CLIMATE CHANGE ROUND UP FOR THE WEEK ENDING: JANUARY 19, 2019
Climate change and deforestation are putting more than half the world’s wild coffee species at risk of extinction, including the popular commercial coffees Arabica and Robusta, scientists warned on Wednesday.
Research published by experts at Britain’s Royal Botanic Gardens at Kew found that current conservation measures for wild coffee species are not enough to protect their long-term future.
The impact of climate change on roads and other crucial structures in Canada’s North is likely to be even greater than feared, says new detailed research.
“These are greater impacts than anything I’m aware of,” said John Pomeroy, head of the University of Saskatchewan’s Global Water Futures program and lead author on a recently published paper.
By now, it’s clear that climate change poses environmental risks beyond anything seen in the modern age. But we’re only starting to come to grips with the potential economic effects.
Using increasingly sophisticated modeling, researchers are calculating how each tenth of a degree of global warming is likely to play out in economic terms. Their projections carry large bands of uncertainty, because of the vagaries of human behavior and the remaining questions about how quickly the planet will respond to the buildup of greenhouse gases.
A government report in November raised the prospect that a warmer planet could mean a big hit to G.D.P. in the coming decades.
