Climate Change is Fighting Back Against Wind Energy


Climate Change is predicted to have a massive impact on the world, from more fierce hurricanes to decreased snowfall. Additionally, the effects of climate change are predicted to complicate our ability to use windpower.  According to a recent study in the journal Nature Geoscience, could significantly weaken winds that blow across much of the world. Kristopher Karnauskas, a climate scientist at Colorado University Boulder and primary investigator, "Our results don’t show the wind power goes to zero. It’s a reduction of 10 percent over [most] regions."

To calculate their statistics, Karnauskas and his team used several different climate scenarios from the latest report from the Intergovernmental Panel on Climate Change (IPCC). They then combined them with a used formula in the industry to determine how much energy a turbine can produce. The study used 10 different IPCC models, each of which predicts with an large amount of CO2 going into the atmosphere. This data predicted that weather patterns would cause an eight to 10 percent decrease in the wind by 2050 and a 14 to 18 percent drop by 2100.

These changes may seem small to most people, but a minor drop in available wind can lead to massive amounts of energy lost. Geoff Spending, a professor of aerospace and mechanical energy at the University of Southern California believes that the overall energy generated from wind facilities would "drop significantly." That's because the energy generated from a wind farm is wind speed multiplied by three. So, Spending calculates that a 10 percent decrease would lead to a 30 percent decrease in wind energy generated. This new study is crucial because the United States Department of Energy is providing $20 million for research and development of offshore massive wind farms.

New Climate Study Increases Certainty of Warming Due to Greenhouse Emissions


In 2015, 197 countries from around the world gathered to ratify the Paris Climate agreement. By signing on to the agreement, 173 countries pledged to lower their greenhouse gas emissions in an effort to control global warming. At the time of the agreement, models had shown that Climate Change will lead to global temperature increases of 1.5 to 4.5 degrees Celsius (or 2.7 to 8.1 degrees Fahrenheit). (http://unfccc.int/paris_agreement/items/9485.php)

However, earlier this month, scientists at the University of Exeter in Great Britain published a paper that predicts the range of increase to be from 2.2 to 3.4 degrees Celsius (or 3.96 to 6.12 degrees Fahrenheit). Additionally, the paper reduces the uncertainty in previous models by 60%. In other words, the predictions are more accurate than previous predictions. (https://www.nature.com/articles/nature25450)


Those who say that 3 degrees Celsius is not a large increase are mistaken. if our warming reaches 3 degrees Celsius (5.4 degrees Fahrenheit), more than 100,000 square miles of wetlands and dry land will be lost. Furthermore, for each degree Celsius (1.8 F) of warming, there is a 400% increase in the area burned by forest fires in the United States alone.  (https://www.wired.com/story/the-dizzying-science-of-climate-change-gets-a-bit-clearer/)

Overall, the new climate models are important for climate optimism. Scientists are now less uncertain about how bad climate changes effects will be and can therefore make appropriate environmental preparations.

Cute, Cuddly, and Endangered : Giant Pandas have a Giant Problem

Cute, Cuddly, and Endangered: Giant Panda Have a Giant Problem         

In 1990, the International Union for Conservation of Nature (IUCN) officially declared the species known as the Giant Panda as endangeredIn 2014, scientists found that there were 1,864 giant pandas left alive in the wild. Though still very low, the population represented a real success, with the numbers increasing from around only 1,000 in the late 1970s. In the past decade, giant panda numbers have risen by 17 percent. This was also great news because, in 2016, it led to the Giant pandas being downgraded from endangered to vulnerable. For 28 years, scientists all around the world were trying to get the population to flourish, and they finally achieved the positive outcome they were looking for. Unfortunately, one year after this great success was announced, Chinese scientists had sobering news: The animal’s natural habitat,  temperate-zone bamboo forests in central China, was in serious danger.

Among the best recognized animals and now one of the rarest species, these black and white colored bears have come symbolize endangered species and conservation efforts across. For example, WWF (World Wildlife Fund), internationally known for its international conservation work, uses Chi-Chi the Panda as an inspiration for its logo. 


According to the National Zoo, giant pandas are found in the wild only in the remote, mountainous regions of central China, in Sichuan, Shaanxi and Gansu provinces.  The cool, wet bamboo forests in these are perfect for the giant panda's needs. 
Unfortunately, the giant panda’s habitat--which once spread across central, southern, and eastern China, and into China’s neighboring countries of Myanmar and northern Vietnam--has been dramatically reduced by the growth in logging and farming.
Now, the species is restricted to only about 20 isolated patches in western China’s Sichuan, Gansu, and Shaanxi Provinces (cite).

          Currently, the most pressing issues for the Giant Panda are loss and fragmentation of habitat. Fragmentation occurs when a species' habitat  is divided into several small isolated patches. A large proportion of the panda's habitat has already been lost (mostly due to logging for timber and fuel wood) or cleared for farming or buildings to support the teeming population in China. Though the Chinese government banned logging in the panda's habitat in 1998, new roads and railways continue to cut through the region, further fragmenting the home of the pandas. This isolates panda populations and prevents them from breeding successfully, which leads to a decrease in population. Other threats to the numbers of Giant Pandas include harvesting, hunting, and tourism. Seventy-five percent of the plants in Giant Panda habitat is used for traditional Chinese medicine. Harvesting these plants contributes to habitat loss. Increasing tourism around the world is a problem as well. The construction of tourist facilities and the rapidly increasing number of tourists in the forests and China is disturbing pandas and their habitats. Lastly, poaching, though not a really large issue for pandas, does happens accidentally in China even under the strict laws and great public awareness. Hunters kill pandas for their fur, meat, and other parts of the panda's body. Although it is rare for someone to kill a panda intentionally, Pandas still get caught in traps intended for other animals such as musk deer and black bears, which can severely injure or kill them.

What can you do?
You can help the conservation effort by donating to WWF or World Wildlife fund Funding, travelling smart, and spreading the word. Tell your family, friends, whoever and they can help contribute too!
