Mankind Is the Main Cause of Global Warming

To save on space I will summerize my opponents arguments1. The sun is warming since other planets are warming.2. The sun via cosmic rays are causing global warming.3. Oceans are causing global warming.4. We’re going though a 1500-Year Cycle4a. The Medieval Warm Period5. Temperature of 1895-1946 vs 1957-20081. The sun is warming since other planets are warming.The sun isn’t warming at all, in fact it’s cooling. A study by Usoskin in 2005 debunks the claim that the Earth is warming due to a warming sun. He writes "...during these last 30 years the solar total irradiance, solar UV irradiance and cosmic ray flux has not shown any significant secular trend, so that at least this most recent warming episode must have another source." [1]In fact, the sun has been contributing to some cooling in the past few decades. [2]Other studies have also debunked the claimA study by Erlykin says“We deduce that the maximum recent increase in the mean surface temperature of the Earth which can be ascribed to solar activity is 14% of the observed global warming." [3]"Although solar and volcanic effects appear to dominate most of the slow climate variations within the past thousand years, the impacts of greenhouse gases have dominated since the second half of the last century." -Ammann [4]"The variations measured from spacecraft since 1978 are too small to have contributed appreciably to accelerated global warming over the past 30 years."- Foukal [5]So what about the other planets? First off Con commits the fallacy of composition, his reasoning is “if 1 planet is warming naturally all planets are warming naturally”. You must agree other planets are very different from Earth.Mars: Observations show Mars is experiancing short term regional warming, but not long term global warming. [6]Pluto: MIT scientists explain “Pluto’s orbit is much more elliptical than that of the other planets, and its rotational axis is tipped by a large angle relative to its orbit. Both factors could contribute to drastic seasonal changes.” [7]Jupiter: Global warming isn’t happening on Jupiter, it’s predicted. It's said to warm not because of the sun, but because “the loss of these atmospheric whirlpools, the average temperature on Jupiter will change by as much as 10 degrees Celsius, getting warmer near the equator and cooler at the poles," [8]Neptune: Neptune is warming. Its orbit is 164 years, our observations are less than a third of Neptune's year. The climate modeling of Neptune says Neptune is undergoing a seasonal change into summer. [9]This also would cause Triton's atmosphere to become thinner, causing warming. [10]2. The sun via cosmic rays are causing global warming.Looking at the data disproves this hypothesis. While cosmic rays are high the temperature is also high. Annual average GCR counts per minute (blue - note that numbers decrease going up the left vertical axis, because lower GCRs should mean higher temperatures) vs. annual average global surface temperature (red, right vertical axis)From NOAA [11], The Neutron Monitor Database [12], and Skeptical Science [13]"between 1970 and 1985 the cosmic ray flux, although still behaving similarly to the temperature, in fact lags it and cannot be the cause of its rise. Thus changes in the cosmic ray flux cannot be responsible for more than 15% of the temperature increase"- Krivova [14]"galactic cosmic rays appear to play a minor role for atmospheric aerosol formation events, and so for the connected aerosol-climate effects as well."- Kulmalahttp://www.atmos-chem-phys.net...Correlations between low clouds and cosmic rays broke in 1991, then cloud cover began to lag cosmic rays by 6 months [15] ,even though cloud formation should happen within a few days [16]Svensmark said the loss of correlation was because of long term calibration drift in ISCCP satellites, but the ISCCP themselves disagreehttp://www.realclimate.org...Sloan and Wolfendale pointed out Chernobyl disaster should've produced increased cloud cover according to this hypothesis, but there was nonehttp://arxiv.org..."In this chamber, 63 CERN scientists from 17 European and American institutes have done what global warming doomsayers said could never be done — demonstrate that cosmic rays promote the formation of molecules that in Earth’s atmosphere can grow and seed clouds,”This was based off a false understanding of the CERN paperSee the first video.http://www.youtube.com...3. Oceans are causing global warming.The oceans would cool when its heat goes to the atmosphere. Observations show oceans are warming [17]. The oceans are actually good evidence for the resolution."the observed ocean heat-content changes are consistent with those expected from anthropogenic forcing, which broadens the basis for claims that an anthropogenic signal has been detected in the global climate system." [18]4. 1500-Year CycleCon makes another category error here. There’s defiantly a 1500 year climate cycle. We know that from ice core data from Greenland -as Con cited-, but these events known as the “Dansgaard-Oeschger events” don’t increase the global temperature. It’s only a temperature shift or a see-saw temperature change in the 2 hemispheres. [19]Also see the second video.http://www.youtube.com...4a. The Medieval Warm PeriodCon cites the Medieval Warm Period to try and prove his claim about the 1500 year cycle. However there’s no evidence that shows the MWP was as warm globally as it is today.NOAA says“In summary, it appears that the late 20th and early 21st centuries are likely the warmest period the Earth has seen in at least 1200 years.” [20]and“The idea of a global or hemispheric "Medieval Warm Period" that was warmer than today however, has turned out to be incorrect.” [21]Here’s the differences 5. Temperature of 1895-1946 vs 1957-2008At the very end Con posts a chart of the temperature of 1895-1946 and 1957-2008. Both are very similar and seem to prove climate change is by nature. Based on data from Hadlet, GISS, NOAA, NCEP R1, NCEP TCR, ERA-40, and AMTI, Skeptical Science formed these 2 charts around those time periods. It’s close enough to see the claim is wrong [22]Back to ConSources in link below[1] http://tny.cz...
