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.

A darker Arctic is boosting global warmingFrom1979 to 2011, less reflecting ice, more absorbing water made North Pole warm twice as

fast as the rest of the earth. http://www.pnas.org/content/early/2014/02/13/1318201111.abstract

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 ArcticThe 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.

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-way/2014/02/16/277911739/warming-arctic-may-be-causing-jet-stream-to-lose-its-way

ANOMALOUSLY HIGH SEA SURFACE TEMPERATURES OF +5 deg. C PUT MORE WATER VAPOR IN THE ATMOSPHERE. STORMS CARRY IT OVER THE COLD LAND TO MAKE MORE SNOW.

The rate of sea level increase correlates with the blue line of CO2 increase.

Sea level rise is a proxy for global temperature, due to thermal expansion (50%) & the melting of ice (50%)

Sea level rise rate has increased 4 times: 3.1 mm/year ( 1 ft/100 yr. ) now from 0.8 mm/year in 1900

CONCLUSIONS1. 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.

Global temperatures have risen since 1960, but rate of sea level rise has be greater.
