Green House Gases trapping CO2 In And Raising Temperatures On Earth Drastically

  • What evidence supports that climate change is occurring?
    • The greenhouse gases are supposed to act like a blanket for Earth to keep us warm but, now it is a negative impact on the Earth. Greenhouse gases are trapping CO2 in which is creating more heat causing Global Warming. With today’s cars, machines and factories that are releasing tons of CO2 everyday, it’s not helping with our problem.
      • The Green Houses Gases are creating tons of problems. But the question is what are the evidences of this? Well, according to my research the evidences are:
        • Rise on Sea Levels: The rise in sea levels has gone up my much in the last century. This is caused by melting ice caps and glaciers but more due to the gases inside the sea. In the past decade, the sea level has doubled compared to the 20th century which rose only 1.6mm per year. The sea levels have rose about 6.7 inches in the last century. For every 1 meter the Sea rises, 10 meters of our shore is took away.
        • Shrinking Glaciers: The glaciers, particularly in Greenland and Antarctica, are decreasing because of gases which help maintain the temperature. The temperature has gotten so high that these huge ice glaciers and caps have begun to melt. Studies show that Greenland has lost 36-60 cubic miles (150-250 cubic kilometers) of ice EVERY YEAR between 2000 and 2006. Antarctica has lost about 36 cubic miles (152 cubic kilometers)

 

This graph shows us the Average Temperature Globally in Celsius. The graph ranges from 1860-2000. This clearly shows the rise of temperature from 1860-2000 and we can clearly see that it has raised quite a lot.  http://www.bbc.co.uk/schools/gcsebitesize/science/aqa_pre_2011/rocks/fuelsrev6.shtml

  • What are some natural causes of natural and human causes of climate change?
Natural Causes of Climate Change

 

Human Causes of Climate Change

 

·Volcanic Activity

·Solar Output

·Earth’s orbit around the Sun

·Changes in Solar Radiation

·Burning Fossil Fuels (Cars)

·Forestry

·Agriculture

·Factories

 

 

  • What are at least two consequences of climate change?
    • There are many consequences of Climate Change. The 2 I think that will affect us the most are:
      • Loss of Freshwater: The rise in the Sea Level means that the sea will extend to water estuaries and groundwater salinization areas. This will cause a drastic decrease of freshwater for not only us, humans, but also the ecosystem which lives in that area.
      • Loss of some Food Supply: The elevated CO2 levels, higher temperatures, and more precipitation in coastal areas have all decreased the crop yields. A study shows that for every 1 0C – 3 0C increase in temperature there will be less productivity for cereals, US soybeans, US maize, Indian wheat, Asian rice and African maize.

 

  • Record the Vital Signs measurements and describe/ summarize what is happening with each Vital Sign
    • Carbon Dioxide: 28ppm
      • The Carbon Dioxide level is proceeding at a high rate. It is very likely that is caused mostly by us, humans. It is coming to a rate which has been unprecedented in the past 1300 years.
      • Global Temperature: 87 0C
        • Most of the warming has occurred in the 1970s, the 20 most warmest years have occurred since 1981 and included the 10 warmest years occurring in the past 12 years. Temperatures continue to rise
      • Sea Ice Minimum:   4%/Decade
        • Has rapidly declined in the past several decades
      • Land Ice: 134 gigatonnes/year
        • Has decreased over the past 5 decades
      • Sea Level: 75 mm
        • The global sea level rose 17 cm (6.7 inches) in the last century. This is almost double to last century.

 

  • Do you believe that we should be concerned with climate change? Why or why not? What can we do to decrease the rate and impact of climate change?
    • I do think that we should be concerned with climate change because we are going to be the ones most affected by this. Our freshwater supplies will decrease which means less water for us, our food supply will go down which means that we will not have some of our favourite foods, animals that could interest or feed us could die which makes us lose, and the weather is too warm for and we could get seriously sick. We can use electric cars instead of burning fossil fuels, turn out our lights and small stuff like that. We can build items somewhere else than factories which cause more pollution and so on.

  1. Thank you Simran, I like your organization and the connections you’ve made to how climate change will affect us. More images could have been embedded into your post to more appealing to readers.
