Record Heat in June Extends Globe’s Streak to 340 Months

June was one of the hottest such months on record globally, based on newly released data from NASA and the National Oceanic and Atmospheric Administration (NOAA). The month extended the unbroken string of warmer-than-average months to 340, or a stretch of more than 28 years. That means that no one under the age of 28 has ever experienced a month in which global average temperatures were cooler than average (based on the 20th century average).

Global average surface temperatures during June were either the second or the fifth-warmest on record for the month, based on analyses by NASA and NOAA, respectively. The two agencies keep tabs on global temperature trends using large networks of surface monitoring stations and statistical approaches to fill in gaps where stations are sparse, but they use slightly different methods to analyze the data, which can result in slight differences in their rankings.

June continued the long-term warming trend tied to manmade greenhouse gas pollution as well as natural climate variability. The planet has not recorded a single month with temperatures below the 20th century average since February 1985, when the cult classic film “The Breakfast Club” was released, and the last year with a cooler-than-average June was in 1976. This year so far is tied with 2003 as the seventh-warmest year on record, NOAA said.

Last month featured unusually wet conditions in the eastern U.S., and tragically wet conditions in northwest India, where rainfall that was 200 percent of average inundated parts of the state of Uttarakhand, killing nearly 6,000 and causing widespread destruction. Areas that experienced higher-than-average temperatures during the month include north-central Canada, most of Alaska — which had its third-warmest June on record — and the Western U.S., where about 80 percent of the region was in some stage of drought by the end of the month.

Much of northern and eastern Europe, western Russia, parts of Siberia, and north-central Australia also had warmer-than-average conditions, while western and southern Europe, Central Asia, and India had cooler-than-average conditions, NOAA reported.

According to NOAA, global land surface temperatures were the third-warmest on record, while ocean temperatures were closer to average, coming in as the 10th-warmest on record. An area of cooler-than-average waters in the eastern tropical Pacific may be acting to dampen global temperatures slightly, although NOAA experts said on Thursday that neither an El Niño nor a La Niña event is taking place, and one is not likely to take place through the fall. Such naturally occurring climate cycles can influence global weather and climate conditions, and can alter global average temperatures on shorter timescales than manmade carbon pollution, which studies have shown is most likely responsible for the long-term increase in global surface temperatures.

A recent report issued by the World Meteorological Organization found that nine of the 10 years between 2001-2010 were among the 10 warmest years on record for the globe, based on that organization's rankings, which can differ slightly from NOAA and NASA's rankings.  

In the U.S., June was yet another month of extremes, with a scorchingly hot and dry West contrasted with a record wet and relatively cool Midwest and East. In all, 18 states had a top 10 wettest June, with Delaware and New Jersey setting records for the wettest such month since record keeping began there in the late 19th century. Utah, on the other hand, set a record for its driest June, with a statewide average precipitation of barely a few drops — just 0.01 inches of rain.

The stark contrast in precipitation between the West and areas east of the Mississippi River has held true for much of 2013, with California having a record dry start to the year, while four states in the Midwest were record wet for the same period. California has had just 31 percent of its average precipitation for the year, said Jake Crouch, a climate expert at the National Climatic Data Center, on a conference call with reporters.

“We’re much below where we should be, and we’re much below the previous record Jan to June,” he said.

Comparing to the 20th century average is not really valid considering the first part of the 20th century was still recovering from the Little Ice Age.  It is a fact that warming is ongoing and we are warmer than a decade ago which was warmer than a decade before that.  However the rate of increase is slowing.  There is a lull in warming probably due to ENSO switching to more La Nina than El Nino.  The current slowdown in solar activity (since about 2008) has yet to be felt.  Likewise AMO has just started to go negative.

The bottom line is that the lull in warming is likely to continue and may even turn into global cooling.  How about we say that the warm streak is broken if we reach -0.3 here: The exception is if we get a large volcano which could cool us down to -0.5.

More bull from the experts as June here in Mass. was cooler than normal for most of the month and the months are getting colder and colder and the four seasons are just about history.  Let’s not forget about Alaska, which had snow in June, very unusual and all of the snow and ice that is not normally found in different parts of the world.  Al Gore and his global warming fiends (now called climate change, and of course the climate has been changing for the past 6000 years since the Great Flood) are getting richer and richer and dumber and dumber.  +JMJ+

Have you taken into consideration the chemical spraying that has been done around the world to control the weather?
In my opinion, this warming is due to a strategy performed by a billionaire who is pushing the global warming concept and will spend billions to convince us of this fairytale.  Our worst enemy is the government and its backers.

