Gloom from the climate-change front line
Aug 10th 2019AFTER 29 HOURS of uninterrupted negotiations the latest report from the Intergovernmental Panel on Climate Change (IPCC), on how alterations in land use are contributing to such change, was gavelled through in Geneva on the afternoon of August 7th. When, minutes later, your correspondent asked to speak with some of the researchers, she was informed they had “gone to bed”. The report these exhausted delegates produced—all 1,300 pages of it—fires another warning shot about the state of the planet and the way people are transforming virtually every corner of every continent. Human activities affect roughly three-quarters of Earth’s ice-free land, with huge consequences for the climate.Land masses are natural carbon sinks, absorbing greenhouse gases by a variety of processes, including photosynthesis. They also produce such gases—for instance, when vegetation decomposes or burns. By conserving some ecosystems and destroying others to make way for pastures and fields, or chopping down trees for timber, human activities on the land add an extra layer of complexity to already complex natural cycles.Choose us for news analysis that respects your time and intelligenceSubscribe to The EconomistWe filter out the noise of the daily news cycle and analyse the trends that matterWe give you rigorous, deeply researched and fact-checked journalism.
