Jet stream changes cause climatically exceptional Greenland Ice Sheet melt
Research from the University of Sheffield has shown that unusual changes in atmospheric jet stream circulation caused the exceptional surface melt of the Greenland Ice Sheet (GrIS) in summer 2012. An international team led by Professor Edward Hanna from the University of Sheffield's Department of Geography used a computer model simulation (called SnowModel) and satellite data to confirm a record surface melting of the GrIS for at least the last 50 years - when on 11 July 2012, more than 90 percent of the ice-sheet surface melted.

Ancient trapped water explains Earth's first ice age
Ancient trapped water explains Earth’s first ice age
06 Jun 2013 Tiny bubbles of water found in quartz grains in Australia may hold the key to understanding what caused the Earth's first ice age, say scientists. The Anglo-French study analysed the amount of ancient atmospheric argon gas (Ar) isotopes dissolved in the bubbles and found levels were very different to those in the air we breathe today.

Major study compiles recent technology advances to more accurately predict climate-change impact
Major study compiles recent technology advances to more accurately predict climate-change impact on ice-sheet mass losses Climate change experts led by the University of Sheffield say advances in simulations are creating a more accurate picture of the future, and current global sea-level rise due to Antarctic ice loss might only be half what has been reported in major studies in the last few years.

City clocks tick faster: Urban blackbirds’ biological rhythms altered by setting
Biologists have discovered for the first time that the biological rhythms of city-dwelling organisms are changing in response to city living. Researchers measured the circadian rhythms of groups of urban and rural blackbirds in southern Germany and found that the city-dwellers had faster and less robust internal clocks than rural blackbirds.

Unexpected Effects of Ocean Acidification on Deep-sea Organisms
About 55.5 million years ago, geologically rapid emission of a large volume of greenhouse gases at the Paleocene-Eocene boundary (PETM) led to global warming of about 5oC, severe ocean acidification, and widespread extinction of microscopic organisms living on the deep-sea floor (foraminifera).

Unkempt, weedy land unintentionally boosts wildlife
Parts of the farm landscape that look overgrown and 'scruffy' are more important in supporting wildlife than they first appear, according to new research published today in Ecology Letters. The findings stem from an intensive study of an organic farm in Somerset by a team of scientists focussing on the complex ways in which animals and plants interact.

What plants will you eat in the Future? A showcase at RHS Chelsea Flower Show
PA 157/13 Food for the Future will be the focus of a fascinating exhibit created by scientists from The University of Nottingham at this year's RHS Chelsea Flower Show. The University's School of Biosciences is exhibiting for the first time at this year's centenary show, and the team are using the opportunity to showcase their latest research in the field of global food security The exhibit, which will be based in the Great Pavilion, will give visitors the opportunity to talk to leading Nottingham researchers and find out what they are doing to secure our food for the future.

Manufacturing areas are lighting up the City
Manufacturing areas in the city of Birmingham, which represent only a small percentage of the city's land area, are contributing significantly to urban lighting, according to research carried out by University of Birmingham environmental scientists published in the journal PLOS ONE today (Monday 6th May 2013).

Organic vapours affect clouds leading to previously unidentified climate cooling
06 May 2013 University of Manchester scientists, writing Geoscience, have shown that natural emissions and manmade pollutants can both have an unexpected cooling effect on the world's climate by making clouds brighter. Clouds are made of water droplets, condensed on to tiny particles suspended in the air.

Scientists use salt marshes to analyse global sea-level rise
The world’s salt marshes could hold the key to predicting future sea levels after scientists used them to pinpoint when recent rises began. Scientists analysed sediments and fossils buried in salt marshes which show the recent rise in global sea levels – posing a threat to millions of coastal homes worldwide – began around a century ago.

Behaviour of seabirds during migration revealed
Behaviour of seabirds during migration revealed
The behaviour of seabirds during migration - including patterns of foraging, rest and flight - has been revealed in new detail using novel computational analyses and tracking technologies. Using a new method called 'ethoinformatics', described as the application of computational methods in the investigation of animal behaviour, scientists have been able to analyse three years of migration data gathered from miniature tracking devices attached to the small seabird the Manx Shearwater ( Puffinus puffinus ).

Antarctica's transition to an ice world millions of years ago, revealed in study
Antarctica’s transition to an ice world millions of years ago, revealed in study
New study of sea floor core samples sheds light on how mammals and the Antarctic environment evolved in icy conditions. The emergence of mammals such as whales and penguins and the ecosystem that we are familiar with today in the seas off Antarctica can be traced back to when it was transformed into an icy world approximately 33.5 million years ago, according to research published today .

Revealed: Hunter gatherers’ taste for fish
A study involving scientists at the University of Liverpool has found the earliest use of ceramic pots was for cooking fish. In the first study to address the question of why humans made pots, scientists from the UK, the Netherlands, Sweden and Japan carried out chemical analysis of food residues in pottery up to 15,000 years old from the late glacial period.

A museum for the future
The University Museum of Zoology contains far more than a record of the past. Ambitious redevelopment plans will enable enhanced use of its unique collections for research into global issues from climate change to conservation. 1 million insects, 30,000 bird skins, 10,000 sets of eggs and over 3,500 fossil vertebrates: the Museum of Zoology is a treasure-trove of information about the natural world from 400 million years ago to the present day.

Ancient pool of warm water questions current climate models
Ancient pool of warm water questions current climate models
A huge pool of warm water that stretched out from Indonesia over to Africa and South America four million years ago suggests climate models might be too conservative in forecasting tropical changes.Present in the Pliocene era, this giant mass of water would have dramatically altered rainfall in the tropics, possibly even removing the monsoon.

Scientists take to air and sea to chart progress on greenhouse gases
Scientists will use the results from the project to help gauge and track progress on Government targets to curb greenhouse gas emissions by 80% by 2050. The project will measure gases emitted from various UK sources, such as industry, landfill and agriculture. Tracking their movements will also help researchers improve their current understanding of how the gases affect climate change.

Back to basics for climate models
Basic physics and statistic tools could offer a simpler and more meaningful way to model key elements of the Earth's climate, according to researchers at the University of Leeds and Brown University. The research, published in Physical Review Letters, shows that a technique called direct statistical simulation accurately models fluid jets, fast-moving flows that form naturally in oceans and in the atmosphere.
