Description
Considering the reading material you have reviewed and class information, state whether you believe either Natural Climate Variability or Greenhouse Gas Emissions (CO2) may be responsible for the reduction in Arctic Sea Ice levels overall. If you’re undecided, then state your reasoning for that position as well.
Your journal entry should have complete sentences in length and be based on scientific reasoning and/or data. Make sure you state any of these you base your reasoning on in your entry.
