THANK YOU.

>>> IT'S NOT JUST HOT, IT'S DANGEROUSLY HOT IN PARTS OF SAN DIEGO COUNTY.

THANKS FOR JOINING US.

I AM JOHN CARROLL IN FOR MAYA TRABULSI.

EXCESSIVE HEAT WARNINGS IN EAST COUNTY RUN THROUGH NEXT WEDNESDAY .

KPBS REPORTER ANDREW DYER HAS MORE ABOUT WHAT'S BEING DONE TO HELP KEEP PEOPLE FROM OVERHEATING.

>> Reporter: COUNTY OFFICIALS ARE ENCOURAGING PEOPLE TO STAY SAFE AS DANGEROUS HEAT CONDITIONS PERSIST IN AND AROUND SAN DIEGO.

EXCESSIVE HEAT WARNINGS FOR THE NATIONAL WEATHER SERVICE ARE IN EFFECT IN THE SAN DIEGO MOUNTAINS THROUGH SATURDAY NIGHT AND IN THE DESERTS THROUGH WEDNESDAY.

SHE PUTS THREE-YEAR-OLD SAGE IN A STROLLER.

DEALING WITH THE HEAT JUST COMES WITH LIVING IN EL CAJON.

>> TODAY WE JUST WENT TO THE LIBRARY OVER HERE.

SHE PLAYED WITH TOYS AND I JUST SAT BY AND WATCHED AND STAYED IN THE LIBRARY TO GET SOME COOL AIR.

VERY NICE IN THERE ACTUALLY.

>> Reporter: PUBLIC LIBRARIES AND COMMUNITY CENTERS THROUGHOUT THE COUNTY ARE SERVING AS COOLING ZONES DURING OPERATING HOURS WHERE EVERYONE IS WELCOME TO ENJOY COOL AIR CONDITIONING INDOORS.

SHE SAYS SHE APPRECIATES THE LIBRARY FOR WHAT THEY OFFER FOR CHILDREN, ESPECIALLY ON HOT DAYS.

>> BECAUSE THEY HAVE FREE ACTIVITIES AND STUFF THAT INTERESTS HER AND KEEPS HER ENGAGED.

LIKE I SAID, IT'S FREE.

>> Reporter: OFFICIALS RECOMMEND AVOIDING ALCOHOL AND SUGARY DRINKS IN FAVOR OF WATER AND TO AVOID UNNECESSARY ACTIVITIES OUTDOORS DURING THE HOTTEST PARTS OF THE DAY.

PETS AND CHILDREN SHOULD ALSO NEVER BE LEFT UNATTENDED IN A CAR.

PEAK HEAT IS EXPECTED SATURDAY WHEN TEMPERATURES COULD TOP OUT AT 105 DEGREES.

DESERTS IN SAN DIEGO COUNTY AND THE COACHELLA VALLEY COULD WILL BE COOKING WITH TEMPS HIGHER THAN 120 DEGREES EXPECTED.

FOR MORE INFORMATION AND HELP WITH FREE TRANSPORTATION TO A COUNTY COOLING ZONE, PEOPLE CAN CALL 211.

>>> NOW AN UPDATE ON THE McCAIN FIRE IN BOULEVARD.

CREWS ARE CONTINUING TO MAKE PROGRESS.

CAL FIRE SAYS THE FIRE IS NOW 87% CONTAINED.

IT STARTED MONDAY AFTERNOON NEAR McCAIN VALLEY ROAD AND INTERSTATE 8.

THE FIRE GREW FROM 1300 ACRES TO NEARLY 1600 EARLY YESTERDAY.

THE FIRE ACTIVITY REMAINS LOW ACCORDING TO CAL FIRE.

>>> THOUSANDS ARE EXPECTED TO PACK OUR BEACHES THROUGH THE WEEKEND, BUT THERE IS A BEACH HAZARD YOU NEED TO BE AWARE OF BEFORE HEADING OUT.

IT IS IN EFFECT THROUGH SUNDAY AFTERNOON.

HIGH SURF PEAKED TODAY AND WILL LAST THROUGH TOMORROW.

WAVES ARE EXPECTED TO HIT 3 TO 5 FEET WITH SETS UP TO SEVEN FEET IN SOME AREAS.

THERE IS ALSO AN INCREASED RISK OF RIP CURRENTS.

IF YOU GET CAUGHT IN A RIP CURRENT, THE FIRST THING TO DO IS FLIP OVER AND FLOAT, THEN SWIM PARALLEL TO THE SHORE.

AS ALWAYS, LIFEGUARDS RECOMMEND YOU SWIM NEAR A LIFEGUARD TOWER.

>>> WE ARE STILL LOOKING AT MAJOR INTERIOR HEAT OVER THE COURSE OF THE NEXT COUPLE OF DAYS AS WE WILL CHALLENGE RECORDS.

IN FACT, QUITE A FEW RECORDS AS WE GO THROUGHOUT THE UPCOMING WEEKEND.

