Carbon dioxide levels have nothing to do with global warming,or climate change. The science is far from settled.investorvillage.com Re: Global warming-maybe not so fast if Maunder Mimimum Coming and if representative of mid 1600's to early 1700's NASA latest.....beginning to shift their story to cooling......paper released last week. science.nasa.gov Summary....."NASA reports this week that we may be on the verge of another Maunder Minimum (a period with an unusually low number of sunspots, leading to colder temperatures): Much has been made of the probable connection between the Maunder Minimum, a 70-year deficit of sunspots in the late 17th-early 18th century, and the coldest part of the Little Ice Age, during which Europe and North America were subjected to bitterly cold winters. The mechanism for that regional cooling could have been a drop in the sun’s EUV output; this is, however, speculative. NASA: We May Be On the Verge of a Mini Maunder Event The yearly averaged sunspot number for a period of 400 years (1610-2010). SOURCE: Courtesy of NASA Marshall Space Flight Center. *** The sun could be on the threshold of a mini-Maunder event right now. Ongoing Solar Cycle 24 is the weakest in more than 50 years. Moreover, there is (controversial) evidence of a long-term weakening trend in the magnetic field strength of sunspots. Matt Penn and William Livingston of the National Solar Observatory predict that by the time Solar Cycle 25 arrives, magnetic fields on the sun will be so weak that few if any sunspots will be formed. Independent lines of research involving helioseismology and surface polar fields tend to support their conclusion. NASA explains that interactions between the sun, sources of cosmic radiation and the Earth are very complicated, and it takes an interdisciplinary team of heliophysicists, chemists and others to quantify what is really going on. And the Earth’s climate is also affected by cosmic radiation. So – even if NASA’s prediction of a period of an unusually low amount of sun spots is proven correct – it is hard to know whether that will lead to a large or small reduction in temperature trends." As an aside, I came across the work of Dr. Theodor Landscheidt en.wikipedia.org a few years back "New Little Ice Age Instead of Global Warming?" published in 2003 shortly before his death. landscheidt.wordpress.com In revisiting the topic, I find other researchers have "picked up the planetary balls" with additional research tying planetary cycles to sunspot cycles. Specifically the recent work of Carl Smith and others is captured here landscheidt.info .....very interesting reading.... ....their conclusion.....it likely is going to get progressively colder over the next 20 years .....not a Maunder Minimum as Landscheidt predicted and NASA now talks about above....more likely a pseudo Dalton Minimum....????
