1. Earth’s tilt (obliquity) relative to the plane of the orbit.

• Today the tilt is about 23.5 degrees and slowly straightening up.

• It takes about 41,000 years to go through the full cycle from minimum tilt (22.1 degrees) to maximum tilt (24.5 degrees) then back to minimum tilt.

2. Apsidal precession • Earth is now closest to the sun in January and furthest

from the sun in July. • But the day in the year at which Earth is closest to the

sun moves through the entire calendar over the course of 20,000 years.

3. Eccentricity of Earth’s orbit • At present the eccentricity is about 1.7%• The eccentricity of the earth’s orbit varies from 0%

(circular) to 6% about every 100,000 years.

Survival of Mankind

Slide 39

“The emission of green house gases … is causing global warming at a rate that began as significant, has become alarming and is simply unsustainable in the long term. ….. By unsustainable, I do not mean a phenomenon causing problems of adjustment.

I mean a challenge so far reaching in its impact and irreversible in its destructive power, that it alters radically human existence.

There is no doubt that the time to act is now.”

Solution 11 – Conservation – Smart Switches

1. Sensor Switch - Sense body heat or motion to turn lights on and off according to presence in room.

2. Cycling switches - Control the amount of up time for a particular appliance during Peak Periods. e.g. your air conditioner, furnace, fans or water heater could be set to only operate at say one half of its normal time during peak (high rate) periods.

3. Smart Strip - Fully turn off appliances such as plasma TVs, DVDs, fax machines, computers, printers, monitors, cable modems and routers that continue to draw 40% – 70% of “On” power when turned off.

Slide 54

Solution 12 – Recycling

Slide 55

Summary – Government ActionWhat can governments do?1. Phase out coal fired power plants.2. Provide incentives for low or zero carbon energy sources such as

nuclear, wind, solar, geothermal, biomass and bio fuel.3. Provide incentives to home and business owners to improve the

insulation of their homes and buildings to save energy for heating and cooling.

4. Provide incentives for homes and businesses to convert from fossil fuels to low or zero carbon sources such as solar, wind, geothermal or biomass.

5. Provide incentives for low or zero carbon methods of transportation such as electric, hybrid, compressed air, bio fuel or wind.

6. Encourage recycling.7. Improve urban planning and zoning so people can drive or bicycle

to work in under 20 minutes.9. Support and participate with a World Authority to set targets and

monitor progress of each country to assure they are meeting their targets.

Slide 56

Global Warming and what we can do about it

Summary – Consumer Action (You)

What can you do?1. Ask your power company about green power options such as Bull Frog Power, Green Power Network and Renewable Energy. 2. Buy CFL or LED light bulbs and take advantage of any incentives to

improve the insulation of your home to conserve energy. 3. Trade in your SUV for a medium sized Hybrid or high mileage car to

reduce your transport carbon emissions by 70%. Or get an Air Car to reduce your transport carbon emissions by almost 100%. Make greater use of public transportation and where possible walk or ride a bike to work.

4. Ask your employer to have an energy audit done to look for opportunities for conserving energy.

5. And finally you must vote for a political party that supports carbon reductions and international commitments like the Kyoto Accord.

And remember, if enough of us change our power sources to wind, solar, geothermal and biofuel the cost of these options will plummet.

Slide 57

Success Can Breed Success to Save our Planet

As new developments arise in zero carbon energy and conservation; businesses and people will start to believe that we can actually save the planet.

Low carbon energy will generate huge economic growth in fields like solar energy, wind energy, nuclear energy, geo thermal energy, bio fuel, low carbon transportation, low carbon buildings and other areas.

Imagine coal miners being offered jobs in factories making wind turbines or solar panels. Imagine oil workers being offered jobs in a factory making hybrid cars.

As the huge potential of a green economy becomes obvious, more and more businesses and people will get on board.

Success will breed success.

And remember there is no “next season”, this is our last chance.Slide 58
