fulton county election interference case against former donald trump is on pause while he appeals to try to get the da fani willis kicked off the case. and in the case of accused gilgo beach serial killer, the man suspected of killing at least four women in long island is now being charged with murdering two more. plus, confusion and concern. the reality at the u.s./mexico border right now for those tasked with enforcing president biden's new asylum executive action. our nbc news reporters are following all of the latest developments. we begin with the deadly israeli air strike on an u.n.-operated school in central gaza. nbc's josh lederman is following that story for us. the idf says this was a precise strike on a hamas compound. what do we know? >> reporter: chris, the israeli military clearly knows the amount of criticism they're getting for this strike, coming a week after that other strike in rafah near that unrwa facility that killed dozens of people. the idf is clearly working overtime today to try to explain what they say are the circumstances of this incident. they say they were acted on specific intelligence that showed there were between 20 and 30 hamas operatives at this u.n. school, including some who they say were directly involved in october 7th. and they say they targeted the specific rooms or areas inside that school where they knew hamas operatives were holed up and that they actually had delayed this operation twice because of the risk of civilian casualties during earlier plans for an operation. but it is also very clear that in addition to those hamas operatives there were clearly civilians who were seeking shelter in areas of that u.n. compound as well. while the figures about exactly how many were killed are still not completely clear, authorities are saying a large number of them, possibly as many as half or more, were civi ans. our team on the ground in gaza saw the bloodied women and children showing up at the hospital, also the aftermath at the school, shrapnel and rubble surrounding makeshift beds. the u.n. said they are not in a position given the challenges on the ground whether israel's claim was correct that hamas was using this facility. we have heard today from a leading israeli human rights group calling this a war crime and saying even if hamas was using this facility, it doesn't justify a strike that was going to kill civilians. the question is how will this affect those delicate ceasefire talks. it certainly will not improve prospects for reaching a deal with new skepticism today coming from hamas citing contradictory comments about prime minister netanyahu about the proposal and also saying that they need to see more clarity from israel before they will sign any deal about whether this is really going to be a permanent ceasefire. they want to make sure israel is not simply going to use this as an excuse to get hostages back and then start bombing the gaza strip again. >> josh lederman, thank you. now to the georgia election interference case against donald trump which has been put on hold at least until october. nbc's lisa rubin is following this story for us. so why did a georgia court of appeals halt this case and what does it mean for the timing? >> reporter: so, chris, the georgia court of appeals halted the case because that is their standard practice where there is a criminal appeal, it is typical for them to halt all proceedings, but i should note for you that they have halted all proceedings only with respect to a certain group of defendants who are appealing judge mcafee's ruling with respect to fani willis staying on the case. the case continues with respect to a number of others, but where it comes to a trial before election day, it is almost a complete certainty that that won't happen. argument is not scheduled until october, chris, and so this is one more case that our viewers can count on not happening before november. >> lisa rubin, thank you. we go to long island now where two new murder charges have just been brought against the suspect accused in the gilgo beach serial killings. nbc's antonia hilton is following this story for us. rex heuerman was back in front of a judge today. what happened there? >> reporter: well, chris, he is now facing these two additional sets of charges for the killings of jessica taylor and sandra costia. these are killings that go back to 2003 and 1993 and that last date is important here because it really opens the window here, the amount of time, our understanding of how long this string of killings was happening here on long island that caused so much fear and concern for decades here. and we also learned pretty astonishing information about the information they had gathered while doing searches of his home, additional dna evidence that they have confirmed and really the most shocking thing we found out today, chris, was that authorities found a word document from the early 2000s in which rex heuerman had been keeping clear columns with mistakes he had made in murders in the past, ways in which he was going to improve going forward, dump sites where he might leave bodies in the future, even target names. so this is the kind of evidence that is frankly a prosecutor's dream because it speaks to intent, motivation certainly, and it appears he was almost spelling out what he was planning to do to these women right there on a document that they recovered on one of his computers at home. i mean, this is really what you would call ground breaking. take a listen to some of what was shared today in the da's presser. >> we said that the case was not over. we said we were going to continue to investigate the case of the gilgo four and find more evidence. we've done that. my office along with our partners are not going to stop. this case continues. >> reporter: the reality here, though, is, of course that is correct actually the majority of the killings have not yet been solved or even conclusively attached to this suspect. so that leaves the door open here. do they continue investigations? do they go back and do additional searches and keep adding one charge after another, or do they move to a trial now? as many of the victims' families want, get this guy officially behind bars. that's really the question here in the community. people have fought for so long for there to be this level of information, interest and urgency behind this case. many of these victims they came from low-income backgrounds, many of the women were sex workers. that is what left people to concerned that for a time authorities weren't taking this seriously enough, weren't taking enough