Climate change news for Monday 19th of March 2018
"Scientists [writing in the current issue of 'Nature'] have outlined plans to build a series of mammoth engineering projects in Greenland and Antarctica to help slow down the disintegration of the planet’s main glaciers. The controversial proposals include underwater walls, artificial islands and huge pumping stations that would channel cold water into the bases of glaciers to stop them from melting and sliding into the sea"
"Ocean acidification poses a chronic threat to coral reefs… We present an estimate of [ecological] community-scale calcification sensitivity… Near-future reductions in the aragonite saturation state will compromise the ecosystem function of coral reefs."
"The escalation in small hydropower development [in Brazil] comes at a time when large dams are falling out of favour as a source of renewable energy: mounting evidence points to... impacts [that include] contributing to carbon emissions"
"Researcher John Pomeroy is braving frigid winter temperatures to climb a... tower in the shadow of Alberta's Fortress Mountain... Precipitation patterns have been changing along with the general climate in this mountain range, he says"
"Rising carbon dioxide concentrations... are rapidly warming and acidifying our oceans… One of the most calcium‐carbonate‐dependent species globally (Calloria inconspicua) [is] highly resilient to environmental change"

"Research increasingly suggests that [Bio-Energy with Carbon Capture and Storage] is not feasible at the scale necessary to make a real dent in global climate goals — at least, not without causing massive... disruptions"
