Watch 62 Years of Global Warming in 13 Seconds

From our friends at NASA comes this amazing 13-second animation that depicts how temperatures around the globe have warmed since 1950. You’ll note an acceleration of the temperature trend in the late 1970s as greenhouse gas emissions from energy production increased worldwide and clean air laws reduced emissions of pollutants that had a cooling effect on the climate, and thus were masking some of the global warming signal.

The data come from NASA's Goddard Institute for Space Studies in New York (GISS), which monitors global surface temperatures. As NASA notes, “All 10 of the warmest years in the GISS analysis have occurred since 1998, continuing a trend of temperatures well above the mid-20th century average."

A global catastrophe powered by regular people doing regular things every day. I = P x A x T. Impact equals population times affluence times technology. Every day modern civilizations push as hard as they can to increase affluence (wealth) and technology. And population multiplies the effects.

We are doomed.  The human race will never come together in a significant enough way to offset what we are doing to the environment.  There will always be one group or another that will sabotage any chance to fix the issue for their short term political or monetary gain. 

Its just the way it is.

...Or this is the natural fluctuation of temperature and weather. There once was an ice age that man had nothing to do with.  There once were dinosaurs roaming around that man had nothing to do with.  Themps go up and down in a cycle and because of the advances in data collection and weather station changes it is impossible to say man has created climate change. It’s also impossible to extrapolate data and predict what the temp will be in 20 or 50 years.  NOAA and other weather predictors can not give an accurate 7 day forecast so why do people believe they can predict 10, 20 to 50 years from now? man made global warming is the biggest hoax ever played on the human race.

Even accounting for natural fluctuations, the current accelerating warming trend does correlate with human greenhouse gas production.  Read the science, deniers.

I’m calling BS on that last sentence. Higher temperatures cannot secretly go on behind the scenes. Pollution laws caused less protection from the sun, period.

If the government(s) really cared about global warming, they would be building solar umbrellas. A shadow covering a measurable fraction of the Earth - say half a percent - would drop temperatures in a measurable way. It wouldn’t even have to be ONE umbrella, just a speckling of satellites. Hell, make them solar mirrors and they’ll self-propel. I’m an average citizen who thought of this decades ago, so why isn’t someone in power making them already?

One may be assured that fundamentalist Republicans - who know beyond fact - that even the suggestion of global warming is a liberal plot, are not on the readers list here.

The 20th century saw a period of warming.  Is this surprising?  No.  Is the cause well understood?  No.

Have there been periods of similar warming in the past as revealed by proxy data?  Yes.

One thing that is known, the 20th century had a warming trend of comparable magnitude early and late within the 20th century.

I could be wrong about this, but I thought the warmest decade of the 20th century was in the 1930s.  If that’s so, or even if the 1930s was the second warmest decade, how do you reconcile that with the fact that most of the stuff that we say is causing temperature rises hadn’t been generated at that point?

I don’t quite get it.  I remember 1977 being extremely hot - it was the Queen’s Silver Jubilee.  In ‘84 it was hot and in ‘99 too.  But I lived up in Scotland from 2000 until 2007 - and it was extremely cold - yet your projections show it to be hot.  Ugh?  Someone’s telling porkie pies here.  And as for now - I’m in Germany, it’s April and it’s bloody freezing!!!!!  Apparently the coldest March on record for a long time.  Perhaps now we’re heading for the big freeze of the ice age?

Where is the animation does the cause of warming appear?  Interesting data, but I think there’s something less scientific going on when we manufacture a causal relationship based simply on correlation.

Maybe they should explain global warming to Minnesota! It’s may, and it’s snowing out, and most of this week is forcast for high tempertures in the 40’s. Usually the ice is gone off the lakes by now, and people are still ice fishing!

OK, to all the people that think GLOBAL WARMING is the cause of humans get your heads out of your…...
Just after the Dark ages came the Renascence, you know the period of great art, advances in medicine and an increase in crop yields world wide including grapes being grown in England that produced a wine that was better than the wines from France. The last part of the sentence above is important here for one reason, that being, temperatures world wide where high enough to allow grapes to be grown in England, think about it people.

This is also information you can look up yourself, be smart and educate yourself and question everything being fed to you by those in power!

Looks like I’m the only one who noticed the fact that the change in temperature was a whole 3-4 degrees… many stupid comments.  Just wow.  Talking about remembering “real snow” from something that shows 3-4 degrees of difference… funny.

Quote by Club of Rome (research who it’s committee is made up of):

“In searching for a new enemy to unite us, we came up with the idea that pollution, the THREAT OF GLOBAL WARMING, water shortages, famine and the like would fit the bill….All these dangers are caused by human intervention….and thus the “real enemy, then, is humanity itself….believe humanity requires a common motivation, namely a common adversary in order to realize world government. It does not matter if this common enemy is “a real one or….one invented for the purpose.”

I am not making a statement at all about the truth of fallacy of man made global warming.  I am only going to make 1 observation…..The Viking civilization on Greenland was abandoned because the area they were living in became too cold and snow covered to eek out a living.  That same area is beginning to melt out and become arable again.  So in my mind, before 5 hundred years ago the temperatures in Iceland must have been somewhat close to what they are becoming now, maybe a little warmer…..what are people’s opinion of this??

By Carlos Osuna (Monterrey/NL/64660)

Sometimes it just amazes me how easily “scientific opinion” can be converted into “scientific fact”.

Stupid sounding statements like “clean air laws reduced emissions of pollutants that had a cooling effect on the climate” become easy ways for scientist to push their agendas.

Today, we fear climate change as much as we feared the Ozone hole in the 80’s.  We create models and make them fit our expectations and everybody’s “happy” that those models fit.

