    Climate is always changing. Half a degree C in more than 100 years doesn't worry me. Next 125 years may well show a down trend. Even if it goes up another half degree in a century, what goes up, eventually comes down again.

    Applied some common sense to that chart, though the data drawn may well be fudged. It's happened. :D

    In the scientific field of climate studies – which is informed by many different disciplines – the consensus is demonstrated by the number of scientists who have stopped arguing about what is causing climate change – and that’s nearly all of them. A survey of 928 peer-reviewed abstracts on the subject 'global climate change' published between 1993 and 2003 shows that not a single paper rejected the consensus position that global warming is man caused (Oreskes 2004).

    A follow-up study by the Skeptical Science team of over 12,000 peer-reviewed abstracts on the subjects of 'global warming' and 'global climate change' published between 1991 and 2011 found that of the papers taking a position on the cause of global warming, over 97% agreed that humans are causing it (Cook 2013). The scientific authors of the papers were also contacted and asked to rate their own papers, and again over 97% whose papers took a position on the cause said humans are causing global warming.

    The current warming trend is of particular significance because most of it is very likely human-induced and proceeding at a rate that is unprecedented in the past 1,300 years.1

    Earth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. This body of data, collected over many years, reveals the signals of a changing climate.

    The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century.2 Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many instruments flown by NASA. There is no question that increased levels of greenhouse gases must cause the Earth to warm in response.

    Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that the Earth’s climate responds to changes in greenhouse gas levels. They also show that in the past, large changes in climate have happened very quickly, geologically-speaking: in tens of years, not in millions or even thousands.3

    Your Meat-Eating Habit Is Killing More Than Just Cows

    http://www.motherjones.com/blue-marble/2015/08/your-meat-eating-habit-killing-more-just-cows

    The earth is in the middle of its sixth mass extinction, and die-offs are happening more quickly than ever before. In a little over a century, the world has said goodbye to more than 400 species—and many biologists believe this is just the beginning. Scientists predict that in the next 35 years, as many as 37 percent of the world's species could go extinct, if current trends continue.

    While we know that climate change is a major culprit in the loss of biodiversity, some researchers now believe burgers might also be to blame. In a new report, a team from Florida International University cited the land degradation, pollution, and deforestation caused by rising global demand for meat as "likely the leading cause of modern species extinctions," and the problem is only expected to get worse.
    Meat consumption has increased globally by 24 percent since the 1960s, mostly fueled by high demand from wealthy countries like the United States. Each year the number of livestock—specifically cattle, sheep, goats, and buffalo—increases by 25 million, requiring more space for both housing and feed production. Cattle, which require vast amounts of feed and produce the potent greenhouse gas methane, are expected to grow in number by more than 1 billion by 2050.

    The world's "biodiveristy hotspots," areas biologists have identified where many species flourish, have already been reduced by nearly 90 percent in size and are now restricted to only 2 percent of the Earth's land surface. What's worse is that these biodiverse areas are the places where meat production is most likely to increase in the coming years. Researchers have predicted an additional loss of as much as 50 percent of land to livestock production.

    Bobby Jindal, Louisiana governor
    Anthropogenic climate change: science inconclusive

    Bobby Jindal’s energy plan from September 2014 said the climate is perpetually changing and questioned the role humans play in it.

    The plan calls for strategies to mitigate “whatever climate changes may occur.” It also warns against “name-calling and grandstanding” when dealing with the issue while characterizing many liberals as intolerant, close-minded and arrogant.

    “Global warming has become a religion for many on the Left,” his plan reads. “For most radical environmentalists, their response to any questioning of their views on climate change is simply to yell ‘Heretic!’ This is not a logical, rational, or scientific way of approaching public policy.”

    I concur

    Eating Meat Is A Major Cause Of Global Warming

    http://planetearthherald.com/eating-meat-is-a-major-cause-of-global-warming/

    The United Nations’ Food and Agriculture Organizations have reported the meat industry is “one of the most significant contributors to today’s most serious environmental problems.” In Al Gore’s handbook, Live Earth, it says that not eating meat is the “single most effective thing you can do” to reduce your climate change impact.

    Methane is reported to be more destructive to the Earth’s climate than Carbon Dioxide or Nitrous Oxide. Methane is put out by billions of cattle, chickens and pigs which would be in much smaller numbers if humans were not raising them for consumption on “factory farms.” According to yesterday’s study, if even half the Earth’s population began eating vegan, then the global warming threat would go away.

    Methane has ten times the negative impact than Carbon Dioxide for the Earth, yet little attention is given to it.

    Al Gore

    Al Gore said Fl and new York would be under water in 2016. Im waiting.. Al Gore is a nut case.He also said there would be no ice at the north pole in 2015... IT HAS INCREASED SINCE 2010 by 2/3 rds. He make lots of money off this scare tatic... I think I will go have a STEAK... Eat a COW...:

    An Inconvenient Truth

    https://en.wikipedia.org/wiki/An_Inconvenient_Truth

    An Inconvenient Truth is a 2006 documentary film directed by Davis Guggenheim about former United States Vice President Al Gore's campaign to educate citizens about global warming via a comprehensive slide show that, by his own estimate made in the film, he has given more than a thousand times.

