Watch 25 Years of Arctic Sea Ice Disappear in 1 Minute
 
01:05
VIDEO CREDIT: NOAA Since the 1980s, the amount of perennial ice in the Arctic has declined. This animation tracks the relative amount of ice of different ages from 1987 through early November 2015. The oldest ice is white; the youngest (seasonal) ice is dark blue. Key patterns are the export of ice from the Arctic through Fram Strait and the melting of old ice as it passes through the warm waters of the Beaufort Sea. In 1985, 20% of the Arctic ice pack was very old ice, but in March 2015, old ice only constituted 3% of the ice pack. Animation by NOAA Climate.gov team, based on research data provided by Mark Tschudi, CCAR, University of Colorado. Sea ice age is estimated by tracking of ice parcels using satellite imagery and drifting ocean buoys. References: Charctic Interactive Sea Ice Graph. National Snow and Ice Data Center.

Drilling Back to the Future: Climate Clues from Ancient Ice on Greenland
 
06:15
In July of 2009, Climate Central senior research scientist Heidi Cullen traveled to Greenland with a production team from StormCenter Communications to visit the North Greenland Eemian Ice Drilling Project, or NEEM. Scientists from 14 nations gather together each summer in northern Greenland, where they work to drill a core of solid ice, looking into the past for clues to future climate change. The NEEM scientists are focused on a period known as the Eemian, which began about 130,000 years ago and lasted about 10,000 years. During the Eemian, temperatures were between 5 and 9 degrees F warmer than today, and global sea level was 13 to 20 feet higher. Under many climate change scenarios, global temperatures are projected to warm a similar amount this century, so understanding the climate of the Eemian could teach us more about the potential effects of warming today. To study past climate, the scientists rely, in part, on information trapped inside tiny bubbles in the ice. These bubbles contain traces of the ancient atmosphere. In an underground trench carved from the snow, the scientists work in a makeshift laboratory to extract information from the ice. To do so, they use an analytical system called "continuous flow analysis", where they take a section of the ice core, and melt it on a hot plate millimeter by millimeter. As the bubbles pop, the data is retrieved. Other ice core samples are cut, bagged, and shipped to research centers all over the world directly from the NEEM camp. This creates a difficult logistical effort that is made possible by the 109th Airlift Wing of the New York Air Force National Guard. Pilots from the 109th fly specialized planes, called LC-130s, essentially a C-130 aircraft equipped with skis. The ice cores provide the NEEM scientists with priceless information about past climate history. The data from the cores show a strong correlation between carbon dioxide levels and temperature, reinforcing an important theme from climate science: that carbon dioxide causes warming. Learning about these ancient climates can also tell us more about future sea level rise. The Greenland ice sheet contains enough ice to raise global sea level by 23 feet. By using Satellite data from the NASA Grace Mission, scientists have been able to measure Greenland's current ice loss. In 2007, Greenland shed 340 billion tons of ice — a loss roughly the same as draining an extra San Francisco Bay's worth of water into the ocean every week for a year. By the end of the 2010 season, when the scientists drill down to the Eemian period, they will get a much better sense of just how much Greenland's ice melted during the last major warm period, when global sea level rose 13 to 20 feet higher than it is today. For more about NEEM and the stories of the people who make it possible, watch Ice Cores and Climate, The Pilots of the 109th Airlift Wing, or Life on the Greenland Ice Sheet, three short videos originally broadcast on The Weather Channel.

Carbon Debt
 
02:47
Several studies have suggested that corn ethanol makes a modest improvement over gasoline in terms of greenhouse gas emissions. However, none took the concept of carbon debt into account. Carbon is stored in the soil through the process of photosynthesis. Plants and grasses take in carbon dioxide from the air, and store it in their shoots, leaves, and roots as organic carbon. When these plants decompose, they leave some of their carbon in the soil. When land is cleared and soil is tilled to plant corn, or any other crop, the carbon from soil and the vegetation cleared is released into the atmosphere. This release of carbon dioxide is called carbon debt, and when you take into account this debt along with the production process to create corn ethanol, ethanol can become worse than gasoline in terms of greenhouse gas emissions. Therefore, even though ethanol may help reduce reliance on foreign oil, once you take into account the consequences of any related changes in land use, total greenhouse gas emissions may actually exceed those from gasoline.

Ben Strauss on Antarctic Ice Melt with PBS NewsHour
 
04:40
Our CEO and chief scientist Ben Strauss went on air with Hari Sreenivasen of PBS NewsHour to talk through a new study on Antarctic ice melt and what that may mean for coastal cities in the U.S. — particularily on the East Coast. "South Florida is severely at risk particularly because their bedrock is porous. So even if you built levees or protected walls, water would push underneath them come up through the ground. So there are really high stakes here." Antarctica, a continent of snow and ice, is now losing ice three times faster than it was in 2007. In a new study published last week in the journal Nature, more than 80 scientists from multiple countries use satellite data to examine the Antarctic’s vast ice sheets, and their prediction is that if the current rate of ice melt continues, sea levels could rise six inches by the year 2100.

Polar motion describes the motion of the Earth's spin axis (shown in orange) with respect to the geographic north and south poles (shown in blue). Over time, the geographic poles appear to spin away from the spin axis when viewed from space and then back again. Viewed from the perspective of someone on Earth, the spin axis instead appears to spiral away from the geographic poles and then spiral back. The motion of the spin pole with respect to the geographic poles fixed to the Earth's crust is called polar motion.

