Nearly all of the alleged anthropogenic link to climate change can be removed simply by exchanging and/or replacing biased temperature and solar activity data sets.
A new study authored by 37 scientists in the journal Climate finds using rural-only Northern Hemisphere temperature data (i.e., removing artificial, non-climatic urban heat effects) reduces the post-1850 warming trend from 0.89°C per century to 0.55°C per century.
Further, using a total solar irradiance (TSI) dataset neglected by the IPCC (Hoyt and Schatten, 1993, updated to present) allows TSI to explain up to 87% of modern warming.
Variations in cloud cover, albedo, and natural ocean circulations may also be factors arising from internal climate variability that could explain modern climate changes.
In summary, then, much of modern global warming’s alleged link to human activity may have been formulated by selecting data that align with the hypothesis, and neglecting or dismissing data which do not.
