In a new paper (Stein et al., 2017), scientists find that Arctic sea ice retreat and advance is modulated by variations in solar activity.
In addition, the sea ice cover during the last century has only slightly retreated from the extent reached during coldest centuries of the Little Ice Age (1600s to 1800s AD), which had the highest sea ice cover of the last 10,000 years and flirted with excursions into year-round sea ice.
The Medieval Warm Period sea ice record (~900 to 1200 AD) had the lowest coverage since the Roman era ~2,000 years ago.
I know everyone is going to focus on the little blip (or not) at the end which either does or does not show Arctic ice is currently melting, but what I find interesting is that the amount of sea ice appears to have been increasing for the last 2000 years.
The irony of course, is why on earth would anyone want to continue the trend shown in the last 2000 years and head into an ice-age. Indeed, if it weren’t for the lies from eco-activists and if most people sat down rationally to think about it, we’d all be trying to work out a plan to stop us going into another ice age.
The same is also true with levels of CO2. During the ice-ages, CO2 levels fall to a dangerously low levels below which it is doubtful many plant species could survive. This means there is a plausible scenario that live on earth as we know it may cease during a future ice-age when (without human intervention) CO2 levels could plumet below the level at which most plants … and therefore most animals … could survive.
If I were even mildly tempted into religious beliefs … I could quite easily believe there was some god being who deliberately evolved humans to save the earth from an icy doom by releasing all that locked up CO2.
