A seemingly simple question heading to the end of 2012:
What were the most notable climate-related stories of the year?
A group led by Greg Laden,
interested in climate science, put together a list of notable, often, most worrying, climate-related stories of the year, along with a few links that will allow you to explore the stories in more detail. While it started, perhaps innocently, as a quest for a 'top ten' list, the effort to fit within an arbitrary limit quickly fell by the wayside. Thus, we did not try to make this a “top ten” list, because it is rather silly to fit the news, or the science, or the stuff the Earth does in a given year into an arbitrary number of events. (What if we had 12 fingers, and “10” was equal to 6+6? Then there would always be 12 things, not 10, on everyone’s list. Makes no sense.) We ended up with 18 items, but note that some of these things are related to each other in a way that would allow us to lump them or split them in different ways. (See this post by Joe Romm
for a more integrated approach to the year’s events. Also, see what Jeff Masters did here
.) We only included one non-climate (but related) item to illustrate the larger number of social, cultural, and political things that happened this year. For instance, because of some of the things on this list, Americans are more likely than they were in previous years to accept the possibility that science has something to say about the Earth’s climate and the changes we have experienced or that
may be in the future; journalists are starting to take a new look at their own misplaced “objective” stance as well. Also, more politicians are starting to run for office on a pro-science pro-environment platform than has been the case for quite some time.
A failing of this list is that although non-US based people contributed, and it is somewhat global in its scope, it is a bit American based. This is partly because a few of the big stories happened here this year, but also, because the underlying theme really is the realization that climate change is not something of the future, but rather, something of the present, and key lessons learned in that important area of study happened in the American West (fires) the South and Midwest (droughts, crop failures, closing of river ways) and Northeast (Sandy). But many of the items listed here were indeed global, such as extreme heat and extreme cold caused by meteorological changes linked to warming, and of course, drought is widespread.
This list is subject to change, because you are welcome to add suggestions for other stories or for links pertaining to those already listed. Also, the year is not over yet. Anything can happen in the next few days!

Note that even among this extensive list, while the most serious 'challenge' is the U.S.-centric nature of the list/discussion, here are two examples of serious 'missing' items:
1. Amid massive climate-chaos related issues in the United States (hint, see after the fold), the 2012 Presidential campaign operated under a cloud of 'Climate Silence', with what could be described as a conspiracy between 'The Village' (the traditional media) and the political elite to downplay (actually, basically ignore) the mounting urgency of doing something to avoid hurtling over the Climate Cliff. And, as a corollary to this, Republican Party climate denial continues apace (with serious impact on U.S. government (at Federal, State, and Local levels) even as a growing share of the American public links extreme weather issues with climate disruption.
2. Trees, globally, seem to be suffering seriously from direct and indirect impacts from pollution. While people have noticed trees downed by Sandy, the Derecho, dying amid drought, there has been far too little notice of just how unhealthy a huge number of these trees were that made them susceptible to falling. See Wit's End for a focus on this.
E.g., the long list that comes after the fold is far from a fully robust list of the notable 2012 climate events and issues.
1 Super Storm Sandy
Super Storm Sandy, a hybrid of Hurricane Sandy (and very much a true hurricane up to and beyond its landfall in the Greater New York/New Jersey area) was an important event for several reasons. First, the size and strength of the storm bore the hallmarks of global warming enhancement. Second, its very unusual trajectory was caused by a climatic configuration that was almost certainly the result of global warming. The storm would likely not have been as big and powerful as it was, nor would it have likely struck land where it did were it not for the extra greenhouse gasses released by humans over the last century and a half or so.
A third reason Sandy was important is the high storm surge that caused unprecedented and deadly flooding in New York and New Jersey. This surge was made worse by significant global warming caused sea level rise. Sea level rise has been eating away at the coasts for years and has probably caused a lot of flooding that otherwise would not have happened, but this is the first time a major event widely noticed by the mainstream media (even FOX news) involving sea level rise killed a lot of people and did a lot of damage. Fourth, Sandy was an event, but Sandy might also be the “type specimen” for a new kind of storm. It is almost certainly true that global warming Enhanced storms like Sandy will occur more frequently in the future than in the past, but how much more often is not yet known. We will probably have to find out the hard way.
Note that the first few of the links below are to blog posts written by concerned climate scientists, whom the climate change denialists call “alarmists.” You will note that these scientists and writers were saying alarming things as the storm approached. You will also note that what actually happened when Sandy struck was much worse than any of these “alarmists” predicted in one way or another, in some cases, in several ways. This then, is the fifth reason that Sandy is important: The Earth’s weather system (quite unconsciously of course) opened a big huge can of “I told you so” on the climate science denialist world. Sandy washed away many lives, a great deal of property and quite a bit of shoreline. Sandy also washed away a huge portion of what remained of the credibility of the climate science denialist lobby.

