Climate change is back in the news today after Obama's plan announcement, but it may not be enough. A new study shows that taking heat-trapping CO2 out of the atmosphere will slow global warming, but it won't stop it.

ABC Science reports that even the most aggressive timetables show little hope. To fix the problem, earth must stay below 2 degrees Celsius. We are currently on a 4 degrees Celsius trajectory.

Cutting carbon dioxide is still key to stopping the problem.

These studies were confirmed independently by different labs.

Though we have been aware of the problem for years, CO2 levels are still rising. The earth is still warming. Scientists are starting to doubt we can do anything to stop it.

Scientists led by Sabine Mathesius of the GEOMAR Helmholtz Centre for Ocean Research in Kiel, Germany used computer models to test different carbon-reduction scenarios, looking in each case at the impact on acidity, water temperatures and oxygen levels.

"We show that in a business-as-usual scenario, even massive deployment of CO2 removal schemes cannot reverse the substantial impacts on the marine environment -- at least not within many centuries," says Mathesius.

The oceans are becoming more acidic, which is a problem. Research shows that extracting massive amounts of CO2 won't be as helpful as originally thought. The report also announced that the world has lost several types of coral, which has disrupted the oceanic food chain.

"Immediate and ambitious action to reduce CO2 emissions is the most reliable strategy for avoiding dangerous climate change, ocean acidification, and large-scale threats to marine ecosystems," the researchers conclude.

In order to fix the problem, we will need to cut CO2 emissions by a third in the next few years.
