    I agree with UGO….. gradual cooling.

    The surface stations that have been used for years are mis-reporting global temperatures due to poor placement and maintenance.

    Urban encroachment is causing higher than actual temperatures to be recorded….. and it is gradually getting worse as man builds farther and farther out.

    NO joke!
    **** ice is melting equal to Texas and Alaska combine! *****

    Think about it when it melt , it has to go somewhere so we have flood worldwide and worst every year

    I would say erratic cooling but the term erratic is subjective
    Here is 5 million years.

    Much of the recent cooling (last 3 million years) is probably due to geologic factors such as continents closing in on the north pole, closing of the Isthmus of Panama, rise of the Himalaya, creation of the Indonesian Archipelago
    Hre is a graph which shows mostly cooling in the Cenozoic Era for the last 65 million years. Just remember that now is toward the left on the graph.

    Rapid cooling. If you look at global temperature graphs.

    None of the above, the correct answer is gradual cooling.