We also increasingly recognized that loss of Arctic sea ice affects Northern Hemisphere weather patterns, including severe cold outbreaks and storm tracks. This sea ice loss is what set up the weather pattern mentioned above that steered Sandy into the US Northeast, as well as extreme cold last winter in other areas.
Arctic Warming is Altering Weather Patterns, Study Shows
5 and 6 Two major melting events happened in Greenland this summer.
First, the total amount of ice that has melted off this huge continental glacier reached a record high, with evidence that the rate of melting is not only high, but much higher than predicted or expected. This is especially worrying because the models climatologists use to predict ice melting are being proven too optimistic. Second, and less important but still rather spectacular, was the melting of virtually every square inch of the surface of this ice sheet over a short period of a few days during the hottest part of the summer, a phenomenon observed every few hundred years but nevertheless an ominous event considering that it happened just as the aforementioned record ice mass loss was being observed and measured.

Also, this information is just being reported and we await further evaluation. As summer begins to develop in the Southern Hemisphere, there may be record warmth there in Antarctica. That story will likely be part of next year’s roundup of climate-related woes.
8 More Greenhouse Gasses than Ever
Even though the rate of emissions of greenhouse gasses slowed down temporarily for some regions of the world, those gasses stay in the air after they are released, so this year greenhouse gas levels reached new record high levels

A very rare event caused by drought conditions was the closing of the Mississippi River to traffic in mid-summer at two locations. This is part of a larger and growing problem involving drought, increased demands for water, and the importance of river traffic. Expect to hear more about this over the next couple of years.

Many of us who contributed to this list feel that this is potentially the most important of all of the stories, partly because it ties together several other events. Also, it may be that a change in the air currents caused by global warming represents a fundamental yet poorly understood shift in climate patterns. The steering of Hurricane Sandy into the New York and New Jersey metro areas, the extreme killer cold in Eastern Europe and Russia, the “year without a Spring” and the very mild winters, dome of the features of drought, and other effects may be “the new normal” owing to a basic shift in how air currents are set up in a high-CO2 world. This December, as we compile this list, this effect has caused extreme cold in Eastern Europe and Russia as well as floods in the UK and unusually warm conditions in France. As of this writing well over 200 people have died in the Ukraine, Poland and Russia from cold conditions. As an ongoing and developing story we are including it provisionally on this list. Two blog posts from midyear of 2011 and 2012 (this one
and this one
) cover some of this.

19 The first climate denial “think” tank to implode as a result of global warming…
… suffered major damage this year. The Heartland Institute, which worked for many years to prove that cigarette smoking was not bad for you, got caught red handed trying to fund an effort explicitly (but secretly) designed to damage science education in public schools. Once caught, they tried to distract attention by equating people who thought the climate science on global warming is based on facts and is not a fraud with well-known serial killers, using large ugly billboards. A large number of Heartland Institute donors backed off after this fiasco and their credibility tanked in the basement. As a result, the Heartland Institute, which never was really that big, is now no longer a factor in the climate change discussion. [Note: This ending sentence is/was Greg's.
Sadly, I don't think it is true. We (the progressive community, including Daily Kos ...) failed to drive the wooden stake through Heartland's heart when it was down. While Heartland has lost much of their funding and Corporate support
