Another warm year as Bali conference ends

14.12.2007
The University of East Anglia and the Met Office’s Hadley Centre have today released preliminary global temperature figures for 2007, which show the top 11 warmest years all occurring in the last 13 years.

The provisional global figure for 2007 using data from January to November, currently places the year as the seventh warmest on records dating back to 1850.

The announcement comes as the Secretary-General of the World Meteorological Organization (WMO), Michel Jarraud, speaks at the Conference of the Parties (COP) in Bali.

Scientists and politicians have been in Indonesia discussing plans to reduce greenhouse gas emissions that have been linked to increasing global temperatures.

Dr Vicky Pope from the Met Office Hadley Centre has been attending the conference and said, “The last few days have provided an important platform for debate and confirms the need for swift action to combat further rises in global temperatures because of human behaviour.”

The last time annual mean global temperatures were below the 1961-1990 long term average was in 1985. Since then, mean surface air temperatures have continued to demonstrate a warming trend around the world. 2007 has been no exception to this, even though there has been a La Niña event which usually reduces global temperatures.

Professor Phil Jones, Director of UEA’s Climatic Research Unit, said: “The year began with a weak El Niño – the warmer relation of La Niña - and global temperatures well above the long-term average. However, since the end of April the La Niña event has taken some of the heat out of what could have been an even warmer year”.

In January the Met Office, in conjunction with the University of East Anglia, predicted that 2007 could record global temperature well above the long term average. There was also a 60% probability that 2007 could be the warmest on record and the expected temperature for 2007 is within the range predicted.

Professor Jones said: “2007 was warmer in the Northern Hemisphere, where the year ranks second warmest, than the Southern Hemisphere, where it ranks ninth warmest”.

Met Office Climate Scientist David Parker added: “This year has also seen sea-ice extent in the Northern Hemisphere below average in each month of 2007, with record minima sea-ice reported in July, August and September. In the Southern Hemisphere, sea-ice coverage has remained close to average”.

Meanwhile, across the UK, 2007 is on course to become one of the warmest years on record. Even if the mean temperature for December is 1 °C below the 1971-2000 long term average, the year will still be the 3rd warmest since UK-wide records began in 1914. In this 94-year series, the last six years (2002-2007) are set to become the six warmest years.

The full report on the climate of 2007 is available on the WMO website http://www.wmo.ch/pages/mediacentre/press_releases/index_en.html. As well as information and graphics on land and sea surface temperature, it includes details on the extent of sea-ice in both hemispheres and rainfall.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
