New study documents the natural relationship between CO2 concentrations and sea level

Jan 2, 2013 | Posted by: roboblogger | Full story: EurekAlert!

By comparing reconstructions of atmospheric CO2 concentrations and sea level over the past 40 million years, researchers based at the National Oceanography Centre, Southampton have found that greenhouse gas concentrations similar to the present were systematically associated with sea levels at least nine metres above current levels.

May I suggest as many do anyway ignore the scientific science fiction clap trapper commander AKA spacedoutblues.Well if you do that our free entertainment will go away and real science will be posted.

RIP. Seymour Laxon's work led to the first detailed map of the Arctic gravity field.

My friend Seymour Laxon, who has died aged 49 after sustaining a head injury during a fall, was an internationally respected Earth scientist. Seymour used satellites to observe the polar ice caps and the focus of his research was sea ice, a key factor in understanding the global climate since it acts as a barrier to heat and moisture exchange between the ocean and the atmosphere.

Seymour was the only child of Veronica, a psychology lecturer, and Bill, a civil engineer and pioneer of computer-aided design. Inheriting his father's interest in computers, as a teenager Seymour was one of the generation who cut their teeth programming the first home computers in the early 1980s.

He studied physics and astronomy at University College London, where his neat and structured lecture notes showed a clear and well-organised mind at work. It was no surprise when he went on to undertake a PhD at UCL's Mullard Space Science Laboratory in Surrey. There, he met his partner of 19 years Fiona Strawbridge.

Seymour's scientific breakthrough was to distinguish the ice surface from the water surface in satellite radar altimeter measurements of ice-covered oceans. This led to the first detailed map of the Arctic gravity field, revealing new tectonic features beneath the seafloor, and water circulation beneath the ice. His work helped give the European Space Agency the confidence to build CryoSat, a satellite dedicated to observing the Earth's ice-covered regions, launched in 2010.

Seymour taught at UCL's department of space and climate physics, before moving to the department of Earth sciences, where he was director of the Centre for Polar Observation and Modelling. He was awarded his chair in climate physics in 2012.

A cyclist killed in a crash in central London was a talented scientist doing research on global warming, her employer has said.

Dr Katharine Giles, a lecturer at University College London (UCL), was on her way to work when she collided with a tipper truck in Victoria on Monday.

She had travelled to the Arctic and the Antarctic to study the sea ice.

Dr Giles had a "bright future" and was "ready to provide the next generation of leadership" in the field, UCL said.

Dr Giles had taken on new commitments at the Centre for Polar Observation and Modelling at UCL following the accidental death of her colleague Seymour Laxon earlier this year.

A statement from the head of the earth sciences department, Prof Phil Meredith, said: "Coming so soon after the accidental death of Katharine's own closest colleague, Seymour Laxon, we are all left with a sense of the outrageous unfairness with which some of our best colleagues have been taken from us.
