Answer:
Data from a wide range of time periods must be analyzed.
Step-by-step explanation:
The limitation to climate research that could easily be solved is that data from long periods of time can be analyzed. We can only gauge this based on history. So the earlier we can get super computers with greater capabilities, then the more likely it is that data from long period ranges can be analyzed. This would provide scientist with knowledge of the extent and prevention of global climate issues.
The other problems listed may not easily be solved compared to this.
