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

Extreme heat wave Australia adds new colour to weather chart – forecast up to 54 degrees Celsius!

As red tones cannot get much darker when you approach black, the Australian Bureau of Meteorology had to resort to introducing new colours on their weather forecast maps for next week, when inland temperatures in South Australia can locally reach … Continue reading

Local Indonesian El Niño progression, possibility strong wildfire season Borneo, Sumatra

Over the course of 2012 ENSO has moved from La Niña to El Niño state. Various ENSO forecasting models (see NOAA NECP, IRI ensemble below) now show Pacific equatorial SSTs anomalies will remain positive for the remainder of 2012 – … Continue reading

Climate change caused 2,500 year collapse of Panamanian coral reef

partly dead coral reefClimate change drove coral reefs to a total ecosystem collapse lasting thousands of years, according to a paper published this week in Science. The paper shows how natural climatic shifts stopped reef growth in the eastern Pacific for 2,500 years. The reef shutdown, which began 4,000 years ago, corresponds to a period of dramatic swings in the El Niño-Southern Oscillation (ENSO). “As humans continue to pump greenhouse gases into the atmosphere, the climate is once again on the threshold of a new regime, with dire consequences for reef ecosystems unless we get control of climate change,” said coauthor Richard Aronson, a biology professor at Florida Institute of Technology.

Stopping economic growth for the sake of the climate

A United States and Spanish research team has conducted a study into the most likely causes of climate change and came to a rather surprising conclusion. The most feasible manner of stopping climate change is halting economic growth. Or changing … Continue reading

Earlier heat stress helps corals overcome climate change

Coral reefA team of international scientists working in the central Pacific has discovered that coral which has survived heat stress in the past is more likely to survive it in the future.

The study, published March 30 in the journal PLoS ONE, paves the way towards an important road map on the impacts of ocean warming, and will help scientists identify the habitats and locations where coral reefs are more likely to adapt to climate change.
