Results from a new climate reconstruction of how Antarctica’s ice sheets responded during the last period when atmospheric carbon dioxide (CO2) reached levels like those expected to occur in about 30 years, plus sediment core findings reported in a companion paper, suggest that the ice sheets are more vulnerable to rising atmospheric CO2 than previously thought. Details appear in two […]

Annual global carbon dioxide emissions from fossil fuels could drop slightly in 2015, according to a report from the Global Carbon Project led by a Stanford University researcher. This surprising result contrasts with the rapid growth in emissions before 2014, underlining the need for action to stabilize and permanently lower global CO2 emissions, the researchers conclude. “In 2014, global CO2 […]

Crested and rockhopper penguins are threatened by climate change – but this time the penguins could be at risk because they cannot change their own ways. Evolution has left them with a rigid parenting strategy, probably well adapted for climate conditions so far. But as temperatures rise, conditions change and food supplies become precarious, the inflexible roles of male and female […]

An influential panel of climate scientists has expressed higher confidence than ever that human activity is the main cause of the rise in global temperatures since the 1950s, Reuters.com reports. A leaked draft of an upcoming report of the United Nations’ Intergovernmental Panel on Climate Change, based on a broad analysis of published scientific studies, concludes with 95 percent certainty […]

What happened A United Nations panel of the world’s leading environmental scientists issued its most dire warnings on the dangers posed by climate change, saying global warming is already affecting every continent and threatens to devastate food supplies, cause mass extinctions of plants and animals, worsen droughts, and raise the risk of wars over resources. The longer society holds off […]

Climate change, not just increasing atmospheric temperatures, has been affecting the Jet Stream. When the Jet Stream travels across from the West to the East over the Northern Hemisphere in normal conditions the weather is not greatly affected, but because of the climate change it has been slowing down and causing massive heat waves and flooding. When the jet stream […]

Tropical groundwater may prove to be a climate-resilient source of freshwater in the tropics as intense rainfall favours the replenishment of these resources, according to a new study published in Environmental Research Letters. As climate observations show that global warming leads to fewer but more intense rainfalls, a clearer understanding of how these sources are replenished is crucial for developing […]

In a study published in the journal Nature Climate Change, scientists from three universities show that products made in China are associated with significantly higher carbon dioxide emissions than the same products made elsewhere. “The amazing increase in Chinese manufacturing over the past 15 years has driven the world economy to new heights and supplied consumers in developed countries with […]

The Pine Island Glacier has been melting due to a volcano heat source that researchers have found underneath the glacier in Antarctica. The volcanic activity was first noticed in 2007 and then verified in 2014. This volcanic activity was discovered by some scientists at the University of Rhode Island’s Graduate School of Oceanography. From January to March of 2014 scientists […]

New South Wales and southern Queensland are going to be suffering from warmer weather and less rain than in the past. This temperature change is called “sudden stratospheric warming.” It happens when the air above the South Pole starts to warm up rapidly. Predictions are that the warming of Antarctic will likely be higher than a previous record high in […]