ALONG WITH THAT, DRY CONDITIONS ARE GOING TO BE CONTINUING.

COULD WE SEE CHANGES WITH REGARDS TO THE EXTENT OF THE HEAT AS WE HEAD OUR WAY INTO NEXT WEEK?

WE WILL LET YOU KNOW OF THOSE CHANGES AND ALSO TALK ABOUT THE POTENTIAL FOR SOME CLOUDINESS ALONG THE COAST COMING UP IN JUST A BIT.

>>> IT HAS BEEN TWO MONTHS SINCE PALOMAR HEALTH MEDICAL GROUP 'S COMPUTERS WENT DOWN.

OVER THE HOLIDAY, P HMG SENT AN EMAIL NOTICE TO KPBS SAYING HACKERS CAUSED SOME RECORDS TO BE DELETED AND PATIENT INFORMATION COMPROMISED.

KPBS NORTH COUNTY REPORTER ALEXANDER WHEN HAS MORE.

>> Reporter: THIS NEW INFORMATION COMES AFTER A CLASS- ACTION LAWSUIT WAS FILED ON BEHALF OF THE PATIENT ON JUNE 24th.

ATTORNEYS ALLEGED NEGLIGENCE ON THEIR PART OF VIOLATION OF THE STATE GOAL MEDICAL CONFIDENTIALITY ACT, CUSTOMER RECORDS ACT, AND THE RIGHTS TO PRIVACY, AMONG OTHER CLAIMS.

THE SUIT IS SEEKING MONETARY DAMAGES.

ACCORDING TO PALOMAR, THE BREACH HAPPENED BETWEEN APRIL 23rd AND MAY 5th.

SINCE MAY 5th, THEIR COMPUTERS HAVE BEEN DOWN AND DOCTORS DO NOT HAVE ACCESS TO PATIENT RECORDS INCLUDING PRESCRIPTION INFORMATION.

THAT HAS BEEN FRUSTRATING FOR PATIENTS LOOKING TO GET THEIR PRESCRIPTION REFILLED.

PALOMAR SAYS THEY DON'T KNOW HOW MANY RECORDS WERE COMPROMISED IN THE BREACH, BUT THAT IT INCLUDES NAMES, DATES OF BIRTH, SOCIAL SECURITY NUMBERS, MEDICAL HISTORY, AND HEALTH INSURANCE INFORMATION.

I SPOKE TO A CYBER SECURITY EXPERT WHO SAYS THAT IS QUITE ALARMING.

TONY SAYS PATIENTS SHOULD ASSUME THE DATA HAS BEEN BREACHED.

>> YEAH.

THIS IS TWO MONTHS SINCE THE BREACH HAPPENED.

CHECK MEDICAL INSURANCE CLAIMS.

THAT NOBODY HAS BEEN MAKING FRAUDULENT CLAIMS IN THE LAST TWO MONTHS.

I WOULD LOCK MY CREDIT FILE.

ALL THAT MEANS IS NOBODY CAN ACTUALLY USE YOUR SOCIAL SECURITY NUMBER OR YOUR PERSONAL INFORMATION TO GAIN ACCESS TO CREDIT.

>> Reporter: BECAUSE HACKERS WERE ABLE TO DOWNLOAD AND DELETE RECORDS, CYBERSECURITY PROFESSOR NICHOLAS SAYS THIS COULD BE A CASE OF DOUBLE EXTORTION RANSOMWARE.

>> THAT LEADS ME TO BELIEVE THE ATTACKER WAS ATTEMPTING TO DELETE THE DATA AND THEN SAY, HEY, IF YOU WANT DATA BACK, YOU ARE GOING TO HAVE TO PAY US.

ONCE THEY GET THE DATA BACK, THEY WILL SAY, OKAY, IF YOU DON'T WANT US TO RELEASE THE DATA, THEN YOU HAVE TO PAY US AGAIN.

THAT IS BECOMING VERY COMMON.

>> Reporter: SMALL HEALTHCARE SYSTEMS LIKE PALOMAR DO NOT HAVE THE FINANCIAL RESOURCES OR MANPOWER TO RECOVER THE DATA QUICKLY.

PALOMAR SAYS ANYONE WITH QUESTIONS ABOUT THE BREACH CAN CALL THE NUMBER ON YOUR SCREEN , 888-829-5736.

IN THE NEWSROOM, ALEXANDER.

KPBS NEWS.

>>> THE DAYS AFTER INDEPENDENCE DAY ARE ONE OF THE BUSIEST TIMES OF YEAR FOR THE SAN DIEGO HUMANE SOCIETY.

THAT'S BECAUSE THEY TYPICALLY SEE AN INFLUX OF LOSS DOGS.

LAST YEAR THE HUMANE SOCIETY SAYS 273 STRAY DOGS CAME INTO THEIR SHELTER BETWEEN JULY 4th AND JULY 7th.

