Britain’s national weather service says this year’s global average temperature is on track to reach 1 degree Celsius (1.8 degrees Fahrenheit) above pre-industrial levels for the first time. That’s a symbolically important level as it’s halfway to the 2 degrees C (3.6 degrees F) that governments have set as a limit to avoid dangerous levels of warming.
The Met Office’s projection Monday was based on January-September data. Officials said the El Nino weather phenomenon is having a strong impact this year, but added ”it’s clear that it is human influence driving our modern climate into uncharted territory.”
They noted it doesn’t mean every year from now will be at least 1 degree warmer ”as natural variability will still play a role.”
