How global warming spoiled the Snowquester

Just a few degrees was the difference between bare ground and a winter wonderland in D.C.’s urban core last week. Would the storm, which was a disappointment to so many Washingtonian snow lovers, have played out differently had it occurred 100 years ago? Historical data say yes.

Could a quiet sun cancel global warming?

The current solar maximum, the high point in the sun’s activity over an 11-year cycle, is the lowest in over 100 years NASA says. Scientists speculate solar activity may decline further in the coming decades. Could a quieting sun cause the climate to cool enough to stall or even reverse global warming from the build-up of greenhouse gases? Leading climate scientists say no, the effect of the sun is too small.

Winter warming accelerates in Maryland and Virginia since 1970

Prior to 1970, temperatures in Maryland and Virginia had been more or less flat over the course of the 20th century. But since that time, they have climbed sharply, warming about 2.5 degrees F - part of an abrupt steepening in the rise of nationwide winter temperatures.

In the wake of punishing heat waves, historic droughts, extensive flooding and extraordinary melt activity on Greenland, many are asking if we are seeing long-predicted results of climate change, caused primarily by man-made heat-trapping greenhouse gas emissions. A recent opinion editorial in USA Today argues against linkages between extreme weather and climate change. There are several issues with the USA Today opinion piece that must be addressed.

Sea level rise from global warming magnifies coastal flood risk in Washington, D.C., mid-Atlantic

Sea level rise resulting from global warming will dramatically increase the risk of storm surge flooding in Washington, D.C. and along much of the U.S. coast, according to a new report from Climate Central. The report, “Surging Seas” describes the risk of exceeding established flood levels by 2030, when taking projected sea level rise into account.

What do new findings on ice melt and sea level rise mean?

A new study on melting glaciers and ice caps has received quite a bit of press attention, some of it rather confusing. While the paper (technically a letter) published in the journal Nature, concluded that glaciers and ice caps worldwide lost about 4.3 trillion tons of mass between 2003-2010 - enough to cover the entire United States with water 1.5 feet deep - there were some regions where glaciers and ice caps did not lose nearly as much ice as previously thought.

Top climate change stories of 2011

2011 was an extraordinarily turbulent year for the climate system. The U.S. saw a series of record busting extremes, from a devastating tornado season to an epic drought. The fusillade of extreme events kept global warming in the public conversation even as it slipped to the bottom of the public’s list of concerns in the face of a grim economy. Studies and developments in the emerging area of extreme event attribution top the list of the top climate change stories of 2011.

Top 5 extreme international weather events of 2011

Earlier this week, we looked at the top five extreme weather events to impact the U.S. this year. Not confined to any particular borders, Mother Nature also brought extreme conditions to other parts of the world in 2011, including deadly storms, flooding and prolonged drought. Globally, extreme weather events were responsible for tens of thousands of deaths, not to mention billions of dollars in damages. Let’s take a look at the top 5 extreme weather events to occur outside the U.S. in 2011.

Top 5 extreme weather events of 2011 in the U.S. from tornadoes to wildfires

In a year marked by a relentless assault of extreme weather, several events stand out. Some, like the tornado that leveled Joplin, Missouri on May 22, were extraordinarily devastating and deadly. Others, such as the “Snowtober” storm that buried the Northeast under a crushing load of heavy, wet snow were downright freakish. In a typical weather year, one might expect a few extreme events like these.

Most dire global warming forecasts unlikely, study finds

New research takes some of the most dire global warming projections off the table. A study published last week in the journal Science concludes that the more extreme climate change scenarios, which involve temperature increases of up to 10°F are implausible. Instead, the study finds, we are likely in the midst of a more manageable, but still potentially dangerous, shift in the planet’s climate.

Climategate 2.0: Do new emails undermine global warming science?

