First signs of healing in the Antarctic ozone layer
New research has identified clear signs that the hole in the Antarctic ozone layer is beginning to close. Scientists from NCAS and the University of Leeds were part of an international team led by Professor Susan Solomon of the Massachusetts Institute of Technology to confirm the first signs of healing of the ozone layer, which shields life on Earth from the sun’s harmful ultraviolet rays.
Recovery of the hole has varied from year to year, due in part to the effects of volcanic eruptions. But accounting for the effects of these eruptions allowed the team to show that the ozone hole is healing. These encouraging new findings, published today in the journal Science, show that the average size of the ozone hole each September has shrunk by more than 1.7 million square miles since 2000 – about 18 times the area of the United Kingdom.
Into The Blue - Science we live and breathe
25th - 29th October 2016
Following on from the success of the activities and public engagement events for NERC’s 50th anniversary, including the main event where the RRS Discovery went to London in 2015, NCAS has been asked, by NERC to be central to activities in 2016. We’ve been asked to showcase the UK’s largest research aircraft, and alongside this to run an event in the autumn of 2016.
The event, known as into the blue, will centre on the FAAM aircraft and a wide range of NCAS and NERC science at a five day event in Manchester. We’ll be taking the aircraft to Manchester airport, and there will be a large exhibition space at the Runway Visitors Centre.
A Spiral of Global Temperatures
Over the past week, an animated plot made by NCAS Scientist Dr Ed Hawkins has been causing quite a stir on Twitter, as of May 5th at 10am, it had been retweeted or shared over 8500 times, and has been the subject of many news stories (Such as this one in The Washington Post) and blog articles all over the internet. Originally published on Ed's blog the Climate Lab Book, and then shared via Twitter the plot is a simple visualisation of the monthly global temperature from 1850 through to 2016.
“It was just designed to try and communicate in a different way. As scientists I think we need to communicate, and try different things, and this was just one of those trials, and it has turned out very well,” Hawkins says. (He credits Jan Fuglestvedt, a fellow researcher at the University of Oslo, with suggesting the idea of a spiral to him).
To make the plot Ed used HadCRUT4.4 from January 1850 – March 2016, relative to the mean of 1850-1900. “The animated spiral presents global temperature change in a visually appealing and straightforward way,” Hawkins wrote on his blog, the Climate Lab Book. “The pace of change is immediately obvious, especially over the past few decades.”