JUST 76 OF THEM WERE RECLAIMED.

THIS YEAR THEY ARE EXPECTING AROUND 300.

THEY ARE BUSTING OUT CRATES AND KENNELS IN THEIR CONFERENCE ROOM IN ORDER TO MAKE SPACE.

>> BECAUSE IT IS TOUGH BECAUSE NOBODY WANTS TO SEE AN ANIMAL SIT IN A CRATE FOR AN EXTENDED PERIOD OF TIME.

THIS IS KIND OF OUR WORST NIGHTMARE TO GO TO THE FOURTH OF JULY HOLIDAY AND ALREADY BE THIS FULL BECAUSE WE DON'T HAVE ANY MORE KENNELS.

WE ARE AT 161% CAPACITY.

>> Reporter: THE HUMANE SOCIETY SAYS IF YOU FIND A STRAY DOG, THEIR BEST CHANCE TO BE REUNITED WITH THEIR OWNERS IS IF YOU HOLD ONTO THEM.

THEY RECOMMEND CHECKING FOR A PHONE NUMBER ON THEIR CALLER OR CHECK SOCIAL MEDIA FOR POSTS ABOUT LOSS DOGS.

IF ALL THAT FAILS, CALL THE NUMBER ON YOUR SCREEN, 858-726- 5678.

>>> AND OTHER HEALTHY JOBS REPORT WAS ANNOUNCED TODAY, BUT IN SOME OF THE FINER DETAILS THAT COULD BRING RELIEF TO INTEREST RATES IN THE MONTHS AHEAD.

THE FRIDAY BUSINESS REPORT.

>> VERY SOLID JOBS REPORT.

OVER 200,000 JOBS WERE CREATED AND THE ECONOMY IS IN LINE WITH EXPECTATIONS.

THE UNEMPLOYMENT RATE PICKED UP TO 4.1%.

WE HAVE HAD 40 MONTHS OF CONSECUTIVE JOB GROWTH, WHICH IS VERY STRONG FOR THE ECONOMY AS A WHOLE.

TWO HE STATISTICS THAT WERE INTERESTING IS THAT THE LABOR FORCE PARTICIPATION RATE INCREASED TO 62.6%, WHICH SHOWS THERE IS MORE PEOPLE ENTERING THE LABOR FORCE AND OF THOSE ENTERING, IT IS THAT 25 TO 54 PRIME AGE GROUP.

THAT LABOR RATE INCREASED TO 83.7%, WHICH IS THE HIGHEST IN 22 YEARS.

MORE PEOPLE ARE COMING INTO THE LABOR FORCE LOOKING FOR MORE OPPORTUNITIES OVERALL.

WAGES ARE INCREASING BUT THEY ARE INCREASING AT A DECREASING RATE.

IN FACT THIS REPORT WE SAW WAGES INCREASED 3.9% OVER A YEAR AGO, WHICH IS STILL MUCH HIGHER THAN THE CURRENT INFLATION RATE, BUT THIS IS THE FIRST TIME IN THREE YEARS THAT WE SAW THE WAGE GROWTH BELOW 4%.

>>> PRESIDENT BIDEN'S TEAM IS BEEFING UP HIS PUBLIC SCHEDULE AS HE TRIES TO SHIFT THE NARRATIVE AWAY FROM HIS POOR DEBATE PERFORMANCE AND CONVINCE DEMOCRATS TO CONTINUE TO SUPPORT HIS RE-ELECTION BID.

JULIA BENBROOK HAS THE LATEST.

>> Reporter: SPEAKING TO A CROWD IN WISCONSIN FRIDAY, PRESIDENT JOE BIDEN TRIED TO ASSURE VOTERS THAT HE IS READY TO LEAD FOR ANOTHER FOUR YEARS.

>> MY FRIENDS, I'M IN WISCONSIN FOR ONE REASON.

BECAUSE WE ARE GOING TO WIN WISCONSIN!

>> Reporter: AFTER A DISAPPOINTING DEBATE PERFORMANCE, HIS CAMPAIGN ANNOUNCED WHAT IT CALLS AN AGGRESSIVE TRAVEL SCHEDULE FOR THIS MONTH THAT WILL TAKE HIM, THE VICE PRESIDENT, THE FIRST LADY, AND THE SECOND GENTLEMAN TO EVERY BATTLEGROUND STATE.

THIS MOVE FOLLOWS CALLS FROM ALLIES TO RAMP UP CAMPAIGNING AND PUBLIC MESSAGING EFFORTS.

>> WE HAVE TO DO SOME THINGS TO REASSURE THE PUBLIC.

>> WHETHER IT IS A 60 MINUTES INTERVIEW OR SOMETHING AT THE PODIUM AT THE WHITE HOUSE OR THE TOWN HALL.

>> Reporter: BUT EVERY WORD WILL BE UNDER INTENSE SCRUTINY AS THE NUMBER OF ELECTED OFFICIALS, DEMOCRATIC DONORS, AND SUPPORTERS EXPRESS DEEP CONCERNS ABOUT BIDEN'S AGE AND CAPACITY TO SERVE A SECOND TERM.

