发帖数: 285 | 1 Over recent decades, average ocean temperatures on Earth have steadily
risen, causing the destruction of much marine habitant. It has been
established that the emission of greenhouse gases such as carbon dioxide
into the atmosphere can increase average ocean temperatures, and over the
past century the emission of carbon dioxide by human industry has increased
dramatically. Although many scientists believe that these emissions are
responsible for the increase in average ocean temperatures, geol | b*******g

not conclusive evidence. | h*s
发帖数: 48 | 3 1. Human activity/industry increase CO2 emission
2. increased CO2 increase ocean temperature
3. in the past, CO2 and Ocean Temp fluctuated widely w/o human intervention
from 1 & 2, --> human activity/industry responsible for ocean temp increase
from 3, if no human intervention, CO2 and ocean temp fluctuated widely,
could be both up and both down (positively correlated between CO2 level and
ocean temp), 3 tries to mislead you that CO2 level and ocean temp are not
related. 3 also tries to mislead
