Not 97% but .3% of Climatologists agree.

Review finds the Medieval Warm Period was global & generally warmer than the present
http://www.climatedepot.com/2013/07...ly-warmer-than-the-present-when-co2-was-safe/

Climate alarmists claim that rising atmospheric CO2 concentrations due to the burning of fossil fuels – such as coal, gas and oil – have raised global air temperatures to their highest level in the past one to two millennia. And, therefore, investigating the possibility of the existence of a period of equal or greater global warmth within the past one to two thousand years has become a high-priority enterprise; for if such a period could be shown to have existed at times when the atmosphere’s CO2 concentration was far less than it is today, there would be no compelling reason to attribute the warmth of our day to the CO2 released to the air by mankind’s burning of the fossil fuels that supplied the power that sustained the Industrial Revolution. Therefore, in this review of the pertinent scientific literature, results of the search for such knowledge are presented for studies conducted within North American countries located south of the southern border of the United States.Focusing on the North American countries located south of the United States southern border, the studies herein reviewed clearly demonstrate the existence of a Medieval Warm Period far removed from the stomping grounds of the Nordic Vikings, while simultaneously helping to debunk the climate-alarmist claim that the MWP was a minor non-global phenomenon. Quite to the contrary, the MWP was truly global in extent, as demonstrated by data obtained on all of earth’s continents; and it was characterized by temperatures that were generally higher than those of the recent past and present. And it did so in an atmosphere with a CO2 concentration on the order of only 285 ppm, as compared to the 400 ppm of today.

Good work? LOL! drownpruf only demonstrated himself to be a global warming alarmist turd blossom.

 

Someone in the comments mentioned this is how the nutters start coming back into alignment with real science.

They first say natural changes from the Sun are happening but the impact will not be as strong as CO2. Slowly they will start to admit co2 is actually not such a big forcing on temps.

Which may also explain the study I read today saying the nutters are concerned about other gases and the ozone now.

Anything to keep the govt funding rolling in.

Sun’s energy output may have led to marked natural climate change in Europe over the last 1000 years

Sun’s energy influences 1,000 years of natural climate variability in North Atlantic

Changes in the sun’s energy output may have led to marked natural climate change in Europe over the last 1000 years, according to researchers at Cardiff University.


Scientists studied seafloor sediments to determine how the temperature of the North Atlantic and its localised atmospheric circulation had altered. Warm surface waters flowing across the North Atlantic, an extension of the Gulf Stream, and warm westerly winds are responsible for the relatively mild climate of Europe, especially in winter. Slight changes in the transport of heat associated with these systems can led to regional climate variability, and the study findings matched historic accounts of climate change, including the notoriously severe winters of the 16th and 18th centuries which pre-date global industrialisation.

The study found that changes in the Sun’s activity can have a considerable impact on the ocean-atmospheric dynamics in the North Atlantic, with potential effects on regional climate.

Predictions suggest a prolonged period of low sun activity over the next few decades, but any associated natural temperature changes will be much smaller than those created by human carbon dioxide emissions, say researchers.

The study, led by Cardiff University scientists, in collaboration with colleagues at the University of Bern, is published today in the journal Nature Geoscience.

Dr Paola Moffa-Sanchez, lead author from Cardiff University School of Earth and Ocean Sciences, explained: “We used seafloor sediments taken from south of Iceland to study changes in the warm surface ocean current. This was done by analysing the chemical composition of fossilised microorganisms that had once lived in the surface of the ocean. These measurements were then used to reconstruct the seawater temperature and the salinity of this key ocean current over the past 1000 years.”

The results of these analyses revealed large and abrupt temperature and salinity changes in the north-flowing warm current on time-scales of several decades to centuries. Cold ocean conditions were found to match periods of low solar energy output, corresponding to intervals of low sunspot activity observed on the surface of the sun. Using a physics-based climate model, the authors were able to test the response of the ocean to changes in the solar output and found similar results to the data.

“By using the climate model it was also possible to explore how the changes in solar output affected the surface circulation of the Atlantic Ocean,” said Prof Ian Hall, a co-author of the study. “The circulation of the surface of the Atlantic Ocean is typically tightly linked to changes in the wind patterns. Analysis of the atmosphere component in the climate model revealed that during periods of solar minima there was a high-pressure system located west of the British Isles. This feature is often referred to as atmospheric blocking, and it is called this because it blocks the warm westerly winds diverting them and allowing cold Arctic air to flow south bringing harsh winters to Europe, such as those recently experienced in 2010 and 2013.”

Meteorological studies have previously found similar effects of solar variability on the strength and duration of atmospheric winter blockings over the last 50 years, and although the exact nature of this relationship is not yet clear, it is thought to be due to complex processes happening in the upper layers of the atmosphere known as the stratosphere.

Dr Paola Moffa-Sanchez added: “In this study we show that this relationship is also at play on longer time-scales and the large ocean changes, recorded in the microfossils, may have helped sustain this atmospheric pattern. Indeed we propose that this combined ocean-atmospheric response to solar output minima may help explain the notoriously severe winters experienced across Europe between the 16th and 18th centuries, so vividly depicted in many paintings, including those of the famous London Frost Fairs on the River Thames, but also leading to extensive crop failures and famine as corroborated in the record of wheat prices during these periods.”

The study concludes that although the temperature changes expected from future solar activity are much smaller than the warming from human carbon dioxide emissions, regional climate variability associated with the effects of solar output on the ocean and atmosphere should be taken into account when making future climate projections.

 

The nation seems to be passing through a period in which too many U.S. Senators have been elected without so much as a high school level understanding of what drives the Earth’s climate and it isn’t the 0.038% of carbon dioxide (CO2) in the atmosphere.

On Monday, March 10, some twenty of them will stay up overnight on the Senate floor, according to The Hill, “to bring attention to the impacts of climate change.” You don’t get more idiotic than that. Climate, measured in decades and centuries, is always in a state of change. Meanwhile, the weather anywhere in the nation, determined by the changing seasons and responsive only to short-range forecasts, has turned colder thanks to a cooling cycle that is now into its 17th year.

Giving speeches all night in the Senate will not change that, but Sen. Sheldon Whitehouse (D-RI) has partnered with Sen. Barbara Boxer (D-CA) to announce a new “climate change caucus” when you can ask any of the million unemployed Americans what the Senate’s real priority should be.

Sen. Whitehouse seems to think that a winter storm that causes “little summer cottages (to be) washed into the sea” makes the non-existent issue of climate change “a bit personal.” Does this moron take rain or snow storms personally? When the sun rises in the morning, does he think it does so just for him?

Democrats are so afraid of the political fallout from the devastation of Obamacare and the lies told to support it that they are desperate to divert voter’s attention to anything else and climate change rates higher than having to discuss why we are still in a major recession after one full term by President Obama and the first year of his second. So, between now and the midterm elections in November, they will engage in all manner of theatrics to stay in office...

Obama Wasted $120 Billion on Global Warming in the last five years

you must be one of those guys who confuses a fraudulent consensus for science.
let us know when you have proof man made co2 causes warming in our current environment.

or

How about some proof man made co2 leads change in temperature instead of trailing it.
You see the chart below shows co2 trails change in ocean temp by a year and land temps by about 9 months.

I will also post this response on this thread.
