Litter is present throughout the world's oceans: 1,220 species affected
March 27, 2017 01:06 PM - Alfred Wegener Institute - Helmholtz Centre For Polar and Marine Research

Where is marine litter concentrated, and which species and ecosystems does it affect? Researchers at the Alfred Wegener Institute have for the first time compiled all scientific data published on marine litter in a single, comprehensive database, now accessible from the online portal AWI Litterbase (www.litterbase.org). Here, both the distribution of litter and its interactions with organisms are presented in global maps. In addition, the regularly updated datasets are fed into graphic analyses, which show e.g. that seabirds and fish are particularly affected by litter. The latest interaction analysis shows that 34 per cent of the species monitored ingest litter, 31 per cent colonise it, and 30 per cent get entangled or otherwise trapped in it (for all figures: valid as of 23 March 2017). The total number of affected species is rising steadily and is currently at 1,220 – more than twice the number reported in the last review article. These numbers will change as the database is being updated regularly.

Another Study Points to Climate Change's Direct Role in Fueling Extreme Weather

Climate change is impacting major air currents that control extreme weather events, helping to power natural disasters like heat waves, droughts, wildfires, and floods in North America, Europe, and Asia, according to a new study published in the journal Scientific Reports.

Fish evolve by playing it safe

New research supports the creation of more marine reserves in the world’s oceans because, the authors say, fish can evolve to be more cautious and stay away from fishing nets.

Carnegie Mellon University Launches Carbon Emissions Index
March 21, 2017 03:06 PM - College of Engineering - Carnegie Mellon University

Mitsubishi Hitachi Power Systems (MHPS) and Carnegie Mellon University (CMU) today announced the creation of a new index that will measure carbon dioxide emissions from the U.S. electrical power generation sector. The Carnegie Mellon Power Sector Carbon Index will track the environmental performance of U.S. power producers and compare current emissions to historical data collected nationwide for more than two decades. A quarterly press release will inform interested parties of power sector carbon emissions performance trends.  In addition, CMU will provide an online resource for a wide variety of power sector emissions data and forecasts.

Boulder scientist teams on study probing implications of ice sheet's demise
March 21, 2017 01:25 PM - Charlie Brennan via University of Colorado at Boulder

Flying over the remote during research at the Barnes Ice Cap on Baffin Island in 2009, a Boulder scientist saw dark where there should have been white.

Closer inspection revealed that what Gifford Miller spotted was the remnants of a 1963 geological camp that had been buried for decades by snow and ice. Long-abandoned tents and snowmobiles were being unveiled by melting of the ice cap, and that helped inspire a study that suggests a disturbing climate change signal.

CO2 Levels Continue to Increase at Record Rate
March 14, 2017 02:02 PM - Yale Environment 360

For the second year in a row, carbon dioxide levels in the atmosphere have increased at a record rate, jumping 3 parts per million (ppm) in 2016, according to data from the National Oceanic and Atmospheric Administration. CO2 concentrations rose 3.03 ppm in 2015, making the last two years the first time that the greenhouse gas has risen more than 3 ppm in NOAA’s 59 years of monitoring, Climate Central reported.

The UK's Drop in CO2 Emissions Shows the Power of Carbon Taxes

A new analysis indicates that the UK’s CO2 output is at a record low, and it’s largely down to one major action: a reduction in coal use.
