Please answer the following Q10, Q11, Q12 and Q13 according to the graphs, thanks.
405 400 395 Now, you will be looking at number of E 39 climate indicators to learn about changes in the Earth's climate. We first start with Carbon Dioxide- the culprit- in-chief). Q10. The graph on the right shows Carbon Dioxide concentrations in the atmosphere are steadily increasing. In 2005, CO2 was 380 PPM, which increased to 400 PPM by 2015. Based on these two data points, calculate the annual rate of CO2 increase over this interval? 385 380 375 2007 2009 2011 2013 2015 YEAR Q11. Assuming this rate remains constant over the next few decades, years, what will be the CO2 concentrations in the year 2050 AD Let's look at how the 'Sea Level' is changing. Sea level has been rising over the past century, and the rate has accelerated in recent decades due to a combination of melting glaciers and ice sheets, and thermal expansion of seawater as it warms [note: melting of sea ice does not contribute to increase in sea level...just like melting of ice cubes in a glass filled to the brim will not spill water]. The chart below shows that the sea level is rising at a rate of 3.20 mm/ year (about an eighth of an inch) since 1993 AD (right panel). This information is based on satellite observations. The left panel shows sea level change between year 1870 and 2000 as measured by tide gauges across the globe Q12. Use the left panel to calculate the average rate of annual increase in sea level between 1870 and 2000? Select the response on BB that matches your answer Q13. Use the rate of sea level rise from the right panel-3.20 mm/year, to calculate the expected increase in the sea level (i.e., above the 2015 AD level) by the year 2100 ADExplanation / Answer
Q10. Annual rate of CO2 increase over 2005- 2015 interval = (400-380)/10 = +2 ppm.
?Q11. The CO2 concentration in the year 2050 AD = 400 + (2050-2015)*2 = 470 ppm.
?Q12. The annual rate of increase in sea level = 200/130 = +1.54 mm/year.
?Q13. Expected increase = 3.20* 85 = 272 mm by the year 2100 AD. Therefore, the sea level will reach to = 60+ 272 = 332 mm.
