Actually Bill, for the first time in recorded weather history, the temperature at the North Pole reached 0 degrees in 2016. There are signs of global warming everywhere. Melting permafrost in Arctic towns, less ice in the North West passage which makes vessel navigation safer and easier, etc. The question is how fast will the warming continue to happen and how severe will the impacts be. My personal take on all of this is it happens on a cyclical basis anyway but the effects are now being compounded by made made activities.
From a political perspective, easier access through the North West passage has heightened the interest in countries claiming ownership of those areas, US, Canada, Denmark, Russia, etc. Resource development, oil and gas, and another shipping route from East to West and vice versa are the main interests.
Climate change in the DR is a bit harder to gauge because of its location and existing climate. Hurricanes tend to be stronger now because of warmer ocean waters. Their frequency fluctuates from year to year. The Maldives and Seychelles are losing shoreline to higher tide levels. The DR is not experiencing this problem yet as far as I can tell. Some scientist say long periods of normal weather is abnormal and intermittent periods of abnormal weather is normal. No need to have a boat tied up by your house yet. It will be a long time before water is lapping at your door due to tidal range rise, if it ever happens.