We forget that there’s more in play, than just CO2. We forget about the “Little Ice Age” between 1350 to about 1850 which of course, needs to be followed by an increase in temperature since the Earth needs to return to it’s real medium temperature. That is, we tend to set the “standard” temperature of the earth as that occurring during the XIX and XX century when it reality it was “way too cold” as it was just coming from the Ice Age.

Next we tend to forget the autoregulatory systems of earth, where increase sea levels, also increase Carbon Absorption, which in turn will decrease the temperature and return the Ice Caps.

In the end, this era had to had it’s “thing” and “Global Warming” is it and there’s no way we can convince everybody that this is a normal cycle and we need to stop wasting our time in “precise models” about nuances and start creating a better of the big picture and how we are only a small part of the equation although our hubris makes us think we are the ONLY PART of the equation.

Michael Chriton was going to write a book about the disaster of global warming.  After 3 years of independant, unbiased research he wrote a book called, “State of Fear.”  I know it is fiction but this was from a man who came into the project as a true believer and left more than skeptical.  He rightly said the biggest problem on BOTH sides is there IS a predetermined agenda.  He gave a University graduation speech that spoke to this and the need to stop agendas!  If scientists know who is funding them, THEY HAVE AN AGENDA.  It’s called, keep the money flowing and it STOPS TRUE RESEARCH.

@ dan in illinois - according to the NASA link in the article above, 1930 was cooler than most of the past 30 years. There is a fair amount of year-year fluctuation in temperature, but the increasing trend is fairly distinct in this figure[1]-670.jpg

What I’d like to know is what is the baseline for this animation? We see + and - changes, so what is the 0 point? The temperature in 1952?

Interesting.  Can you do the same thing for the past 100,000 years to see what has happened to the global climate and global warming and cooling during that time when there were minimal human influence on the earth?

By Christian

The earth is in a natural cycle, ice caps slowly melting because THATS WHAT HAPPENS. You have fresh water dumped in the ocean, changing salinity levels and changing ocean currents slowing down the transfer of heat to the north and once it gets cold enough we’ll have another ice age, it happened how many thousands of years ago where there were no f*** cars to begin with. No doubt we’re polluting, suffocating ourselves in our own atmosphere, but if you think cars and production are the only cause of these “climate change” and the ice caps melting, then you’re an ignorant fool.

I cannot beleve that we are still working on explaining the difference between local weather and global climate. Central Europe experienced an unusually cold April? No, actually it experienced a pretty normal April as far as temperature is concerned, as seen on a longterm scale, but we who live there are all so used to warm Aprils that it shocked us. However, even that doesn’t mean anything when talking about climate change. One cold April does not equate to a cold year. We are talking about averages - I believe mean averages - across the entire year, compared to averages across historical entire years. So our summer, autumn and end of year will decide whether this is a warm or cold year. Seeing as we are already hitting above 25 degrees celcius in the first week of May, and this will probably now keep until say October more or less, I am not worried that this year will buck the warming trend in any way.

By Paul Watkins (Melbourne/Victoria/3153)

So if other sources say the planet hasn’t warmed for the last 10 years, and part of the above the sentence saying “clean air laws reduced emissions of pollutants that had a cooling effect on the climate, and thus were masking some of the global warming signal” - how does a cooling effect mask a warming signal? That would be like saying a heating effect masks the global cooling signal!
What are we to believe when there were leaked emails from scientists presenting their theories at the Copenhagen Climate Change conference in 2009 showed that global warming was a scientific conspiracy, in which was alleged that scientists manipulated climate data and attempted to suppress critics. Well, thats one way to be funded to keep their jobs.
The climate goes in cycles as we all know, and scientific predictions have known to be incorrect before.
Thats not to say we stop scientific investigation of the climate. But lets get not jump to conclusions!

“Saunders said that in Illinois, mammoths typically seemed to have roamed glacial plains about 60 miles to the north of the swamps where the mastodons were living. He said both beasts died out — along with more than 30 other types of large mammals — during North America’s Great Extinction about 10,000 years ago.”

Sorry, I didn’t hear you, when was it that the heat started coming again?  This is about the M&M of Illinois, one site is twelve miles south of me, at a 180 heading..  Is that because it was much colder 10,000 years ago?  Yep, you got it, we live on a living, breathing earth..  Ask those caught in Earthquakes and Tsunamis if the earth has any power to change things..    I am glad I don’t live for 500 years, I would not get out alive anyway!

Global warming is a fact. That it is caused by man in any way is fiction. I read a report from NASA astronomers a few years ago that the sun and ALL OF THE PLANETS ARE WARMING AT THE SAME RATE due to a natural warming cycle of the sun.

Oddly enough,, around 1954-ish, I remember reading in My Weekly Reader that AN ICE AGE WAS COMING!  Since I was already finding it really hard living through Wisconsin’s endless winters and 3 ft+ snow falls with 6 + foot drifts, I was TERRIFIED at the time.  WHO KNEW that within my lifetime, that would be totally reversed.  The compression timing video is incredible. YOu can almost “feel the heat.”

Let’s look at more of the science of climate,shall we…Sunspots have a correlation to climate that is very well known and we are in a 50 year period of abnormally high solar activity.Check out the DeVries-Suess cycle.Polar icecore data correlates to world wide interglacial warm periods,i.e.greatly reduced icecaps,with no human intervention. C14 and Be10 levels are closely related to solar flux levels which drives global temperatures and are historical records good for 5750 years at least. A 1% change in cloudiness would account for all the measured increase but IPCC computers don’t do clouds. Demonising dissent hinders science.
