Fossil fuels – coal, oil and gas – account for most greenhouse gas emissions, which trap the sun’s heat, leading to global warming and climate change. Last year, global averaged concentrations of the most important greenhouse gas – carbon dioxide…
The landmark decision comes as heat-trapping greenhouse gas concentrations are at record levels – “higher than at any time over the last 800,000 years”, WMO warned. Data from Earth and space The new Global Greenhouse Gas Watch will combine observations from Earth and from space with modelling, to fill critical information gaps. It will build…
The WMO initiative would create a network of ground-based measurement stations that can verify worrying air quality data that’s been flagged by satellites or airplanes, potentially in the next five years. “At present, there is no comprehensive, timely international exchange of surface and space-based greenhouse gas observations,” the UN agency said, as it urged “improved (international) collaboration” and…
