climate change

• change in the usual weather found in a place. can also be defined as a change in earth’s climate

causes of climate change

• green house gases

• human activites

• solar irradiance

• green house gases

• certain gases in the atmosphere block the heat from escaping

• human activites

• there’s more than 95% probabilty that the industrial activities of humans over tge past 50 years have warmed our planet

• solar irradiance

• changes in the sun’s energy output would cause the climate to change

effects of consumption patterns to climate change

• household consumption forms an important of the production-consumption chain

• billions of households around the world combined are a major contributor to environmental problems such as climate change, air and water pollution, land use, and waste segregation

• energy, materials, and resources we use have direct and indirect impacts on the environment. generally, indirect environmental effects of consumption are higher than the direct ones

Effects of Climate Change

1. Temperatures will continue to rise

2. Changes in precipitation patterns

3. More droughts and heat waves

4. Strength and intensity of typhoons and hurricanes
will increase

5. Rise of sea level by one (1) to four (4) feet by 2100

6. Ocean acidification

steps to address the problems of climate change

1. mitigation and adaptation approaches

2. what can we do to help address climate change?

1. mitigation and adaptation approaches

• migitating climate change means reducing the impacts of climate change

• to do this, the UN intergovernmental panel on climate change requires the following;
  
  

  (1) prevention of hazardous human intervention with the climate system

  
  

  (2) stabilization of green house gsa levels based on a time frame that would allow ecosystems to adapt to climate change

adaptation

• adapting to life in a changing climate, involves adjusting to actual or expected future climate

2. what can we do to help address climate change?

a. at home

b. at the office

c. on the road

a. at home

• change the light bults

  • choose light emitting diode and compact fluorescent lamps

• reduce, reuse, and recucly

  • use of eco bag

• use water efficiently

  • heating, pumping, and treating water use a lot of energy and because of this, save water consumption to reduce greenhouse gas of emissions

• practice composting

  • composting helps to reduce the amount of garbage sent to landfills by converting food and yard waste into natural fertilizers

b. at the office

• manage your office equipment energy wisely

  • save energy

  • unplug power cords

  • turn off equipment and lights at the end of the day

• learn to commute

  • use of public transportation, carpooling or biking

• reduce, reuse, recycle

  • recycle papers and use them as scratch papers

c. on the road

• buy a fuel-efficient and low greenhouse has vehice

• drive smart

  • go easy on the breaks and gas pedal, avoid hard accelerations, lessen your time idling, and remove unnecessary items in your trunk to reduce weight

• ensure proper car maintenance

  • regular tune ups and follow cars maintenance schedule

• check tires regularly

  • check your tire pressure regularly, cars with under-inflated tires increase tire wear and reduce car’s fuel economy

• use renewable fuels

  • use renewable fuels and green fuels for your car to help reduce greenhouse gas emissions and air pollution
