June 2015 Hottest on Record: Super El Niño, Heatwaves, Record Precipitation and Drought

July 20, 2015 by Tom Schueneman

Climate Change and Record Whether

According to data released this week by the Japan Meteorological Agency, June 2015 was the hottest June in the global record. And on Wednesday NASA reported similar temperature findings, with 2015 tied with 1998 as the warmest on record.[read more]

Bad News For California: NOAA Lowers Chance Of El Niño To 65%, Predicts A Weak One

August 14, 2014 by Joseph Romm

California and Environmental Risk

The NOAA previously said the chances of an El Niño developing this year were at almost 4 out of 5. There was some evidence suggesting it might be a strong El Niño, the kind that generally brings a lot of rain to California. But the best chance for ending the brutal California drought seems to be disappearing.[read more]

More Evidence Global Surface Temperatures Poised To Rise Rapidly

July 26, 2014 by Joseph Romm

Potential Surface Temp Jump

A new study finds that when climate models factor in the temporary warming and cooling impact of El Niño and La Niña, they accurately predict recent global warming. And that is consistent with recent studies that led one climatologist to say, “Global temperatures look set to rise rapidly.”[read more]

Hottest Spring On Record Globally, Reports Japan Meteorological Agency

June 21, 2014 by Joseph Romm

Hottest Spring Ever

The Japan Meteorological Agency (JMA) reported Monday that March-May was the hottest in more than 120 years of record-keeping. It was also the hottest May on record. This is especially noteworthy because we’re still waiting for the start of El Niño.[read more]

El Niño Chances Jump To Near 80%, Add In Global Warming And We Face Record Heat

May 13, 2014 by Joseph Romm

Weather Patterns and Warming Trends

The chances of an El Niño developing this year are now at almost 4 out of 5. The chart above from NASA makes clear El Niños are generally the hottest years on record — since the regional warming adds to the underlying man-made global trend.[read more]

Does El Niño Plus Global Warming Equal Global Temperature Records In 2014 And 2015?

April 26, 2014 by Joseph Romm

Global Warming and Weather Risk


An El Niño appears increasingly likely this year, according to the National Oceanic and Atmospheric Administration (NOAA) and Australia’s Bureau of Meteorology (BOM). If it starts relatively quickly, then 2014 could well be the hottest year on record.[read more]

Is A Super El Niño Coming That Will Shatter Extreme Weather And Global Temperature Records?

March 28, 2014 by Joseph Romm

Super El Niño

Signs are increasingly pointing to the formation of an El Niño in the next few months, possibly a very strong one. When combined with the long-term global warming trend, a strong El Niño would mean 2015 is very likely to become the hottest year on record by far.[read more]

Australian weather bureau: “Central Pacific Ocean surface temperatures are now at their warmest level since the El Niño of 1997-98″

December 25, 2009 by Joseph Romm

That’s the the 7-day (12/14-12/20) sea surface temperature (SST) anomaly map from Australia’s Bureau of Meteorology (ABM).  Their El Niño-Southern Oscillation report finds: Pacific Ocean temperatures remain at levels typical of a mature El Niño….  As a result, central Pacific Ocean surface temperatures are now at their...[read more]

Dust storm in Australia

September 24, 2009 by Simon Donner

Southeastern Australia is recovering from the worst dust storm in decades, that damaged farmland and practically closing down Sydney and the surrounding area.The satellite image, from NASA's terrific Earth Observatory web-site, shows the brown dust cloud stretching from Queensland far south into New South Wales, before it moved off the...[read more]

The path of Tropical Storm Danny

August 28, 2009 by Simon Donner

I'll have more on what we should be saying about climate change shortly (there are couple interesting responses at the Energy Collective cross-post) .The model projections at right show that fourth named tropical storm of the Atlantic season is expected to take a path quite similar to that of Bill, interesting given how El Nino events...[read more]

NOAA: “El Niño is expected to strengthen and last through” winter — record temperatures are coming

August 6, 2009 by Joseph Romm

NOAA’s National Weather Service Climate Prediction Center released its monthly El Niño/Southern oscillation (ENSO) Diagnostic Discussion: Synopsis: El Niño is expected to strengthen and last through the Northern Hemisphere Winter 2009-2010. A weak El Niño was present during July 2009, as monthly sea surface temperatures (SST)...[read more]

The link between heat waves and global warming

July 28, 2009 by Simon Donner

In Saturday's Globe and Mail, Rex Murphy had yet another obtuse column speculating about global cooling, spurred by Toronto's cool, wet summer. While the errors in Murphy's supposedly ironic columns have not quite reached the level of George Will, in which a full-on intervention with the editorial board of the Washington Post now appears...[read more]

El Nino and the likelihood of mass coral bleaching

July 23, 2009 by Simon Donner

The seasonal forecasting system recently developed by NOAA Coral Reef Watch suggests that coral reefs in the Caribbean and in part of the central equatorial Pacific (the Line Islands, including Kiritimati or "Christmas Island") are at risk of coral bleaching in the coming months due to warm ocean temperatures. The forecast is due to the...[read more]

Surprising Conclusions from Unsurprising Results

July 23, 2009 by Michael Tobis

The denialists are making a big deal about the new paper, Influence of the Southern Oscillation on tropospheric temperature, (McLean, de Freitas and Carter).It's a data analysis paper, and pretty much a no-brainer. It shows that global mean temperature variance is dominated by the El Nino/Southern Oscillation index (which most...[read more]

NOAA: Fourth warmest May on record, model predicts a long and strong El Niño

June 17, 2009 by Joseph Romm

Fast on the heels of the fifth warmest April on record, NOAA’s National Climatic Data Center reports: Based on preliminary data, the globally averaged combined land and sea surface temperature was the fourth warmest on record for May, the fifth warmest for boreal spring (March-May), and tied with 2003 as the sixth warmest January-May...[read more]
