Biophysical and economic limits to negative CO2 emissions

To have a >50% chance of limiting warming below 2 °C, most recent scenarios require large-scale deployment of negative emissions technologies (NETs). This study quantifies potential global impacts of the different NETs on various factors (such as land, greenhouse gas emissions, water, albedo, nutrients and energy) to determine the biophysical limits to, and economic costs of, their widespread application

Senators Revive Financing Tactic From ’70s for Carbon Emissions

19carbon-web-facebookJumbo
For years, power companies, manufacturers and entrepreneurs have tried to make capturing and storing carbon emissions from industrial operations like burning coal into a business, to little avail. Despite decades of promising research, demonstration projects and government investment, large-scale developments have often proved too difficult and costly to get off the ground.



Turning CO2 emissions into plastic with algae? It may not be as crazy as it sounds

algaeic plastic
From polyester shirts, plastic milk jugs and PVC pipes to the production of high-grade industrial ethanol, the contribution of the chemical feedstock ethylene can be found just about everywhere around the globe. But ethylene’s ubiquity masks an underlying environmental cost: The way it is produced emits more carbon dioxide than any other chemical process.

Unique pocket of roos reveals climate survival tactics

r1441523_20877844
Roo evolution The discovery of a genetically distinct group of eastern grey kangaroos sheds light on how they survived aeons of climate-induced expansion and contraction of their grassland habitat, say researchers. The population, unique to the Sunshine Coast in Queensland, formed as a result of a larger population becoming fragmented due to climate-induced changes in vegetation, they report in a recent issue of .

Bitterns, nightjars and cirl buntings are among several threatened bird species that could benefit from climate change and spread to more parts of Britain, a study has shown. Bees, wasps, earwigs and ants could also become more prevalent, according to the assessment of how 3,000 plants and animals would respond to rising temperatures.
