1.5? – Never was…
What is the argument against reason and logic?
The latest UN Environment Programme (UNEP) emissions gap report suggests that unless the world begins to rapidly reduce greenhouse gas emissions the 1.5C goal of the Paris Agreement “will slip out of reach,”
The figure below, adapted from one created by CICERO’s Dr Robbie Andrews, shows emission trajectories to limit warming to below 1.5C in the absence of net-negative emissions. The different lines show the emissions reductions that would be required if emissions had peaked in each year, between 2000 and 2026, with the current year (2019) highlighted in grey.
IF
If emissions had peaked and begun to decline after the year 2000, the 1.5C target would have been much easier to achieve, only requiring reductions of around 3% per year. By contrast, limiting warming to below 1.5C starting in 2019, without net-negative emissions, would require a 15% cut each year through to 2040.
Yeah, not gunna happen…
If emissions continue at current levels for another few years, then the only way to limit warming to below 1.5C in the absence of net-negative emissions would be to immediately cut all global emissions to zero.
