green screen noun [C]
a large steel grid densely covered with ivy thought to act as a barrier to air pollution

Schools are being pressured into buying expensive ‘green screens’ to shield children from air pollution despite concerns that they are not the best solution and may make little overall difference to health … More than a dozen schools in London, Manchester and Leeds have already installed green screens and at least 30 more have applied to the Greater London Authority for grants of up to £35,000 to buy them after they were recommended by air quality audits.

precipitation whiplash noun [U]
UK /prɪˌsɪp.ɪˈteɪ.ʃən.ˈwɪp.læʃ/ US /priːˌsɪp.əˈteɪ.ʃən.ˈwɪp.læʃ/
a period of very dry weather followed by a period of very wet weather, thought to be caused by the effects of climate change

Abrupt transitions in California from a parched winter to a soggy one … will become more common if greenhouse gases continue to increase, according to a study published Monday in Nature Climate Change. This “precipitation whiplash” has implications for both wildfire and flood risk.

climate gentrification noun [U]
UK /ˈklaɪ.mət.ˌdʒen.trɪ.fɪˈkeɪ.ʃən/ US /ˈklaɪ.mət.ˌdʒen.trə.fəˈkeɪ.ʃən/
the process by which a place that is thought to be less at risk of the effects of climate change turns from a poor area to a richer one

The study finds considerable evidence of climate gentrification, and for the elevation hypothesis in particular. Properties at high elevations have experienced rising values, while those at lower elevations have declined in value. In fact, elevation had a positive effect on price appreciation in more than three-quarters of the properties and 24 of the 25 separate jurisdictions the authors examined.
