Climate scientists need to pay more attention to what indigenous peoples have to say on climate change, said Betsy Weatherhead, an atmospheric physicist at the University of Colorado.
At the American Association for the Advancement of Science annual meeting in Vancouver on Saturday, Weatherhead said indigenous peoples in the Arctic have been documenting changes in not only temperature, but also weather patterns and changes in the ice around them for generations.
When it comes to protecting the biodiversity of our oceans, Canada has fallen behind most other developed countries according to the final report by an expert panel convened by the Royal Society of Canada.
The report, released Feb. 2, examines the effects of fisheries, fish farming, and climate change on Canada’s oceans, and assesses the Government’s response to these threats.
Speaking at an online press conference, Jeffrey Hutchings, the chair of the expert panel and the Canada research ...

In the not-so-distant future, mountaintops across the world may look a lot more like mountain bases.According to a study published in the journal Nature Climate Change last week, alpine plant communities may be changing more quickly than expected as a result of warming temperatures. Researchers from across Europe catalogued 867 different plant species from 60 peaks across the continent, first in 2001 and again in 2008. They discovered that plants generally found in warmer areas of a mountain are ...
Rapid glacial retreat happening all over the world is known to have been brought on by climate change, but the melting patterns of many glaciers have now been linked to the circulation of ocean water.
A recent study by the Woods Hole Oceanographic Institution (WHOI) reveals that heat transported through Greenland’s ice sheet has caused glaciers there to lose mass, increasing flow speeds. Melting occurs as a result of warm water reaching the fjords, circulating and interacting with the glacier ...

After reading this you may want to buy stock in - or stock up on - Kleenex. Ragweed pollen is lingering in the air for more than a month than it did in 1995, says a study published last month in the Proceedings of the National Academy of Sciences.
The increase is accredited to rising temperatures and delayed fall frosts in northern regions. According to the U.S. Department of Agriculture (USDA), this means that the allergy season will also end much later in the year.
