With one side portraying climate change as doomsday for the earth and the side calling it a load of hodgepodge, the science can sometimes get lost in the political debate. Both can quote that will back up their argument, which coupled with the media pressure to report both sides evenly causes confusion within the population. One thing that could help slightly clear the befuddlement is for the people to educate themselves on global warming science with primary sources (i.e. science papers). However, this is easier said than done. It would be extremely difficult for every person to read, much less comprehend, all scientific . For the average person, the style of writing and terminology can convolute the conclusions the reader was meant to grasp.
has to do with the rise in sea level, a consequence of increased emission of greenhouse gases (mainly CO2) in the atmosphere. this is a miniscule part of the body of climate change research, hey, I’m only one person.
The EPA has a explanation of why rising sea levels is detrimental to the earth. The IPCC has a more detailed explanation of the causes and effects of sea level rising. The figure below is from the IPCCC website .
This figure shows that sea levels have risen in the past and are projecting to dramatically increase over the next 100 years.
This study explores the correlation between CO2 increase and sea level rise. They use a 3D atmosphere-ocean general circulation model (AOGCM) to see how emissions affect peak sea level. Below are models that these and other scientists have used to sea level and surface temperature changes.
The conclusions from this study are as follows:
· Sea level changes depend not only on the cumulative emission of CO2 but also the time profile of emission. This means that the longer CO2 has been emitted the larger the sea level change. These scientists recommend that future policy should focus not only on reducing the cumulative CO2 emission, but also the rate of emission as well.
· Theoretically, sea level rise is reversible. Reducing and stabilizing emissions would halt and maybe reverse the sea level rise, but removing CO2 from the atmosphere would reverse it more quickly. This would require geoengineering technology which may have negative side effects
There are a few implications that these conclusions have on future negotiations. Countries should not only focus on their total CO2 emissions but also on their rate of emissions. Lowering the total level CO2 emitted, may not be enough to halt sea level rise. It also that geoengineering techniques should be explored more. According to the models, removing CO2 from the atmosphere will be an effective way in reversing sea level rise.

Hopefully, this of will clarify the science on one aspect of global warming. Rising sea levels a problem to CO2 emissions. The goal is that clear conclusions will allow the political debate to be more on the solution rather on the severity of the problem.
