strange stuff happening
the temperature globally is on the raise, the CO2 driving it
you have the suns variations as a possible driver
The strong correlation between reconstructed temperature and solar activity suggests solar forcing as a main driver for temperature variations during the period 1250–1850 in this region. The precisely dated record allowed for the identification of a 10–30 year lag between solar forcing and temperature response, underlining the importance of indirect sun-climate mechanisms involving ocean-induced changes in atmospheric circulation. Solar contribution to temperature change became less important during industrial period 1850–2000 in the Altai region
The strong rise in temperature in the Altai between 1850 and 2000 can not be explained by solar activity changes, but rather by the increased concentration of the greenhouse gas CO2 in the atmosphere
you want to use to prove .. That it's all due to the sun? And CO2 becoming some imaginary driver, according to you?
scientists seem to recognise the sun’s variations are not a "possible” but at least as a probable driver
To understand what causes low interplanetary magnetic fields and what causes coronal holes in general. This is all part of the solar cycle. And all part of what causes effects on Earth
But the fact that three completely different views of the Sun point in the same direction is a powerful indicator that the sunspot cycle may be going into hibernation .. All three of these lines of research to point to the familiar sunspot cycle shutting down for a while. “If we are right,” Hill concluded, “this could be the last solar maximum we’ll see for a few decades. That would affect everything from space exploration to Earth’s climate.”
I think that most of us recognise the sun as the major driver .. scientists seem to recognise the sun’s variations are not a "possible” but at least as a probable driver
prove .. That it is all due to the sun
Many sceptics recognise that atmospheric CO2 has a small forcing effect on global temperatures (less than 2C for a doubling if all other drivers were to remain constant). There are plenty scientists looking elsewhere for other drivers having much greater significance that CO2
prove .. CO2 becoming some imaginary driver
the sun is a driver too, nobody doubts that
But whether it has driven us to the climate we see today? Nope
Want to link me the stud(y)ies stating your thoughts, so I can read it?
stop trying to play out solar scientists against other disciplines. It makes me wonder what you are Yelder?
There are a lot of uncertainties in science, and it is indeed likely that the current consensus on some points of climate science is wrong, or at least sufficiently uncertain that we don’t know anything much useful about processes or drivers. ..
Pointing at solar variables is all good and proper, but I prefer something more substantial, like a study proving it
Just link me to it, but try to avoid 'pay sites' please
BTW, the very interesting paper “Solar Influences on Climate” by Gray et al. (http://solar-center.stanford.edu/sun-on-earth/2009RG000282.pdf) covers the subject in great detail
.. Stanford Solar Center .. provides teachers, students, and the interested public with the latest information about the Sun. .. Stanford scientists study the Sun via two space-based instruments, the Solar Dynamics Observatory and the Solar and Heliospheric Observatory, as well as a ground-based telescope called the Wilcox Solar Observatory on the Stanford University campus ..
Understanding the influence of solar variability on the Earth’s climate requires knowledge of solar variability, solar-terrestrial interactions, and the mechanisms determining the response of the Earth’s climate system. We provide a summary of our current understanding in each of these three areas. Observations and mechanisms for the Sun’s variability are described, including solar irradiance variations on both decadal and centennial time scales and their relation to galactic cosmic rays. Corresponding observations of variations of the Earth’s climate on associated time scales are described, including variations in ozone, temperatures, winds, clouds, precipitation, and regional modes of variability such as the monsoons and the North Atlantic Oscillation. A discussion of the available solar and climate proxies is provided. Mechanisms proposed to explain these climate observations are described, including the effects of variations in solar irradiance and of charged particles. Finally, the contributions of solar variations to recent observations of global climate change are discussed... A full understanding of the influence of solar variability on the Earth’s climate requires knowledge of .. the short- and long-term solar variability, .. solar-terrestrial interactions, and .. the mechanisms determining the response of the Earth’s climate system to these interactions .. There have been substantial increases in our knowledge of each of these areas in recent years and renewed interest because of the importance of understanding and characterizing natural variability and its contribution to the observed climate change .. Correct attribution of past changes is key to the prediction of future change... Of greater importance to climate change issues are longer-term drifts in this radiative forcing. .. However, observations indicate, at least regionally, larger solar‐induced climate variations than would be expected from this simple calculation, suggesting that more complicated mechanisms are required to explain them. .. A great number of papers have reported correlations between solar variability and climate parameters. One relatively early association .. examined historical evidence of weather conditions in Europe back to the Middle Ages, including the severity of winters in London and Paris, and suggested that during times of few or no sunspots, e.g., during the Maunder Minimum (1645–1715), the Sun’s radiative output was reduced, leading to a colder climate. Although many of the early reported relationships between solar variability and climate have been questioned on statistical grounds, some correlations have been found to be more robust, and the addition of more years of data has confirmed their ignificance. .. Mechanisms proposed to explain the climate response to very small solar variations can be grouped broadly into two categories. The first involves a response to variations in solar irradiance. .. The second mechanism category involves energetic particles, including solar energetic particle (SEP) events and GCRs. .. At stratospheric heights .. This region of the atmosphere has the potential to affect the troposphere immediately below it and hence the surface climate. Estimated stratospheric temperature changes associated with the 11 year SC show a signal of 2 K over the equatorial stratopause (50 km) with a secondary maximum in the lower stratosphere (20–25 km ... The direct effect of irradiance variations is amplified by an important feedback mechanism involving ozone production, which is an additional source of heating .. The origins of the lower stratospheric maximum and the observed signal that penetrates deep into the troposphere at midlatitudes are less well understood and require feedback/transfer mechanisms both within the stratosphere and between the stratosphere and underlying troposphere .. While the testing of solar influence on climate via changes in solar irradiance is relatively well advanced, the GCR cloud mechanisms have only just begun to be quantified. ..In the context of assessing the contribution of solar forcing to climate change, an important question is whether there has been a long-term drift in solar irradiance that might have contributed to the observed surface warming in the latter half of the last century. Reconstructions of past TSI variations have been employed in model studies and allow us to examine how the climate might respond to such imposed forcings. The direct effects of 11 year SC irradiance variations are relatively small at the surface and are damped by the long response time of the ocean-atmosphere system. However, model estimates of the response to centennial time scale irradiance variations are larger since the accumulated effect of small signals over long time periods would not be damped to the same extent as decadal-scale responses. .. There are also large uncertainties in estimates of long‐term irradiance changes .. the low level of scientific understanding of the solar influence is noted [IPCC, 2007]. The uncertainty is probably also underestimated because of the poorly resolved stratosphere in most of these models. Nevertheless, IPCC  concludes that changes in the Sun have played a role in the observed warming of the Earth since 1750, but these changes are very small compared to the role played by increasing long-lived greenhouse gases in the atmosphere. .. The purpose of this review is to present up-to-date information on our knowledge of solar variability and its impact on climate and climate change, as an update to previous reviews .. Further observations and research are required to improve our understanding of solar forcing mechanisms and their impacts on the Earth’s climate.
