I received a letter recently from Susan Hall, the Media Specialist at the National Inventors Hall of Fame STEM (Science Technology Engineering & Mathematics) School in Ohio. Ms. Hall wrote:


 

 

 

As a 5-8th grade school, we are using your book GLOBAL WARMING in a summer Cyber e-reading program, paired with a fiction book titled FIRST LIGHT by Rebecca Stead, which also deals with global warming. Our very curious learners are enthusiastic about your book and have some questions for you!

 

 

 


What a good idea to study this topic through both fictional and nonfiction texts! So, I’ve agreed to answer four questions from Ms. Hall’s summer students here on my blog. I hope that other readers will find this interesting, as well.

Why do so many people think global warming is a government conspiracy? (Andrew)

It is difficult to answer this question because no one really knows why people’s opinions are so diverse. The only thing that I can really answer is why I think that global warming is REAL and NOT a conspiracy. I think global warming is really happening because the overwhelming evidence of countless studies is that global warming does exist and that it is influenced by human activities. Just because a certain percentage of people believe that there is a government conspiracy is not evidence that there is one. For example, some people believe that humans and dinosaurs lived on Earth at the same time despite the fact that all the evidence points to the fact that dinosaurs became extinct tens of millions of years before humans appeared. 

How could we simulate the earth’s atmosphere to study and test the effects of global warming? (Daniel)

Setting up a computer simulation to track complex climate changes is very difficult. Yet the ones that have been done all seem to suggest that global warming is real and happening very quickly. 

What change in energy use would most dramatically slow down global warming? (Camryn)

Becoming more energy efficient is the single most important change we can help to bring about. The largest single source of greenhouse gases is electric power generation. The average home contributes more to global warming that an average car. That’s because much of the energy comes from power plants that burn fossil fuel to make electricity. So the less electricity we use, the more we are helping cut down on the use of fossil fuels. 

Is it possible to reverse global warming? (Miriam)

Many scientists think that it’s possible to slow it down rather than just reversing the process. Either way, it’s to all our advantage if we conserve energy to reduce our use of fossil fuels.
