What is Global Warming? What is Climate Change?

How could we answer the following questions? In your lifetime (the last 14 years) have temperatures in the UK Increased Decreased Or remained stable ? In your lifetime (the last 14 years) has rainfall in the UK Increased Decreased Or remained stable ?

Using historical data to identify trends and make predictions. The met office has been collecting and collating data since Their website enables you to view data from any of their stations indicated with the red dot.

The bigger picture

Average rainfall in the UK past 100 years

Could the recent flooding have been predicted? Changes to the rainfall pattern have been observed - these are sometimes more extreme (which means that locations are either a lot wetter or a lot drier than they used to be). At other times the rainfall pattern is out of season. The extreme rainfall in the UK during the summer of 2007 is an example of this. However, in general, UK summers are getting drier and winters are getting wetter.

Climatic Investigations Should we expect a hot summer this year? What could indicate a hot summer is on the way?

Weather Forecast for 2014 Perhaps hard to believe during the wettest winter in a hundred years, but scientists are 75 per cent certain that 2014 will be the hottest summer on record. The weather is being linked to the El Niño pattern, which occurs when waters on the Pacific equator are unusually warm, which can lead to disruptive changes in ocean and wind currents across the world. The researchers hope that the longer forecasts could be used to help countries prepare more effectively for the potentially turbulent weather changes El Niño can bring.

El Niño El Niño is a set of phenomena caused by periodic changes in the ocean atmosphere system in the tropical Pacific Ocean. During El Niño, the trade winds, which usually blow warm surface waters to the west, die down or even reverse. When the wind stops blowing the warm water to the west, the warm water pools in the east, triggering a number of effects in the atmosphere and ocean.

Detecting El Niño One way to detect El Niño is to look at sea surface temperature (SST). The US Ocean and Coastal and Observation system maintains numerous data sets that can be used to study El Niño. We are going to look at some today!

ENSO Cycle: Recent Evolution, Current Status and Predictions Update prepared by Climate Prediction Center / NCEP 18 February 2014

SST Departures ( o C) in the Tropical Pacific During the Last 4 Weeks During the last 4-weeks, equatorial SSTs were above average in the western Pacific and below-average across the central and eastern Pacific.

SST Outlook: NCEP CFS.v2 Forecast Issued 18 February 2014 The CFS.v2 ensemble mean (black dashed line) predicts ENSO-neutral through the N.H. spring 2014 followed by El Niño starting in May-July (MJJ) 2014
