Understanding my role in climate change and how it affects me

How does what I do today impact the future of our Earth?

Global Warming vs. Climate Change

"Global warming" describes an average temperature increase of the Earth over time.

"Climate change" describes how weather patterns will be affected around the globe. (includes temperature and how that

impacts the water cycle (ice melt, precipitation, and their impact on weather patterns)

What Causes Climate Change?

What’s the Big Deal with Carbon?

All living things on Earth have carbon in them

Carbon combines easily with other elements to form new compounds

What’s the Big Deal with Carbon?

When fossil fuels burn, we mostly get three things: heat, water, and CO2.

We also get some solid forms of carbon, like soot and grease.

All that carbon stored in all those plants and animals over hundreds of millions of years is getting pumped back into the atmosphere over just one or two hundred years

So, is carbon good or bad?

Carbon dioxide (CO2) is a greenhouse gas – so it helps trapheat close to Earth

So, its good….up to a point.

What are Greenhouse gases? Greenhouse gases are made out of:

Water vapor Carbon dioxide Methane (CH4) – Found in animal

waste & production in digestion, emitted from landfills as waste breaks down, emitted when natural gas and oil are burned

What are Greenhouse gases?

Nitrous oxide – (Nitrogen cycle) – emitted through agriculture, industrial process, wastewater management and fossil fuel consumption

What are Greenhouse gases? Ozone -- Ozone - (ground level) - Formed

when nitrogen oxides and VOC (volatile organic compounds) react in the presence of sunlight

Eg. VOC - Emissions from industries, electric utilities, motor vehicles, and chemical solvents

Chlorofluorocarbons (CFCs) - used to be used in aerosols, refrigerators, air conditioners, they are a VOC

Carbon footprint

The amount of greenhouse gases, especially carbon dioxide, emitted into the atmosphere by a person, company, country, etc activities.

What can I do to reduce carbon footprint?
