> and prosecutors learned that michelle did more than send text messages to conrad, as deadly carbon monoxided the truck, michelle was talking on the phone. >> there were two phone calls after the last text message. one from him to her. 41 minutes and then, one from their to him for over 42 minutes. >> but how would they ever know what was said on the calls. detectives poured over the text messages. and they got the answer. >> low and behold, there was text messages to her friends describing what the phone conversation was like. >> the detective said a message that michelle sent her friend explained it all. sam, his death is my fault. like honestly, i could have stopped him. i was on the phone with him, and he got out of the car because it was working and he got scared. and i -- told him to get back in. >> and as much as we were in shock about her language prior to that, once we read that, that was really disturbing. >> prosecutor flynn said another text message to that friend made it clear that michelle knew what she had done was wrong. >> she said, sam, i just found out from his mother that

flourishing seaweed will bring back fish and help absorb carbon monoxide.t could be a win-win for both the planet and sushi lovers. >>> our last story focuses on an alternative source of food. industrial live stock farming accelerates climate change by releasing huge amounts of methane gas. but there is another abundant source of protein on this planet that can be produced with much less harm to the environment. insects. the only challenge is getting more people to eat them. here is one such effort in western japan. >> these crackers hit the market in may. they may look like ordinary snacks but they are made of something different. cricket powder, basic potato starch. at first they taste like crackers. the more you eat the sweeter they get. a company provides the cricket powder using the crackers. this business was started by this man. he is an insect ecology professor at the university. his team is raising 700,000 crickets. they are big ones. over time the team is raising them from eggs. in a month they'll be three centimeters long. the fast growth makes t

>> i don't know if anybody has ever explained to you that breathing and carbon monoxide is not healthy. >> reporter: this instagram video shows a woman concerned about what should be unhealthy levels of co2 or carbon dioxide from breathing in your own air. that too is a myth according to dr. blumberg. >> people can get plenty of oxygen, they don't become hypoxic, it doesn't accumulate carbon dioxide. and these are perfectly safe. >> reporter: he says surgical facemasks or cloth face coverings have gaps and allow for plenty of air circulation. >> neurosurgeons and heart surgeons and nurses in the or are wearing their masks for 4- 12 hours a day, they are not accumulating toxic gases, they are not getting lung damage from this. these are really smart people. >> reporter: dr. blumberg says wearing face coverings. social distancing is the best way to protect ourselves and others. >> the primary transmission of covid-19 is the respiratory route. it makes sense that wearing a mask would block the droplets, so that does result in decreasing transmission by about two thirds if you wear a mask.

. >> i heard a sound bite of a woman saying we are inhaling dangerous carbon monoxide. this is where we are. >>> another myth is that cotton masks aren't woven tightly enough to prevent coronavirus. >> here is the weave under a microscope compared to droplets. none of these will stop 100% of particles from escaping, but any show this will help blocking power. it is how fibers are layered and stacked. this is more like a rat's nest than a weave so a change link fence can't stop mosquitoes, but two chain link fences can stop mosquitoes if they are the size of tennis balls. >> a mask is not intended to be a magic device block everything coming out of everyone's house. but just like the layers of a surgical mask or n95 mask can help with that. other things like social distancing, washing hands, staying home. this is multistrategy just like layers in the mask. >> a new study found that a cloth face covering should have at least two layers, preferably even three to be effective. what do you think about that? >> as joe says, having layers works better. it blocks the droplets g

the bay area saw a 32% reduction in carbon monoxide emissions. tomorrow county leaders in the bay area air quality management district will sign a cut the commute pledge. the goal is to get businesses to increase employees working remotely when possible. >>> well, a warm stretch that will be coming to an end i believe tomorrow. have i got that right, rob? >> yeah. you know, and we're starting to see signs of change right now, including around dublin with temperatures earlier than 100 degrees. as hot as 102 today. look at that. 67 degrees. some signs of cooling there. san francisco, no fog just yet. low clouds starting to form off the golden gate. we're at 58 degrees. the winds on shore there. in san jose, mainly clear skies. a high earlier of 90 degrees and san jose should see those temperatures drop into the mid-80s for tomorrow. you take a look at the temperatures. 50s and 60s across the bay. walnut creek still looking at 70s. you really haven't seen the strong push of southerly wind and low clouds into the north bay just yet. so the real cooli

