Meteorological spring begins a week from Sunday, but spring-like temperatures are already in place across the Florida peninsula, with some 90-plus readings in inland parts of South Florida.

In Broward County, Weston hit 90 and an observer near the Fort Lauderdale Executive Airport reported a high of 92.

In the Keys, Key West tied a 93-year-old high temperature record Monday with 84. And in Central Florida, Leesburg tied a record warm minimum temperature with 65.

Toasty temps are set to continue until Friday, when a cold front knocks temperatures back into the 60s and 70s for the weekend. until then, expect more record warm temperatures.

“Naples will have to be watched as the records there are mid to upper 80s and we will certainly be in that ballpark,” the National Weather Service said in its Tuesday discussion from Miami.


FINANCIAL STORM WARNING: There are plenty of pins that have the potential to pop the economic bubble that has been pumped up by artificially low interest rates set by world banks over the last 10 years. One of them is the spread of the coronavirus, which is already doing damage to the Asian economies.

Here’s another one: extreme weather.

A paper published Monday by experts at the University of California at Davis argues that there’s too much unpriced risk in the energy market due to weather-related events, especially excessively high temperatures.

“Unpriced risk was the main cause of the Great Recession in 2007-2008,” said author Paul Griffin, an accounting professor at the UC Davis Graduate School of Management. “Right now, energy companies shoulder much of that risk. The market needs to better assess risk, and factor a risk of extreme weather into securities prices.”

Excessive heat has the ability to impact agriculture, interfere with delivery of energy and water, and disrupt transportation.

“Despite these obvious risks, investors and asset managers have been conspicuously slow to connect physical climate risk to company market valuations,” Griffin said in the paper published by the academic journal, Nature Energy. “Loss of property is what grabs all the headlines, but how are businesses coping? Threats to businesses could disrupt the entire economic system.”

He added: “While proprietary climate risk models my help some firms and organizations better understand future conditions attributable to climate change, extreme weather risk is still highly problematic from a risk estimation standpoint,” he concluded in the article.

“This is because with climate change, the patterns of the past are no guide to the future, whether it be one year, five years or 20 years out. Investors may also normalize extreme weather impacts over time, discounting their future importance.”

Climate change shocker: Third of all species could be extinct by 2070

Most people consider sea level rise the biggest problem related to climate change, and that is a critical issue, especially if you live in coastal areas and states like Florida. But here’s another dire consequence: a third of all plants and animal species could be extinct in the next 50 years.

Researchers at the University of Arizona looked at localized plant and animal extinctions in the past that have occurred in specific areas. They found that up to 50 percent of species suffered local extinctions if maximum temperatures increased by more than 0.5 degrees Celsius and 95 percent if they increased by more than 2.9 degrees.

As a result, the rate of extinction is highly dependent on how much warming occurs in the coming years, according to the researchers, Cristian Román-Palacios and John Wiens, of the Department of Ecology and Evolutionary Biology at the University of Arizona.

“In a way, it’s a ‘choose your own adventure,'” said Wiens. “If we stick to the Paris Agreement to combat climate change, we may lose fewer than two out of every 10 plant and animal species on Earth by 2070. But if humans cause larger temperature increases, we could lose more than a third or even half of all animal and plant species, based on our results.”

As one example, they considered the Alligator Juniper tree in Arizona. In flat lands, the plants are dying due to rising daytime temperatures. “Repeated surveys have shown that this species is literally being pushed up the mountain slopes under the impact of climate change,” the university said in a news release.

Here’s the kicker: Extinctions are projected to be two to four times more common in the tropics than in temperate regions. “This is a big problem, because the majority of plant and animal species occur in the tropics,” Román-Palacios said.

Both plant and animal species will be equally affected, the researchers said.


SPRING IN THE AIR: Clear skies with plenty of sunshine will give temperatures a boost through at least Thursday of this week, with highs rising into the low 80s on the East Coast and as high as the upper 80s in southwestern parts of the Florida peninsula, according to the National Weather Service.

Beyond that, NOAA’s Climate Prediction Center is calling for below normal temperatures in all of Florida from next Saturday into the following week.

NOAA will release its full March forecast on Thursday. The latest long-range CFS model shows cooler weather hanging on the first week of March followed by above normal temperatures as we head into the second half of the month.

RECORD WATCH: Vero Beach posted a record warm low Sunday of 71 degrees. It beat the old record of 70 set in 1965.

