WEATHER EXTREMES ARE INCREASING.
Record-Cold and Snowfall in New England during 2015 winter.
-Record high sea temps, 11.5 C, put more
water vapor (snow) in the atmosphere.
-Record-Hot West Sees First 100-Degree Temperature of 2015.
- CA 4 yr. drought longest in history.
Wet areas getting wetter: Floods, Snow
Dry areas getting drier: CA Drought, Wildfires.
Rising sea levels are a better measure of global warming than air temperaure.

3. A darker Arctic is boosting global warming
From1979 to 2011, less reflecting ice, more absorbing water made North Pole warm twice as
fast as the rest of the earth.

4. PAST COLD ARCTIC PRESENT WARMER ARCTIC
Higher pressure sub-tropic constrained the
low-pressure arctic
Lower pressure difference allows
waves of arctic air to invade the
South: Warmer & Colder Winters.
Cold Air Oscillates South from the Arctic
The Arctic is warming twice as fast as the rest of our earth.
Therefore the temperature and the accompanying pressure difference that used to keep arctic
air up North comes South, bringing cold air to Atlanta & New Orleans.

6. The jet stream that circles Earth's north pole travels west to east. But when the jet stream
interacts with a Rossby wave, as shown here, the winds can wander far north and south,
bringing frigid air to normally mild southern states. http://www.npr.org/blogs/thetwo-

15. CONCLUSIONS
1. WEATHER EXTREMES ARE INCREASING
-Wet areas are becoming wetter: Floods, Snow
Atmosphere holds more water at higher temps.
-Dry areas, drier: Droughts, Wildfires
2. RISING SEA LEVELS ARE A BETTER
MEASURE OF GLOBAL WARMING
THAN SURFACE TEMPERATURE.

Editor's Notes
Oceanic heat sink. Evolution of the ocean heat content (OHC) at several depths of the global ocean between 1980 and 2011. Since 2000, the subsurface ocean has warmed much faster than in the preceding two decades; this ocean warming may explain why average atmospheric temperatures have not risen during the past decade. The gray bars show the timing of the El Chichón and Pinatubo volcanic eruptions. The yellow and blue bars show the timing of several key El Niño and La Niña events.
