Read here. The IPCC and other global warming alarmists have claimed that snowpacks of mountainous areas are declining. Actual scientists decided to investigate this claim to determine if it was based on factual evidence or based on hypothetical speculation.
Per peer-reviewed research conducted by Chinese scientists, they analyzed an area of Tibet and discovered that snowpack levels over the past 100 years reveal no significant trends and the levels are quite variable. The most recent levels indicate snowpack is well above previous lows of earlier decades of the 20th century. Another IPCC prediction proven wrong. (click on image to enlarge)
"“The most notable features of the reconstruction are the higher snow accumulation around 1990. The reconstruction also shows that the Gongga Mountain experienced some lower snow-depth episodes during 1910s, 1930s, 1950–1980, and later 1990s. The higher snow-depth intervals occurred during 1910s, 1940s, and the period around 1990 with the highest values during past 100 years. We defined extreme snowpack depth years as those years with values more than one standard deviation (plus or minus) from the average. Although there are several clusters of extreme years over the past century, the century is notable for the long period of snow-depth variations in a normal way except the higher snowpack depth values around 1990.”.....So, what we get here is a classic case of an apparent decline in snowpack from the late-1980s to the near-present, and someone might be tempted to suggest the decline is related to global warming. The Chinese scientists figured a way to reconstruct snowpack going back over 100 years, and that time series shows no evidence whatsoever of any downward trend (in fact, there appears to be a slight upward trend in the data)."
