SCI W6 Global Climate Phenomenon Flashcards
Refers to any significant change in the measure of climate lasting for an extended period of time.
Climate change
Refers to the recent and ongoing rise in global average temperature near Earth’s surface.
Global warming
Give me any 5 Main Indicators of Climate Change
Air temperature over land, Sea surface temperature over land, Air temperature over oceans, Sea level, Ocean heat, Humidity, Tropospheric temperature
What is the cause of climate change
Human expansion of the greenhouse effect.
the process through which heat is trapped near Earth’s surface by substance known as” greenhouse gases”.
Greenhouse effect
No life within the earth.
Greenhouse effect
gas in the atmosphere that absorbs and emits radiation within the thermal infrared range.
Greenhouse gas (GHG)
Without greenhouse gases the temperature on earth would be____
too cold to support life
With too much greenhouse gases it would ______
it would heat up beyond survivable levels.
What are the 5 gases responsible for 99.5 % of the greenhouse effect
Water Vapor (H2O), Carbon Dioxide (CO2), Methane (CH4), Nitrous oxide (N2O), Chlorofluorocarbon (CFC)
What are the Man made activities that contributes to atmosphere’s greenhouse gases
Burning fossil fuels, Releasing chemicals into the atmosphere, Reducing the amount of forest cover, Rapid expansion of farming, Development and industrial activities
What are the Natural sources contribute to atmosphere’s greenhouse gases
Forest fire, Vulcanic Eruption, Plants, animals and humans, Ocean
What are the effects of climate change
Rising temperature, Shrinking Ice Sheets, Sea level Rise, Biodiversity depletion, Ocean Acidification, Extreme Weather
Any actions focused to reduce the intensity of radiative forcing so as to lessen the effects of global warming.
Climate Change Mitigation
What are the ways to Mitigate the effects of climate Change
Increasing carbon sequestration and conservation, Use of Bioenergy, Reduced Fertilizer use, Anaerobic digestion of waste, Improved energy efficiency
