Climate Change Has Occurred Longer Than Reported, Study Says


Recommended Posts

A new paper is challenging our understanding of how long human-caused climate change has been at work on Earth. And the authors say their findings may question existing ideas about how sensitive the planet is to greenhouse gas emissions with potentially big implications for our global climate policy.

 

The new study, just out on Wednesday in the journal Nature, suggests human-caused, or anthropogenic, climate change has been going on for decades longer than existing temperature records indicate. Using paleoclimate records from the past 500 years, the researchers show that sustained warming began to occur in both the tropical oceans and the Northern Hemisphere land masses as far back as the 1830s and theyre saying industrial-era greenhouse gas emissions were the cause, even back then.

Where ya been, it's been constantly changing since day one.

 

'The team’s reconstructions indicated that significant and sustained warming began in the tropical oceans around the 1830s, about the same time it began over the continental land masses in the Northern Hemisphere. Warming in the Southern Hemisphere was delayed until about 50 years later, the reconstructions suggested — this likely has to do with differences in oceanic and atmospheric circulation there, Abram said.'..

 

or at least since 1830.

#1 In 2008, Al Gore boldly declared to a German audience that “the entire North ‘polarized’ cap will disappear in 5 years.” (Needless to say, that did not happen. In fact, the ice cap in the Arctic actually got larger this year.)

More and more data keeps getting released that not only confirms global warming is occurring but it's been happening longer than the experts thought.

Now look who has been heading science committees in our government.... Global warming denier republicans.

Just another reason why the Dems need to take back the Senate & the House and use science as a guide to create policy instead of oil companies.

Liar.

 

The National Sea & Ice Data Center dumps you in the melting ice.

 

Late summer in the Arctic, sea ice melt continues

August 16, 2016

As of August 14, Arctic sea ice extent is tracking third lowest in the satellite record. The southern route through the Northwest Passage appears to be largely free of ice.

As we all desperately attempt to stay warm, here are 10 of Al Gore’s more outlandish global warming quotes:

#1 In 2008, Al Gore boldly declared to a German audience that “the entire North ‘polarized’ cap will disappear in 5 years.” (Needless to say, that did not happen. In fact, the ice cap in the Arctic actually got larger this year.)

#2 “CO2 is the exhaling breath of our civilization, literally. … Changing that pattern requires a scope, a scale, a speed of change that is beyond what we have done in the past.” (Actually, without carbon dioxide life on earth would not exist.)

#3 “The planet has a fever. If your baby has a fever, you go to the doctor. If the doctor says you need to intervene here, you don’t say, ‘Well, I read a science fiction novel that told me it’s not a problem.’ If the crib’s on fire, you don’t speculate that the baby is flame retardant. You take action.”


#4 During a speech at NYU Law School in 2006, Al Gore made the following statement: “Many scientists are now warning that we are moving closer to several “tipping points” that could — within as little as 10 years — make it impossible for us to avoid irretrievable damage to the planet’s habitability for human civilization.”

#5 “Here is the truth: The Earth is round; Saddam Hussein did not attack us on 9/11; Elvis is dead; Obama was born in the United States; and the climate crisis is real.”

#6 “The interior of the earth is extremely hot – several million degrees.” (It actually peaks out at about 11,000 degrees.)

#7 “There is an air of unreality in debating these arcane points when the world is changing in such dramatic ways right in front of our eyes because of global warming.”

#8 “It would be an enormous relief if the recent attacks on the science of global warming actually indicated that we do not face an unimaginable calamity requiring large-scale, preventive measures to protect human civilization as we know it.”

#9 “The survival of the United States of America as we know it is at risk. And even more — if more should be required — the future of human civilization is at stake.”

#10 “We ought to approach this challenge [of global warming] with a sense of profound joy and gratitude: that we are the generation about which, a thousand years from now, philharmonic orchestras and poets and singers will celebrate by saying, they were the ones that found it within themselves to solve this crisis and lay the basis for a bright and optimistic human future.”

In other words...

 

Just lie

 

 

Quote by Al Gore, former U.S. vice president, and large CO2 producer: "I believe it is appropriate to have an over-representation of factual presentations on how dangerous it is, as a predicate for opening up the audience to listen to what the solutions are, and how hopeful it is that we are going to solve this crisis."

