Sandwiched between the U.S states of Mayland, Delaware, Pennsylvania, New York State, the District of Columbia and Virginia, lies Chesapeake Bay, the largest estuary in North America. It is of huge ecological importance: “the bay, its rivers, wetlands and forests provide homes, food and protection for countless animals and plants”, says the Chesapeake Bay Program. Up to 150 major rivers and stream ...[Read More]

In the glistening waters of Indonesia, shallow corals – the rain forests of the sea – teem with life.  Or at least they did once. Towards the end of 2015 the corals started to die, leaving a bleak landscape behind. An international team of researchers investigated the causes of the die-off. Their findings, published recently in the EGU’s open access journal, Biogeosciences, are rather ...[Read More]

IPCC report ‘unprecedented changes’ in climate, urging policymakers to take action

October 4, 2013

“Human influence on the climate system is clear” was the key message from the report on the physical science of climate change from the Intergovernmental Panel on Climate Change (IPCC). “We have come a long way since the first IPCC report was published in 1990,” a statement reiterated throughout the press conference for the release of the report. The IPCC were keen to register the significance of ...[Read More]

Sussing out sea level rise

February 28, 2013

Ocean thermal expansion, that is, the increase in water volume due to temperature alone, is relatively well understood – as is the retreat of both mountain glaciers and ice caps. While most models simulate these effectively, there is little understanding of how both the Greenland and Antarctic ice sheets will respond to climate change. This is because the full extent of ice-ocean interactions is n ...[Read More]