>> EVERY TIME HE HAD A SLIP OF THE LIP -- WHICH WE ALL DO -- IT WAS ANALYZED AND MAY BE OVERANALYZED.

THAT IS WHAT HE CAN EXPECT BETWEEN NOW AND FOREVER.

>> Reporter: AFTER THE WISCONSIN RALLY, THE PRESIDENT SAT DOWN FOR HIS FIRST TELEVISED INTERVIEW SINCE THE DEBATES.

THE HIGH PROFILE ABC INTERVIEW WITH GEORGE STEPHANOPOULOS IS SET TO AIR IN ITS ENTIRETY FRIDAY EVENING AS A PRIME TIME SPECIAL.

REPORTING IN WASHINGTON, I AM JULIA BENBROOK.

>>> PSYCHEDELIC MUSHROOMS ARE ILLEGAL FEDERALLY BUT IN CALIFORNIA THEY ARE BEING SOLD IN PERSON AND ONLINE.

KPBS HEALTH REPORTER SAYS INTEREST IN MICRO DOSING PSYCHEDELICS FOR MENTAL HEALTH IS GROWING AND SO ARE CONCERNS OF POTENTIAL RISKS.

>> Reporter: SHE SAYS HER TRAUMAS BEGAN IN CHILDHOOD FROM FAMILY ISSUES, A DIFFICULT DIVORCE, A HIGH STRESS BIOTECH JOB, AND HEALTH CHALLENGES.

>> WHEN YOU HAVE A DEBILITATING PTSD AFFECTS FROM SO MANY TRAUMAS IN YOUR LIFE, YOU HAVE TO FIND A WAY TO BE YOUR OWN ADVOCATE.

I WANT TO BE THE BEST PERSON THAT I CAN TO BE WITH MY DOGGIES AND ENJOY MY LIFE.

>> Reporter: IN 2019 SHE SAYS SHE EXPERIENCED A SEIZURE AFTER TAKING HER ANTIDEPRESSANTS.

THAT IS WHEN SHE DECIDED TO SEEK ALTERNATIVE TREATMENT.

>> SO I BEGAN READING A LOT ABOUT CLINICAL TRIALS.

PSYCHEDELIC DRUGS, KETAMINE, LSD .

AND OF COURSE PSILOCYBIN.

>> Reporter: A STUDY BY UNIVERSITY OF CALIFORNIA SAID RESEARCHERS FOUND THAT MICRO DOSING RELATED GOOGLE SEARCHES IN THE U.S. HAVE SKYROCKETED IN THE PAST DECADE.

KEVIN YANG IS ONE OF THE RESEARCHERS.

HE SAYS PSYCHEDELICS HAVE ALSO GROWN IN POPULARITY AMONG CLINICAL RESEARCHERS.

>> IN MY OPINION FOR GOOD REASON THERE IS A CLINICAL TRIAL SO FAR SHOWING THAT IT IS USEFUL FOR TREATING THINGS LIKE DEPRESSION, PTSD, SUBSTANCE ABUSE DISORDERS.

>> Reporter: ABOUT HOW MANY PEOPLE ARE ACTUALLY MICRO DOSING.

BUT HE ADVISES CONSUMERS TO PROCEED WITH CAUTION.

>> WHAT IS HARD TO SAY WHETHER MICRO DOSING TRULY WORKS OR NOT .

SOME STUDIES HAVE SHOWN THAT IT DOES.

OTHERS HAVE SHOWN THAT IT DOESN'T.

THAT IS NOT TO SAY THERE ARE LOTS OF PEOPLE OUT THERE WHO ARE DOING IT AND CERTAINLY BENEFITING FROM IT.

>> Reporter: YANG SAYS TABLES CAN'T ALWAYS BE TRUSTED.

>> YOU CAN GO TO SMOKE SHOPS, CBD SHOPS, AND THEY WILL SELL THESE GUMMIES, CHOCOLATES THAT THEY ARE ADVERTISING AS MAGIC MUSHROOMS.

WHEN YOU LOOK MORE INTO THE INGREDIENTS OF WHAT IS ACTUALLY REALLY INTERESTING IS A LOT OF THESE THINGS THEY ARE SELLING ARE NOT ACTUALLY THE PSILOCYBIN MUSHROOMS THAT ARE BEING USED IN CLINICAL TRIALS.

THERE IS A MUSHROOM.

>> Reporter: AS OF MONDAY, SWEETS CONTAINING IT ARE BEING TIED TO NEARLY 50 ILLNESSES ACROSS TWO DOZEN STATES, ACCORDING TO THE FDA.

>> THERE IS NO RULES OR REGULATIONS ABOUT HOW THESE THINGS ARE PRODUCED, HOW IT IS BEING SOLD.