action. the question is what happens next? >> antonia hilton, thank you for that. let's go to the southern border now and the confusion on the ground after president biden's new executive action. julia ainsley is reporting on that for us. i understand three border agents spoke to nbc news about this. what did they say? >> reporter: that's right, chris, i'm just back from south texas and there is a lot of confusion there about how exactly how they should deal with immigrants who cannot claim asylum since that ban went into effect at midnight on wednesday, but cannot be deported. as you know, we can deport about over 60 -- the u.s. has deported about 60,000 migrants per month over the past year, that is a high -- higher than anything they've soon in the past decade, but that is still less than double the amount of migrants who cross the southern border per month. so what will they do unless they can get more funding for planes, for detention space, and to get countries like venezuela and china to take back their nationals who right now they refuse in large part to take back. so there's a lot of concern about overcrowding because, remember, chris, this was supposed to come as part of that bipartisan bill that was negotiated in the senate, but since it wasn't passed by congress it doesn't come with more money, more manpower, more detention space or more authority and they're worried about what this will actually look like if those numbers get very high and could that lead to overcrowding, and if it does will they be allowed to just release these migrants even though they can't claim asylum? what will happen to those people? confusion among the migrants themselves wondering how this will affect them and whether or not this is good news or bad news. >> julia, thank you. in 90 seconds, the effects of global warming on full display as triple digit temperatures batter states out west and summer hasn't even officially begun yet. what more should we be doing to fight climate change? an expert will join me next. o fight climate change an expert will join me next. so, i didn't think i needed swiffer. until... i saw how easily it picked up my hair every time i dried it. it only takes a minute. look at that! the heavy duty cloths are extra thick for amazing trap and lock. even for his hair. wow! and for dust i love my heavy duty duster. the fluffy fibers trap dust on contact up high and all around without having to lift a thing. i'm so hooked! you'll love swiffer or your money back! [introspective music] recipes. recipes written by hand and lost to time. are now being analyzed and restored using the power of dell ai. ♪ today, at america's beverage companies,... ...our bottles might still look the same... ...but they can be remade in a whole new way. thanks to you... we're getting bottles back... and we've developed a way to make new ones from 100% recycled plastic. new bottles - made using no new plastic. you'll be seeing more of these bottles in more places. and when we get more of them back... ...we can use less new plastic. see how our bottles are made to be remade. a rare and deadly string of powerful tornadoes ripped through the northeast and midwest yesterday injuring at least five people in maryland and killing a toddler in michigan. high force winds uprooted an enormous tree, crashing it into a suburban home outside detroit where a 2-year-old was sleeping. he was pronounced dead at the scene. the child's mother was also injured, but his 2 week old sibling and grandmother were unharmed. more trees toppled in maryland where officials say one of the people they brought to the hospital suffered a traumatic injury. and today parts of nevada and arizona are scorching under temperatures that feel hotter than 110 degrees. this heat wave is just the beginning of a summer that the national weather service warns will be relentlessly hot. we're fresh off a year of record-breaking global heat with no end in sight and there is a new study out that warns weather-related power outages have nearly doubled this decade, compared to the last one. and in dangerously hot temperatures blackouts can be deadly. it all raises the risk of what one expert calls a heat wave scenario that keeps climate scientists up at night. joining me now msnbc political analyst basil smikle. full disclosure here, i don't know if it's the heat out west, a couple of the other people we were hoping to have on this panel we have not been able to get their signals together, but i do want to ask you about the politics of this. i was just thinking because we're doing this ceremony at d-day that when i was covering the white house and at the end of president obama's term there was a great feeling of accomplishment, the paris climate accords had been agreed upon. not a solution, but a huge step forward that now we've gone away from. do you think as more and more people feel the very real world effects on their every day lives something is going to change here? >> well, you would want that to happen, right, because what climate change does is touch multiple areas of policy in our lives. i had a conversation with transportation secretary pete buttigieg some months ago and we were talking about the challenges even for rails. there was an accident in new york where a commuter -- commuter rail line had to close down because of a landslide, a mudslide, after heavy rains. so when you think about how many areas climate change touches and how it will impact our lives quite considerably over multiple facets of our lives, it will become, i think, a bigger part of our day to day political conversation. what i would also say is that young people are very aware of this because we are, as an older generation, giving them something that they will inherit and have to maintain, so the key is let's not -- let's not screw it up and give them something that they can actually -- they can actually survive in. >> i think the reality is some of these studies is that people of a certain age, 50, 60, 70, thought, well, i'm worried about my children, my grandchildren, but it's not likely to hit me in the way that some communities frankly are already experiencing it, and when we talk about communities, communities of color, people who live in low-income communities are often the ones who are hit hardest. for example, let me give you just one thing, the cost of cooling your home is now at a ten-year high. so even if you have air conditioning, and many low-income families do not, it's going to be pricing out or we've already seen reports in some local newspapers in those communities where people are having to make a