Climate Change and You
Email this Mix
Slide 1 - CLIMATE CHANGE AND YOU
- First of all, you should know that weather and climate are not the same thing.
Slide 3 - WEATHER IS:
- Short term
- Limited area
- Can change rapidly
- Difficult to predict
- WEATHER is what’s happening outside your window right now.
Slide 4 - CLIMATE IS:
- Long term
- Wide area
- Seasonal changes
- Measured over long spans of time
- CLIMATE is the average of many years of weather observation.
Slide 5 - Climate is affected by many factors
- ABIOTIC FACTORS:
- Ocean Currents
- Solar Radiation
- Orbital Variations
- Volcanic Activity
- BIOTIC FACTORS:
Slide 6 - Greenhouse Gases are essential to our climate
Slide 7 - Planets with very little greenhouse effect are either very cold…
- Pluto’s average temperature is –370° F
Slide 8 - On Mars, there is about a 300 degree F difference between high and low temperatures
- …or they have huge temperature swings from day to night.
- (http://quest.nasa.gov/aero/planetary/mars.html )
Slide 9 - Planets with abundant greenhouse gases are very hot
- The average temperature on Venus is about 855° F!
Slide 10 - …which is just right…
- …for the moment, anyway.
- …and then there’s Earth….
Slide 11 - Water vapor
- Carbon dioxide
- Nitrous oxide
- A number of greenhouse gases occur naturally in the Earth’s atmosphere
Slide 12 - With no greenhouse gases at all in its atmosphere, scientists estimate that Earth’s average atmospheric temperature would be about -18° C, or about 0°F
Slide 13 - The greenhouse gas content of the atmosphere is being altered by human activity.The result of this change is global warming.
Slide 14 - Evidence of Climate Change comes from many different sources.
Slide 15 - Glaciers are melting away worldwide
- Agassiz Glacier, Montana, in 1913…
- Pasterze Glacier, Austria, in 1875…
- …and in 2005
- …and in 2004
Slide 16 - Ice cores yield information and actual samples of Earth’s past atmosphere
Slide 17 - Tree ring data show a warming trend
Slide 18 - Animal and plant life is changing
- 2/3 of European butterfly species studied have shifted their ranges northward by as much as 150 miles. (Parmesan, 1996; Parmesan et al., 1999)
- An analysis of the distributions of British birds found that many species have moved north by an average of 18.9 km. (Thomas et al, 1999)
- At Boston's Arnold Arboretum, plants are flowering eight days earlier on average than they did from 1900 to 1920. (Primack et al,2004)
Slide 19 - Climate change seems to accelerating
- Each of the 48 continental states experienced above-normal annual temperatures in 2006. For the majority of states, 2006 ranked among the 10 hottest years since 1895. ( NOAA)
Slide 20 - More Greenhouse Gases Mean a Warmer Earth
Slide 21 - Who creates greenhouse gases?
Slide 22 - Carbon Dioxide
- In the distant past, the Earth was much warmer. High levels of Carbon Dioxide in the atmosphere fueled lush growth, some of which was stored in the form of fossil fuels.
Slide 23 - www.epa.gov/climatechange
- Carbon Dioxide in Earth’s atmosphere has risen by about 30% since the beginning of the industrial revolution. Most of the increase is due to the combustion of fossil fuels, which releases the long-stored CO2 back into the atmosphere.
Slide 24 - Methane
- Methane is released by coal mining, landfills, and by agriculture, particularly through the digestive processes of beef and milk cows.
Slide 25 - Nitrous Oxide
- Nitrous Oxide is produced by cars, by fossil fuels used for heat and electricity, and by agriculture.
Slide 26 - First we must admit that climate change is everyone’s problem. No agency, government, or scientist can “fix it” for us. We are all in this together.
- We got here because of our lifestyle. So our lifestyle has to change.
- Here’s what you can do…
- What can be done?
Slide 27 - Install programmable thermostats.
- Check and repair weather stripping on doors and windows.
- Adjust your clothing instead of the thermostat.
- Keep furnace and AC filters clean.
- Consider closing off unused rooms.
- Install insulated drapes.
- Plant deciduous trees on the sunny side of your home.
- Heating and Cooling
- What other ways can you conserve heat and AC?
Slide 28 - Conserve Hot Water
- Take shorter showers.
- Install low flow shower heads.
- Install a blanket on your hot water heater.
- Insulate hot water pipes.
- Wash laundry in cold water.
- Only run the dishwasher if it’s full.
- Fix leaky faucets
- What other ways can you cut down on hot water use?
- In the average home, 17% of energy is used to heat water. http://www.eia.doe.gov/kids/energyfacts/uses/residence.html
Slide 29 - Plan ahead – do several errands in a single trip.
- Walk or bike. It’s healthier anyway.
- Clean out the junk in the trunk. Lighter cars get better mileage.
- Make sure your engine is properly tuned.
- Keep your tires properly inflated.
- Carpool or ride the school bus.
- Support public transportation.
- Consider a smaller car or a hybrid for your next vehicle.
- Conserve in the Car
- What other ways can you use less gas?
Slide 30 - Unplug chargers for cell phones and other appliances when not in use.
- Get in the habit of turning lights and appliances off.
- Vacuum the coils on the back of the fridge monthly.
- Change to compact fluorescent bulbs.
- Make your next computer a laptop.
- Install timers or motion sensors on outdoor lights.
- Conserve Electricity
- What other ways can you conserve electricity?
Slide 31 - Recycle and buy recycled products.
- Choose products that have less packaging.
- Reuse, repair, or donate.
- Don’t buy it unless you really need it.
- Carry cloth bags when shopping.
- Use a refillable travel mug or water bottle.
- Give your time instead of material gifts, or donate to a charity in the recipient’s name.
- Reduce waste
- What other ways can you cut down on waste?
Slide 32 - There’s no place like home…
- …and there may never be again. Do your part.
