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.

Tazmaniac has predicted an early start for EPAC and is calling for 32 storms. What do you think?

32 might be pushing it... I think more like 20-23 storms, maybe 7-9 majors

Its been a few years since the last one hit but they always remind me of the one that happened close to the same area in 1976 killing 20000 people in guatemala.

Back again. I went out for something, and while gone decided to detour through the area allegedly hit by a tornado. I observed one house with about 1/2 of its roof being replaced, another where an add-on porch seemed to have been wind-shredded, and evidence of high winds in the form of uprooted trees, downed limbs and in the case of larger trees, leaves completely missing. One tree looked like post-cat 2 damage. I didn't get any photos, though.

I dunno how expert our mets are at judging tornado damage; it's not really an area of expertise they woul have concentrated on in their training. I certainly don't have any extensive experience myself. But aside from the roof damage, most of what I saw could have been done by straight line winds over a period of time and given moist soil.

The roof damage looked like tornado, not hurricane. The western side of the roof was perfectly fine; the eastern side was gone.


Dayum, Nassau had a tornado yesterday? I was in Miami xD

Well You've got:-
Storms, blizzards, heat waves and even had a 91L off your coast!
All we have got is a boring French National election and the standard cold blustery low over the UK.

Just like most hollywood movies....2012 had a lot of fake stuff and some people that watched the movie where asking if what occured in the movie will happen in reality
I don't think that really is going to happen.Unless something really weird goes on in the earths center.

Well the tsunami could technically happen. You would need a land mass displacement equal to that of the entire nation of India falling into the ocean at once. Or you can always go with a massive meteor/comet impacting the ocean. Everything they showed is possible but not with the correct forces being applied to cause the events. The only thing that was not possible in the movie was the ash flow making it all the way to LA and the magnitude 10 earthquake.

Yeah, but close to the end they were saying that only some new mountains in Africa were not covered by water....this is also very unlikely or not possible
