Last Year over 250 peer revewed papers published questioning human based climate change. German climate site!

The German climate science site, No Tricks Zone( has assembled a list of approximately 250 peer-reviewed academic articles published in 2015 demonstrating nature has a significant role in ongoing climate change, contrary to the dominant meme humans are solely or primarily responsible for catastrophic climate change.
Many of the articles stress solar activity plays a dominant role in climate change. For instance:
Mounting evidence from proxy records suggests that variations in solar activity have played a significant role in triggering past climate changes. Our results indicate a close link between solar activity and SSTs in the northern North Atlantic during the past 4000 yr. ... Furthermore, the high-resolution SST record indicates that climate in the North Atlantic regions follows solar activity variations on multi-decadal to centennial time scales. (Geology, February 2015)
[I]n order to account for the problem of urbanization bias, we compile a new estimate of Northern Hemisphere surface air temperature trends since 1881, using records from predominantly rural stations in the monthly Global Historical Climatology Network dataset. A strong correlation is found ..., implying that solar variability has been the dominant influence on Northern Hemisphere temperature trends since at least 1881. (Earth Science Reviews, November 2015)
There has been widespread investigation of the drivers of changes in global temperatures. However, there has been remarkably little consideration of the magnitude of the changes to be expected over a period of a few decades or even a century. [W]hile some portion of the temperature change observed in the 20th century was probably caused by greenhouse gases, there is a strong likelihood that the major portion was due to natural variations. (Energy and Environment, April 2015)
A host of articles addressed the positive role the changing climate and increasing carbon dioxide have had on plant growth and agricultural yields. For instance:
We quantified the temporal trend and climatic sensitivity of vegetation phenology in dryland ecosystems in the US Great Basin during 1982–2011. Our results indicated that vegetation greenness in the Great Basin increased significantly during the study period. … [C]limate warming played a strong role in extending GSL [growing season length] that in turn resulted in the upward trend in mean vegetation greenness during 1982–2011. (Biogeosciences, July 2015)
In summary, climate change has prolonged FFP [frost free period], increased the heat resource, and slightly changed solar radiation resource during crop growing season, which is beneficial for agriculture in Northeast China. (International Journal of Climatology, September 2015)
The Sahel region of Northern Africa is home to more than 50 million people for whom summer rainfall is a crucial water resource in terms of food security and societal stability. [During 1982–2012, we detected a significant increase in both vegetation greenness and monsoon rainfall over the Sahel since the early 1980s. (acknowledgements to Heartland Institute Chicago)

Graphic that proves recent high temperatures due to El Nino not carbon dioxide. Dr Ryan Maue Weatherbell

This graphic by Dr Ryan Maue of Weatherbell shows tropical temperature plotted with global temperature. From April to October 2015 it is clearly seen that tropical temperature, representing the El Nino rises considerably above the global temperature.  From October they both then move in synchronous movement proving that the high temperatures we have experienced are entirely due to the natural Pacific El Nino and nothing to do with human carbon dioxide.
