Answer 2

It's D. They've happened quite often in the past, and will occur again in the future. It's impossible to cover absolutely everything with ice.

Answer 3

nicely of direction there will be yet another ice age - have not you seen The Day After the next day? That became into needless to say nicely researched and in line with best predictions. To complicated slightly further, yet another ice age is very probable. Geologists in no way agree on something (consisting of ways the dinosaurs disappeared), yet many think of that there have been circumstances interior the previous whilst the entire earth became into buried in ice sheet kilometers thick, and circumstances whilst there became into not a single snow flake on the north pole. The final considerable ice age ended approximately 10,000 years in the past, on condition that whilst it rather is been getting frequently warmer yet with chilly 'blips'. the main recent super one became into approximately 2 hundred years in the past, whilst it became into chilly sufficient for cows to be roasted on the frozen River Thames (London, uk). it form of feels extremely probable that we would desire to constantly be getting chillier returned interior the subsequent 500 years or so. yet in line with possibility not. the recent 'international warming' would or would possibly not heavily impact the organic cycles. despite if it does there is not something to characterize that it will certainly convey approximately a warming of the entire planet - fairly the alternative, rather. the warmth sea currents that flow from the Altantic equator to the north pole can provide up, which might convey approximately a considerable cooling of the northern hemisphere. in all probability. would we live to tell the story as a species? it form of feels probable, in spite of the reality that if the earth grew to alter into lined in ice sheets returned it ought to show complicated, quite for every physique making freezers for a dwelling.

Answer 5

I choose C.