Taking the Carbon Out of Coal
 
02:08
A company called SCS thinks it can use coal to generate electricity while cutting down 90% on carbon emissions — and still make a profit. The company's PurGen plant, which would be located on the site where an old Dow Chemical plant used to stand near the New Jersey Turnpike in Linden, NJ, would use a technology called carbon capture and storage, or CCS. Carbon dioxide coming from the coal would be captured and pumped in liquid form deep underground, where it would — presumably — stay. To continue using coal while achieving an 83% reduction in greenhouse gas emissions by 2050, as called for in proposed legislation being discussed in Congress, will require increasing amounts of CCS in the coming decades. The PurGen plant would not burn coal, but rather turn it into hydrogen through a process that generates a stream of pure CO2 as a by-product. The hydrogen would be burned to make electricity with very little air pollution — but only when the demand for electricity is high, and the plant can get a good price. At times when demand is low, the hydrogen would be diverted and converted on-site into the chemical urea, used to make fertilizer. The storage part of SCS's plan involves building a two-foot-diameter pipeline to carry liquefied CO2 from the plant, under the Arthur Kill — a waterway separating New Jersey from Staten Island — and 140 miles out to a point on the bottom of the Atlantic Ocean, where it would be injected and stored about 8,000 ft. beneath the sea floor in a suitable geological formation. Supporters say the plan is a perfect solution to several problems at once — how to use the nation's cheap, plentiful coal supply without adding heat-trapping CO2 to the air, how to provide clean electricity to a part of the country that has to import power, and how to spark a green energy industry that could help the US maintain economic leadership in a time when China and other nations are determined to wrest it away. But not everyone thinks the PurGen project is a good idea. For one thing, even if the plant makes electricity cleanly, the mining and transport of coal will still have environmental impacts. For another, some worry that sequestering CO2 underground hasn't been adequately tested yet. And other critics say the money for PurGen would be better spent on solar or wind energy or energy efficiency — challenging the very premise that finding a way to use coal without carbon emissions is needed.

How Much Will Sea Level Rise?
 
02:44
There are two main reasons why sea level is rising as the world gets warmer. First, as ice sheets and glaciers melt, they send ice and water pouring into the oceans. But another reason is that water, like most substances, expands as it heats up — and as greenhouse gases warm the atmosphere, some of that heat is slowly warming the oceans as well. Scientists understand the expansion of water really well; you can look it up in a textbook. It is much harder to predict what will happen to the ice, though. It is not just the melting ice that scientists have to contend with — it is also the fact that tidewater glaciers (glaciers that flow into the sea) and ice sheets move downhill faster with warming. In places like Greenland, that means they drop chunks of ice into the sea at a greater rate than they have in the past — and adding ice to the sea faster than it can melt drives sea level higher. (By contrast, the melting of ice that was in the sea all along, like the ice pack that covers the Arctic Ocean in winter, does not make sea level rise at all. If you have a glass of water with ice cubes in it filled nearly to the top, it does not overflow as the ice melts. But dump more ice into that glass and see what happens). In part because of that uncertainty, and also because of insufficient information about the relationship between melting and sea level in the past, the authoritative Intergovernmental Panel on Climate Change, or IPCC, counted only the expansion of seawater and the increased melting in its latest report. It left the motions of glaciers out entirely. The IPCC knew this could be important, but did not have enough information to estimate it. Thus, everyone knew that the IPCC's projection that sea level would rise between half a foot and two feet by the end of this century was not the whole story. Since that report came out in early 2007, though, scientists have gotten a better handle on the uncertainties. They now project that three or four feet of sea-level rise is likely by century's end, if emissions of greenhouse gases continue to grow at current rates. For millions of people who live in low-lying coastal areas, that's a direct threat. It is a threat to many millions more because surges of water from storms will push seas even further inland. Coastal marshes tend to absorb the energy of waves and surges. If they disappear under the rising sea, that buffer will be gone, making the land more vulnerable to flooding and erosion. And rising saltwater could get into underground supplies of fresh water. That could threaten drinking-water supplies, disrupt coastal agriculture, and destroy ecosystems. Finally, when heavy rains on land send water gushing down rivers, the rivers will start backing up and flooding low-lying land sooner. A sea-level rise of three feet might not sound like a lot, but it could do enormous damage.

Wind Energy
 
01:43
You can't see it or hold it, but scientists estimate that wind has the potential to supply the world's electricity five times over while producing almost no greenhouse gas emissions. Yet the US currently gets less than two percent of our electricity from wind power. Wind energy's share is set to increase with the approval of the Cape Wind project off the Massachusetts coastline, and the other offshore projects that may follow in its wake. Large commercial wind farms are a relatively new idea. The wind turbine is a young technology with high costs, but those costs are falling as more turbines are built. In the US, the majority of wind farms located in the "wind belt" that stretches from Texas to Montana and North Dakota. But the location of the wind belt brings another challenge. It is located far from either coast. To harness and utilize wind energy, new transmission lines would have to be built to connect the wind belt to the more populated areas on the East and West coasts. And wind doesn't blow all the time, which means either a back-up source of energy will be needed -- or a way to store wind power. So while the costs of wind turbines are dropping, the problems of wind intermittency, remote locations, and an insufficient energy grid will need to be resolved before this clean and renewable energy source can become truly competitive.
