Was last month warm where you live? If so, you weren’t alone. According measurements taken by the National Oceanic and Atmospheric Administration (NOAA) June 2010 was the hottest June on record worldwide. But this is not a new trend, at least for this year. March, April, and May 2010 were also the warmest on record. This was also the 304th consecutive month with a global temperature above the 20th century average. The last month with below-average temperature was February 1985.

Here are some of the numbers:

* The combined global land and ocean average surface temperature for June 2010 was the warmest on record at 16.2°C (61.1°F), which is 0.68°C (1.22°F) above the 20th century average of 15.5°C (59.9°F). The previous record for June was set in 2005.

* The June worldwide averaged land surface temperature was 1.07°C (1.93°F) above the 20th century average of 13.3°C (55.9°F)—the warmest on record.

* It was the warmest April–June (three-month period) on record for the global land and ocean temperature and the land-only temperature. The three-month period was the second warmest for the world’s oceans, behind 1998.

* It was the warmest June and April–June on record for the Northern Hemisphere as a whole and all land areas of the Northern Hemisphere.

* It was the warmest January–June on record for the global land and ocean temperature. The worldwide land on average had its second warmest January–June, behind 2007. The worldwide averaged ocean temperature was the second warmest January–June, behind 1998.

* Sea surface temperature (SST) anomalies in the central and eastern equatorial Pacific Ocean continued to decrease during June 2010. According to NOAA’s Climate Prediction Center, La Niña conditions are likely to develop during the Northern Hemisphere summer 2010.

Some regions on the planet, however, had cool temps for a northern hemisphere summer. Spain had its coolest June temperatures since 1997, and Guizhou in southern China had its coolest June since their records began in 1951.

Still, with those cool temperatures, the planet on the whole was warmer.

Arctic sea ice extent for June 2010 was 10.87 million square kilometers (4.20 million square miles). Credit: NSIDC

Other satellite data from the US National Snow and Ice Data Center in Colorado shows that the extent of sea ice in the Arctic was at its lowest for any June since satellite records started in 1979. The ice cover on Arctic Ocean grows each winter and shrinks in summer, reaching its annual low point in September. The monthly average for June 2010 was 10.87 km sq. The ice was declining an average of 88,000 sq km per day in June. This rate of decline is the fastest measured for June.

During June, ice extent was below average everywhere except in the East Greenland Sea, where it was near average.

As the Arctic permafrost continues to melt and release gigatons of Methane trapped below that ancient layer, Global Warming and ‘odd’ weather conditions will no doubt accelerate. Methane is 20X worse (stronger) than CO2 as a greenhouse gas.

Should deep ocean waters continue to warm, there is a very real possibility that multi-gigatons of frozen Methane Hydrates will melt and also be released into the atmosphere. Of course this is the worst case scenario.. but never-the-less more a possibility today than ever!

Oops…. not 20X worse… more like 10X~

That is a dangerous word the article used. “anomaly” Conspiracy theorists love that word.

Hydrate and permafrost melt is the big problem we face. If this releases enough methane it will run away on us. We are in a lot of trouble, for it is hard to see how we can really make reductions in CO_2 output fast enough to prevent this from taking place.

I expect the righwing types to be all over this site with their nonsense pretty quickly.

That is a dangerous word the article used. “anomaly” And yet it is a stock word for Earth sciences, such as in the South Atlantic Anomaly, which is a Van Allen belt minimum height, and the North Atlantic Oscillation, which “is characterized by pressure anomalies of one sign in the Arctic with the opposite anomalies centered about 37-45N [Wikipedia]” Though here I think it is extremes. And it is amazing how AGW attribution science has strengthened since IPCC 4 (-07). This year a paper came out showing precisely that such extremes, among other weather characteristics down to continental scales or smaller, nowadays can be attributed consistently (i.e. with all natural sized parameters) and robustly (now with 2 sigma… Read more »

The recent ‘Deep Horizon’ oil well explosion in the Gulf, may have been the result of puncturing a large pocket of Methane Hydrate. The subsequent rapid gas expansion due to contact with a relatively warm drill string and ‘drilling mud’ may have been the ‘trigger’? Released explosive gases then traveled up the drill string and with a simple spark – KAHBOOM!

Evidence of massive underwater landslides in the Atlantic, off the continental shelf of the East Coast, are theorized to have been caused by sea level retreat during the last Ice Age exposing Methane Hydrate layers to warmer waters. Bubble bubble, toil and trouble..

