hot years soon will be normal
2015 — the Earth’s warmest year on record — could be just another average year in as soon as 10 years if carbon emissions continue to rise at their current rate.
What's even more sobering is that no matter what action we take, the global annual average temperature of 2015 will be the norm by 2040, the study said.
However, while the planet as a whole is locked in to this level of warming, the study said it's still possible for certain regions to prevent record-breaking warmth from becoming the standard. But it will take "immediate and strong action on carbon emissions" for this to happen, the study said.
"Based on a specific starting point, we determined a new normal occurred when at least half of the years following a record year were cooler and half warmer. Only then can a new normal state be declared," Lewis said.
