MET Office Lowers Predicted Temperatures
So much for "it's worse than we thought..."
Old Forecast:
Global average temperature is expected to rise to between 0.36 °C and 0.72 °C (90% confidence range) above the long-term (1971-2000) average during the period 2012-2016, with values most likely to be about 0.54 °C higher than average (see blue curves in the Figure 1 below).
From 2017 to 2021, global temperature is forecast to rise further to between 0.54 °C and 0.97 °C, with most likely values of about 0.76 °C above average. The warmest year in the 160-year Met Office Hadley Centre global temperature record is 1998, with a temperature of 0.40 °C above the long-term average. 2009 had a temperature of 0.32 °C above average. The forecast trend of further global warming is largely driven by increasing levels of greenhouse gases.
New Forecast:
Global average temperature is expected to remain between 0.28 °C and 0.59 °C (90% confidence range) above the long-term (1971-2000) average during the period 2013-2017, with values most likely to be about 0.43 °C higher than average (see blue curves in the Figure 1 below).
The warmest year in the 160-year Met Office Hadley Centre global temperature record in 1998, with a temperature of 0.40°C above long-term average. The forecast of continued global warming is largely driven by increasing levels of greenhouse gases.
