Climate Change & Anthropocene Extinction 30: Heavy breathing tropical forests under record heat

Today the WMO announced that the atmospheric CO2 concentration last year rose at a record high speed: +3.3 ppm – jumping from 400.0 ppm in 2015 to 403.3 in 2016. The annual average rise is close to 2 ppm. A … Continue reading

Real Global Temperature Trend, p15 – 2016-2020 global forecast: 5-year average temperatures above 2015 record, despite La Niña

It’s raining climate records since late 2014. That has increased to a proper storm from October 2015 – the first month to show global temperature anomalies of more than 1 degree above the 1951-1980 climate average (so higher still above … Continue reading

2015 El Niño produces new climate record: 3 simultaneous Pacific category 4 hurricanes

Small Island States don’t (yet*) make global headlines, but this NASA picture shows a new Pacific climate record, which has a story for us all.

NASA climate model forecast shows 2015 El Niño to go off the charts during Paris climate summit

According to the world’s best-established dynamical climate models (e.g. NOAA NCEP, NASA GMAO) the 2015 El Niño is set to peak to dramatic proportions just before and possibly also during the all-important Paris climate summit – the UNFCCC’s ‘COP21′ – … Continue reading

A new ‘super El Niño’ would peak ~0.2 Celsius above the one in this graph

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

Two hottest years ever: 2014 will set new world temperature record – and 2015 will break it

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

A weak or a strong El Niño ahead? Hint: we live in a 3D world

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

NOAA forecasts El Niño increase during 2nd half 2014, moderate El Niño in boreal summer, possibly ‘strong’ in autumn

According to NOAA’s NCEP climate prediction model the Pacific Niño 3.4 region may experience more than a +1.5 degrees Celsius sea surface temperature anomaly, then officially qualifying as ‘strong El Niño’ – shown in graph below.

Ensemble El Niño forecast speeding up. El Niño during boreal summer 2014, possibly >+0.5C already by June

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