Two years ago, much was made about the unauthorized release of thousands of emails featuring private conversations between a group of climate scientists. Dubbed Climategate, these emails showed a few climate scientists being irritable and clubby, and - in the eyes of some - controlling and even deceptive. Some research suggests the ClimateGate episode lowered the public’s trust in climate science and their belief in man-made global warming. In a seeming effort to take another swing at the integrity of climate science, a second crop of emails was anonymously released today, apparently from the same place as 2009: Britain’s University of East Anglia. The “new” emails - while trumpeted by some climate skeptics as “spectacular” and draining life from the manmade global warming movement - mean little substantively from a scientific standpoint, just like the set that preceded them

The report by the United Nations Intergovermental Panel on Climate Change makes clear that warm weather extremes and heavy precipitation events have increased, most likely as a result of manmade climate change. And it projects with a high degree of confidence increasing hot weather and heavy downpours in the future.

2011 on track to be slightly cooler than recent years, but global warming continues

Following 2010, which tied 2005 as the warmest year on record, this year is on track to be considerably cooler, although still unusually warm. Global average surface temperatures for the January through September period were the 11th warmest such period on record, according to new data. The return of La Nina conditions in the tropical Pacific Ocean makes it unlikely that the year will rival last year’s record warmth, although it will continue the streak of consecutive years with warmer than average conditions.

NOAA announced today that August was globally the eighth warmest on record, about one degree above the 20th century average. It also reported the June through August period was 7th warmest on record. June through August temperatures have been warmer than average across the globe for 35 straight years (since 1976). Meanwhile, the National Snow and Ice Data Center (NSIDC) made the preliminary announcement that Arctic ice “appears to have reached its lowest extent for the year.” On September 9, Arctic sea ice extent fell to 4.33 million square kilometers, about 2 million square kilometers below average, second only in minimum extent to 2007 in the satellite record (1979 to present).

Climate scientist cautions against reading too much into this summer’s extreme heat

The heat this summer has been relentless in many parts of the country, particularly in the South Central states, where Oklahoma and Texas had their warmest months on record in July. In fact, as previously noted on this blog, Oklahoma’s statewide average temperature was the warmest monthly statewide average temperature ever recorded in the United States during any month. To learn more about how the extreme heat this summer may shed light on what we can expect as the world warms due to climate change, I turned to Noah Diffenbaugh, a researcher at Stanford’s Woods Institute for the Environment.

The heat event will last all week, with the hottest weather slowly moving eastward into the mid-Atlantic by Wednesday, and sticking around into the weekend.

Intense drought in southern tier in no hurry to loosen grip

There continues to be a dramatic schism dividing Americans. No, I’m not talking about contrasting ideas on what to do about the federal deficit, chronic unemployment, or which candidate to favor in the upcoming 2012 elections, divisive as these matters may be in Washington these days. Instead, I’m referring to the stark contrast between the precipitation “haves” and “have-nots” in this country, which is another divide that is getting wider with time. Several weeks ago, I called attention to the fact that, throughout this spring and early summer, many Americans have concurrently witnessed some of the worst flooding in recent memory and one of the worst droughts in their lifetimes. The stark juxtaposition of floods and drought is remarkable, and it’s showing no signs of abating. In fact, according to federal forecasters, flood risks are likely to remain high during the rest of the summer in parts of the Upper Midwest and West, while the drought hangs tough – or even intensifies its grip on a portion of the South.

New study blames 10-year lull in global warming on China coal use, air pollution

A new study published this week offering a fresh take on what may have driven a temporary, 10-year slowdown in global warming reinforces the scientific hypothesis that human activities are contributing to long-term global warming.

Warm is the new norm

On July 1, NOAA will release its new climate normals, which serve as the basis for comparing current weather to recent history. For the past decade, the climate normals spanned 1971-2000. The new climate normals cover the period 1981-2010. And these new normals are warmer than the normals of the past. Over the United States, the normals have warmed 0.5 degree between the two periods.

