China is the 4th largest country in terms of geographical size and the largest in population size. Accordingly, human-induced climate change from greenhouse trace gases would be of major concern to China's leaders. So, what does a fact check reveal of China's modern climate change due to human Co2 emissions?
Frankly, little, if any, emission impact on present climate change based on new Chinese peer-reviewed research.
The chart on the left represents a 341-year proxy temperature reconstruction for the southwest region of China.
Clearly, unprecedented temperatures occurred during the mid to late 1700s. This record shows that modern temperatures, which supposedly have been influenced by human emissions, are yet to rival temperatures from much earlier periods.
Also, one can discern a cyclical pattern that the study's scientists attributed to nature climate oscillations - trace greenhouse gases do not explain this periodical climate pattern.
The chart on the right represents a 500-year streamflow analysis for a western region of China.
Again, a pattern of constant change, from low to high to low, appears to be due to natural climate variations. The late 20th and early 21st century observations seem remarkably similar to those in the distant past, suggesting that Co2 emissions are not a factor influencing streamflow.
Fact Check: As these two studies from China indicate, modern industrial/consumer emissions from fossil fuels are not a major component of climate change. This research adds to the huge compilation of prior peer-reviewed studies that confirm modern climate change is not out of the ordinary, and highly likely due to natural causes, not human-induced as speculated my many.
