NASA, NOAA: 2015 Hottest Year on Record


January Drought Map

Jan 23, 2015 (San Diego) The National Aeronautics and Space Administration (NASA) and the National Oceanic and Atmospheric Administration (NOAA) have come out and said it: 2015 was the hottest year on record. Those records go back 136 years.

CNN reports that “the average temperature across the entire planet 1.62˚F (0.90˚C) above the 20th century average, more than 20% higher than the previous highest departure from average.”

We know our fall here in sunny San Diego was pretty mild. This reporter was in Cleveland in October and there was no now to be seen. For that matter, temperatures were pretty mild. (Part of this is El Nino). But we also know that we are in the mists of a drought.

The trend continues to be for a slowly heating up planet, with more dramatic weather events to come. Droughts and floods will become more dramatic, as part of the effect.

Due to El Nino United Kingdom weather forecasters also expect 2016 to be even warmer than 2015.

Man-made global warming, combined with a smaller effect from El Niño from unusually warm waters in the tropical Pacific Ocean feature within our forecast. The forecast is based on the key drivers of global climate, but it doesn’t include random events, such as large volcanic eruptions – which can cause a temporary cooling effect.

The outlook for 2016 is warmer than the Met Office’s forecast for 2015, which had a range of 0.52 °C to 0.76 °C and a central estimate of 0.64 °C (using the 1961-1990 long-term average). Data from Jan-Oct shows the global mean temperature for this year so far is 0.72 °C [note 2] (+/- 0.1 °C)

This is partly climate change, which is man made, and to a lesser extent El Nino, which is more dramatic this year than it was in 1997-8. So as the year comes and goes, expect more heat events, and due to El Nino, perhaps, more floods.