NOAA climate report: Array of indicators demonstrate global warming

Earlier today, NOAA released its annual “State of the Climate” report, describing trends in more than 40 climate variables through the year 2010. It clearly and objectively presents indisputable evidence that the Earth’s climate is warming. Or, as put in a briefing to press, the report shows a “consistent and unmistakable signal from the top of the atmosphere to the bottom of the oceans” that the world continues to warm.

Arctic sea ice headed for another major melt

It’s that time of year again, when the air in the Mid-Atlantic feels more like soup, afternoon thunderstorms arrive with regularity, and when news of sweeping changes in a faraway region – the Arctic – tends to pick up. We’re now well into the seasonal Arctic sea ice melt season, and so far, sea ice has been tracking near or below the record low extent reached in 2007, when both the famed Northwest Passage and the Northern Sea Route were open for a time.

After severe spring, a thin line separates wet from dry in the U.S.

When it comes to weather, there’s a general notion that an extreme event in one location will be “balanced out” by an opposite, extreme event in another location. So if there’s a flood in the Mid-Atlantic, then at the same time you might expect a drought to be occurring on the West Coast of the US, or halfway around the world. And this drought might be connected to the flood in some way.

Arizona Wallow fire largest in state history; climate change projections suggest far worse in pipeline

Firefighters in Arizona are reporting the Wallow fire, which has consumed nearly 470,000 acres, is now the most extensive in the state on record, surpassing the Rodeo Chediski fire of 2002. Experts project numerous factors have contributed to the fire’s severity, ranging from forest management practices to this year’s drought. Perhaps more troubling, a report from the National Academy of Sciences published last summer highlights research indicating climate warming as little as one degree celsius may lead to startling increases in wildfire impacts in the West.

Global warming as a heat wave enhancer

Any time it’s hot or hotter than average, the subject of global warming invariably arises. The usual question I hear is: Is this global warming (or climate change)? The answer I give is that global warming is not causing hot weather but almost certainly intensifying it.

Arctic Update: Petermann’s travels

Back in August 2010, CWG helped break the story that a 97-square mile ice island had broken off from the Petermann Glacier in northwest Greenland. Since then, the massive chunk of ice has been on quite a journey: It hit the beach on a small island, broke up into many smaller pieces, and picked up some hitchhikers in the form of iridium beacons used to track the pieces.

Fireflies flashing earlier as climate warms. Are we amidst a ‘renaissance of lightning bugs’?

Summer heat and humidity aren’t the only things to have arrived early in the D.C. area this year. Early last week, Capital Weather Gang commenters reported their first firefly spottings of the season. A warming climate has fireflies along with many other insects appearing earlier in the year than they used to. Recent trends also suggest a ‘renaissance’ of fireflies might be underway, with fireflies increasing not long after scientists feared they might be disappearing.

The atmosphere has been behaving like an unruly teenager, with 275 tornadoes recorded so far this month. What, if anything, might La Nina and global warming have to do with this?

The premise of the Climate Service is that it would make climate information and data available in “accessible and timely” formats to assist people in making decisions. But in their Continuing Resolution for Fiscal Year 2011, Congress and the White House have blocked any funding for the effort.

Putting this winter in context: how severe was it?

For all the talk of this past winter being one for the record books, the reality is much different. While extremely cold conditions gripped some sections of the country at various times during the past few months, the winter of 2010-2011 actually served up temperatures that were just a little cooler than average over the entire contiguous United States. Records from thousands of weather stations across the lower 48 states from December through February show the past season did not even crack the coldest one-third of winters since 1895, when very reliable recordkeeping began. So why was there so much talk about it being so cold?

Congress turns a blind eye to climate science

Last week was a bewildering one for those who recognize the abundance of compelling scientific evidence showing that the climate system is changing, and that this is very likely due in part to human activities. While the news cycle was dominated by the down-to-the-wire budget negotiations in Washington, ongoing unrest in the Middle East, the nuclear crisis in Japan, a major congressional debate on climate change regulations took place in both the House and Senate that vividly demonstrated how far off the rails we’ve gone in public discourse of climate science and policy.