>> Reporter: SHE IS CAUTIOUS ABOUT HER PURCHASES AND SPOKE WITH A MICRO DOSING CONSULTANT WHO TAILORED A DOSING PLAN AND PROVIDED ONGOING SUPPORT.

>> IT BEGAN WORKING, LIKE, IMMEDIATELY.

I COULDN'T BELIEVE IT.

I WASN'T INTOXICATED.

I WASN'T IMPAIRED.

>> Reporter: SHE FOLLOWED THE PROTOCOL FOR ABOUT NINE MONTHS TAKING TWO PILLS OR GUMMIES A DAY.

SHE CREATED HER OWN RITUAL, LIGHTING CANDLES, DRINKING TEA, AND JOURNALING.

>> I'M NOT SAYING IT IS A MAGIC CURE.

IT JUST CURED EVERYTHING.

HAVING SOME OF THESE PROBLEMS FEEL A LITTLE BIT ALLEVIATED JUST MADE THE DAY EASIER TO COPE WITH.

>> Reporter: HEIDI DE MARCO.

KPBS NEWS.

>>> THE USE OF LITHIUM ION BATTERIES IS INCREASING EXPONENTIALLY.

THEY ARE FOUND IN EVERYTHING FROM CAR AND BIKE BATTERIES TO SMART PHONES.

THEY ARE AT RISK OF CATCHING FIRE OR EXPLODING DUE TO THE HEAT OF A FIRE.

BUT HOW DANGEROUS ARE THEY COMPARED TO OTHER OPTIONS?

KPBS TECH REPORTER THOMAS FUDGE IS HERE TO TALK ABOUT ALL THAT.

BACK IN MAY WE HAD A REAL SCARE WHEN THERE WAS THAT FIRE AT THAT MESA WAREHOUSE THAT STORED LITHIUM ION BATTERIES.

THAT WAS PRETTY SCARY.

>> IT WAS SCARY.

AND I TALKED TO SOME FIREFIGHTERS WHO WENT DOWN THERE AND WHILE THE FIRE WAS GOING AND THE FIRE STARTED ON MAY 15th, BY THE WAY -- WHEN THEY WERE DOWN THERE, THEY COULD ACTUALLY HEAR LITHIUM ION BATTERIES INSIDE EXPLODING.

SO WHAT THEY DID -- ONE THING YOU NEED TO KNOW ABOUT LITHIUM ION BATTERIES IS THAT THEY EMIT HYDROGEN, VERY FLAMMABLE GAS, WHEN THEY DO BURN.

SO THEY SENT ROBOTS INTO THAT SPACE -- THAT WAREHOUSE SPACE -- TO TEST THE ATMOSPHERE.

AND THEY DID FIND AN ATMOSPHERE THAT WAS VERY HEAVY WITH HYDROGEN.

IN FACT THEY HAD A VERY EXPLOSIVE ATMOSPHERE IN THAT BUILDING.

>> BUT YOU MIGHT THINK GIVEN ALL THAT THAT IT WOULD HAVE ENDED WITH A BANG, BUT IT DID NOT END WITH A BANG.

>> IT DID NOT END WITH A BANG, THANK GOD, BECAUSE YOU COULD HAVE HAD A BUILDING WIDE EXPLOSION THAT WOULD HAVE BEEN EXTREMELY DEVASTATING.

AND THAT DID NOT HAPPEN.

I PUT THE QUESTION OF WHY TO ROBERT, WHO IS A BATTALION CHIEF WITH THE SAN DIEGO FIRE DEPARTMENT AND ALSO AN EXPERT WHEN IT COMES TO LITHIUM ION BATTERIES.

AND WHEN THEY START TO BURN -- HE SAID IT IS DUE TO SEVERAL FACTORS.

ONE WAS HE SAID GOOD FIREFIGHTING.

THE OTHER WAS THE FACT THAT THIS WAREHOUSE WAS SO HUGE THAT YOU DIDN'T HAVE BATTERIES TOO CLOSE TO EACH OTHER AND SO YOU DID NOT HAVE THAT CHAIN REACTION THAT COULD HAVE LED TO A BUILDING WIDE EXPLOSION.

>> SO WHAT IS IT ABOUT LITHIUM- ION BATTERIES THAT MAKES THEM SUCH A HIGHER RISK?

>> WELL, LIKE I SAID, THEY EMIT HYDROGEN WHEN THEY BURN.

OF COURSE THAT CREATES A VERY SCARY SITUATION.

FIRE PRONE SITUATION IN THE AREA.

EVEN WHEN THEY ARE IN A NORMAL STATE, THEY ARE COMBUSTIBLE AND THEY CAN CATCH ON FIRE.

I SPOKE WITH A FELLOW NAMED KEN GRIFFITH, WHO IS A PROFESSOR OF CHEMISTRY AT UC SAN DIEGO WHO DEALS WITH THESE BATTERIES, AND HE WAS DESCRIBING THE WAY THEY WORK.

