greenhouse gases contribute to global warming
Professor Euan Nisbet, from the Department of Earth Sciences at Royal Holloway, University of London is a key figure in this week’s two-day conference on greenhouse gases in the atmosphere.
The conference, which is taking place at the Royal Society in London, will discuss the use of long-term monitoring to understand greenhouse gases in the Earth System.
Professor Nisbet, leader of the Greenhouse Gas Activity in the European Union’s GEOman Global Monitoring project, is one of the organisers and chair of the event. He is joined by leading academics from across the world to bring climate change to the fore once again.
In his joint presentation with Dr Ed Dlugokencky of the Earth System Research Laboratory in Boulder Colorado, on ‘Global atmospheric methane in 2010: budget, changes and dangers,’ he reveals atmospheric levels of the greenhouse gas, which is more potent than carbon dioxide, has risen significantly for the past three years running.
2010 marks the fiftieth anniversary of Charles D Keeling′s first publication of atmospheric CO2 measurements and another key part of the conference is the need for better monitoring of greenhouse gases and setting targets for the future. Each country is now obliged to report their emissions but there appear to be discrepancies in the amount of pollution countries report and actual emissions in the atmosphere.
Professor Nisbet will explain how greenhouse gas emissions can be accurately measured by ground-based monitoring systems, what trends are being identified and what needs to change to ensure that there can be confidence in emission figures in future.
The conference aims to explore the implications of the latest assessments of climate change impacts and the potential adaptations, shaping the agenda for the next two decades.
