“How to Save the Polar Bears” Global Warming Panel from SkepchickCon 2012

Posted by mattusmaximus on July 17, 2012

Now that I’m back from TAM 2012, I am finally catching up on some blogging.  In this post, I wanted to share a rough transcript I made of another panel I saw the weekend before TAM at Convergence/SkepchickCon 2012 titled “How to Save the Polar Bears” – as the name implies, the subject was on how to address questions of the effects of global warming as well as climate change denialism.  Read on…

How to Save the Polar Bears

with Greg Laden, Shawn Otto, Maggie Koerth-Baker, John Abraham, and Desiree Schell (moderator)


Desiree: Let’s all commit now that climate change is indeed a real thing that is occurring. Greg, can you start with telling us the effects of climate change?

Greg: I’ll first talk about the effects of all the CO2 being released. The first effect is that it is warmer. For example, we are now experiencing the warmest year on record (so far). There are also likely to be drastic shifts in the weather patterns due to the amount of heat the atmosphere can hold. It probably means in more areas more rain in short bursts – so more droughts interrupted by heavy rains.

Also, the oceans will become more acidic, so organisms which are affected by high acid water will be hurt.

Finally, see level rise… glaciers melt, water expands, so the ocean level goes up. It could be a big factor in the short term.

Desiree: there are other more tangible effects like on agriculture.

Greg: yes, for example, many trees are getting killed by parasites because those parasites valve moved into regions (due to climate change) they never were before. Also, plants are drying out due to drought and this is leading to a lot of nasty wildfires.

People think that climate change effects is a future thing, but since the 1970s we have seen agricultural failures and desertification which are likely already linked to climate change. It is currently occurring.

Desiree: one thing that might change is disease patterns.

Greg: yes, many disease patterns have changed. Most epidemic diseases we as humans experience are due to things we have changed about our environment.

We have become a bit complacent about diseases, because in the 1930s we developed antibiotics. The problem is with the changes we are making now due to climate change, these disease effects are not so easily fought.

Desiree: Maggie, can you speak to power usage?

Maggie: the biggest energy usage we have now is buildings, more than transportation, and we use most of that energy to perfect our indoor climate (AC) which affects the outdoor climate, and so on. This also affects our power grids, because there is an increase in demand for electricity due to the higher temperatures. And the grid is much more sensitive than people think, and in these extremes you can get blackouts.

Desiree: Shawn, what was the political response to these issues?

Shawn: Nothing. An attempt was made in 2010 to address these issues, but about 500 million dollars was poured into Congress by the energy lobbyists to defeat any kind of climate bill. And the Obama administration had to make a calculated decision to go with healthcare reform instead.

There have been many on the right who have attempted to downplay climate change mitigation. Many people are pushing a “teach the controversy” argument against the teaching of climate change science. They wish to replace political opinion with actual science. There have been political attempts to make sea level rise “illegal” – North Carolina almost passed a bill making it illegal for communities to consider the effect of sea level rise unless the legislation gives prior permission, and if they do the community cannot go with the science
(about 1 meter in a century) but instead about 8 inches.

Virginia recently followed suit, saying we cannot talk about “sea level rise” but “frequent flooding” instead. This kind of throwing up political smokescreens is what is going on now.

In a way, you cannot blame the (public) corporations for this so much because they are required by law to pursue profits for shareholders on quarterly basis. So money drives a lot of it.
