Topic 2- Climate Change Flashcards
What evidence is there that the global climate is changing?
The seas are rising and the Earth’s average temperature is rising. This can be proved from many graphs that show the difference in temperature over the years
Would we be able to live in a world without greenhouse gasses
No living creature would survive the low temperatures
How have humans altered the carbon cycle?
Humans have altered the carbon cycle by making more carbon go into the atmosphere and therefore making the atmosphere thicker
What are the stages of the greenhouse effect?
- The sun’s rays pass through the atmosphere to Earth 2. The Earth’s surface is warmed 3. Heat is reflected from the Earth back out to the atmosphere 4. Some heat escapes into space 5. Burning fossil fuels and cutting trees increase the Carbon Dioxide levels 6. Some heat is trapped by Carbon Dioxide and other greenhouse gasses 7. So the atmosphere gets warmer.
What are some of the causes of climate change?
Deforestation (more CO2 in the air), carbon being emitted into the air, heat is trapped by greenhouse gasses, carbon is dug up or retrieved from the oceans just to be consumed, thick atmosphere,
Who and what is to blame for Climate Change?
People in rich countries emit the most greenhouse gasses, humans in general emit every time they use electricity or drive in their cars.
Why are sea levels rising?
Glaciers on land are melting into the sea, rising its sea level.
What is Climate Change?
Climate Change is the fact that our climate on the Earth is changing compared to years earlier
What are the consequences of Climate Change?
Coastal areas that are very close to the sea’s surface could get flooded over time. An estimated 17 million people in Bangladesh will be affected by climate change. Also, the rising in temperature will cause more tropical storms to happen as the sea’s temperature gets warmer
What can be done to prevent Climate Change?
By getting electricity from sources other than burning fuels, we can reduce the carbon emissions in the air.
What can be done to make our houses more sustainable?
Insulation in walls, roof, and floor; build homes facing south; use solar panels for electricity; use electric cars; find work close to where you live; like BedZED, find all materials for the house within a certain range of the house.
Pros for generating renewable energy?
Pros:
No greenhouse gas emissions, renewable, eco-friendly, generators could last up to 30-40 years, can get energy from many different natural energies, helps wildlife evolve with human changes and adapt to urbanisation
What is the carbon cycle?
The carbon cycle is the process in which carbon travels from the atmosphere into organisms and the Earth and then back into the atmosphere.
How is the greenhouse gas affect increasing?
As more and more greenhouse gases create a bigger barrier, it is stopping more and more of the suns rays from escaping into space, therefore heating up the planet too quickly.
Cons for creating renewable energy?
Cons:
Lots of maintenance required, if there are malfunctions, there could be some pollution, can disrupt animal migration, could impact animals’ lifestyles, the spinning blades could kill wildlife from tidal and wind energy, not always reliable and do not always work in all seasons.