JMJ….it’s GLOBAL average temperature .... NOT the temperatures in your backyard.

Eric…the “little ice age” was a regional phenomenon, NOT a global one. The baseline being used is accurate when compared to temperatures from the last 800,000 years.

Jacqueline….you are too far gone. It’s people like you that make it clear that this problem is impossible to tackle. The human race is destroying the habitability of this planet. Thousands upon thousands of scientists are screaming at you about it but by the time it becomes undeniable, it will be irreversible.

Do you want your children living in that world?

The anti-science, anti-intellect, anti-reason, anti-expertise lunatics of global warming denial continue their tirade based on their upside-down world of misinformation, disinformation and false information!

Aside from the minimally deft attempts at spinning the data to adhere to the crumbling narrative, looking at the actual data in depth reveals quite a different reality than the author would prefer to admit but has no problem painting over or ignoring.

Five minutes of reality can be found in the following video.

We’re on the verge of a mini ice age as the effects of SC 21 and 22 ware off in favor of SC 23, which turned out to be 12.5 years long.  Current data indicates the Sun is losing it’s magnetic field at about 50 Gauss per year and it now appears by about the year 2020 there will not be enough magnetic filed on the Sun to generate sunspots.  The end result is SC 24 (the current one)could last as long as 18 years, which will result in accelerated cooling during the 2020s and beyond.  Note that none of the major news outlets talk about what is occurring on the Sun since it does not fit the agenda.  Already folks the Earth’s temperature has stabilized since about 2001 and I would expect a significant drop in those temperatures over the next 5-10 years, mainly due to the effects of the longer SC 23 and the current weak SC 24. Note what is happening in Europe with 3 out of the last 4 winters being severely cold in many areas.  Sea level is not rising, temperatures are not rising and the Sun is losing a lot of it’s warming power due to a lower solar irradiance associated with the upcoming weaker solar cycles.  We were very blessed during the 1980s and 1990s due to an active and giving Sun, but I’m afraid a major reversal is just around the corner.  As usual our world leaders have it completely backwards.  We should be preparing for colder days ahead, shorter growing seasons and less food production.  I truly hope they are right and warmer weather is ahead, but I’m afraid not if you just look at the facts.  You know the old saying “don’t confuse me with the facts”...They have too much money to make!

I like the June global temperature anomaly image, do you have this also available with proper temperature units (i.e. °C) ?  Hardly anyone in the world uses °F.

Thanks, Bernd

Actually the term “climate change” or “climatic change” was used before the term “global warming”,and both have been used by climatologists for decades. They refer to different aspects of climate. The fact is that global average temperatures are increasing,and have been for over a century. This is global warming,which leads to more weather instability such as more frequent and more violent storms,more frequent extreme droughts,etc.,which is climate change.

I doubt it Bernd. Your point is well taken though. It can also be seriously confusing when reports use the word degrees without specifying the unit. That happens all too often here. Personally I actually prefer Fahrenheit for the weather because there is more resolution. Also mid 30’s just doesn’t have the same ring to it as mid 90’s, which is where the temperature has been all week here in NJ – and of course getting to 100F and above doesn’t have that same heroic, three digit impact when converted to centigrade, when it’s only getting close or into the 40’s. I guess it’s what you get used to. Of course over there you do still get an imperial, i.e. 20 oz pint of beer at the pub.. right? I imagine there might be an uprising if that tradition got changed to half a liter.

Jacqueline, there are no “opinions” in science, only facts.

Sorry Fred Schmude,but the facts that are on the money are:
Global average surface temperature continue to rise [only the rate of increase is in question];
Global Ocean temperatures are rising sharply down to 2000 metres [the limit of our reliable measuring capacity];
Every Ice Sheet on the planet is losing volume at an accelerating rate; sea levels are rising at 3mm per year.
What you say about the Sun is largely true, it is, after all, one of the things most extensively studied by Climate Scientists, but the variation between Max. solar insolation and min. solar insolation has been extensivelyresearched and is [to take the very top estimate] only 30% of the measured planetary atmospheric energy imbalance - the rest, 70%+, is the GHGs.
So, I can imagine that in Texas you are longing for cooler weather but the overwhelming odds say…move North!

Dee, the Little Ice Age was certainly global.  It has been argued that the Medieval Warm Period was regional, basically Europe and Greenland.  That is debatable.  But there is no debate that the Little Ice Age resulted in famine in Europe, Asia and America.  The temperatures “from the last 800,000 years” have nothing to do with this article.
