Slides, Climate Change, and How to Reduce Emissions


Effects of climate change on agriculture

Controversies in public policies for reducing emissions

Average Annual Temp in NE  1899-2000

Average Winter Temp in NE 1899-2000

What’s So Bad About Warmth?

Range of Sugar Maple

Spatial Variation of Days with Snow on Ground 1971-2000

Average Growing Season

Apple & Grape Bloom Dates


“CO2 Fertilization Effect” and Inceased Growing Season–Plant Disease Triangle

Plant Canopy Effects

Wheat Yields in Developing Countries

Pest Patterns Changing

Leaf-Feeding Insects Eat More

Malaria Spreads as Temp Rises

Many Weeds Thrive with Increasing CO2, Temp

CO2 and Herbicides

Poison Ivy Thrives

Extreme Precipitation (>2 inches in 48 hrs.)

Heat Stress Affects Quality of Produce

High Temp Stress Counters CO2 Fertilization

Heat Stress and Livestock

Precipitation Trends in 20th Century


Burning Up

Combining Burning with Leveraging

Natural Cycles Are Now Dominated

1000 Years Temp & CO2

Hurricane Tracks, 1985-2005


Ocean temp > 79°F can cause circling thunderstorms to become a hurricane.

Most hurricanes degrade while crossing FL.

For those hurricanes that survive into Gulf, can become extremely dangerous before landfall.

Gulf water often gets as high as 87°F, pumping enormous quantities of water vapor, hurricane fuel, into storm.

Hurricane Power Expenditure

Seismic Activity of Glaciers in Greenland

Global Glacial Volume Decrease

Will Scotty Beam Us Aboard?

Just as every emission: Solar

Cap–Trade & Offsets   C Tax

Cheap Coal? High Cost!

CO2 Capture and Storage



Generated from fossil fuels

Decades before renewables for grid and H to power fleet of vehicles

Fuel cells still expensive

Storage of H tech challenge

Transport–fueling: $500B

Large H fleet distant

Focus: plug–in hybrids

Ethanol (Ethyl Alcohol–Booze, Hooch)

Soybean and corn: fossil fuels used.     Fuel from food.

Methane used in processing.

Diesel trucks to transport ethanol.

Savings < 20%, but cattle eat waste products: <2 days, < rot.

Not good solution until low cost, high volume enzymes: fibers in grass and stalks into sugars for fermentation into ethanol.

Switchgrass on land marginal for food.

Three Mile Island Nuclear Power Station

More Than Meets the Eye

Natural Drivers vs. Human Forcing

Greenland: 100,000 Years

Civilization developed during an era with an unusually narrow range of temps.

Increasing temps will challenge civilization and biosphere.