THEY ARE RECHARGEABLE BATTERIES AND THEY HAVE THESE IONS DIPPING IN BETWEEN TWO ELECTRODES INSIDE THE BATTERY.

THAT IS A DANGEROUS SITUATION JUST BY ITSELF.

AND IF THE BATTERIES ARE FLAWED, WHAT CAN HAPPEN IS YOU CAN HAVE A SHORT CIRCUIT.

AND HERE IS WHAT HE HAD TO SAY ABOUT THE DANGER OF A SHORT- CIRCUIT IN A BATTERY LIKE THIS.

>> ANYTHING YOU DO THAT CREATES A SHORT-CIRCUIT TO ALLOW ALL THAT HEAT TO BE RELEASED MEANS YOU ARE HEATING UP A LOT IN A VERY SMALL VOLUME AND SO THAT HAS THE POSSIBILITY TO TURN INTO A FIRE IF THERE IS A SOURCE OF FUEL AROUND.

>> JOHN, WHEN THE ELECTRIC FUNCTION INSIDE ONE OF THESE BATTERIES GOES AWRY, WHAT THEY CALL IT IS A THERMAL RUNAWAY.

AND I TALKED A LITTLE BIT WITH CHIEF -- THE SAN DIEGO FIRE DEPARTMENT -- ABOUT THAT AND HE SAID THAT CAN LEAD TO FIRES AND THAT CAN LEAD TO EXPLOSIONS.

ANYTHING THAT HEATS UP THAT BATTERY ENOUGH CAN MAKE IT EXPLODE.

HE GIVES THE EXAMPLE OF BEING WITH THE FIRE DEPARTMENT WHEN HE HAS HAD TO GO TO APARTMENT FIRES WHERE THERE IS AN ELECTRIC BIKE INSIDE WITH A LITHIUM-ION BATTERY.

>> MORE OFTEN THAN NOT WE ARE ARRIVING TO THE INCIDENT TO FIND THE WINDOWS ARE BLOWN OUT, THE DOORS ARE OFF THE HINGES, AND OF COURSE FOR US AND THE FIRE SERVICE, THAT MAKES IT EXTREMELY MORE COMPLICATED BECAUSE NOW WE HAVE A VENTILATED FIRE.

>> ANOTHER THING YOU NEED TO KNOW ABOUT THESE BATTERIES IS WHEN THEY ARE ON FIRE THEY ARE HARD TO PUT OUT.

YOU CANNOT JUST DROWN IT WITH WATER.

THAT DOESN'T WORK.

YOU CAN'T SMOTHER IT WITH A BLANKET.

SOMETIMES ALL FIREFIGHTERS CAN DO WHEN THESE BATTERIES ARE ON FIRE IS JUST WAIT FOR THEM TO USE UP THE FUEL AND WAIT FOR THEM TO GO OUT.

>> GOOD LORD.

LITHIUM-ION BATTERIES ARE NOT THE ONLY POWER SOURCE THAT IS A FIRE RISK, CORRECT?

>> NO, OF COURSE NOT.

THAT IS IMPORTANT BECAUSE YOU ALWAYS HAVE TO COMPARE THESE BATTERIES AND THEIR RISKS TO THE ALTERNATIVE.

LET'S GIVE THE EXAMPLE OF AN ELECTRIC CAR THAT USES NOT JUST ONE LITHIUM-ION BATTERY BUT A WHOLE BUNCH OF THEM -- A WHOLE BUNCH OF THESE CELLS IN THE CAR.

COMPARE THE FIRE RISK OF THAT CAR BATTERY TO AN INTERNAL COMBUSTION ENGINE.

ANYONE WHO THINKS AN INTERNAL COMBUSTION ENGINE IS NOT A FIRE RISK DOESN'T KNOW THAT MUCH ABOUT THEM.

AND HERE IS HOW PROFESSOR GRIFFITH AT UCSD MADE THAT COMPARISON.

>> WHAT IS ACTUALLY AMAZING IS IN SOME SENSE HOW SAFE LITHIUM- ION BATTERIES ARE.

WE PRODUCE BILLIONS OF THESE EVERY YEAR AND EVERY CAR HAS SOMEWHERE ON THE ORDER OF SEVERAL THOUSAND BATTERIES IN IT.

YET STILL WE HAVE VERY, VERY FEW FIRES IN THE CONTEXT OF ALL OF THAT.

>> JOHN, LIKE WE SAID BEFORE, WE ARE MAKING BILLIONS AND BILLIONS OF THESE BATTERY CELLS EVERY YEAR.

THEY ARE BEING USED IN MORE AND MORE PRODUCTS LIKE YOU SAID BEFORE.

ELECTRIC CARS, ELECTRIC BIKES, SMART PHONES, AND THEY ARE EVERYWHERE.

>> SO THAT FEATHERS INTO THIS NEXT QUESTION, HOW IMPORTANT ARE THESE LITHIUM-ION BATTERIES TO OUR EVER-CHANGING POWER SUPPLY?

