two news at 730. >> you remember that alert. it followed that big earthquake up in humboldt county. it left many people unsure what to do. thanks so much for joining me tonight i'm heather holmes. happening now. emergency officials in san mateo county meeting with residents. our lamonica peters live now with a look at what was discussed tonight. lamonica. >> heather. supervisor ray mueller says this meeting was an opportunity to hear from the community and talk about what went well and what could have been done better during the tsunami warning now. mueller led the discussion along with other stakeholders, including emergency management and first responders. now, the emergency management team first talked about why there was a tsunami warning, explaining that there had been a 7.0 earthquake. they then also explained why the sirens didn't go off that day. they say it was a collective decision made by multiple counties and agencies to not sound the sirens, because the

impact would not be significant enough in this area, and they wanted to avoid panic. people also talked about not knowing what low lying areas were during the evacuation. emergency management and mueller acknowledged that there was a lot of confusion and panic for people, and that's what they want to avoid when there's another warning. >> many people didn't know where the low lying areas were that they were supposed to leave, and what they saw around them were individuals leaving, which led to panic because they didn't have the information to know that where they were was safe. and so one of the things the county and part of that was caused because the state website crashed. >> now, again, one of the main takeaways from this meeting is that the messaging needed to be better and clearer, so that people can understand what they need to do. now, supervisor mueller says that they plan to work on having better outreach, as well as creating their own county website, which should be up and running by february.

>> heather. yeah, a real opportunity here to learn some lessons moving forward. i know you're going to stay at the meeting and have a much more detailed report coming up tonight at ten and 11. lamonica thank you. well, the cleanup continues across san francisco after that severe storm that we had over the weekend that triggered the city's first ever tornado warning. now, as we all know, a tornado never materialized. but the powerful winds did topple trees all across the city. the recreation and parks department has tallied up 98 downed trees in all, with 74 of those trees right here in golden gate park, city officials say. although the damage was extensive, the best news is no one was hurt. >> i'm pretty confident that our staff is well prepared for these kinds of impacts. you know, our arborists and gardeners work year round to assess the health of trees. so, you know, whether there is another storm coming. we are well prepared. our advice to people is really to avoid unnecessary travel during

extreme weather, and also to be careful when walking near trees, especially in parks. and it's also important to note that even healthy trees can fall during these strong wind gusts that we have so far. >> there is no estimate on the cost of the damage, but as you see, there are a lot of trees down and large ones there in golden gate park. well, hundreds of bay area workers are on the picket lines heading now into the holidays. amazon. >> amazon. >> amazon. workers nationwide and in san francisco. walking off the job today. distribution warehouse workers are asking for pay increases, better benefits and to be recognized in the union. they say they gave amazon a december 15th deadline, but they say they were ignored, refused to do that. >> they refused all the other deadlines that we've set for them. so now they've left us with no choice but to strike. >> amazon accused the teamsters of coercing and threatening

amazon employees to join the strike. across town, workers at the marriott hotels began voting on a new contract offer that was just extended to them. workers say it appears to be a good deal with medical benefits and wages, where they need to be, just in time for the holidays. hilton and hyatt workers in san francisco remain on the picket lines. a new at 730 tonight. an environmental group is suing the port of oakland over its proposed expansion plans. there are plans for a brand new terminal and improvements to parking and international arrivals. this lawsuit, which was filed by communities for a better environment, claims that the environmental impact report understates the true impacts of the expansion to air quality, noise and traffic. it calls for a new environmental analysis. the port of oakland, though, saying in a statement that the project will modernize the airport's facilities to meet the region's travel needs. it added. quote the final the final environmental impact report was certified by a unanimous vote by

the oakland board of port commissioners back on november 21st of this year. the eir is a product of years of careful study, community outreach, and careful deliberation preceding the november vote. okay, taking a live look now at sfo that you see here where holiday travel is in full swing. but despite the holiday rush. united airlines flight attendants walking the picket lines at sfo and at other airports all across the country. what do we want on track? >> where do we want to go? where do we want? >> they are gearing up for a possible strike as they negotiate for better pay. the association of flight attendants is calling it a day of action, and this follows their overwhelming 99% strike authorization vote that happened back in august. in a statement to ktvu. united airlines says we are eager to reach the industry leading agreement with our flight attendants that they deserve. united is offering pay raises of 22.5%, new boarding pay and many other improvements. the federal mediation process,

requested by the association of flight attendants, is expected to resume early next year. okay. efforts to recruit former oakland congresswoman barbara lee to run for mayor are really ramping up today. a group of community leaders published an open letter calling for lee to run. the letter was signed by 25 community leaders and organizations saying, quote, oakland is a city that is facing a crisis of leadership. and the letter says that barbara lee is the person they think could bring people together. >> she brings a level of stature. she can get anybody in the world on the phone, and oakland is going to need a lot of help to get out of this situation that we're in. it's one of the first times you have a coalition of business people, labor people, community people, longtime civic leaders, longtime residents, council members who don't always agree on issues. >> and that gentleman who helped spearhead the letter points to the diverse group of people who signed it. and that includes nikki fortunato bass, who you see here. for now, though,

