Wunderground launches new Local Climate Change section

In honor of Earth Day on Sunday, wunderground has launched a new Climate Change Center, which gives people resources to understand how the climate is changing both globally and in their local neighborhoods. I am particularly pleased with our Local Climate Change feature, which allows one to see how temperature and precipitation have changed over the past 100+ years at the nearest station with a long period of measurements. Predictions from climate models on what the next 100 years may bring are overlaid for each station. Data for most U.S. stations goes back to 1895; we have data for a few stations in Europe that extend back to the 1700s. Berlin has the longest period of record in this database, with data back to 1702.


Figure 1. Screenshot of the Local Climate Change page for Washington, DC. Measured temperatures since 1820 are shown in grey. By clicking on the "Show post-1900 trend:" box, we see that the trend since 1900 has been for an increase in temperature of 1.5°C (2.7°F) per century. Moving the thin vertical red line over the image using the mouse shows that the warmest year on record in Washington D.C. was 1991. Predictions for a future with low emissions of heat-trapping gases like carbon dioxide are shown in yellow; the high emissions prediction is shown in red. Separate tabs are available to examine precipitation and snow.

Skeptical?
Also included in the new Climate Change Center is a section addressing the common skeptical arguments made against climate change. We offer three levels of explanation. The "Basic" level is the default, but one can also see more technical in-depth discussions by clicking on the "See All Explanation Levels" link. The material was developed by physicist John Cook for his excellent skepticalscience.com web site, which is widely referenced in the climate science communication community.


Video 1. I'm featured in this video on extreme weather and climate change done by veteran videographer Peter Sinclair for the Yale forum on Climate Change and the Media this month. I'm also featured in Part 1 of this series. Our new Climate Change Center has a section for climate change videos, which includes a twice-monthly feature from GreenTV detailing the world's notable wild weather events of the past two weeks.

Earth: the Operator's Manual airs Sunday night
Penn State climate scientist Dr. Richard Alley hosts parts II and III of Earth: the Operator's Manual on PBS beginning at 7pm Sunday, April 22--Earth Day. Part I of this excellent series aired in April 2011. The series gives an overview of climate change, but primarily focuses on what we can do to help slow down climate change though smart energy choices. Dr. Alley, a registered Republican, geologist, and former oil company employee, is the Evan Pugh Professor of Geosciences at the Pennsylvania State University, and one of the most respected and widely published world experts on climate change. Dr. Alley has testified before Congress on climate change issues, served as lead author of "Chapter 4: Observations: Changes in Snow, Ice and Frozen Ground" for the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), and is author of more than 170 peer-reviewed scientific articles on Earth's climate. He is also the author of a book I highly recommend--The Two Mile Time Machine, a superb account of Earth's climate history as deduced from the 2-mile long Greenland ice cores. Dr. Alley is an excellent and engaging speaker, and I highly recommend listening to his 45-minute keynote speech, "The Biggest Control Knob: CO2 in Earth's Climate History", given at the 2010 American Geophysical Union meeting, via this very watchable recording showing his slides as he speaks in one corner of the video. If you want to understand why scientists are so certain of the link between CO2 and Earth's climate, this is a must-see lecture.

Have a great weekend, everyone, and I'll be back Monday with a new post. I'd like to thank Wunderground meteorologist, Angela Fritz for spearheading the creating the new Climate Change Center; it's a product I'll be referring to frequently in the future, and one we'll be updating in the coming months with data on local sea level rise, fire risk, and drought.

That was the "early" 1800's and it was cold. Almost ran out of oil lamps.

Well... just heard on the radio that there was some damage caused by our overnight storm on the eastern end of the island [New Providence]. People are claiming it was a tornado, but I wouldn't be surprised if it was a downburst instead. Regardless, some people apparently lost their roofs.

Here we had extensive leaf and twig damage, and 1/2 dozen young mangos were downed.

More on this as I get information.

Not only is today the one year anniversary of the St. Louis EF4 tornado, Earth Day, and the beginning of several major tornado outbreaks over the past few years, it is also the first day of the first ever National Severe Weather Preparedness Week that runs from April 22 to April 28.

Wow.

I can't believe I forgot about the Joplin tornado.

I retract my previous statement.

lol.

Well Joplin is near the Kansas-Oklahoma-Missouri border so that's one thing. But Missouri always gets alot of tornadoes.

Henry Margusity Fan Club:


I saw the Euro last weekend, we all did, but instead rushing out and hyping that a historical snowstorm is coming, I/we took the cautious route knowing that storms like sometimes do not occur. So I give JB kudos for reading the Euro correctly. I will be the first to say that I did not believe the storm was coming and under-predicted the snow event until I was sure. Yes I would agree, I did not hype this one up, but in the end, I did change course and go with the consensus of the models Friday and Saturday. So I will be the first to say that I was wrong not going with the Euro idea initially. Part of me does not want to see snow in April, especially knowing the damage that can be done.

As for JB, my rants are entirely due to the fact that he is saying things about good people and good organizations which are totally wrong to be saying. If he has a point about global cooling, then make it but don't call people liars because they express their views on global warming. Dr Mann for example is a good person and a good family man and he does not need anyone to be calling him a liar. He's earned his place in science at Penn State by doing the research and work to come up with his conclusions on global warming. If you don't like his conclusions, so be it, but don't call him a liar and don't call my meteorological organization the AMS liars because you don't agree with them. Polluting our Earth is a serious matter and whether global cooling or warming is occurring does not matter to me, what matters is the end result and that result could be something catastrophic if don't stop polluting our Earth. So instead of bashing people and calling them liars, propose changes to help the environment.


Even if he is incorrect, Henry Margusity is a great guy. I met him in person and it was an honor. He is and will be my favorite met!


I always considered Henry M. a bit of a goofball with his propensity to overhype everything and invent pseudoscientific theories like the Japanese tsunami debris caused the March heatwave, but that was actually a nice comment. Bastardi has taken to attacking everybody he disagrees with through social media.
