LSU researchers have discovered a new relationship between climate change, monarch butterflies and milkweed plants. It turns out that warming temperatures don’t just affect the monarch, Danaus plexippus, directly, but also affect this butterfly by potentially turning its favorite plant food into a poison.

Mitsubishi Hitachi Power Systems (MHPS) and Carnegie Mellon University (CMU) today announced the release of the 2018 Carnegie Mellon Power Sector Carbon Index, at CMU Energy Week, hosted by the Wilton E. Scott Institute for Energy Innovation. The Index tracks the environmental performance of US power producers and compares current emissions to more than two decades of historical data collected nationwide. This release marks the one-year anniversary of the Index, developed as a new metric to track power sector carbon emissions performance trends. 

Speeding up progress on reducing carbon emissions would save millions of lives, mostly in metropolitan areas of Africa and Asia.

A research project conceived by a Brandon University (BU) professor on the northward spread of palms has been featured in the prestigious science journal Scientific Reports and on Columbia University’s Lamont Earth Institute State of the Planet blog.

When NASA's Aqua satellite passed over Tropical Cyclone Iris near the coast of Queensland, Australia it measured cloud top temperatures and found strong storms with the potential for creating heavy rainfall.

Tropical cyclone Josie didn't make landfall in Fiji but its heavy rainfall resulted in deadly flooding. NASA calculated the rainfall that Josie left in its wake as it moved south of Fiji and began weakening.

Remote areas in Canada’s Arctic region – once thought to be beyond the reach of human impact – are responding rapidly to warming global temperatures, the University of Toronto's Igor Lehnherr has found.

The Sahara Desert has expanded by about 10 percent since 1920, according to a new study by University of Maryland scientists. The research is the first to assess century-scale changes to the boundaries of the world’s largest desert and suggests that other deserts could be expanding as well. The study was published online March 29, 2018, in the Journal of Climate.

Walleye, an iconic native fish species in Wisconsin, the upper Midwest and Canada, are in decline in northern Wisconsin lakes, according to a study published this week in the Canadian Journal of Fisheries and Aquatic Species.

As soon as they start life, it's all about survival for juvenile young fish. They must learn to catch prey and to escape enemies. Additionally, at this stage of their lives they are highly sensitive to environmental factors such as temperature, oxygen and the pH of the water. Exactly these factors are currently changing on a global scale: temperature is rising, the oxygen content of the ocean is decreasing and more and more carbon dioxide (CO2) from the atmosphere dissolves in the seawater, where it forms carbonic acid and lowers the pH level. But not only directly, also indirectly elevated CO2 affects the survival of fish larvae, because it can change their food supply.
