Sea urchins cope with rising CO2 levels

(Phys.org) —Increasing levels of carbon dioxide (CO2) in the atmosphere are causing oceans to become more acidic. This situation poses a threat to marine organisms with shells made of calcium carbonate, because acid will ...

US scientists report big jump in heat-trapping CO2 (Update)

The amount of heat-trapping carbon dioxide in the air jumped dramatically in 2012, making it very unlikely that global warming can be limited to another 2 degrees (1.2 C) as many global leaders have hoped, new federal figures ...

Global warming less extreme than feared?

Policymakers are attempting to contain global warming at less than 2°C. New estimates from a Norwegian project on climate calculations indicate this target may be more attainable than many experts have feared.

Ups and downs of biodiversity after mass extinction

The climate after the largest mass extinction so far 252 million years ago was cool, later very warm and then cool again. Thanks to the cooler temperatures, the diversity of marine fauna ballooned, as paleontologists from ...

Scientists' role in swaying public opinion studied

(Phys.org)—Whatever their political persuasion, people are more likely to believe that global warming is caused by humans if they find out that most climate change scientists believe this is the case.

Fungi shifted plant balance of power

Cooperating with fungi didn't just help the earliest plants spread across a barren, rocky landscape; it also played a decisive role in the rise of more complex plants with roots and leaves that make up most of today's flora.

Study ups plant CO2 intake estimates

Plants may be able to limit the impact of our CO2 emissions even more than we previously thought, an innovative new experiment suggests.
