I Am Cheating

nasa-sep-2016I thought maybe I was done with my blog posts. You may have thought the same. But, this climate change stuff really concerns me and I am not sure we are all paying attention.

I say I am ‘cheating’ because my message today is not my own. I am sending you to today’s Climate Cast blog post – a blog I follow here in MN. I would encourage you to read the complete post no matter where you are on the planet.

Here is the beginning of the post:

You could call it, “weather gone weird.” Climate out of control might be a more appropriate name.

A rare October severe weather risk in Minnesota. 100 degrees in Kansas on October 17th? The hottest September on record globally. A NASA scientist says 2016 is now “locked in” as earth’s next new ‘warmest year on record’ globally.

The thread that ties it all together? All are symptoms of a dramatically warmer planet earth. . . . keep reading

How does this affect animal agriculture? I am more inclined to think about how these kinds of changes to our climate WON’T affect animal agriculture.

. . . . . I can’t  think of anything.

My meager advice? Know your climate and how it is changing. Evaluate your vulnerabilities. Plan for it. All of this is summed up in the Adaptation Planning Guide developed by this project.

Always Considering Climate — David

And I am thinking about having a hamburger for supper too.

When news about the WHO report linking  processed meat, red meat and colorectal cancer came out this week I found myself doubting all scientists . . . and anyone associated with the  government. What next? Will they will tell me not to eat eggs?

As I said in last week’s post, science in biological systems is REALLY hard. Those questioning the WHO report  Continue reading

Blue Lines and Basketballs

I have another guest blog this week. This time it is from Pam Knox, the climatologist on our project team. She posted this blog yesterday and I thought it was interesting enough to share with all of you.

I especially liked the image of the atmospheric layer being as thin around the earth as the thickness of a balloon latex is around a basketball. I had to do the math and yes indeed, if you do the ratio of diameter of earth to the thickness of the atmosphere (out to the stratosphere where 99% of our atmosphere exists (about 50 km or 30 miles) ) you get a comparative layer over the basketball of about 0.1 mm  . . . the thickness of a balloon or piece of paper. That graphical presentation of the earth surrounded in a pillow of atmosphere (see image above) that extends out further than the diameter of the earth is misleading!! The atmosphere thickness on an earth image this size would be thinner than a pencil line. Crazy! Continue reading

AACC Takes Center Stage at 2015 Waste to Worth

w2w
Waste to Worth 2015 Westin Hotel Seattle WA. March 30 to April 3.

This project (AACC) is all about education and building expertise on the topic of animal agriculture and climate change. The issue is not going away anytime soon and the more people we have that understand the issues the better off we all will be. As such, this post is a blatant advertisement for an upcoming educational event in Seattle the end of this month submitted by David Smith, Texas A&M. David is a regional coordinator for this project and also one of the main conference planners for Waste to Worth 2015. Here is what he has to say. Continue reading
