UNEP study: small number of measures targeting black carbon and tropospheric ozone could yield immediate climate benefits

Green Car Congress

The climate change benefit is estimated for 2050 and human health and crop benefits are for 2030 and beyond. Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. °C (within a likely range of 0.2-0.7 Click to enlarge.

Cutting Non-CO2 Pollutants Can Delay Abrupt Climate Change; The Fast Action Climate Agenda

Green Car Congress

Shown are the tipping elements [large-scale components of the Earth’s system] and the temperature threshold range that initiates the tipping. Cutting HFCs, black carbon, tropospheric ozone, and methane can buy us about 40 years before we approach the dangerous threshold of 2°C warming. From Molina et al. Earlier post.) Mario Molina. (Dr.

German-Chilean consortium investigating new ways of reducing arsenic in copper concentrates: ReAK

Green Car Congress

Previously, the fact that these compounds are water-soluble never presented any problems since the Atacama Desert is one of the driest regions in the world. However, climate change has caused an increase in rainfall in recent years, which now raises the issue of environmental contamination. —Anna-Lisa Bachmann.
