Equatorial water belt slackens

30 years of slowing Pacific circulation may have changed climate

A recent slowing in the circulation of Pacific Ocean waters could have raised Pacific sea surface temperatures. It may even mean that less carbon has reached the atmosphere from the ocean surface over the past two decades.

Across the Pacific, water circulates in two giant loops in the Northern and Southern Hemispheres. It flows from the subtropics to the tropics about at a depth of 100-400 metres, rises to the

Floodplains expert to train African environment managers

The delicate balance of life and death in Africa is nowhere more evident than on the banks of the continent`s mighty rivers. Rural communities depend on the rich silt brought down by rivers for farming but they are also at risk of devastating floods, as are urban dwellers in informal settlements that are often built on floodplains.

Dr Sue Marriott, reader in earth sciences at UWE`s Faculty of the Built Environment, is setting off this month to help with training environmental managers in fl

Atmosphere and Oceans Finely Balanced

The atmosphere and oceans exist in a delicate state of balance according to research co-ordinated by the University of East Anglia (UEA) and published this month by the Natural Environment Research Council (NERC).

The recently completed five year research programme of Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE) concludes that atmospheric pollution travels much further than previously thought and that this has important consequences for global chemistry and climate.

Life in a frozen environment – What´s in it for us?

Life on the moons of Jupiter, and a source of healthy polyunsaturated fatty acids and low temperature enzymes that could even make washing powders work at low temperatures: The microbes that live in Antarctic sea ice may hold the answers to a host of everyday applications as well as revealing how life forms might be able to exist on frozen planets. One of those interested in sea ice and the life forms it supports is Dr David Thomas of the University`s School of Ocean Sciences. He is presently the on

Soviet plans implemented by Nature 90,000 years ag

One of the more controversial environmental issues, which emerged in the final years of the Soviet era, was the plan to dam and reverse the flow of north-flowing rivers in order to irrigate the dry southern steppes. This scheme was roundly criticised by scientists and environmentalists at the time because of fears for the impact on the Arctic Ocean and global climate. It now appears that nature performed this experiment some 90,000 years ago.

Slick birds are wearing wool

Knitted pullovers protect penguins from oil discharge

Knitters around the world have pulled together to save thousands of oil-soaked little penguins on Phillip Island, southern Australia.

Ten thousand penguin-sized, pure-wool jumpers have flooded into the offices of the Tasmanian Conservation Trust in response to their call for emergency insulation for a vulnerable population of world’s smallest penguins – sometimes known as fairy penguins.

In mid-December 2001 a cru
