The 'safe' threshold for global warming will be passed in just 6 years, scientists say (space.com)

New research suggests we have just six years left to limit global warming to 1.5 degrees Celsius, and two decades to keep temperatures below the 2 C threshold in the Paris Agreement.
Global carbon emissions are on track to exceed safe limits by 2030 and unleash the worst effects of climate change, new research suggests. This means we have just six years to change course and dramatically reduce greenhouse gas emissions.
A new estimate of our remaining carbon budget — the amount of carbon dioxide we can produce while keeping global temperatures below a dangerous threshold — indicates that, as of January, if we emit more than 276 gigatons (250 metric gigatons) of CO2 we will hit temperatures 1.5 degrees Celsius (2.7 degrees Fahrenheit) above preindustrial levels. The researchers found that if emissions continue at the current rate, we will cross this threshold before the end of the decade, according to a study published Monday (Oct. 30) in the journal Nature Climate Change.
"Our finding confirms what we already know — we're not doing nearly enough to keep warming below 1.5 degrees C," study lead author Robin Lamboll, a researcher at the Center for Environmental Policy at Imperial College London, said in a statement. "We can be ever more certain that the window for keeping warming to safe levels is rapidly closing."
