This is the graph of the world’s best-established temperature dataset, of NASA GISS. It shows another good representation of the 1997-1998 El Niño world average temperature peak. Recent years have been net influenced by La Niña state, as shown in … Continue reading
Shown below is a graph of the satellite-derived University of Alabama global temperature dataset (those fellows that each year in early January beat NOAA/NASA/MetOffice/WMO etc by being the first to say ‘how warm it was’). Clearly visible is the peak … Continue reading
We expect a new global average temperature record for 2014 to be broken in 2015. Where will all the extra heat go?
El Niño Southern Oscillation index: duration and intensity of La Niña and El Niño years. El Niño is usually defined as a positive temperature anomaly in the east and central tropical Pacific. Another way to express the climate phenomenon is … Continue reading
If we take another look at the IRI ensemble forecast for El Niño some members show a clear and speedy rise in East Pacific tropical ocean temperatures. Before we conclude ‘El Niño ahead’ during northern hemisphere summer and autumn let’s … Continue reading
El Niño forecast, IRI ensemble: leading climate models show El Niño during summer 2014 Compared to last month’s forecast the IRI climate model ensemble shows a somewhat faster development of a positive ENSO state and clear indications of El Niño … Continue reading
Falling snow flakes are humbling. Not just because of their beauty, but also because of their gentle ability to completely paralyse a developed and overpopulated country with traffic jams, clogged railroad switches and closed runways. But although that (together with … Continue reading
Ocean level rise is known as one of the most disquieting effects of global warming, with more than three billion people living on the coast or less than 200 kilometres land inward and one tenth of the world population living … Continue reading