congresswoman lee has not commented on the letter. but when we spoke with her earlier this month, she did tell ktvu that she was thinking it over, meaning that run for mayor right now, though, she says she is listening and talking to people, listening to what they care about and what they want and seeing if i'm the type of a person that could help and again, make life better and make every community better. >> so i'm still pondering it. >> the oakland city clerk is handling the special election today. the office posted the list of 11 candidates so far who have already submitted paperwork. that includes wendy adams, tyrone jordan, peter liu, mindy petchenik, fabian robinson, andrea smith, derek leon, sue elizabeth sweeney, lauren taylor, renea webb and larry young junior. a lot of names on that list. all right. 19 year old brothers from san carlos just won an award for their invention to help improve the quality of our oceans. and

taking a break from college to join us here at ktvu. thank you so much. tell us right now what is happening to the oceans. what's threatening them? >> yeah. so what we see in our oceans is a troubling shift due to rising carbon dioxide emissions, leading to a phenomenon called ocean acidification. so our waters is increasing in acidity, which weakens our coral reefs. and this is not just an environmental problem. it's an economic one. as tourism suffers due to shrinking coral reefs as well as aquaculture is threatened due to reduced marine life. >> okay, so we're really seeing the impact of all of this on the ocean. so. so tell us about your invention and how it addresses the problem. >> yes of course. so for our invention we created keto bio filters to break it up. keto stands for keto morphe, and it's the type of algae that we chemically modified, specifically altering two enzymes. we then engineered bio filters that implement this modified algae into the oceans, featuring a gps infiltration

system with our solution. it's low tech, so meaning it's sustainable, cost effective, and highly scalable compared to the highly intensive, pervasive coral propagation projects that we see today. >> okay, we're looking we're showing the audience now, this algae that you were talking about, how did you even come up with this idea? >> yeah. so a large part of our inspiration came from a trip that we went to australia for in 2017. we witnessed firsthand there the impacts of ocean acidification, specifically in the great barrier reef. but all that started when we were kids. we grew up around animals. we actually had a zoo. growing up, we owned exotic pets ranging from geckos to tortoises to even skinks. >> wow. >> that's amazing. so i understand you started though working on this project when you were sophomores in high school. yeah. now you're 19 at penn state. walk me through the process about getting to this point. >> yeah. >> so we're actually studying at the university of pennsylvania.

and basically so we started this off as a science fair project, but pitching it or transitioning from science fairs to business competitions, we were able to get patent for our technology. and ever since, we've been continuing to develop research and continuing our development of the invention. >> okay. >> and then you just got this big award right for it. tell us about that. >> yeah. we were so honored and thrilled to be recognized by the ipo foundation. essentially, ever since coming up with this creation in sophomore, we couldn't imagine where it has led us and still continuing this project till today. our long term plan is to eventually work with governments and environmental agencies to bring the solution and technology a globally to help implement it in our oceans. >> yeah, because i think what's really important is that you mentioned that this is something that is affordable, but is it also scalable, do you think? >> yes, i think since it's due to the low tech nature of our solution and it's also naturally done, we believe that it's

scalable specifically to developing countries where we can implement this solution in the ecosystems that really need it. >> okay. >> so what's next? and are you getting people interested in this? >> yeah. >> so as full time college students at upenn, we spent our free time continuing the research and development. but a big part of our time right now is continuing to pitch our ideas to investors, as well as entering in even more competitions so that we're able to secure the funding to continue doing our research, because this does require a lot of work. >> i mean, you have patents here, right? >> yes. yeah. so we got a patent from a competition that we won, and they were able to sponsor us through that process. and even with the ipo education foundation, they provided us with mentors and coaches to go through this process of pitching and working with these investors as well. >> well, it's just a real pleasure to meet both of you young people who are really trying to make the world a better place. i appreciate that. thanks again for coming in and good luck. you have to keep us

posted on what's next for you guys. okay. and sorry at upenn. i got it now and hope that you have a wonderful holiday with family here at home. and good luck when you start back to school. okay. thank you, thank you, thank you. okay, now let's head on over to meteorologist roberto gonzalez. i always say we have some of the brightest minds here in the bay area. >> i'm their biggest fan. do you guys think you can do anything to help us out with this tsunami warning that we are experiencing here? and some difficulty. we'll talk. we'll talk after the show. hi, everybody. good evening to you. boy, was it a cool day across the bay area. you can clearly see where the fog did not clear out today. where it just hung out over the valley, 48 degrees. that's as good as it was today in livermore. that was the actual high temperature. how about 47 degrees in vallejo? back in through american canyon. it was 49 degrees in fairfield and 48 in fremont through milpitas, compared to 63 in san jose, where it did clear out live weather camera looking out toward san francisco. visibility is at ten miles right now. we do not have any reports of fog, but
