'Timely wake-up call': Greenhouse gas emissions at all-time high

The 1.5C temperature increase limit that scientists say is needed to stave off the very worst climate-change fallout is currently well off track.

Global warming brought on by human activity is continuing at an unprecedented rate over the past two years, with greenhouse gas emissions at an all-time high, Irish and British scientists have calculated.

The 1.5C temperature increase limit that scientists say is needed to stave off the very worst climate-change fallout is currently well off track, according to Maynooth University professor of physical geography (climate change) Peter Thorne.