Exactly what you did.

This is so funny... Science keeps updating their data proving wing nut nation wrong and all they can do is deflect to Al Gore.

 

 

 

The National Sea And Ice Data Center:.

 

Ice loss has progressed quite rapidly in the Beaufort and Chukchi seas, where broken up ice floes are starting to melt away. However, large, thick multiyear ice floes persist in several areas; it remains to be seen if they will survive the melt season. A wedge of open water has also penetrated northward from the East Siberian Sea, yet ice remains extensive in the Laptev Sea, blocking the Northern Sea Route. Ice extent continues to be low in the Kara, Barents, and East Greenland seas. The southern (Amundsens) route through the Northwest Passage appears open in Advanced Scanning Microwave Radiometer 2 (AMSR2) data. However, data in visible wavelengths from the NASA Moderate Resolution Imaging Spectroradiometer (MODIS) instrument still show some ice.

would the study date Global Climate change back say 5 billion years linear expectations think it came from? Syllogism through and throughout.defending intellectual corruption eternally or until nobody minds it anymore and another invented possibility takes its place governing existential thought between divided potential differences of opinions while simultaneously spaced apart exponentially...

 

 

the lengths academia goes to protect artistic license.

ha ha ha ha ha.

Excellent OP.. We do need to burn fossil fuels for a few more decades but we should try to scrub the emissions as best we can

 

We have gotten very efficient and clean at burning hydrocarbons

And the only way we can move forward as a country is by electing presidents and representatives that respect science.

If we kept a GOP senate and House, we'd be doomed.

Agreed. Continue to develop new technologies and perfect existing ones.

Intellectual corruption is completely ruthless and anyone practicing the art cannot be instinctively honest at any time they exist adapting at the core of Eternity.eternally compounding details never matched again so far. Does however produce the illusion of linear time when channeling thoughts down literal paths of circle logic between every one trained to think out of the moment and everyone controlling the mental divisions composed by potential differences of opinions about what life could be figured outside natural displacement here.

Well you're half right.

We need to ween ourselves off global warming carbon emissions.

We'll NEVER do that under a republican government..

 

We will never consume less energy than we do now. So the alternative is to find another source (likely multiple sources) of energy. As new technologies come online, market forces will naturally replace fossil fuels. As that happens, technologies will make better, cleaner more efficient use of the fossil fuels we use now. That is already happening regardless of the White House occupant.

Translation: keep the current climate change deniers in government and doom the country and world.

There is no such thing as efficient use of fossil fuels. They create carbon emissions which creates global warming.

Bush set this country back 8 years in progress from weening ourselves off of carbon emissions.

It's tantamount who is in the WH and sets the course for the future.

You just don't have the balls to admit it Mr. Republican.

About the 1,000,000 th time Ive called you out on your right wing bias.

Soulless Result is nothing but white noise.

Sole result is a physical absolute your ideology promises doesn't exist in plain sight. Soulless Result is a gender that doesn't play a social role in defending intellectual corruption cradle to grave.

Soulless Result is now referring to himself in the 3rd person.

 

Hilarious.

Oh, me, myself, and I aren't three projections of this sole result via vocabulary and common verbal lines of communicating ideas between sole brains occupying the same moment?

 

Try again denier life originated at the core of Eternity and extinction will arrive at the same place.

 

why is symbolism priceless and specific genetic displacement worth less socially in your world? What do you not want loyalists of ideology to recognize honestly among those of sharing your mind?

 

the absolute corruption of a royal "we" your I gets to direct with policy after your death. Vanity comes when one believes they can live beyond the moment here. May the hell you mentally inflict on everyone else be yours until your last breath.

 

Eternity begins now and eternal life ends here specifically as alive.

 

Don't like it, stop breathing permanently. Until then, some one in society knows what you aren't telling your loyal subjects of interpretation between alpha, Beta, and omega mankind being they, them, and those casted as people historically and current nation building and social reconstruction of passed societal interpretations..

 

Silence doesn't mean tolerance anymore than riots seek freedom from self contained to their own skin.

The troll Zero's usual lies and distortions...

 

In the real world....

 

Former Vice President Gore DID NOT SAY THAT!

