Technology will not “come to the rescue” and reverse greenhouse gas emissions, experts have warned. In a new report, a group of prominent European scientists has emphasised the importance of focusing on reducing emissions in order to meet global warming targets. Technologies that remove greenhouse gases from the atmosphere have been singled out as a major component in the struggle to keep the global temperature rise below the 2C decided in the Paris climate agreement. However, the new report has highlighted the shortcomings of these technologies, describing expectations placed on them as “seriously over-optimistic”.

Ways of sucking carbon dioxide from the air will not work on the vast scales needed to beat climate change, Europe’s science academies warned on Thursday. From simply planting trees to filtering CO2 out of the air, the technologies that some hope could be a “silver bullet” in halting global warming either risk huge damage to the environment themselves or are likely to be very costly. Virtually all the pathways laid out by the UN’s Intergovernmental Panel on Climate Change (IPCC) to reach the targets in the Paris agreement require huge deployment of so-called negative emissions technologies (NETs) in the second half of the century.

Global temperatures could break through the internationally agreed upper 1.5C limit within the next five years, according to a forecast by British scientists that raises fresh questions about the world’s efforts to tackle climate change. The Met Office forecasting service said that in the period from 2018 to 2022, annual global average temperatures are likely to exceed 1C above pre-industrial levels and could top the 1.5C threshold set as an aspiration by the global Paris climate change deal in 2015.
