Thats having effects that can be seen from the Arctic Circle to Africa, including melting permafrost, more pollen and fewer butterflies.

Below, five notable ways climate change can already be seen.

Whats happening: Permafrost, the layer of frozen topsoil commonly found in higher latitudes, is starting to thaw in some places. According to a United Nations report, observations at two permafrost monitoring networks indicate that largescale thawing may have a travelling bags for sale lready started.

Whats next: That could have more serious consequences, as the frozen soil has trapped decomposed organic matter. As it warms, it could release more greenh travelling bags for sale ouse gases, such as methane and carbon dioxide, speeding up climate change.

Whats happening: Polar bears depend on the sea ice to hunt and seek mates. But as the ice disappears, bear mortality rises. In 2008, polar bears were the first animals to be added to the Endangered Species Act list of threatened species because of global warming. Geological Survey has warned that twothirds of the worlds polar bear population could be lost within 50 years as the sea ice continues to retreat.

Whats happening: The latest research presented at the American College of Allergy, Asthma and Immunology in November showed that pollen counts are rising. Dr. Clifford Bassett, travelling bags for sale a New York allergist, explained that as the amount of carbon dioxide increases, some plants produce three to four times more pollen.

Whats next: Pollen counts in the year 2000 averaged 8,455, but by 2040 that number is expected to rise to 21,735 an increase of more than 250 percent.

Whats happening: Scientists in Mexico found that monarch butterfly numbers dropped 59 percent this year to the lowest levels since recordkeeping began 20 years ago. The decline could be due to increased wildfires caused in part by climate change, among other reasons.

Whats next: Further decline could affect tourism in the Mexican state of Michoacan, where Monarch butterflies are a major attraction. Experts say it could also hurt plants and other species connected to the butterfly.

Whats happening: There have been increased periods of drought, particularly in famineprone areas of Africa and Asia. The National Center for Atmospheric Research found that the percentage of Earths surface suffering drought has more than doubled since the 1970s.

Whats next: In Africa alone, the Intergovernmental Panel on Climate Change predicts that between 75 and 250 million people will be exposed to increased water stress due to climate change. travelling bags for sale
