New Study Finds Algae That Melt Arctic Ice

Courtney Lepping — Thu, 23 Jun 2016 17:24:26 +0000

Not many have heard of the albedo effect, where microorganisms are theorized to be melting the Arctic. This is displayed by pink snow. The researcher Stefanie Lutz published a study about the decline of albedo, or reflection of sunlight on the earth’s surface, in snow and ice caused by pink algae. 40 samples from 21 […]

Climate Change and Accelerating Carbon Loss in the Arctic

Michael Rush — Fri, 25 Mar 2016 13:01:48 +0000

Changing weather patterns are causing Arctic soil to lose carbon at a rapid pace, leading to an outcome that further reinforces global temperature increases and climate change. Research can be found in the scientific journal Climate Change Responses. For what seems like an eternity, shrubs, grasses and other plant species have taken carbon out of the […]

Sea Level Rise Accelerating Due to Climate Change

Benji Jerew — Mon, 19 Jan 2015 14:13:24 +0000

While it has been long known that climate change is effecting sea level rise, it seems that the measurements haven’t been quite accurate over the last century, making recent corrections a cause for alarm. There’s a good reason that “climate change” was previously referred to as “global warming,” because global temperatures are rising. Some have […]

There have been many studies highlighting the warming of the arctic. But how does this relate to humans and how grave is the situation? A recent study has shown the warming of the earth is at its highest rate now than it has been in thousands of years. Temperatures over the Canadian Arctic are the […]

The Power of the Albedo Effect on Global Warming

Leigh Hutchens — Wed, 31 Jul 2013 02:21:44 +0000

Albedo is the percentage of incoming radiation reflected off a surface. The term comes from the Latin word for whiteness. When applied to the Earth, the albedo effect measures how much of the sun’s energy is reflected back into space. The balance between energy absorbed by the earth and energy reflected back into space is […]

Russia Sends Floating Nuclear Power Plants In The Arctic

Mila Luleva — Fri, 12 Jul 2013 11:26:33 +0000

Russia’s nuclear power-generating ships, designed to power offshore oil-drilling platforms in the Arctic, are ready to become fully operational by 2016. The ships will be equipped with KLT-40 reactors that can power 200,000 homes and can be modified to desalinate 240,000 cubic meters of water per day. Each ship will hold two reactors, which together […]

‘Greener’ Arctic Will Cause Raise in Global Temperature, Study Claims

Mila Luleva — Mon, 01 Apr 2013 18:22:39 +0000

According to recent research published in Nature Climate Change earlier this week, The Arctic is about to become ‘greener’ due to global rise in temperatures. The team, led by Richard Pearson, a research scientist at the American Museum of Natural History’s Center for Biodiversity and Conservation, conducted a series of model simulations based on data […]

Polar Ecosystems Affected Differently by Climate Change

Mila Luleva — Tue, 19 Feb 2013 18:33:01 +0000

The biodiversity of polar ecosystems in the Arctic and the Antarctic might be affected differently as temperatures raise. This is the main conclusion of a study published in the latest issue of the journal Marine Ecology Progress Series, conducted by scientists from The University of Western Australia’s Oceans Institute together with a team from the Spanish […]

Arctic’s Melting Permafrost and Snow Release CO2 in Massive Amounts

Leigh Hutchens — Sat, 16 Feb 2013 06:55:59 +0000

Scientists studying global warming have taken a particular interest in the freshet, or flooding triggered by melting snow each spring in the arctic. These waters contain much of the carbon that is being released by melting permafrost is then oxidized by bacteria into carbon dioxide. 40% of the total carbon that is transferred from the […]

Melt Ponds Accelerate Ice Melting More Than Previously Thought

Leigh Hutchens — Sat, 19 Jan 2013 06:21:34 +0000

This month, ice physicists at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have published their findings on light transmission through the Arctic sea ice in the scientific journal Geophysical Research Letters. Researchers found that more sunlight, and therefore energy, penetrates the areas where melt water collects on the ice that. […]
