d collects as yard potentially such Materials that are ts as it trickles through wastes glass plastics, and c. perceived to be of harmful s Introduction of society that can pose a to human health energy into the hazard by of harmf d. Items that people discard yard plastics, and glass e. Water that collects contaminants as it trickles through wastes e from "Inconvenient Truth" Temperature and the concentration is closely related each other like as below grapgh. How we could measure CO2 and temperature for a 400 years ago? (0) CO2 Temp. E -10 400 350 300 250 200 150 100 50 Thousands of Years Before Present

Explanation / Answer

From the grapht, we can note that, 400 years ago, temperature variation was around -2oC from the average, that is temperature was decreasing by -2oC from the average temperature of 1000 of years. And the value of Carbon dioxide(CO2) was 300ppmv. This is 100ppmv less than the present CO2 concentration.
