March records smashed in Australia
Global temperatures leapt in February, lifting warming from pre-industrial levels to beyond 1.5 degrees, and stoking concerns about a "climate emergency".
According to NASA analysis, average temperatures last month were 1.35 degrees above the norm for the 1951-1980 period.
They smashed the previous biggest departure from the average - set only in the previous month - by 0.21 degrees.
"This is really quite stunning ... it's completely unprecedented," said Stefan Rahmstorf, from Germany's Potsdam Institute of Climate Impact Research and a visiting professorial fellow at the University of NSW, noting the NASA data as reported by the Wunderground blog.
The blog's authors, Jeff Masters and Bob Henson, described February's spike as "a true shocker, and yet another reminder of the incessant long-term rise in global temperature resulting from human-produced greenhouse gases".
The monster El Nino event had contributed to the current record run of global temperatures by increasing the area of abnormally warm water in the central and eastern Pacific.
Compared with the rival record giant El Nino of 1997-98, global temperatures are running about 0.5 degrees hotter.
"That shows how much much global warming we have had since then," Professor Rahmstorf said.
The first half of March is at least as warm, he added, and it means temperatures "are clearly more than 1.5 degrees above pre-industrial levels".
Yep, if you make the past colder, good chance its gonna be hotter now.
Who's made the past colder.
The earth is supposed to be cooling.
1. BEST et al
2. Hiatus <> cooling. El Nino was alway going to be a warm year.

The huge jump in global temperatures has been picked up and analysed by many media orgs.
There is a a longer story on this blog which picks up on how the extreme global temperatures have manifested around the world.
Interestingly the data set is so overwhelming Roy Spencer has agreed with the the NASA scientists.

Extreme El Nino event, as the BoM website attests.
Runaway
Though not being communicated, the alarming data above for 30 May 2015, looks like the state of the climate is set up for feedback runaway global climate.
From the very start the big concern about global warming has been the possibility of a 'runaway' global warming and climate change.
'Runaway' (self accelerating) global heating and climate change is the planetary tipping point of all the many tipping points combined and self reinforcing .
This is the greatest single danger to the survival of humanity and also the survival of potentially almost all life on the planet. A global heating runaway wiping almost most life we know is possible- because it happened 250 million years ago in the End Permian extinction event and 55 million years ago with the Paleocene-Eocene thermal maximum (PETM). Current research confirms both of these extinction events were driven by very large emissions of carbon to the atmosphere.
The PETM is the closest distant past analog to our GHG emissions global warming situation today. Research published October 2013 by Morgan Schaller and James Wright leads to their definite finding that following a doubling in carbon dioxide levels, the surface of the ocean turned acidic over a period of weeks or months and global temperatures rose by 5 degrees centigrade – all in the space of about 13 years. Scientists had previously thought this process happened over 10,000 years.
These mass extinction events involve the emission of an enormous emission of carbon as CO2 and methane. In the Arctic several times atmospheric methane is stored frozen in permafrost and subsea floor frozen solid methane gas hydrate. The permafrost is thawing as the Arctic temperature rapidly increases (Arctic amplification). Arctic methane hydrate is destabilizing in at least three locations, mainly a process that has been going on for a long time, but that ocean warming will make worse
Yep we do have an El Nino event. Yes climate scientists expected an increase in global temperatures as a consequence.
Problem is the magnitude of the increase is way out of line with previous experience. It also comes on top of a steadily increasing rise in temperature associated with global warming unconnected with El Nino.
The big concern is if we are reaching the critical tipping points in a number of areas. For example the warming of the Arctic oceans and the Tundra is releasing millions of tons of methane and methane hydrates. There is a risk that this current burst of intense warming could create an unstoppable flow of methane that would create runaway global warming and cook our planet within 20 years.
Yep. Certainly been hot in the last couple of months - all around the world

What a jump in Jan-Feb 2016 !
Well Bas the heat is still on and I think the news of the hottest February on record will be left high and dry by the numbers coming out of March. An interesting point by Australia's Chief Climate Scientist Alan Finkel last night on Q&A , he says basically whatever we are doing to reduce our emissions is making zero difference to holt the climbing World Temperatures.
Would be interesting to know the areas of the increase in emissions.
More coal fired power stations, bushfires or volcanos ?
Who has the answer ?
A couple of nukes will produce some global cooling. South Korea are keen to help.
