Climate change: Worst emissions scenario ‘misleading’

Climate change: Worst emissions scenario ‘misleading’

Science
The worst-case scenario for emissions of CO2 this century is no longer plausible, say researchers.Referred to as "business as usual", the scenario assumes a 500% increase in the use of coal, which is now considered unlikely.Climate models suggest that this level of carbon could see warming of up to 6C by 2100, with severe impacts.Researchers say that on current trends, a rise in temperatures of around 3C is far more likely.How has this confusion come about?About 10 years ago, ahead of the fifth assessment report from the Intergovernmental Panel on Climate Change (IPCC), researchers developed four different scenarios to describe how carbon emissions might change over the rest of this century. One of these clumsily titled "Represen...

Climate change: UK has ‘one shot’ at success at Glasgow COP26

Science
If the Glasgow climate conference fails to deliver, it could mark the end of the global approach to tackling the problem.COP26 in November will see around 200 world leaders meet to agree a new, long term deal on rising temperatures. But according to Claire O'Neill, the president of COP26, the UK has "one shot" at making it a success.She told a BBC documentary that if Glasgow fails, people will question the whole UN approach. BBC World Service Discovery - 2020: A year to save the Planet? Five things we've learned from Madrid climate talks COP26 marks a critical moment for the UN in the long running effort to find a global solution to climate change. As part of the Paris climate deal, agreed in 2015, countries are meant to update t...
NHS staff urged to help service tackle climate change

NHS staff urged to help service tackle climate change

Health
NHS staff are being encouraged to drive to work less and bring in reusable cups and bottles to help the health service tackle climate change.The suggestions are part of an NHS plan to cut carbon emissions to net zero and reduce air pollution. Hospitals will also be told to switch to less-polluting anaesthetic gases and reduce emissions from buildings.The plan follows the launch of Climate Assembly UK this week, which is looking at how the UK can best get to net zero.The government has committed to the UK reaching the target - where the same volume of greenhouse gases is being emitted as is being absorbed through offsetting techniques like forestry - by 2050.

Space mission to reveal ‘Truths’ about climate change

Space mission to reveal ‘Truths’ about climate change

Science
The UK is going to lead a space mission to get an absolute measurement of the light reflected off Earth's surface.The information will be used to calibrate the observations of other satellites, allowing their data to be compared more easily.Called Truths, the new spacecraft was approved for development by European Space Agency member states in November.Proponents of the mission expect its data to help reduce the uncertainty in projections of future climate change.Scientists and engineers met on Tuesday to begin planning the project. Industry representatives from Britain, Switzerland, Greece, the Czech Republic and Romania gathered at Esa's technical centre in Harwell, Oxfordshire.The agency has ...
Climate change: Last decade confirmed as warmest on record

Climate change: Last decade confirmed as warmest on record

Science
The 10 years to the end of 2019 have been confirmed as the warmest decade on record by three global agencies. According to Nasa, Noaa and the UK Met Office, last year was the second warmest in a record dating back to 1850.The past five years were the hottest in the 170-year series, with the average of each one more than 1C warmer than pre-industrial. The Met Office says that 2020 is likely to continue this warming trend.2016 remains the warmest year on record, when temperatures were boosted by the El Niño weather phenomenon. Today's data doesn't come as a huge surprise, with the World Meteorological Organization (WMO) signalling at the start of last December that 2019 likely marked the end of the warmest decade on record.
