Climate Change

Question 1

Quaternary period evidence

Answer 1

Oxygen trapped in layers of ocean sediments

Question 2

Recent evidence of climate change

Answer 2

Glaciers melting-

Rising sea levels

Seasonal changes-

Question 3

Natural causes for climate change

Answer 3

Orbital changes- Cylcle Milankovitch Eccentricity Axial Tilt Precision

Solar activity - sunspots max to mini

Volcanic activity -ash can block sun cooling temps in Earth.

Question 4

Human causes for climate change

Answer 4

Burning fossil fuels Co2 emission
-Deforestation burning of wood

Methane emission- decaying of organic matter I.e landfill site
Farme live stock

Question 5

How to manage climate change

Answer 5

Planting trees - act as carbon sinks remove Co2 from atmosphere
Provide moisture to atmosphere adding more clouds

International agreements-
Many governments negotiate to make a more sustainable future I.e Paris Agreement

Carbon Capture-technology used to store Carbon
Once captured Co2 is put in long-term storage

Question 6

How to adapt to Climate Change

Answer 6

Agriculture adaptation-climate change affects agriculture system
Farmers need to PLANT TREES to SHADE Seedlings
Introduce DROUGHT-RESISTANT strains of CROPS
New CROPPING PATTERNS introduced

Question 7

How to adapt to Climate Change 2

Answer 7

Reducing risk of sea levels
Rising sea levels will threaten agricultural land
Increase coastal erosion

To stop this- Building Houses that are raised off ground on Stilts
Population could be relocated
Construction of SEAWALLS with SANDBAGS
