Summary
Engineers say a forest of 100,000 artificial trees could be deployed within 10to 20 years to help soak up the world's carbon emissions.The trees are among three geo-engineering ideas highlighted as practical in a new report.The authors from the Institution of Mechanical Engineers say that withoutgeo-engineering it will be impossible to avoid dangerous climate change. The report includes a 100-year roadmap to decarbonise the global economy. Launching the report, lead author Dr Tim Fox said geo-engineering should not be viewed as the only means to bring about a climate change.Rather, it should be used in conjunction with efforts to reduce carbon emissions and to adapt to the effects of climate change.Many climate scientists calculate that the world has only a few decades to reduce emissions before there is so much carbon dioxide in the atmosphere that a dangerous rise in global temperature is inevitable.
