I have seen in many places (less so here) where even the thought of solar
output effecting climate is derided.

The combined
effects of
climate change could reduce potential
output by up to 30 percent in Africa and up to 21 percent in Asia, the FAO Chief noted.
Periods of volcanism can cool the
climate (as with the 1991 Pinatubo eruption), methane emissions from increased biological activity can warm the
climate, and slight changes in solar
output and orbital variations can all have
climate effects which are much shorter in duration than the ice age cycles, ranging from less than a decade to a thousand years in duration (the Younger Dryas).
Thanks for publishing this, there are folks who denigrated the work of scientists that claimed a solar -
climate (temperature) link because the variability in solar energy
output just wasn't enough to explain the temperature swings, and perhaps they now realize that there could be another mechanism - similar to a transistor where small changes in gate voltage can affect large changes in power transmission - whereby solar activity can create significant
effects on temperature.
Sure industrialisation has increased the
output of pollution of many kinds, however, what
climate «science» can't prove is that that industrialisation has actually had any significant
effect on the
climate.
A recent meta - analysis published in the journal Nature
Climate Change, by Challinor et al. (2014) examines 1,722 crop model simulations, run using global climate model output under several emissions scenarios, to evaluate the potential effects of climate change and adaptation on crop

climate change and adaptation on crop yield.
The casual disregard of the internal variations / cycles and the «elmination» of any external factors (galactic radiation
effects are a very very interesting for me at the moment - especially due to the inverse relationship with solar
output) disguise the level of ignorance that we have about the
climate as a whole.
Working from collision data from Transport Canada, weather data from Environment Canada and the
output of regional
climate models, they explored how future changes in precipitation could
effect road safety in the Greater Vancouver area.
In terms of environmental and
climate change
effects, organic farming is less polluting than conventional farming when measured per unit of land but not when measured per unit of
output.
Yes, the evidence overwhelmingly point to anthropogenic
climate change:
Output of greenhouse gases (mainly carbon dioxide, methane, nitrous oxide) has soared to extremes the last few decades, and we are seeing the effects of this o
Output of greenhouse gases (mainly carbon dioxide, methane, nitrous oxide) has soared to extremes the last few decades, and we are seeing the
effects of this
outputoutput.
Integrated physiological and economic models (e.g., Fischer et al., 2005a) allow holistic simulation of
climate change
effects on agricultural productivity, input and
output prices, and risk of hunger in specific regions, although these simulations rely on a small set of component models.
On the vital question of how to approach
climate change, the most influential economist is William Nordhaus whose explicit position is that we should decide to reduce greenhouse gas emissions only if cost - benefit analysis or an optimisation model concludes that the net benefits to humans are positive, where the relevant
effects are essentially impacts on economic
output (Nordhaus and Yang, 1996).
Fair enough, but looking at the cluster of results being so consistent and consistently wrong, they are either making huge mistakes about what influences the
climate, or huge misallocation of forcing
effects, or huge simplifications that prevent the model
output from occasionally reproducing reality.
The climatic system / oceanic system are driven by the sun, therefore it stands to reason any changes in solar
output (variations) will have an
effect on these two systems which in turn will have an
effect on the
climate.
I have previously described why the solar
effect on
climate is not as generally thought but for convenience I will summarise the issue here because it will help readers to follow the logic of the NCM.Variations in total solar power
output on timescales relevant to human existence are tiny and are generally countered by a miniscule change in the speed of the hydrological cycle as described above.
Computer models are an essential tool in understanding how the
climate will respond to changes in greenhouse gas concentrations, and other external
effects, such as solar
output and volcanoes.
