Skipping the "Global Warming" argument all together the Earth very much in a cold spell in the palaeontological sense[0]. It has been much, much warmer for very long periods of time and really only slightly colder. We're far closer to another ice age than we are to the long term average temperature of the planet, let alone its normal maximum temperature. Generally, the warmer periods have given rise to large ecological growth. Maybe human's won't like it, but consider the amount of diversity that would exist with a near rain forest climate across nearly the entire earth.
