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.

You would laugh a million times harder if you looked at some of the comments made shortly after Don became a TS... People were calling for it to become a major hurricane, no joke!

Neat, lol.

Quoting TropicalAnalystwx13 (August 22, 2011):
This is what I see right now...There is a weakness located just to the north of Irene. That being said, a brief more northerly motion should occur soon. However, it shouldn't last long as the Bermuda high begins to move back in. Then, a second trough should come in. This will, just as the first one, turn Irene north some, but the Bermuda high will build back in and force the system was westward. Lastly, another trough should move in, which should be the strongest, and this should take Irene NNW/N into northeastern South Carolina or southeastern North Carolina.

At this time, I am predicted a low-mid level Category 3 hurricane, but if Irene undergoes rapid intensification, a Category 4 cannot be ruled out.

You are correct and I totally understand your point on the surge. Last west coast hurricane surge event was Donna correct?


There was surge with Donna, but because of the way it came in it was a lot less than if it had approached at the same speed from the NW Caribbean or Bay of Campeche.

Hi all, guess I was too worried about the start of my trip to Oklahoma this past week ...had no problems in getting there on Sunday but it was challange to get back. My flight from Dallas to Houston was canceled on Friday ...and I was on three standby flights and didnt get on any of them ...wound up making it back to Houston about 10:00 this morning ...bad night but happy to be home.

Sadly I leave again tomorrow to go back to Tulsa this time ..please, no more storms

Tulsa, OK is in the clear through at least the middle, if not the end, of the week.

It's all good. I was just saying no one on the West Coast has experienced a MAJOR surge event, so when one happens there are more than likely going to be a lot of people unprepared for it.

Hurricane Wilma's landfall in Leftyy's blog!


543. seflagamma 6:54 AM AST on October 24, 2005

Just got up again after going back to bed around 4am.
It is almost 7am now and the winds are howling and roaring. Raining. Winds from EAst now and wipping my trees. In gusts they lay flat. It is bad now and the worse is yet to come. One wall of screen in my patio (east side) has blown in. I see it is just now making landfall around Marco (if what is see is correct). Did not have time to read


that was my last post from my home computer for a week! LOL

What a dud of a big rain even for S.W. Florida. Local Met was saying 3" - 5" of rain today for our area and I've only seen .33" (and that was last night). I've had no measureable precipitation today.

We really need the rain, so this was a major disappointment. And Sunday afternoon through Tuesday will be breezy and very dry just adding to the fire danger.
I hope this event was enough to put out the fires that was blowing smoke this way.
