Climate Change Flashcards
What causes Greenhouse Warming?
Unprecedented release of CO2 in the atmosphere due to human activities
When was the rapid increase of CO2 concentration marked?
The rapid increase has been occurring since the onset of industrialization. It followed the increase of CO2 emission from the burning of fossil fuels.
What is climate change?
- a present and future threat to modern humans
Examples of typhoons
- Super Typhoon Haima (Lawin) 2016
- Hurricane Irma
- Typhoon Ondoy 2009
- Typhoon Haiyan 2013 [DEADLIEST]
If from atlantic = ? ; If from Pacific = ?
Atlantic = Hurricane
Pacific = Typhoon
Strongest storm recorded at landfall
Typhoon haiyan - 2013
Strom Surge Characteristics
When there are typhoons (windspeed is strong), strong winds causes waves to interact with bottom (Reduces speed; Increases Height)
Explain Climate
Climate is the average conditions and changes (patterns) in the atmosphere over a LONG SPAN OF TIME in a locality or region
- 30 year average weather pattern
Explain Weather
average conditions and changes (patterns) in the atmosphere over a SHORT SPAN OF TIME in a locality or region
- Daily atmospheric conditions
How is “span of time measured”
30 year patterns
1st Trend of Climate change
- Mean global surface temp. has increased by about 0.3 to 0.6 degrees celsius since the late 19th century
Why are small degree changes in the climate important?
If you project it to a hundred years, the temperature rise will become worse
2nd Trend of Climate change
Atmospheric concentrations of CO2 are increasing. The mean concentration of approximately 316 parts per million per volume (ppmv) in 1958 rose to approximately 369 ppmv in 1998
- it drops and increases due to seasonal changes
What is important about the 1860s?
The start of Industrial revolution - start of burning coal
The Twin evil of global warming
Ocean acidity - since the ocean also absorbs CO2, too much causes stress to marine life