I’m not a science guy like many of the other readers here, and I don’t care to take sides on the climate change debate. All I know is what I’ve experienced over the years here in Canada. It seems as each year goes by, it gets hotter overall. Even factoring in for how memory plays tricks on us as time goes by, It feels hotter – a lot hotter! Last winter was more like an extended fall. Temperatures rarely dived below zero. There were a couple days in December to February where I WALKED OUTSIDE IN SHORTS. If you know anything about Canadian winters, this is unheard of – yet there I was.I understand that these may have… Read more »

OMG where are you living? May 2010 was so cold and rainy all across the Europe that I tought the summer would never come again! Finally we have a little bit warmer month…

To Aqua. There is no evidence that the Gulf of Mexico spill is anything other than an accident due to poor maintenance. The Gulf experiences seepage from oil deposits close to the sea bed. This happens ALL over the world. In fact it was this is how oil was ‘discovered in Persia just over a hundred years ago. The ocean landslides generally occur in the deep, cold areas and are far more likely to bury the hydrates than expose them to warmer water. The temperature of the ultra deep ocean doesn’t really change much whether we’re in a glacial or inter-glacial period. If I remember correctly the global temperature has to rise to around 10-15 degrees higher than… Read more »

Aqua, as Paul Eaton-Jones says.

There was a dumb internet wave with that theme a few days back, and skeptics as well as overs had a good laugh and a sound head shake over the antics.

Remember: hoof beats; think horses, not zebras.

When Frozen Methane starts to melt, you know what we need to do right? Let it burn baby burn!

Did they publish their exact measuring points? With all the deceptive at best science and massive amounts of money in this debate I want more info these days to make my own conclusions.

I’m not so sure about this data. I remember much warmer temperatures in June when I was a kid. We often went over 100 F for days in a row, and we would go without rain for some time as well. This June, we haven’t gone over 100 F at all, and we’ve had above average rainfall. Also this spring was wetter and cooler than it has been in years. As for the winter… we had at least one inch of snow on the grown for over 4 months. Something which I never remember. That also means we were below freezing much of the time. Take this data as you will. Anyone who has taken advance probability courses… Read more »

To continue…
This doesn’t mean I don’t think there isn’t global warming… there is no doubt some parts are warmer than they have been for years. However, I think they are exagerating some areas which haven’t experienced warming.
They are saying my area has been warmer this year, when it really hasn’t.

@Paul Eaton-Jones and @Torbjorn Larsson OM: I suggest you look more ‘deeply’ into what evidence is out there. For example, take a closer look at the link I posted. http://marine.usgs.gov/fact-sheets/gas-hydrates/title.html As far as ‘no connection’ to the Deep Horizon’s penetrating a Methane Hydrate pocket… again, look a little deeper. “Survivors of the BP rig explosion told interviewers that right before the April 20 blast, workers had decreased the pressure in the drill column and applied heat to set the cement seal around the wellhead. Then a quickly expanding bubble of methane gas shot up the drill column before exploding on the platform on the ocean’s surface.” from: http://www.guardian.co.uk/environment/2010/may/20/deepwater-methane-hydrates-bp-gulf Or: http://www.youtube.com/watch?v=s0TZ7zgrn3k Please do a simple Google search with “Methane… Read more »

“I’m not so sure about this data. I remember much warmer temperatures in June when I was a kid.”

This is why science uses real measured data instead of memories.

I also remember warmer days, even colder days and wet days, and windy days and stormy days and snowy days. The human mind is easily tricked into ignoring the other parts that does not support their findings.

The question is how many days in a row did you remember being warm in a decade period of time?

Well we had over 17″ of snow (12″ one day) last winter in dallas Texas. That is quite an anomoly. Kids loved it.

To Aodhhan. Climate change doesn’t necessarily mean that everywhere gets hotter [or colder] at the same time. Any increase or decrease in temperature will initially affect wind/rain patterns resulting in more/less rain or snow at any given area. So you may well have seen more snow or cooler temperatures than you did a few years ago. That isn’t to say the climate isn’t changing and getting warmer.While the earth is waiting for temperatures to reach some kind of equilibrium there will be a temperature gradient causing stronger winds [ in effect]. Once the polar regions are free of ice and the difference in tepmeratures narrows winds drop to gentle breezes and rainfall is limited to coastal belts. This… Read more »

Paul…
I’m aware what it means. Apparently you didn’t read what I was saying.
I stated they are claiming data in my location which isn’t true. Reread… I stated I know some areas are warmer.
Many inidividuals tend to skew results a bit, since they don’t want to stop something they worked a long time at. “Border areas” are likely to be skewed in favor of the author. So basically, the blue areas probably should be a bit larger than shown.

Olaf…
Many days at a time. I remember one Summer where we had to limit the use of water. Playing ball on hard, dead, yellow grass isn’t a lot of fun.

I don’t consider myself Right Wing, but I do consider myself Conservative, and by that I mean we should conserve financially and environmentally. I do think the Earth is naturally warming, but I also believe we are adding to the effect. Greenhouse gases are a big problem, but I think the bigger threat is deforestation. Trees remove CO2 from the air and provide O2. Considering the amount of deforestation that has gone on all over the world, it’s no surprise CO2 levels are up. Add the additional CO2 and other greenhouse gases being dumped into the atmosphere, and we only make the problem worse. Honestly, I think the damage has already been done, and it’s too late to… Read more »
