And a couple of years ago a team that set off to sail across the arctic in the summer months expected to have difficulty; the same difficulty they had two years previous. They had to turn back because of a preponderance of ice.
Well, that didn't happen on their second trip. There was so little ice in the same areas that they sailed across with no difficulty.
Global climate change is the more accurate term for the increasingly devastating climate phenomenon affecting the planet.
Average temperatures are rising relatively steadily, albeit marginally (1-2 degrees over the course of a few decades, doesn't sound too impressive).
What that actually masks is the increasing deviation from the norm in localized areas; some areas get colder, some areas get hotter. Either way, weather systems become severely disrupted globally, and has a lot of widescale consequences; ranging from crop viability (hello, not been able to feed hundreds of millions of people), to the ability of some areas to hold ice (i.e. greenland, dumping shelfs of ice into the atlantic, reducing its salinity significantly (as in significant enough to cause a large-scale affect), causing the freezing point of water to go up, or temperature cycling systems that exist from large scale pressure differentials to disappear, causing a whole host of other side affects. The variance of temperature also increases as well; which means we get less consistent weather patterns, more cold snaps (which again reduces crop viability), and more uncomfortably hot days, etc.
In combination with a planet that's already been stretched to provide the odd 6 billion of us with adequate resources to maintain our current and increasing standard of living (and the accompanying increase in resource usage), and none of these changes are what we'd call good news.
It's only surface temperatures that are increasing, and that can largely be attributed to the heat island effect. The troposphere, where any greenhouse warming would be most prevalent, is not warming the way it should be based on the 'global warming' hysteria.
The global warming/climate change movement is political in nature. It wasn't originally, but it's morphed into something that no longer has anything to do with actual science.

Exactly, this is what I've been saying for some years now. I don't necessarily like the terminology they've given this present global catastrophy. There are so many other variables to describe what is going on here. I simply call it Global Ruin.
You're right about areas of colder than normal temps and areas of warmer than normal temps. Friends in South Africa have told me winter is colder there now and seems to last longer. Other friends from Australia have said the same for their part of the world. Look at some of those strange rare snowfalls in Sydney. Then I read something about of all the world's Glaciers, the ones in the Andes don't seem to be retreating, some even advancing.
So northern hemisphere warmer, southern hemisphere colder and equatorial regions experiencing more violent extreme storms on a regular basis than in times past. Bottom line is that all of mankind is at fault for this global ruin. The big three most reprehensible, government , big business (including science) and religion. Many scientists have some ideas for correcting things, but realize they are only stop gap measures. Even if there are the primo ideas for correcting things, there is no guarantee that they can get everyone to climb on board and get with the program.
