I asked for donations to the World Wildlife Fund to save the polar bears. So yeah, so I guess I\u2019ve always been concerned about climate change.<\/span><\/p>\n

\u201cI am very concerned about what climate change is going to do for our future. And that\u2019s why I\u2019ve gotten into this work\u201d she said. \u201cAnd I think it does motivate me more than it makes me anxious.\u201d<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