>> ONE THING PROFESSOR GRIFFITH SAID TO ME IS, LOOK, YOU HAVE TO UNDERSTAND ONE THING.

THERE IS NO BATTERY THAT DOES A BETTER JOB OF STORING ENERGY THAN A LITHIUM-ION BATTERY.

SO THEY ARE SUPERIOR TECHNOLOGY IN A SENSE.

AND SO THEY ARE NOT GOING TO GO AWAY.

AS OUR POWER SUPPLY MOVES FROM FOSSIL FUELS TO ELECTRIC BATTERY POWER AND WE ARE DOING THIS FOR THE SAKE OF THE ENVIRONMENT BECAUSE IT IS CLEANER ENERGY, BUT AS THAT HAPPENS YOU CAN'T EXPECT THESE BATTERIES TO GO AWAY AND YOU CAN'T EXPECT THEIR FIRE RISK TO GO AWAY EITHER.

>> JUST DEAL WITH IT.

THOMAS FUDGE.

THANK YOU SO MUCH.

>> THANK YOU, JOHN.

>>> LOTS OF HEAT TO TALK ABOUT OVER THE COURSE OF THE NEXT SEVERAL DAYS.

THERE ARE EXCESSIVE HEAT WARNINGS OUT FOR THE INTERIOR VALLEYS AS WE WORK OUR WAY THROUGHOUT THE REMAINDER OF TODAY AND TO THE START OF THE WEEKEND.

AND THROUGHOUT THE DESERTS AS WE GO RIGHT INTO NEXT WEEK.

GOING TO BE VERY, VERY INTENSE HEAT, SO MAKE SURE YOU ARE STAYING WELL HYDRATED AND CHECKING ON THE PETS TO MAKE SURE THEY ARE HYDRATED.

FRIENDS AND FAMILY AS WELL.

TAKING BREAKS.

DIVIDING SOME SPOTS WITH SHADE.

OVERNIGHT LOW TEMPERATURES FOR TONIGHT WILL GIVE US A BREAK.

IT IS DRY AIR.

SO THAT IS EFFICIENT IN HEATING UP AND COOLING OFF DOWN TO 77 IN SPRINGS.

IT WILL QUICKLY TURN THE SWITCH ON THE HEAT HERE AS WE GO INTO TOMORROW.

APPROACHING 100 DEGREES.

OCEANSIDE TO CHULA VISTA, SOME IMMEDIATE COASTAL COMFORT AS WE HANG OUT AROUND 80 DEGREES.

LOOK AT THIS.

118.

WE WILL SEE THAT ON REPEAT AS WE GO RIGHT INTO NEXT WEEK.

MANY OF THESE SPOTS YOU SEE IN THE RED WILL ACHIEVE 110 IF NOT HIGHER EACH DAY OVER THE COURSE OF THE NEXT SEVERAL DAYS.

SO LET'S TAKE A LOOK AT THE NUMBERS HERE THROUGHOUT THE COASTAL ZONES.

NOTICE TUESDAY AND WEDNESDAY A LITTLE WARMER HERE.

WE CLIMBED BACK INTO THE MID- 80s.

OVERNIGHT LOWS INTO THE MID- 60s.

INTERIOR VALLEYS, ONE ROUND OF WARMTH AS WE WORK OUR WAY INTO THE WE CAN.

HEADING TOWARD TUESDAY AND WEDNESDAY ANOTHER ROUND OF EVEN MORE INTENSE HEAT AS WE CLIMB UP INTO THE MID-90s.

MEANWHILE FOR THE TERRAIN, HANGING OUT IN THE 80s.

SOME BREEZES TO CONTEND WITH HEADING TOWARD SUNDAY.

THE DESERTS, THOUGH, WILL BE TAKING THE BRUNT OF THE HEAT AS WE STAY INTO THE MID AND UPPER 100s AND PERHAPS EVEN 120 DEGREES HEADING INTO MONDAY.

FOR KPBS NEWS, I AM METEOROLOGIST JUSTIN POVICK.

>> IF YOU'RE LOOKING FOR THE BEST.

HARK TO TAKE YOUR FOUR-LEGGED FRIEND, LOOK NO FURTHER THAN MISSION BAY.

FIESTA ISLAND WAS NAMED BEST DOG PARK IN THE COUNTRY BY USA TODAY.

THE PUBLICATION SAYS NOMINEES WERE FIRST VETTED BY A PANEL OF EXPERTS, THEN THEY WERE PLACED INTO A POLL FOR READERS TO VOTE ON.

>>> OCEANSIDE HARBOR NOW HAS ITS FIRST FISHERMAN'S MARKET.

KPBS WITH COUNTY REPORTER TANIA THORNE SHOWS US THE POP- UP HAPPENING EVERY SUNDAY.

>> IT DOESN'T GET FRESHER THAN THAT.

