CLIMATE CHANGE

The amendment includes:

- New commitments for Annex I parties to the Kyoto Protocol who agreed to take on commitments in a second commitment period from 1 January 2013 to 31 December 2020 - A revised list of GHG to be reported on by Parties in the second commitment period - Amendments to several articles of the Kyoto Protocol

Kyoto Protocol

- Rio treaty led to the Kyoto Protocol of 1997 - took effect in 2005 - required 37 industrialized nations (plus the European Community) to reduce their emissions of greenhouse gases by 5.2 percent below 1990 levels in the period 2008-2012. - adopted on 11 December 1997 - entered into force on 16 February 2005 - there are 192 parties to the Kyoto Protocol - operationalizes the United Nations Framework Convention on Climate Change by committing industrialized countries and economies in transition to limit and reduce greenhouse gases (GHG) emissions in accordance with agreed individual targets.

Flourinated gases

- created as replacements for ozone depleting refrigerants but have proved to be both extremely warming GHGs. - have no natural sources but are entirely man-made. - GWPs range from 1,800 to 8,000 and some variants top 10,000.

Zoning

- influence settlement patterns and the design of communities, the size and type of housing, and transportation choices that produce lower greenhouse gas emissions. - Zoning ordinances can help shape and locate redevelopment and new residential and commercial projects to promote more compact development that saves on energy.

CO2 or Carbon dioxide

- produced any time something is burned - most common GHG, constituting by some measures almost 55% of total long-term GHGs - Carbon dioxide is assigned a GWP or Global Warming Potential of 1.

Methane or CH4

- produced in many combustion processes and also by anaerobic decomposition. - for example: in flooded rice paddies, pig and cow stomachs, and pig manure ponds. - breaks down in approximately 10 years, but is a precursor of ozone, itself an important GHG. - CH4 has a GWP of 28-36.

Black Carbon (BC)

- tiny particles of carbon released as a result of the incomplete combustion of fossil fuels, biofuels and biomass. - particles are extremely small, ranging from 10 micrometers - Small enough to pass through the walls of the human lung and into the bloodstream. - BC is considered the second biggest contributor to global warming after CO2.

Sulphur hexafluoride or SF6

- used for specialized medical procedures, but primarily in what are called dielectric materials, especially dielectric liquids. - used as insulators in high voltage applications such as transformers and grid switching gears. - last thousands of years in the upper atmosphere. - GWP of 22,800.

Fluorinated gases (hydrofluorocarbons and perfluorocarbons) are _______________________ as potent a greenhouse gas as CO2.

10 Things You Can Do to Reduce Greenhouse Gases

1. Drive less 2. Recycle bottles, cans, and paper. 3. Use less hot water by taking short showers and washing clothes in cold water. 4. Replace incandescent light bulbs with compact fluorescence bulbs. 5. Turn off appliances and unplug them. 6. Buy Energy Star appliances 7. Eat locally grown, organic food 8. Avoid heavily packaged foods 9. Buy recycled paper products 10. Fly less

THREE POSITIONS ON GLOBAL WARMING

1. global warming is not occurring and so neither is climate change 2. global warming and climate change are occurring, but these are natural, cyclic events unrelated to human activity 3. global warming is occurring as a result primarily of human activity and so climate change is also the result of human activity.

GLOBAL CLIMATE

The connected system of sun, earth and oceans, wind, rain and snow, forests, deserts and savannas, and everything people do.

GLOBAL WARMING

The slow increase in the average temperature of the earth's atmosphere because an increased amount of the energy (heat) striking the earth from the sun is being trapped in the atmosphere and not radiated out into space.

The global climate is more than the "________________" of the climates of specific places.

average

Particulates, also known as ____________________ or soot, trap heat in the atmosphere and contribute to climate change.

black carbon; soot

Climate Change

change in climate that can be identified by changes in the mean and/or variability of its properties and that persists for an extended period.

Without our atmospheric greenhouse the earth would be very __________. ________________, however, is the equivalent of a _____________ with high efficiency reflective glass installed the wrong way around.

cold; Global warming; greenhouse; reflective glass

United Nations Framework Convention on Climate Change

environmental treaty signed in Rio de Janeiro in 1992 that stated a concern that "human activities have been substantially increasing the atmospheric concentrations of greenhouse gases, that these increases enhance the natural greenhouse effect, and that this will result on average in an additional warming of the Earth's surface and atmosphere and may adversely affect natural ecosystems and humankind."

One important element of the Kyoto Protocol was the establishment of ____________ ____________ _____________, which are based on the trade of emissions permits.

Nitrous oxide

- (laughing gas) - NO/N2O or simply Nox - a byproduct of fertilizer production and use, other industrial processes and the combustion of certain materials. - Nitrous oxide lasts a very long time in the atmosphere, at the 100-year point of comparison to CO2. - its GWP is 265-298.