there's air pollutants within natural gas, such as carbon monoxide and nitrous oxide, which are linkedto both various chronic and acute health impacts. this includes respiratory illness, cardiovascular disease, and there's also just a growing body of literature that shows that natural gas triggers asthma attacks, and it might actually cause asthma in otherwise healthy children. natural gas impacts safety and resilience. in the united states, on average a gas or oil pipeline catches fire every four days, results in an injury every five days. there's an explosion every 11 days and leads to a fatality every 26 days. we saw those examples last year in san francisco. the hall of justice needed to be evacuated and also the fire that erupted around parker avenue and gary boulevard that destroyed buildings. you know, natural gas provides the city with resilience eliminating fires and earthquakes, and for electricity about a week. and lastly, for low-income communities and communities of color that are more likely to suffer from asthma and other health impacts of poor air quality, zero emission

remarked as to whether or not we can execute people with the way they put down animals, or give them carbon monoxide, or something like that. and all of the extensive focus that we as a society put on this matter, and i want to put this into the context of another small population of citizens who are innocent. they are administer drugs in hospitals that are known to be fatal. but because the drug manufacturers don't do a very good job of filtering out people who had adverse reactions, these citizens and up dying a very painful and horrendous death. kind of like a long drawn out execution, for which there are no protocols for putting them down for example, and ending their suffering. >> thank you. the basic question is can states be held accountable for the methods they use to administer the death penalty? >> absolutely. in recent years the supreme court has decided to cases challenging lethal injection protocols that neither of which courts found a problem with. each of those cases had justices dissenting from it. the supreme court has just in his last month, granted review on another case in which

autopsy finding that vashti seacat had no soot in her lungs, in her airways, and that there was no carbon monoxidea key piece of evidence for the prosecution, because what it showed, what the jury could infer from that was that vashti seacat didn't breathe in any smoke. and if she didn't breathe in any smoke, the fire was set after -- >> after she was dead. >> -- she was dead. >> and something else -- weird little detail. and yet, according to the prosecution, it was telling. when she died, vashti's bladder was quite full. >> there probably would have been a urinary urgency or the needing to go to the restroom. >> and the importance of that for the evidence is that the claim from brett seacat is that vashti is walking around the house setting these fires, holding her breath, not breathing any smoke while she has a strong urge to urinate. that doesn't make sense. that's something that the jury needed to decide whether or not in their common sense and experience, whether they thought that made any sense at all. >> just another point to add to the unlikelihood of this whole story that he was telling.

sydney killing a british businessman and his family may have had his flying ability impaired by carbon monoxideeopen for business, but it hit a record of more than 8,000 virus cases a day on wednesday, up from about 2,400 two weeks ago. mr abbott said face coverings will help slow the spread of the virus. one of the best ways to keep businesses open whilst slowing the spread is for everyone to wear a face covering like this when they go out. medical studies have shown that wearing a face covering slows the spread of covid—19 and it protects you and your family. let‘s take you straight to edinburgh where the first minister, nicola sturgeon, is holding the daily coronavirus briefing. we do know we are waiting to see how all the nations and regions respond on the question of travel, international travel. we have heard that england has announced some easing so let‘s now hear from nicola sturgeon. good afternoon, thank you for joining us again today. i will start with the usual update on the covid—19 statistics for scotland. i can report today that an additional 12 positive cases were confirmed yest

associated with increased incidence of asthma and respiratory illness as well as the risk of carbon monoxideourse fire. all of those reasons are why it has been a priority for the supervisor to work on building electrification. last april, we passed unanimously, the board of supervisors, a resolution to declare a climate emergency in san francisco which committed san francisco to doing our part to limiting global warming emissions to below 1.5 ° celsius, the level we know we have to avoid, we have to keep in order in order to avoid the most severe impacts of climate change. we advanced. we moved on from that to pass an ordinance last year that requires natural gas buildings to achieve a higher energy efficiency standard and also approve the ordinance that the director mentioned requiring all electric construction in our municipal projects as well earlier this year. today's ordinance is going to take the next step to ban natural gas from all new construction projects starting for those that apply next year. the ordinance does -- cyndy will get into some of the details here, but i want to be c
