Both speakers agree with this statement. Even Lurano, who thinks the research should wait until April or May, acknowledges the chance of snow melting. Lurano just thinks it’s less important than the researchers’ safety.

Neither speaker agrees with this. Even Jenkins, who is pushing to do the research no later than February, doesn’t say it will be impossible later. It’s just that there will be a risk the research won’t be successful.

Neither speaker agrees with this. Both acknowledge the risk that funding might be wasted, but neither Jenkins nor Lurano claims that the funding will certainly be wasted.

Both speakers agree with this statement. The disagreement isn’t about which months are coldest, it’s about whether the risk of wasting money or the risk to the researchers’ safety is more important.

Jenkins agrees with this statement, and Lurano disagrees, making this the point of disagreement. Jenkins thinks that not wasting money is the most important consideration, whereas Lurano thinks that the researchers’ safety should take priority.