choice, right? you have to choose am i going to pay my rent or am i going to be able to cool my apartment? are we viewing this as a country with as much urgency as is required? >> not at all, particularly when, as you talk about the environmental justice impacts of climate change. when we think about, for example, the fact that, you know, we don't think about the united states as an imperialist country much but it does have territories, puerto rico, the virgin islands, and think about the weather concerns and rolling blackouts that puerto rico session experiencing because their infrastructure -- there are people that are sort of toying with their infrastructure and the united states not being really serious about strengthening that. when you also think about what's happening in our prison community, for example, across the country, the fact that as you talk about air conditioning in homes, what's happening in our prison system, for example, and how are folks who are incarcerated being treated in these extreme heats dealing with this extreme weather? >> and to be fair the staff, too, because when you look into this, because it's happened, for example, in texas where they were trying to get more air conditioning in and it didn't happen, the tensions it creates when everybody is, frankly, overheated. >> that's right. >> literally and -- >> that's right. >> -- metaphorically, it can cause real problems. >> i will say quickly i was just in new orleans, one of my favorite places on the planet, and i think about the impacts of katrina on new orleans and the fact that so many of my friends there, african americans, left because the infrastructure needed to be developed and strengthened, and have not yet returned. so it actually has an impact on changing the geography, but also the cultural sort of foundations of communities in which people of color reside. so these effects are wide-ranging. >> i also want to bring in jeff goodell he is author of "the heat will kill you first." you have been on the forefront of the warnings and storms since we were talking about infrastructure just moments ago killed power to over a million households just in houston last month and they didn't get all the electricity back until five days later. and you noted that it was really lucky that it was much cooler at that time. so i want to ask you based on your research if something like that happens, if the power goes out during a week like this one in communities where the temperatures are in triple digits, what are we going to see? >> we're going to see mass chaos and we're going to see a lot of deaths. my piece talked about a paper that was published a year or so ago by some well-known heat researchers looking at what would happen in three different cities, detroit, atlanta and phoenix, if there were a five-day power blackout, two days of complete blackout and then three days of restoring the power during an extreme heat event. the results, especially for phoenix, were really shocking. phoenix is a city that has 99% air conditioning, right, and so you would think it would be less vulnerable, but, in fact, because of the dependence upon air conditioning, if the power went out in phoenix for five days, there would be the study estimated -- and they made the point that this was conservative -- 800,000 emergency room visits and over 13,000 deaths, which is difficult to bend your mind around. but it really proves -- or shows the point that air conditioning for all of its sort of comforts that it brings us, it's also like a sort of dem a close hanging over the heads of these very hot cities. >> i'm also joined by msnbc medical contributor dr. vin gupta. vin, jeff -- you just heard him talk about this in those dreaded scenarios. hospitals wouldn't be equipped to handle it. hundreds of thousands of visits. we know heat-related deaths are rising, they were up 88% in 2022 compared to just 2000. look at these pictures. hospitals in vegas are prepping human ice immersion bags creating this new response protocol for the summer ahead but i wonder can we prepare enough? give us a sense of what this could mean for hospitals and public health, vin. >> chris, this is critical to point out and to talk about. these solutions aren't scaleable. the ice immersion techniques we're seeing in phoenix, seeing in places like las vegas as you pointed out, not scaleable. we can do it patient by patient maybe at the health system level, but the idea that we can -- this is a solution to what's happening in phoenix, it's not tenable. we're also seeing that there has been a 90% increase in heat-related deaths just in the last four years over what we saw at the turn of the century, coupled with now forecasts, chris, across the world, 370% increase we are forecasting in heat-related deaths by 2050. this is now something that we just have to contend with. there is no averting the worst of it. how do we contend with this? how do we make sure we have public infrastructure that's ready for what's happening in the southwest? that's one. and then, two, also the impact of heat on food. we now know 500 million people across the world will be at risk of starvation because of heat-related issues. so this is not just heat exhaustion, the impact of heat on the body, it's also what happens to our food supply. >> so let me go back, if i can, jeff, because in the lead in i said that one expert called this a heat wave -- said there was a heat wave scenario that keeps climate scientists up at night. you were the person who said that. what that we haven't touched on right now, real world, keeps you up at night? >> well, i think just the understanding of what's causing these heat waves. i mean, you know, these heat waves are being caused by our continuing to burn fossil fuels, putting c02 into the atmosphere. that is what's raising the heat, causing a more chaotic climate. and i don't think that, you know, we've got the message about that yet. i don't think that we understand the urgency of what we're talking about here, that there are literally tens of thousands, hundreds of thousands of lives at stake. so when we think about dealing with the climate crisis, what's really important is speed, is grasping the situation quickly, getting off of fossil fuels as quickly as we can, preparing for our infrastructure for this new climate that we're living in. >> well, let me ask you, then, dr. gupta, because there are going to be tens of millions of americans who are going to face this this summer, there are people as we were talking about with basil, the income inequality issue. we know that those most vulnerable are those
