What is Climate Change?:

What is Climate Change? Climate is the average weather at a given point and time of year, over a long period (typically 30 years). We expect the weather to change a lot from day to day, but we expect the climate to remain relatively constant. If the climate doesn’t remain constant, we call it climate change.

Definition of Climate Change :

Definition of Climate Change " Climate change " refers to any long-term  change  in Earth's  climate , or in the  climate  of a region or city. This includes warming, cooling and changes besides temperature.

Animal and plant life is changing:

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)

Major Causes of Climate Change:

Major Causes of Climate Change Natural Causes the arctic tundra and wetlands release methane, a greenhouse gas Earth naturally has a cycle of climate change that occurs every 40, 000 years the sun’s solar energy output is changing and naturally increases Earth’s average temperature by about 1 ºC every century Earth’s orbit and tilt alter in relation to the sun, which changes solar energy output Volcanic eruptions Human Causes Increasing green house gas emissions from burning fossil fuels-oil, coal, gas Pollution, smog from factories Large forests have been cut down (trees absorb CO 2 and pollution, deforestation creates about 6 billion tons of CO 2 per year) Increasing world population-more people requires more food, energy, transportation, etc. Farms animals release methane from their wastes. More people also means more CO 2 production from respiration and less trees to make room for human population

Slide 36:

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?

Strategies to combat Climate Change:

Strategies to combat Climate Change Walk or bike instead of driving a car Use compact fluorescent light bulbs as these energy-efficient Reduce heating and air-conditioning in your homes Use car pools whenever possible Buy local and seasonal produce Put a lid on vessels when cooking Turn off all electrical appliances instead of putting them on standby when not in use Unplug electrical appliances when fully charged Keep the opening of fridge and freezer doors to the minimum Use pressure cookers as much as possible RENEW, RECYCLE, REUSE  

Slide 38:

Keep AC filters clean. Consider closing off unused rooms. Plant deciduous trees on the sunny side of your home. Heating and Cooling

Conserve Hot Water:

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 In the average home, 17% of energy is used to heat water.

Slide 40:

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

Slide 41:

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

Slide 42:

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?

Major Organizations against climate change:

Major Organizations against climate change Greenpeace is the leading independent campaigning organization that uses peaceful protest and creative communication to expose global environmental problems and to promote solutions that are essential to a green and peaceful future . Greenpeace

The Intergovernmental Panel on Climate Change (IPCC):

The Intergovernmental Panel on Climate Change (IPCC) The Intergovernmental Panel on Climate Change (IPCC) is the international body for assessing the science related to climate change.

World Meteorological Organization :

World Meteorological Organization The WMO is the U.N.-based international organization for cooperation among national weather agencies on all sorts of weather-related projects, including the instrument observations at a vast network of weather stations that provide basic data on climate.  


UNEP is the administrative umbrella for most major UN environmental efforts, including those on climate change. UNITED NATIONS ENVIRONMENT PROGRAMME

Autonomous Organisations in India against climate change :

Autonomous Organisations in India against climate change Govind Ballabh Pant Institute of Himalayan Environment & Development Indian Council of Forestry Research and Education Indian Institute of Forest Management Indian Plywood Industries Research and Training Institute Wildlife Institute of India
