ORIGINAL: jlf1961 Okay, I will pose this question, Awareness. Increased solar activity also affects climate by causing warming, true? Just as decreased solar activity causes cooling. Now, for the last decade, solar activity has been significantly higher than average, and as a HAM radio operator, I have used this to talk very long distances, since the increased output of solar electromagnetic waves allow for the skipping of radio signals on the upper parts of the atmosphere. I did say that the last ten years have been the hottest on record. I did admit that the current ocean temps are also the hottest on record. I have stated on a number of occasions that something is going on with the climate, but, while some areas have set record high temps, others have set record low temps. My disagreement is with the idea that humans are solely responsible. As I stated in another thread. IF you were to take the total warming cooling cycle of the earth, set it to an average time for each cycle, the earth should be cooling. However, mother nature never follows a strict schedule. If she did, the Cascadia fault would have ruptured about 50 years ago, Yellowstone would have erupted 50000 years ago, and there would have been a catastrophic eruption of all the major Cascade volcanoes in the last hundred years or so. Hell, the Krakatoa eruption was large enough to throw the planet into a small ice age, and didnt. In fact, the five largest eruptions of the past 150 years have put enough aerosol compounds in the atmosphere to have cooled the average temperature of the planet considerably, including ones that did not happen in the 20th century. In point of fact, since the year without a summer (google it) the average temp planet wide has been slowly rising, along with the increased amount of sunspot activity over the duration of the eleven year cycle. And while we can take ice cores from Greenland and the south pole and get a good idea of the planet's climate for the last couple of hundred thousand years, they show that there have been periods where the cooling cycle has been delayed. However, there is no way to accurately look at the solar activity record for the same period. So, yes, the climate is changing, but as to the root cause, I do not buy the argument that humans are the only thing causing it. I don't know of a single scientist that has claimed that man is solely responsible. However the weather records we see now can be and are very likely attributed to man's 'contribution' to global warming. As far sun activity effecting atmospheric temperatures, it is myth. It's often considered "common sense" that global warming is caused by the Sun. After all, the Sun is the source of almost all of the energy on Earth. It is also common sense to believe that in summer, the sun must be closer to earth. Both questions are put to rest with the knowledge that atmospheric temperature is effected by the sun's radiation and that's why it's warmer in summer when the sun is the farthest from the earth in our orbit. Foster and Rahmstorf (2011) used multiple linear regression to quantify and remove the effects of the El Niño Southern Oscillation (ENSO) and solar and volcanic activity from the surface and lower troposphere temperature data. They found that since 1979, solar activity has had a very slight cooling effect of between -0.014 and -0.023°C per decade, depending on the data set Like Foster and Rahmstorf, Lean and Rind (2008) performed a multiple linear regression on the temperature data, and found that while solar activity can account for about 11% of the global warming from 1889 to 2006, it can only account for 1.6% of the warming from 1955 to 2005, and had a slight cooling effect (-0.004°C per decade) from 1979 to 2005. Similarly, Schurer et al. (2013) uses multiple linear regression and finds that the sun is unlikely to have caused more than 0.15°C of the observed approximately 1°C warming over the past 300 years.
