Carbon Emissions Continue to Rise Despite Reductions

In a report entitled “Long-term trend in global CO2 emissions” prepared by the European Commission’s Joint Research Centre and PBL Netherlands Environmental Assessment Agency, it has been found that global emission of carbon dioxide (CO2) have increased by 45% between 1990 and 2010 and reached an all-time high of 33 billion tonnes by 2010, all despite increased energy efficiency, nuclear energy and a growing renewable energy industry.

Unprecedented Portrait of Global Greenhouse Gases in Atmosphere

HIPPO – HIAPER Pole-to-Pole Observations – is the name of an unprecedented three-year series of research flights from the Arctic to Antarctica which has provided scientists with a first of its kind portrait of greenhouse gases and particles in the atmosphere.

No Tipping Points for Arctic Sea Ice Loss

A growing body of scientific evidence has led researchers to believe that in a warmer climate there will be no “tipping point” beyond which the Arctic sea ice cannot recover if temperatures start to decrease. Added to this is new research out of the University of Washington which suggests that even if the planet warmed enough to melt all polar sea ice, it could still recover if the temperatures cooled again.

What Will a 4 Degree Increase do to Australia

The results of research looking into what will happen to the Australian climate if and when a global increase of 4º Celsius across the world takes place was presented by CSIRO’s Dr Penny Whetton at the Four Degrees climate change conference in Melbourne.
