Over the last 40 years, Arctic sea ice thickness, extent and volume have declined dramatically. Now, a new study finds a link between declining sea ice coverage in parts of the Canadian Arctic and an increasing incidence of summer heat waves across the southern United States. Story here.

Downpours of torrential rain more frequent with global warming

The frequency of downpours of heavy rain—which can lead to flash floods, devastation, and outbreaks of waterborne disease—has increased across the globe in the past 50 years, research led by the University of Saskatchewan (USask) has found. Story here.

Climate change is already affecting global food production—unequally

The world's top 10 crops— barley, cassava, maize, oil palm, rapeseed, rice, sorghum, soybean, sugarcane and wheat—supply a combined 83 percent of all calories produced on cropland. Yields have long been projected to decrease in future climate conditions. Now, new research shows climate change has already affected production of these key energy sources—and some regions and countries are faring far worse than others. Story here.

Atmospheric researchers have developed a climate model that can accurately depict the frequently observed winding course of the jet stream, a major air current over the Northern Hemisphere. It demonstrates that the jet stream's wavelike course and subsequent extreme weather conditions like cold air outbreaks in Central Europe and North America are the direct results of climate change.
