| Posted: 09 Nov 2017 04:00 AM PST Hi! We are Seth Wynes and Kimberly Nicholas, authors of a recent scientific study that found the four most important choices individuals in industrialized countries can make for the climate are not being talked about by governments and science textbooks. We are joined by Kate Baggaley, a science journalist who wrote about in this story Individual decisions have a huge influence on the amount of greenhouse gas released into the atmosphere, and thus the pace of climate change. Our research of global sustainability in Canada and Sweden, compares how effective 31 lifestyle choices are at reducing emission of carbon dioxide, methane, and other greenhouse gases. The decisions include everything from recycling and dry-hanging clothes, to changing to a plant-based diet and having one fewer child. The findings show that many of the most commonly adopted strategies are far less effective than the ones we don't ordinarily hear about. Namely, having one fewer child, which would result in an average of 58.6 metric tons of CO2-equivalent (tCO2e) emission reductions for developed countries per year. The next most effective items on the list are living car-free (2.4 tCO2e per year), avoiding air travel (1.6 tCO2e per year) and eating a plant-based diet (0.8 tCO2e per year). Commonly mentioned actions like recycling are much less effective (0.2 tCO2e per year). Given these findings, we say that education should focus on high-impact changes that have a greater potential to reduce emissions, rather than low-impact actions that are the current focus of high school science textbooks and government recommendations. The research is meant to guide those who want to curb their contribution to the amount of greenhouse gas in the atmosphere, rather than to instruct individuals on the personal decisions they make. Here are the published findings: http://iopscience.iop.org/article/10.1088/1748-9326/aa7541/meta And here is a write-up on the research, including comments from researcher Seth Wynes: NBC News MACH Guests: Seth Wynes, Graduate Student of Geography at the University of British Columbia in Vancouver, currently pursuing a Doctor of Philosophy Degree. He can take questions on the study motivation, design and findings as well as climate change education. Kim Nicholas, Associate Professor of Sustainability Science at the Lund University Centre for Sustainability Studies (LUCSUS) in Lund, Sweden. She can take questions on the study's sustainability and social or ethical implications. Kate Baggaley, Master's Degree in Science, Health, and Environmental Reporting from New York University and a Bachelor's Degree in Biology from Vassar College. She can take questions on media and public response to climate and environmental research. We'll be answering questions starting at 11 AM ET (16 UT). Ask us anything! -- Edit -- Thank you all for the questions! [link] [comments]  |

| When radio waves pass through objects, are they refracted like light through a glass of water? Posted: 12 Nov 2017 09:19 PM PST |
| How close are we to utilizing graphene in everyday life? Posted: 12 Nov 2017 11:42 AM PST |
| What are the velocities of the arms of the milky way? Posted: 13 Nov 2017 05:09 AM PST I'm on a radio astronomy research team with my college, and I'm in charge of finding the velocities of the arms of the galaxy so that when we take data from telescopes we can analyze it (we're using a 40-foot national telescope). Can someone please explain how to do this? I'm having trouble knowing where to start, and my team leader is getting impatient. [link] [comments]  |

| Posted: 12 Nov 2017 11:02 PM PST I was looking at this map of seismic risk.
Why is this? [link] [comments]  |
| Posted: 12 Nov 2017 12:16 PM PST Not sure if this would go under social science or earth science. I've seen lots of companies and organizations in recent years push for "paperless" systems where everything is done electronically. Has this movement made an impact on paper consumption and pollution worldwide in a noticeable way so far? [link] [comments]  |
| Posted: 12 Nov 2017 04:11 PM PST I have read that the the stars moving on the outside of galaxies would fly out of orbit at their speeds. Why is gravity not considered strong enough to keep them in orbit? [link] [comments]  |
| How does the USB port know what I connected to it? Posted: 12 Nov 2017 11:06 PM PST From what I understand/infer, the moment I plug in a device it starts by telling the computer what it is. The computer looks for a driver and then interprets the signals according to the driver. But, I don't really get what per say is being sent i.e is it a mac-address? some strings that it looks up? There has to be some standard coding that helps it narrow the search as to what the devices are correct?(if there is i would love if you could provide references) Also, say if I wanted to just write a program that told me what is currently plugged into my computer how would I go about doing it?

| How far do you have to go to escape the gravity of our solar system? Posted: 12 Nov 2017 04:09 PM PST From my understanding, gravity is stronger the closer you are to a high mass object. Is there a distance when this force disappears? Is it possible that there is always some sort of gravitational force at work? [link] [comments]  |
| Posted: 12 Nov 2017 09:01 AM PST By non-recyclable material, I mean the "wrong" type of material such as a banana peel in a batch of plastic recycling, some cardboard in metal recycling, etc. [link] [comments]  |
| Posted: 12 Nov 2017 07:47 PM PST To clarify, do fat, sugars, calories, etc. interact with the human body in such a way that junk food weighing three ounces could make your body gain more than three ounces? Is this physically possible through the body's internal chemistry somehow? And, if so, how does this process work? [link] [comments]  |

| What happens to all of the kinetic energy from matter falling into a black hole? Posted: 12 Nov 2017 06:18 PM PST Assuming I understand them correctly, matter falls into the singularity at the local relative speed of light. What happens to all that kinetic energy when it reaches the center? Sorry if this is an uninformed question. [link] [comments]  |
| What exactly goes on when a protostar turns into a star? Posted: 12 Nov 2017 03:34 PM PST I get that fusion happens but the usual explanations just gloss over this. Do they expand, contract? What happens to the accretion disk? Nothing is ever explained besides "fusion happen". [link] [comments]  |

| Why does your throat hurt when you are sick? Posted: 12 Nov 2017 05:50 PM PST |
| Does the structure/properties of ice water change as the ice drops further below freezing? Posted: 13 Nov 2017 01:02 AM PST |
