Does Climate Change Pose a Risk to Food Supplies?

According to this New York Times article, the UN’s IPCC – the Intergovernmental Panel on Climate Change, the largest group of scientists investigating global climate patterns – “rising temperatures will have some beneficial effects on crops in some places, but that globally they will make it harder for crops to thrive”. The report is just a draft for now (the final report won’t be released until March 2014), but it indicates that the IPCC has new data indicating that crop production will gradually decrease over the next century. That could be particularly troubling, especially considering that Earth’s human population is expected to reach 9 billion people by mid-century.

The Habitable Planet

I just stumbled upon this course at Learner.org, called “The Habitable Planet: A Systems Approach to Environmental Science.” I haven’t had the time yet to fully explore it, but it looks to be a tremendous resource for our class. I recommend you bookmark this page in your browser and come back to it whenever we start a new topic (or when you’re revising for mock exams, topic tests, and/or the IB Exam. I will definitely be consulting it for some activities in future lessons.

Here’s a screenshot of the major topics you’ll find. Screen Shot 2013-10-02 at 09.29.23