    Premiering at the 2006 Sundance Film Festival and opening in New York City and Los Angeles on May 24, 2006, the documentary was a critical and box-office success, winning two Academy Awards for Best Documentary Feature and Best Original Song.[4] The film grossed $24 million in the U.S. and $26 million in the foreign box office, becoming the tenth highest grossing documentary film to date in the United States.[5]

    The idea to document his efforts came from producer Laurie David who saw his presentation at a town-hall meeting on global warming which coincided with the opening of The Day After Tomorrow. Laurie David was so inspired by Gore's slide show that she, with producer Lawrence Bender, met with Guggenheim to adapt the presentation into a film.

    Since the film's release, An Inconvenient Truth has been credited for raising international public awareness of climate change and reenergizing the environmental movement. The documentary has also been included in science curricula in schools around the world, which has spurred some controversy.


    The film received a positive reaction from film critics. It garnered a "certified fresh" 93% rating at Rotten Tomatoes. At Metacritic, which assigns a weighted average score out of 100 to reviews from mainstream critics, the film has received an average score of 75, based on 32 reviews.[55] Film critics Roger Ebert and Richard Roeper gave the film "two thumbs up". Ebert said, "In 39 years, I have never written these words in a movie review, but here they are: You owe it to yourself to see this film. If you do not, and you have grandchildren, you should explain to them why you decided not to,"[56] calling the film "horrifying, enthralling and [having] the potential, I believe, to actually change public policy and begin a process which could save the Earth."[9]

    New York Magazine critic David Edelstein called the film "One of the most realistic documentaries I've ever seen—and, dry as it is, one of the most devastating in its implications."[57] The New Yorker's David Remnick added that while it was "not the most entertaining film of the year...it might be the most important" and a "brilliantly lucid, often riveting attempt to warn Americans off our hellbent path to global suicide."[58] New York Times reviewer A.O. Scott thought the film was "edited crisply enough to keep it from feeling like 90 minutes of C-SPAN and shaped to give Mr. Gore's argument a real sense of drama," and "as unsettling as it can be," Scott continued, "it is also intellectually exhilarating, and, like any good piece of pedagogy, whets the appetite for further study."[59] Bright Lights Film Journal critic Jayson Harsin declared the film's aesthetic qualities groundbreaking, as a new genre of slideshow film.[60] NASA climatologist James Hansen described the film as powerful, complemented by detail in the book. Hansen said that "Gore has put together a coherent account of a complex topic that Americans desperately need to understand. The story is scientifically accurate and yet should be understandable to the public, a public that is less and less drawn to science." He added that with An Inconvenient Truth, "Al Gore may have done for global warming what Silent Spring did for pesticides. He will be attacked, but the public will have the information needed to distinguish our long-term well-being from short-term special interests."[61]

    In "extensive exit polling" of An Inconvenient Truth in "conservative suburban markets like Plano and Irvine (Orange County), as well as Dallas and Long Island", 92 percent rated "Truth" highly and 87 percent of the respondents said they'd recommend the film to a friend.[62] University of Washington professor Michele Poff argued that Gore was successful in communicating to conservative-leaning audiences by framing the climate crisis as apolitical.[63] "Gore’s and the environment’s identification with the Democratic Party posed a significant challenge to reaching Republicans and conservatives, as well as those disgruntled with politics in general," Poff wrote. "To appeal to such individuals, Gore framed the matter as distinctly apolitical — as an issue both outside politics and one that was crucial regardless of one’s ideological leanings. These explicit attempts to frame the issue as apolitical take on further gravitas when we consider how Gore infused the film with reflections of conservative values. Indeed, Gore reached deeply into the value structure of American conservatives to highlight ideals that suggested his cause was not liberal, but rather was beyond politics, beyond ideology."[63]

    1,800 years of global ocean cooling halted by global warming

    http://www.sciencedaily.com/releases/2015/08/150817132013.htm

    An international team of researchers reported these findings in the August 17, 2015 issue of the journal Nature Geoscience. The study also indicates that the coolest temperatures occurred during the Little Ice Age--a period that spanned the 16th through 18th centuries and was known for cooler average temperatures over land.

    The concurrence of cooling events on both land and sea suggests that a global cooling phenomenon was erased by subsequent human-caused global warming.

    "Today, the Earth is warming about 20 times faster than it cooled during the past 1,800 years," said Michael Evans, second author of the study and an associate professor in the University of Maryland's Department of Geology and Earth System Science Interdisciplinary Center (ESSIC). "This study truly highlights the profound effects we are having on our climate today."

    Understanding how forcing factors changed ocean temperatures in the past can open a window into future climate change.

    "Model simulations by others have shown us that the oceans can impart a substantial delay in the warming of the surface climate," said Evans, who is also the lead of the Ocean2k working group of the Past Global Changes (PAGES) program. "With much of the heat from global warming entering our oceans, recent ocean surface warming may foreshadow additional future warming, in the same way ocean cooling appeared as a long-term response to large and frequent volcanic events in recent centuries."

    "We are still learning how the oceans mediate climate variations," Evans added. "Further work combining both observations and simulations of ocean climate will refine our understanding of the ocean's role in climate change."

    In other words we don't understand climate change or the forces affecting it except we are positive it's man kinds fault.

    That is clearly a belief rather than science. The science says we don't know don't understand and need to study more.
    Obviously the science is not settled.
    Those who claim it IS settled have zero credibility in anything they say.
    Because their mind is closed to any information that refutes their belief system.
