Climate change Flashcards
Physical causes of climate change
-sunspots
-melting permafrost
-milankovitchs theory
-volcanic euriptioms
-changes in the tilt of the Earth
Human causes of climate change
-fossil fuels
-deforestation
-using transportation
-fridges omit cfs
-industrialisation
nitrous oxodes are released from vechicle exausts and power stations
increase in realesinf of pollutants fro, traffic wnd rubbisj such as co2 nitrous oxides and cfs
How does deforestation cause climate change?
Less trees to soak up co2
How does burning fossil fuels cause climate change?
releases greenhouse gases, primarily carbon dioxide, into the atmosphere, trapping heat and causing the planet to warm, leading to climate change.
How does using transportation contribute to climate change?
Cars significantly contribute to climate change by emitting greenhouse gases, primarily carbon dioxide (CO2), during fuel combustion, which traps heat in the atmosphere and leads to global warming.
How does volcanic eruptions affect climate change?
by injecting gases and particles into the atmosphere
Releasing sulphur dioxide
How do sunspots Impact climate change?
When sunspots are abundant, the Sun emits more energy, potentially leading to warmer temperatures on Earth.
Impacts of climate change
-Melting ice caps cause sea level rises, low lying countries at risk eg Bangladesh
-crops can be affected as farmers can’t prepare for the changes
-milder winters and wetter summers
-increase in desertification and deforestation
-increase in extent if tropical diseases
-changes in atmospheric patterns that link to monsoons such as el nino and La Niña
-melting permafrost can lead to release of harmful gases and unstable infrastructure
Responses to climate change
- legal measures in countries such as Brazil to protect rainforests
- people being encouraged to walk or cycle
- ‘reduce reuse recycle ♻️’
- the river Thames flood barrier
- government policies “ helping households to cut their energy bills”
