Climate Change

Do 97% of Climate Scientists Agree about Climate Change? (Hint: It’s Many More)

Written by , on January 24, 2016

Almost everyone seems to accept the often quoted claim that 97% of climate scientists agree that climate change is real and man-made – but is the figure accurate?  Read more »

Lake Chad – Linking Climate, Water and Terrorism

Written by , on February 23, 2015

The changes in the lake have contributed to local lack of water, crop failures, livestock deaths, collapsed fisheries, soil salinity and increasing poverty throughout the region. All of this has turned the region into a hotbed of tribal violence and terrorism.  Read more »

Insurance Industry Report Finds Increasiing Weather Catastrophes

Written by , on September 27, 2013

The leading international insurance and risk management think tank, has released a report showing that “ocean warming has effectively caused a shift towards a ‘new normal” for a number of insurance-relevant hazards’.  Read more »

Vegetation Advancing North

Written by , on March 22, 2013

As the warming climate causes ice and snow to retreat, vegetation is increasing towards the Arctic. A new analysis of satellite data, collected since 1982, has revealed a vigorous increase in vegetation growth between the 45th parallel north and the Arctic Ocean. In many places, the climate has shifted north by as much as 4 […]  Read more »

Which Came First: The CO2 or the Warming?

Written by , on March 4, 2013

Data collected from Antarctic and Greenland ice cores seems to show CO2 levels rising centuries after temperature increases. However, new research suggests that this may be a misinterpretation of the evidence. Scientists have been using bubbles of air trapped in the ice when it was formed to detemine the CO2 level in the air at […]  Read more »

Removing Top Predators Can Dramatically Change CO2 Emissions

Written by , on February 18, 2013

When Trisha Atwood of the University of British Columbia studied the effect of removing predator fish from ponds and rivers in Canada and Costa Rica, she found a consistent pattern – carbon dioxide emissions increased more than tenfold after the predators were removed. Wiping out the top predator results in a "trophic cascade" in which […]  Read more »

Research Shows Ocean Iron Ferilization Costly and Ineffective

Written by , on December 14, 2012

Daniel Harrison, a postgraduate research engineer at the University of Sydney, has published results of research demonstrating that fertilisation of the ocean with iron does not store carbon long enough to be an attractive contributor to climate management. Ocean iron fertilisation is a process that attempts to encourage phytoplankton growth in regions with unused nutrients […]  Read more »

Simulating Climate Change in Woodlands

Written by , on May 15, 2012

Scientists at the University of Western Sydney have embarked on a large-scale study of how the natural environment would cope with the atmospheric conditions which are expected if if no significant action is taken to reduce carbon emissions. The centrepiece of the study is six fibreglass and steel ring structures 28 metres high and 25 […]  Read more »

More Accurate Measures of Melting Icecaps

Written by , on February 15, 2012

U.S. scientists using satellite data have established a more accurate figure of the amount of annual sea level rise from melting glaciers and ice caps. There are more than 160,000 glaciers and ice caps worldwide but annual changes in mass have been directly measured for only 120 of them and, in most cases, only within […]  Read more »
