•Our planet is suffering an energy imbalance and is steadily accumulating heat (Hansen 2005, Murphy 2009, Schuckmann 2009, Trenberth 2009)
•Animal and plant species are responding to earlier springs. Eg - earlier frog breeding, bird nesting, earlier flowering, earlier migration of birds and butterflies (Parmeson 2003)
•The distribution of tree lines, plants, birds, mammals, insects, fish, reptiles, marine invertebrates are shifting towards the poles (Parmeson 2003)
•Arctic permafrost is degrading (Anisimov 2006) plus warming at greater depths in the permafrost (Stieglitz 2003)
•Global sea level rise is accelerating (Church 2006)
•Antarctic ice loss is accelerating (Velicogna 2009), even from East Antarctica which was previously thought to be too stable to lose ice mass (Chen 2009)
•Greenland ice loss is accelerating (Velicogna 2009, van den Broeke et al 2009)
•Glaciers are shrinking globally at an accelerating rate (WGMS 2008)
•Arctic sea-ice loss is accelerating with the loss rate exceeding model forecasts by around a factor of 3 (Stroeve 2007).
•The height of the tropopause is increasing (Santer 2003, press release)
•Jet streams are moving poleward (Archer 2008, Seidel 2007, Fu 2006)
•The tropical belt is widening (Seidel 2007, Fu 2006)
•There is an increasing trend in record hot days versus record cold temperatures with currently twice as many record hot days than record cold temperatures (Meehle 2009, see press release).