EVERYTHING SOLD AT THIS MARKET IS PRODUCED BY THE BOATS THAT DOCK HERE AND THE LOCAL FISHERMEN.

TRAVIS.

I AM THE OWNER OF THE FISHERMAN'S MARKET OF NORTH COUNTY, AND WE ARE HERE EVERY SUNDAY, 8:00 A.M. TO 2:00 P.M.

HERE WE ARE IN OUR FIRST YEAR OF OPERATION.

OUR 10th SUNDAY IN OPERATION, AND THINGS ARE GOING GOOD AND WE'RE JUST TRYING TO GET THE WORD OUT.

IT IS REALLY PUTTING SOMETHING THERE FOR THE COMMERCIAL FISHERMEN THAT ARE LOCAL THAT DID NOT EXIST BEFORE AND IT'S REALLY BECOMING UTILITIES FOR THEM AND THE SURROUNDING COMMUNITY.

>> MY NAME IS PAUL.

MY BOAT IS IN ARIA B.

THAT IS OUR FISH COMPANY.

THE MARKETS IMPACTED OUR FISHERY BECAUSE IT ALLOWS US TO DIRECTLY SELL OUR FISH TO THE PUBLIC WHEREAS BEFORE WE WOULD SELL DIRECTLY TO WHOLESALERS.

THE WHOLESALER HAS TO OBVIOUSLY MAKE MONEY AND THEY BASICALLY SET THE PRICES FOR THE MARKET AND THE FISHERMEN ENDS UP MAKING LESS MONEY THAN THE WHOLESALER.

AND WE ARE THE ONES THAT GO OUT THERE AND CATCH THE FISH AND DO ALL THE HARD WORK.

WHAT THIS MARKET DOES IS GIVES US THE OPTION OF SELLING SOME OF OUR CATCH DIRECTLY TO THE PUBLIC, WHICH THE PUBLIC GETS TO PAY LESS FOR A FRESHER PRODUCT AND WE GET PAID MORE.

SO IT IS A WIN-WIN FOR THE PEOPLE THAT COME BUY FISH DIRECTLY FROM US AS WELL AS THE FISHERMAN.

THE FISH WAS CAUGHT IN THE LAST THREE DAYS.

THIS FISH WAS CAUGHT ON FRIDAY.

IT WAS SWIMMING IN THE OCEAN ON FRIDAY AND THIS IS SUNDAY MORNING AND IT'S GOING DIRECTLY TO PEOPLE'S HOUSES.

>> >> I LIKE HALIBUT.

>> I'M EASY-GOING.

I LOVE EVERYTHING.

SO IT IS HARD FOR ME TO PICK SOMETHING..

THIS IS THE SECOND TIME I HAVE GONE ROCK CRAB AND IT WAS DELICIOUS THE FIRST TIME.

WITH THE BENEFIT OF HAVING IT HERE, IT'S COMING RIGHT OFF THE BOAT.

SOMETIMES IT IS STILL FLOPPING AROUND, WHICH IS AWESOME FOR ME BECAUSE I WANT TO MAKE SURE IT IS SUPER, SUPER FRESH.

SO IT IS KIND OF NICE TO IN ESSENCE BREAK BREAD WITH EVERYBODY HERE AND GETTING SOME INSIGHT ABOUT WHAT IS THE CATCH OF THE WEEK AND KNOWING WHAT IS IN SEASON RIGHT NOW VERSUS WHAT'S NOT AND WHY WE MIGHT SEE MORE OF ONE THING AND NOT THE NEXT WEEK.

>> WE HOPE TO OFFER MORE.

WE HAVE OTHER FISHERMEN IN THIS HARBOR AS WELL THAT HAVEN'T HAD THE OPPORTUNITY TO GET THEIR OWN BOOTH YET BECAUSE WE HAVE BEEN SO SLOW.

THERE HASN'T BEEN ENOUGH DISBURSEMENT OF CATCH TO BE ABLE TO JUSTIFY HAVING MORE FISHERMEN WITH MORE FISH.

BECAUSE THE LAST THING WE WANT IS TO GO HOME WITH FISH.

>> NEXT WHAT WE WANT TO DO IS GIVE SOME DEMONSTRATIONS AS FAR AS HOW TO PREPARE THESE LOCAL SPECIES BECAUSE WE ARE GOING TO BE HERE EVERY SUNDAY FOR THE FORESEEABLE FUTURE, SO I WANT TO GIVE THEM MORE TECHNIQUES AND PREPARE THEM SO THEY FEEL A LITTLE MORE CONFIDENT IN MAKING THEIR PURCHASES.

>> I WILL TAKE 10 POUNDS OF ROCK CRAB, PLEASE.

YOU CAN FIND TONIGHT STORIES ON OUR WEBSITE, KPBS.ORG.

THANK YOU SO MUCH FOR JOINING US.

I AM JOHN CARROLL.

HAVE A GREAT EVENING AND A WONDERFUL WEEKEND.
