Infographic: I’m glad we don’t have as much impact on the atmosphere as bacteria

As humans, we are contributing to global warming every time we breathe. Luckily, this contribution doesn’t amount to a hill of beans. The amount of carbon dioxide we excrete while breathing is easily converted to other molecules by other organisms on Earth. We, as humans, number roughly 7 billion. That is a lot of carbon dioxide. However, we are outnumbered by plants and trees by several orders of magnitude that consume this carbon dioxide and convert it back to the oxygen we so desperately need and make carbohydrates in the process.

Now, think about this: 7 billion humans converted to microbes living in the soil would amount to a pinch of soil. As you should know, there is much more than a pinch of soil on the planet, and that does not take into account the waters of Earth. So, doesn’t it make sense that what these microbes take in and “breathe” out has a much much greater impact on the composition of our atmosphere? Luckily, microbes, in the general sense, don’t breathe carbon dioxide under most conditions and some microbes like algae consume carbon dioxide like plants and give us oxygen in return.

Affect of each domain of life on the composition of the atmosphere.

The figure above shows how simplistic plants and animals are compared to prokaryotes in regards to what we all “breathe”. This is not an exhaustive list of molecules microbes use; it’s just one small group of bacteria from the genus Geobacter. This complexity helps put things in perspective.

Put #government labs to work on #climatechange – The Washington Post

I want to start by saying I am part of the national labs system. I’m at Oak Ridge National Laboratory and work as a science writer for a small group that publishes for the Office of Biological and Environmental Research within DOE. That being said, I’m still a concerned citizen as well. I want my daughter to experience this planet as I have. This opinion article in the Washington Post by Naomi Oreskes, a professor of history and science studies at the University of California at San Diego, is brilliant and articulate. Straight at the heart of what the Executive Branch can do without going through the cluster f#ck that is Congress. However, as always, it comes down to money and reapportioning funding for the suggested changes in this article would essentially have to go through Congress. Here are the suggestions in the article:

●Alternative energy. The climate problem is fundamentally an energy problem. While strides have been made — by both industry and government — in developing alternative energy sources, renewables still provide only a sliver of the U.S. energy profile. The scale of renewable energy research and development needs to be radically increased.

●Carbon capture and storage. Shale gas development in the United States and Canada is generating jobs and revenue and could substantially decrease our reliance on petroleum. But shale gas is still gas — methane: a fossil fuel that when burned produces carbon dioxide. Large-scale development may exacerbate the climate problem if inexpensive gas undercuts the market for renewables. If, however, shale gas development could be coupled with carbon capture and storage, trapping the carbon dioxide produced, then this resource might be usable without worsening climate change.

●Energy storage. Wind and solar are real sources of energy, but only when the wind blows or the sun shines. Yet many wind and solar projects produce excess capacity that could be used later or elsewhere if it could be stored. Ideas for renewable-energy storage need to be developed and expanded.

●Social obstacles to energy efficiency. Numerous studies show that Americans could cut energy use by 30 percent or more through efficiency measures and save money at the same time. Yet most of us don’t. This is a bit of a mystery for economists; social science research in the laboratory system should be mobilized to figure out why we don’t save energy and money even when we could.

●Climate engineering. Deliberate alteration of the climate to compensate for inadvertent modification is a technically and ethically troubling concept, but it may be one of the only available means to slow climate warming and buy time while other solutions are implemented. Physical scientists should expand their work in this area, and social scientists and humanists should be enlisted to address the ethical dimensions and governance issues.

Curiosity-driven science has not yet provided the solutions to global warming, and universities are not well situated to address a single, overarching problem. Moreover, the president does not have authority over our nation’s universities. But he does have authority over our national laboratory system. The labs have been mobilized before; the time has come to mobilize them again.

 

The last part (in bold) is a great remark and one I completely agree with. These suggestions should be sent to the White House, perhaps through the petitions website. Are you with me?

Climate Change Series: Where Science And Ethics Meet | Cognoscenti.

 

This is a great, well thought out take on what is happening and what needs to happen. I like the emphasis on the ethical issues involved with changes in climate. I can’t wait to read the rest of the series.

Using heat from the Earth’s core for energy production

I was looking over the Office of Science (DOE) webpage and found Dr. Brinkman’s presentations page.

I hadn’t noticed this one before; harnessing geothermal source for a novel mass production power plant. The first activity of the Enhanced Geothermal Systems (EGS) are planned for next year.
