reflections from an expedition: delaney graham

i’ve never felt so small. seeing natural skyscrapers in every direction can do that to a person. the first day at sea we went into tracy arm fjord and saw south sawyer glacier. and i didn’t realize how massive the rock walls around us were until i saw a zodiac next to them. we were stopped in our zodiac looking at the glacier when our naturalist pointed out another zodiac with 8 or so passengers at the base of one of the slabs of rock face. and i needed a naturalist to point it out, my eyes passed right over the boat which looked no bigger than an ant. at that moment my stomach dropped, i was able to contextualize and better comprehend what i was seeing. the zodiac was several miles away looking up at walls over a mile high. from that point forward everything i looked at made me wonder how massive it would seem if i had a scale to compare it to. to make my little animal brain understand the majesty of alaska.

it felt nice to feel so small. everyday i’m the center of my world, and it’s easy to get caught up in everything i have going on. but to feel tiny and insignificant gave me the freedom to slow down and take a breath. to walk through a forest that predates glaciers really puts my little life in perspective. and it feels so good to get lost in the wilderness (metaphorically, hopefully never literally). alaska is a place to go to lose yourself, and i think eventually find yourself.

cop26 in context: grassroots climate change communication, sea ice, and urban inequality

tue, 02 nov 2021 15:11:42 +0000

today is day three of cop26, a key climate summit in glasgow attended by delegates from 197 countries. tuesday’s schedule will cover themes of grassroots climate change communication, sea ice, and urban inequality. want to know more? we’ve got you covered.

step by step guide to having a conversation about climate change. the foundation for environmental education held a panel at cop26 today about the power of communication networks. learn about communication networks, why they’re so important, and how to start a conversation about climate change yourself!
five facts from nasa to help you understand sea ice. changes in sea ice play a key part in the global climate and have great effects on the ocean.
five big ideas to address the climate crisis and inequality in cities. another panel held today covers urban inequality in the fight for global climate justice. we have a ways to go, but so much is already being done to combat the disproportionate effects of climate change. read about what’s happening in nairobi, kenya; london; rosario, argentina; monterrey, mexico; and ahmedabad, india.

check back tomorrow for more info on what is being explored at cop26 — and good reads to keep you informed!

embedded sea ice model with tidal forcing may improve climate projections

mon, 14 nov 2011 15:26:16 +0000

university of alaska researchers developed a numerical model of the ice-covered arctic ocean that includes tides. they used a highly innovative approach that embeds the sea ice directly into the ocean model. the results of the model compare favorably with observations when contrasted to similar comparisons with more coventional modeling efforts. these results are important because improved modeling of the rapid openings and closings of fractures in the sea ice may improve our ability to model arctic processes such as heat and moisture flux from the sea to the atmosphere, the growth of new sea ice, and the generation of brine from growing sea ice. the findings further establish the nation as a global leader in fundamental and transformational science and engineering.
