| Posted: 26 Feb 2020 04:00 AM PST We were two of the lead negotiators of the Paris Climate Agreement, and continue to dedicate our careers and lives to stopping the climate crisis -- Christiana was Executive Secretary of the United Nations Framework Convention on Climate Change (UNFCCC) 2010-2016 and Tom was a senior member of the UN team that created the Paris Agreement on Climate Change, signed by 195 countries in 2015. AUA! ** We are at a critical decision making moment that will determine the entire future of humanity.** This year and the next ten are going to have more of an impact on the future of the Earth than any other decade in history. We are facing either a world of breakdown and conflict, of floods and disasters that will be close to home more quickly than we could have imagined, where hope has slipped away - OR - a world that is renewed, where forests have regrown and cities are remade, where your children are not afraid to have children of their own. That reality is overwhelming for most of us because we don't know what to do about it. While we do not deny that daunting challenges are ahead, we do not agree with the idea that we are somehow already doomed to a devastating future or that humanity is somehow flawed and incapable of responding to big problems; we are fully convinced that we can avert the worst of the climate crisis through a change of mindset and the ten actions outlined in our book. We are really excited to be here today to answer all of your questions around climate change and creating together the world that we all hope to see -- and live in! We will be here at 4:30pm ET today, so ask us anything and let's talk about how to wade through all of the existing news and information about climate issues, and really distill it all down so we can each create our own action plans to collectively survive the climate crisis. You can see more on our book at https://globaloptimism.com and also connect with us further on Twitter at @cfigueres and @tomcarnac. We also host a podcast called Outrage & Optimism where we interview journalists and global leaders on how to drive social and environmental change. Again, our guests will be here at 4:30pm ET (21:30 UT). [link] [comments]  |

| Ask Anything Wednesday - Economics, Political Science, Linguistics, Anthropology Posted: 26 Feb 2020 07:09 AM PST Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Economics, Political Science, Linguistics, Anthropology Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...". Asking Questions: Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists. Answering Questions: Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience. If you would like to become a member of the AskScience panel, please refer to the information provided here. Past AskAnythingWednesday posts can be found here. Ask away! [link] [comments]  |

| Posted: 25 Feb 2020 03:22 PM PST Im in process of painting Binary black holes and Im using some images as reference. I was wanderimg why are black holes often displayed with acreation disk which has darker colors (orange to almost red) on the outer rim and lighter colors(yellow to almost white) on the inner ring, closer to core (or horizon). Is there science behind this "popular" picture of black holes? And any science or knowledge behind "Binary black holes" you could share? Thank you for any answer. [link] [comments]  |
| Why are most of the oldest living people in the world female? Posted: 25 Feb 2020 04:24 PM PST According to this list most of the oldest living people in the world are female. Why is that the case? [link] [comments]  |
| Why do cell membranes not aggregate? Posted: 25 Feb 2020 09:20 AM PST I was wondering why cell membranes don't tend to aggregate together? Lipids in suspension tend to aggregate over time, especially when they're kept at higher temperatures (like physiological temperature), so why is it that this doesn't occur with cells? Thanks!

| Which forces make atomic lattice so strong? Posted: 25 Feb 2020 09:32 AM PST atomic lattice materials are more durable than others (diamond for example) Why? There is low electronegativity that would keep the atoms together. Is there any other forces bonding it together and making material so durable rather than electromagnetism? Atomic lattice has covalent bonds, which are weaker than ionic ones, because of electronegativity. But it still have the most durable items. Please correct me. I am newbie in chemistry, but i am curious about it and i want to know. [link] [comments]  |

| Posted: 25 Feb 2020 09:24 AM PST If a cell is surrounded by a solution that contains a lower concentration of water, why does the water move into the cell? Wouldn't the water from inside the cell move to the outside into the surrounding solution, since there is a lower concentration of water outside? [link] [comments]  |

| What happens to an insect’s body when you spray it with insecticide? Posted: 24 Feb 2020 09:58 PM PST Obviously, it dies, but what happens internally? Whenever I spray roaches point-blank, they scurry rapidly but when you bop them, they flip over and their legs flail wildly in the air until they start twitching in their death throes. Do they get paralyzed? Are their nerves on fire? Is it the equivalent of napalm on humans? [link] [comments]  |
| Posted: 24 Feb 2020 11:43 PM PST Back in school, we had this linear timeline on how amoebas evolved into more advanced lifeforms over time. Mushrooms, plants, bacteria, fish, mammals, reptiles and birds etc. Do we all share the same origin ? [link] [comments]  |
| Can someone please explain how Cliffs are formed? Posted: 24 Feb 2020 07:49 PM PST I saw the cliffs in Moher, Ireland in a picture and I can't understand how they were formed. I looked it up, and I understand that an ancient river deposited layers of sedimentary rock, and then the ocean ate away at the bottom of the rocks. This created notches and then the rock on top of the notches crumbled into the sea leaving a vertical cliff. What I don't get is (1) how this plateau ended up so much higher than sea level before this process begun and (2) how that process would form cliffs, if there weren't already cliffs. As in, why would the ancient river's delta end up as cliffs instead of a beach? Every cliff formation video I find seems to start with the land already higher much higher than sea level, but it's not mountains in Moher, the land is flat. I'm thinking of the Mississippi River delta, I can't imagine enough sediment getting deposited to create a plateau that size and height above sea level. How would the river keep depositing sediment when the plateau becomes higher than sea level? Help pls. Lol [link] [comments]  |
