If the presence in greenhouse gases in earth's atmosphere continues to increase at the present rate, scientists predict that in the next 50 to 100 years, atmospheric temperatures could rise by 2oc. all of these could be consequences of global warming except

Had to look for the options and here is my answer.

Given that the present rate of greenhouse gases in Earth's atmosphere is continuously rising, it has already been predicted by scientists that there could be a rise of 2 degrees celsius in the next 50 to 100 years. Based on the listed ones, all could be the result of global warming except for "an increase in square miles of polar ice covering Earth." Hope this helps.

The rate that would change would be the  searching efficiency/attack rate. there are only two other rates in this model: the  growth rate of prey, and the  predator or consumer mortality rate.the  searching efficiency/attack rate is what indicates how effectively can a predator capture its prey whether in the searching process or actual capturing/attacking process.
