Planetary Networks: Climate Change Flashcards
Tells the environmental condition in a specific place. It can be rainy, sunny, windy, or snowy
Weather
Describes the weather conditions expected in a particular place in a specific time of the year
Climate
Refers to the significant change in the average conditions of temperature and rainfall in a particular region over a long period of time.
Climate Change
What causes global climate change?
It is due primarily to the human use of fossil fuels that release dioxide and alternative greenhouse gases into the air (Water vapor, Carbon dioxide, Methane, Ozone, Nitrous oxide, Chlorofluorocarbons). These gases trap heat inside the atmosphere, which may have a variety of effects on ecosystems.
What are the effects of Climate Change?
- rising ocean levels
- severe weather events
- droughts that render landscapes additional vulnerable to wildfires
The process through which heat is trapped near Earth’s surface by substances known as greenhouse gases.
Greenhouse Effect
What are the six ways climate change will affect PH cities (according to Ranada, 2014)?
- More intense El Niño
- Sea surface temperatures to rise
- Tropical cyclones to intensify
- Sea levels to rise by 4-6 meters
- Rainfall, river flow, and flooding to intensify
This phenomenon occurs when the surface of ocean waters on the southern Pacific becomes abnormally warm
El Niño
By the end of the century, sea surface temperatures are expected to rise how many degrees Celsius?
1 to 4 degrees Celsius
What is an effect of the rising of sea surface temperature?
This can lead to more powerful storms because storms get their strength from heat rising from the sea.
What is the effect of the shift in the pH levels of our oceans?
- Widespread coral reef death
- Shrimps are not able to develop skins
- oyster cannot develop shells
- fish larvae may not be able to develop bones
(further endangering food security and the livelihood of fisherman)
What is the reason for the rising sea levels by 4 to 6 meters?
Scientists say this is due to the melting of ice sheets in northern portions of the globe like Antarctica and Greenland.
What is an effect of sea level rise to the Philippines?
This can submerge low-lying communities like Tacloban City which stands 3 meters above sea level
What and When was the strongest storm in recorded history?
Super Typhoon Yolanda (Haiyan) on Nov. 8, 2013 which devastated cities in the Visayas region
What is the effect of the intensification of rainfall, river flow, and flooding in PH cities?
It will be more difficult for agriculture and aquaculture sectors which are highly dependent on weather.
