Climate change Flashcards
(25 cards)
What human factors of climate change
fossils fuels , agriculture and deforestation
what are the physical factors of climate change
orbital changes , solar output and volcanic activity
how does fossil fuels cause climate change
burning fossil fuels releases carbon dioxide contribute to enhancing greenhouse gas effect
how does agriculture cause climate change
larger populations demand for meat and animal grazing releases methane into atmosphere
how does deforestation contribute to climate change
logging increases co2 as less photosynthesis occur
how does volcanic activity account to climate change
volcanic gasses and ashes cover sunlight so reducing global temperature acts as cooling effect
how does solar output contribute to climate change
sunspots increase every 11 years fewer sunspots in coldest periods
how does orbital changes contribute to climate change
changes in which the earth orbits the sun changes affecting where sun hits earth and how intense the sun is which controls seasons
suggest the four evidences for climate change
- increase in temp by 1 degree every year
- glaciers melting due to increase temperatures
- rising sea levels by 19cm since 1900
- warm ocean temperatures

what does increased temperature suggest to a persons health
can cause diseases such as skin cancer
how does climate change make difficulties for farmers
decreases crop yield and require more irrigation
what do droughts causes by climate change pose
reduce food and water supplies , water scarcity in southeast UK
what does increase flood risk cause
repair cost and insurance cost
how does low rainfall by climate cause problems
food shortages
what does sea level rising by climate changes mean
coastal erosion and flooding
what are the two ways of managing climate change
mitigation and adaptation
what are the 4 ways of mitigating climate change
afforestation , alternative energy produce , carbon capture and international agreements
explain alternatives of fossil fuels and why fossil fuels are bad
fossil fuels emit greenhouse gas and contribute to global warming therefore using tidal/wind/solar energy , hydro-electrical , nuclear power and geothermal we can prevent this
explain carbon capture
capturing carbon dioxide and storing it underground - 90% of industry emissions can be stored like this
explain afforestation
planting trees store carbon dioxide due to photosynthesis and release moisture producing clouds which absorb solar radiation
benefits to international agreements
agreements to agree on reducing emissions and create a substantial society
name the three adaptations of climate change
managing sea levels rising , change agricultural methods and manage water supply
how can we adapt to sea levels rising
implement coast defences , houses built on stilts so they are raised above ground , designating areas that cant be used for living , bunds to slow down water flow and trap sediment
