Climate News Roundup: Week of 10/02
With Death of Forests, a Loss of Key Climate Protectors, NY Times, Oct. 1
Wildfires, extended drought, and uncontrolled beetle populations are some of the climate related threats facing American forests. In addition to being threatened by climate change, failing forests could themselves represent a two-fold threat to future climate: firstly, the forest could stop absorbing carbon, and secondly, they could release massive amounts of carbon back into the atmosphere if they were to burn or decay at a sufficiently high rate.
U.S. aviation lobbying ‘will not change European emission trading laws’, The Guardian, Oct. 4
Airlines from dozens of countries, led by the U.S., are increasing pressure to overturn an EU measure that would force airline carriers to pay for carbon emitted during takeoff and landing at European airports. While the airlines argue that the rule infringes on national sovereignty and aviation treaties, environmental groups and the EU remain firm that the rule is key to forcing the airline industry to play its part in combating climate change.
Climate change eradicating Arctic’s oldest ice, The Vancouver Sun, Oct. 5
NASA and the National Snow and Ice Data Center have issued a report documenting extensive shrinkage of ice cover in the Arctic for the 5th straight year. In addition, they have found that oldest Arctic ice is being replaced with younger, thinner ice sheets. This trend is of great concern, since with the disappearance of the oldest, thickest ice, the Arctic is more likely to experience ice-free summers in decades to come.
Is climate change affecting fall foliage?, USA Today, Oct.
Although no definitive study has been conducted in the U.S., several sources suggest that warming temperatures contribute to later leaf changing and dropping. Studies conducted in Europe and Japan have indicated that leaves are changing colors and dropping later, which suggests the same might be true in the U.S. Establishing a firm link between climate change and changes in fall foliage is difficult, since yearly fluctuations in precipitation, temperature extremes, and soil moisture play a large role in determining when and how trees will drop their leaves.
