Warren Allmon, Director of the Paleontological Research Institution and its Museum of the Earth appeared on the PRI (Public Radio International) show The Takeaway this morning. He spoke about the potential evolutionary consequences of climate change.

A bit of good news
When reading the news, whether it be social or scientific, I am always bothered by how many articles are full of doom and gloom. So when I come across one that actually points out things that have gone right, I feel the urge to share it with you.
Check out this article
This article talks about our effect on acid rain. In particular, I like how it embraces the idea of how scientific research on a problem, understanding its social implications, and creating effective legislation actually can mitigate some of our environmental damage.
I'm glad to see that the US has effectively dealt with the largest causes of acid rain, and that we're still ahead of the curve compared with other countries on at least one ecological issue.
Happy Friday!

The Stimulus Goes Green...
I just came across a short list of tax credits, rebates and write-offs in the new stimulus plan...Some of the items are pretty great! Check them out below:
Looking to finally purchase that hybrid? Do it NOW -- you can get up to a $7,500.00 tax credit!
Solar Panels? Go for it...You're entitled to a 30% tax rebate for your purchase!
Live in Ithaca? Take TCAT and you will be able to write-off up to $230.00 a month for the next two years on your taxes!!!!!!!
Want a home wind turbine? Do it NOW -- you can get a tax credit for 30% of the total cost of the turbine!
Looking to replace your windows or front door? Do it this year and get a tax write-off of up to $1,500.00 by purchasing new windows or exterior dorrs with a U-factor of .3 or less!

I know it can sometimes seem that "going green" is expensive, perhaps these credits, rebates, and write-offs will offset that!

Findings of an interesting NSF sponsored project
Check out this article about future climate change's impact on global agriculture.
From my perspective, it really is a scary situation, with the predictions of the Earth's population increase and our current prospects for using biofuels to power our cars. We'll have twice as many people, 1/2 the space suitable for growing crops, and many of those crops earmarked for transportation and NOT food product.
Let us know your thoughts!

Dan Miller's A Really Inconvenient Truth
Yesterday I attended a talk at Cornell by Dan Miller titled "A Really Inconvenient Truth." He was one of the people trained by Al Gore to give the "Inconvenient Truth" lecture to businesses, schools, etc. He also gives another, slightly darker, talk. That's the one I mentioned above. You can read the outline of the talk here.
According to Miller...
The IPCC (Intergovernmental Panel on Climate Change) produces a consensus report of climate and other scientists actively working on climate change that summarizes the known research and the certainty levels of the scientists on various effects. Policy-makers use this document to better understand the science and what policies should be enacted to prevent or mitigate for future damage.
The IPCC report shows what could happen in the future based on their linear models of climate change and predictions based on societal behavior (i.e. we stop emissions immediately, we don't do anything, we emit less, etc). Bad things for the climate are predicted if we don't change our behavior soon based on IPCC models of the climate.
However, IPCC is a consensus opinion, meaning that they have to use the best understood models and find an agreement between many different scientists. Therefore, the consensus opinion is more conservative than many IPCC scientists would prefer. It also uses linear models, which are easier to calculate, but don't always reflect the way the natural world works. Things like feedback cycles are not incorporated into the IPCC's predictions.
Feedback cycles to worry about that weren't addressed by IPCC models:
1) Permafrost
2) Glacial melt feedback loops
3) Methane traps
Permafrost - In Siberia, Canada, and Alaska, portions of the ground are permanently frozen year-round. The ground in many of these places is made of peat, which has a high organic content. The peat was never allowed to decompose because it was frozen, thereby trapping carbon dioxide in the frozen ground.
As it gets warmer, the ground melts and the peat begins to decompose. This process releases carbon dioxide into the atmosphere, which raises the temperature a little. This causes more permafrost to melt, which releases more carbon dioxide, which raises the temperature a little more...this is a positive feedback cycle.
Glacial melt - Arctic sea ice is ice that floats on the water near the poles. It is connected to land in some way, and prevents the glaciers from traveling into the water. As the sea ice melts, the glaciers are not held back from the oceans. This will expose the glaciers to warmer temperatures and cause the ice to melt. This will cause sea level to rise and will encourage more glacial movement.
Methane Traps - This one isn't likely to occur in the near future, but may happen someday. Methane is stored frozen at the bottom of the ocean, and the gas is 20x as effective as an atmospheric blanket as carbon dioxide. The ocean warms first at the surface, and eventually (over, say 1000 years) the heat could cycle through to the bottom. If parts of the ocean warm enough to release methane gas, this will raise the temperature of the Earth. When that happens, the oceans will warm more, more methane gas will be released, and the temperature of Earth will rise further...

FORD - Found On Road....recycleD?
So, a friend of mine was reading his copy of "My Ford," Fall 2008 issue, and he pointed out an article in the magazine that talked about the ability for vehicles to be recycled. Unsuccessfully having tried to find a copy of the magazine issue online to post for you all, I'll recap the highlights of the story.
Written by Claudia Duranceau, Senior Research Recycling Engineer at Ford, the article points out that 52% of paper and 45% of aluminum cans are recycled. Fairly decent, right? Though I agree we could do better. However, she sais that more than 95% of cars, trucks, vans, etc., are recycled at the end of their lives. Personally I found this amazing. We have incentives for paper and can recycling in place, and still our vehicles are much more likely to be recycled.
Value of the product is no doubt the culprit. Duranceau sais that 84% of a car's material, by weight, can be recycled, and that FORD is designing the newer vehicles to be easier to take apart, increasing the chances of recycling individual parts. FORD is also a part of the Vehicle Recycling Partnership, who's goal is to increase vehicle recycling in an environmentally friendly way.
Finally, the article showed a Ford Taurus, and what it was composed of. 65% steel, 20% plastics, 5% aluminum, 5% other metals, and 5% gas, fluid, etc. Though they didn't break down which of these were recyclable, one can assume most of the metals, and some of the plastics, could be recycled.
Certainly an interesting read!

Yellowstone Park feels the effect of climate change
Yellowstone National Park is one of the oldest National Parks in the United States. It is around 3,500 square miles of protected lands, beautiful scenery, and thriving ecosystems. Research suggests, however, that it is already feeling the effects of climate change.
Read Article Here
An interesting perspective...what are the effects of ecosystems with salamanders, frogs, and other sensitive organisms like in areas not protected by the park service? What don't we know about the critters in our backyard?
It's amazing how these small organisms, along with other critters like bugs, larvae, and plants, are capable of measuring the health of an entire watershed or region.