 

That is a lie and a part of a fossil fuel industry propaganda meme.

 

What he actually said was this:

 

"Last September 21 (2007), as the Northern Hemisphere tilted away from the sun, scientists reported with unprecedented distress that the North Polar ice cap is "falling off a cliff." One study estimated that it could be completely gone during summer in less than 22 years. Another new study, to be presented by U.S. Navy researchers later this week, warns it could happen in as little as 7 years."

 

The head U.S. Navy researcher he was referring to, Professor Wieslaw Maslowski, said this:

 

"Given the estimated trend and the volume estimate for OctoberNovember of 2007 at less than 9,000 km3, one can project that at this rate it would take only 9 more years or until 2016 ± 3 years to reach a nearly ice-free Arctic Ocean in summer. Regardless of high uncertainty associated with such an estimate, it does provide a lower bound of the time range for projections of seasonal sea ice cover."

 

So...the prediction was for an ice free summertime Arctic sometime between 2013 and 2019.....NOT "I predict the ice caps will melts by 2013"...

 

And that twaddle about Arctic ice "getting larger"... that is another lie and part of another deliberately concocted fraudulent denier cult myth about the actual state of the Arctic.

 

In the real world....

2015 in review

National Snow and Ice Data Center

January 5, 2016

(excerpts)

December ended with Arctic sea ice extent tracking between one and two standard deviations below average, as it did throughout the fall. This caps a year that saw the lowest sea ice maximum in February and the fourth lowest minimum in September. The first week of 2016 has seen very slow ice growth in the Arctic.

 

Sea ice extent for December 2015 averaged 12.3 million square kilometers (4.74 million square miles), the fourth lowest December extent in the satellite record. This is 780,000 square kilometers (301,000 square miles) below the 1981 to 2010 average for the month. The ice is currently tracking near two standard deviations below the 1981 to 2010 long-term average. Sea ice extent is well below average in the Bering, Okhotsk, and Barents seas.

 

A broad area of Europe and western Russia, including the northern Barents Sea, saw temperatures as much as 4 to 8 degrees Celsius (7 degrees to 14 degrees Fahrenheit) above average at the 925 hPa level. Conditions were also fairly warm over the central Arctic Ocean, north of the Canadian Arctic Archipelago.

 

Arctic sea ice extent averaged for December 2015 was the fourth lowest in the satellite record. Through 2015, the linear rate of decline for December extent is 3.4% per decade, or -44,200 square kilometers (-17,000 miles) per year.

 

Figure3.png

 

The year 2015 will be remembered for two major events in Arctic sea ice extent: the lowest Arctic maximum in the satellite record, and the fourth lowest Arctic minimum in the satellite record. The record-low Arctic maximum occurred on February 25, 2015 and was among the earliest seasonal maxima in the 37-year satellite record. The fourth lowest Arctic minimum occurred on September 11, 2015 and was likely a consequence of very warm conditions in July and an increasingly young and thin ice cover.

 

The satellite passive microwave record for sea ice now spans more than 37 years. As we have documented, clear downward trends characterize Arctic sea ice extent and concentration in all months. During the Arctic maximum, declines in extent and concentration are pronounced in the Barents Sea and Sea of Okhotsk, but ice cover has increased slightly in the Bering Sea. During the Arctic summer minimum, all areas show negative trends.

 

An exceptional weather event during the last days of the year brought a heat wave with surface air temperatures up to 23 degrees Celsius (50 degrees Fahrenheit) above average in the far north, and a brief period when surface temperatures at the North Pole approached or perhaps even exceeded the freezing mark. A temperature of +0.7 degrees Celsius was briefly recorded by a buoy weather station near the North Pole on December 30, 2015. The event was linked to the combination of a very strong low pressure system near Iceland and a somewhat less intense low pressure system located near the North Pole. This was associated with an amplified trough at 500 hPa over the northern North Atlantic and a pronounced ridge of high pressure at 500 hPa to the east over central Europe, extending into the Kara Sea. This created a strong, deep inflow of warm, moist air into the Arctic Oceans high latitudes. The low near Iceland strengthened rapidly in the last days of December, reaching a minimum pressure of 935 millibars, equivalent to a hurricane.
