Jennifer Francis, Top Climatologists Explain How Global Warming
Wrecks the Jet Stream and Amps Up Hydrological Cycle To Cause
new program, posted above and produced by Australian Broadcasting,
provides in depth analysis of the cutting edge climate science that
begins to reveal how human-caused climate change is causing
increasingly dangerous weather.
program explores past extreme events like the European and Russian
heatwaves that together resulted in nearly 100,000 deaths, the
devastating floods of Pakistan, and this year’s extreme Northern
Hemisphere winter and shows how climate change was the driving factor
in each. The program also explores issues I’ve been covering here —
like how melting sea ice causes the Jet Stream to meander, resulting
in more persistent weather patterns that drive extreme events. The
chief pioneer in this research, Dr. Jennifer Francis, provides some
well rendered and somewhat chilling explanations about this key
feature of our new atmosphere.
aspect explored is how global warming greatly increases the
hydrological cycle. New findings have shown that just 1 degree
Celsius of global temperature rise increases the intensity of the
global hydrological cycle by a whopping 7%. Evaporation increases by
7%, fueling more droughts and heatwaves, and rates of rainfall during
storms also increases by 7%, further increasing the damage caused by
the most extreme storms. Predicted rises in temperatures of 2, 4, 6
or more degrees Celsius would result in a catastrophic amplification
of the hydrological cycle by 15, 30, 40 percent or greater. This
basic underpinning of storm and drought formation shows how
devastating to human systems such a massive change in major weather
drivers would be.
the program explores how even a .8 degree Celsius rise in
temperatures has resulted in more deadly heatwaves. The great
European, Russian, US and Australia heatwaves of the past decade are
all explored in this particular expose.