Another record low for Arctic sea ice

Each month seems to bring new evidence of the transformation underway in the rapidly warming Arctic. Late last month, the National Snow and Ice Data Center (NSIDC) announced that the maximum Arctic sea ice extent for 2011, which occurred on March 7, tied for the lowest such value since satellites began making observations in 1979.

The unauthorized release of thousands of emails between several prominent climate researchers in late 2009 - a scandal often referred to as climategate - caused a significant minority of television weathercasters to become increasingly doubtful that manmade climate change is occurring, and that climate scientists and the U.N. Intergovernmental Panel on Climate Change (IPCC) are reliable sources of information, according to a recent study.

Should global warming send us to the bunker?

Last Sunday, the Washington Post ran a provocative essay on the front page of the “Outlook” section by climate activist Mike Tidwell, executive director of the Chesapeake Climate Action Network. In it, Tidwell reveals the lengths to which he is going to prepare himself and his family for what he sees as the now inevitable consequences of climate change. For example, he is stockpiling food, testing guns, and invested in an emergency generator - all in an effort to stave off social unrest that he sees coming down the pike due to climate change-related extreme weather events. The essay is surprising - and completely wrong - in two main respects.

Unfortunately, however, the headline USA Today chose to accompany the story "Scientists: Global warming to blame for big U.S. snowstorms" is scientifically dubious and grossly misleading.

But regardless of which side of the (political) fence you're on, take my little futuristic journey with a grain of salt. The various projections and assumptions are drawn from a variety of sources and are quite controversial, to say the least. Flash forward to December 2076, America's tercentennial (sometimes called tricentennial) year.

With climate change, long-term trends are key

As the start of the New Year rapidly approaches, you're going to hear conflicting news about whether 2010 was the warmest year in the instrumental record. The first salvo has already been fired. On Friday, NASA reported that the "meteorological year" spanning from December 2009 to November 2010 was the warmest in that agency's 131 years of record keeping. Never mind that the meteorological year is relevant only to meteorologists - the news still made headlines.

It's that time of year again - the holiday party season. Time to put on your favorite ugly holiday sweater, and carry on awkward banter with coworkers, friends and relatives. For an ordinary individual who works in a relatively noncontroversial field, holiday parties and other social events can be relatively carefree and fun occasions. But for those who work in a climate science-related discipline, these days such events are more like a series of conversational minefields.

But I doubt Alaskan glaciers come to mind. Consider also the occurrence of glacial related dust storms in Iceland and a possible connection to global warming, and head-scratching might be the principle reaction.

A year after climategate, applying lessons learned

A year ago at this time, while policymakers and journalists (including myself) were gearing up for the Copenhagen Climate Summit, a story began percolating in the blogosphere about a voluminous trove of stolen emails sent between prominent climate scientists. The emails purportedly contained evidence that climate scientists had fudged temperature data and interfered in reviews of studies that did not adhere to mainstream views of manmade climate change. As numerous investigations have found, the scientists involved in the emails did not commit scientific fraud, and the emails' scientific significance was negligible.

Climate expert warns of blogosphere's divisiveness

I recently came across a fascinating interview in Stanford Magazine with a prominent climate scientist there, Stephen Schneider, who has spent decades pondering and trying to improve climate science communication. A professor of interdisciplinary environmental studies who has published widely on climate change, Schneider is the author of the 2009 book "Science as a Contact Sport." Recently, he has spoken out against the "political assaults" and hate speech that have been directed against him and some of his colleagues due to their climate research. In the interview, Schneider makes a thought-provoking case that the blogosphere is fracturing, rather than unifying, the public when it comes to climate science and policy.

Hurricane chimp's cheap shot at climate science

Are poor hurricane season forecasts a reason to doubt climate science? A conservative Washington think tank believes the answer is yes, and they are using a monkey -- pardon me, "Dr. James Hansimian" -- to prove it. (The monkey's name, by the way, is a dig at well known NASA climate scientist James Hansen, who incidentally does not forecast hurricanes).