Nice week on tap for Florida peninsula; January was record warm worldwide;

With strong easterly winds and a cold front stalled out over the Keys, some decent rainfall totals were occurring over southeastern Florida and the Keys. A CoCoRaHS observer for the national precipitation network reported 1.54 inches in Key Largo from Saturday through early Sunday morning.

An observer in North Miami Beach reported 1.24 inches; and an observer in Fort Lauderdale reported 1.45 inches.

Palm Beach County reported around a quarter of an inch. Lighter amounts fell along the Treasure Coast.

Another nice warm-up is scheduled for the coming work week, but then a cold front knocks temperatures back to below normal next weekend, just in time for the start of the exhibition baseball season.

The Climate Prediction Center is calling for February to go out on a slightly cooler note, especially the southern tier of states from New Mexico all the way to the Carolinas and the Mid-Atlantic States on the East Coast.

ANOTHER JANUARY, ANOTHER RECORD: Earth had its warmest January in the 141-year-old record, the National Center for Environmental Information (NCEI) said on Thursday.

Temperatures worldwide were 2.05 degrees Fahrenheit above the 20th century average, which beat the previous record for the warmest January by 0.04 of a degree. That occurred in January 2016.

“The four warmest Januaries on record have occurred since 2016, while the 10 warmest Januaries have occurred since 2002,” NCEI, a NOAA agency, reported. “The only Januaries with a global land and ocean surface temperature departure from average above 1.0°C (1.8°F) occurred in 2016 and 2019.”

The contiguous U.S. had its fifth warmest January, with records in that category going back 126 years. Hawaii had its second warmest January but Alaska had its coldest January since 2012. In fact, it tied 1970 as the 13th coldest January on record.

Every state in the Lower 48 had above normal temperatures, including Florida, which was above average but not record warm. Highest temperature anomalies were found in Texas and Oklahoma, the Great Lakes States, and the Northeast.

The Caribbean had its second warmest January, also behind 2016.

So I figured it was a good time to take a peek at sea surface temperatures in the Caribbean and the Main Development Region of the tropical Atlantic. It’s early, of course, but very warm water temperatures seem to be setting up shop from the coast of Africa all the way west into the Caribbean and Gulf of Mexico.

Particularly high temperature anomalies are in place off the U.S. East Coast, with the highest being in the Mid-Atlantic.

‘Climate chaos’ cited in stinging report on declining bee populations

MORE CLIMATE CHANGE BUZZ: A rapidly warming world has bumblebees on a fast track to extinction, a new study says. That’s a big problem because bumblebees are the world’s best pollinators.

“We have now entered the world’s sixth mass extinction event, the biggest and most rapid global biodiversity crisis since a meteor ended the age of the dinosaurs,” says Peter Soroye, a PhD student in the Department of Biology at the University of Ottawa in Canada.

Soroye and colleagues developed a new type of climate analysis that takes into account how different species tolerate temperature change, drought and heatwaves. They then applied this technique to 66 bumble bee species across North America and Europe, collected over a 115-year period from 1900-2015.

Using this new “climate chaos” technique, the researchers showed how bumblebee populations have changed by comparing where bees are now to where they were historically.

“We found that populations were disappearing in areas where the temperatures had gotten hotter,” Soroye says. “Using our new measurement of climate change, we were able to predict changes both for individual species and for whole communities of bumble bees with a surprisingly high accuracy.”

They said the bees are disappearing at rates “consistent with a mass extinction.”

“If declines continue at this pace, many of these species could vanish forever within a few decades,” Soroye said.

Bumblebees, although they do not produce honey, are the most effective pollinators for tomatoes, squash and berries, so the loss would be significant.


GET OUT THE BEACH CHAIRS: The announcement last week that Earth had its warmest January on record was followed up with another milestone: Antarctica recorded its warmest temperature ever, a balmy 65 degrees at Esperanza Base along Antarctica’s Trinity Peninsula.

That busted the previous record high of 63.5 degrees set in 2015.

The peninsula is heating up quicker than most other places on the planet.

“In just the past 50 years, temperatures have surged a staggering 5 degrees in response to Earth’s swiftly warming climate,” the Capital Weather Gang at The Washington Post reported Friday.

“Around 87 percent of glaciers along the peninsula’s west coast have retreated in that time, the majority doing so at an accelerated pace since 2008.”

Sea level rise expected to displace 13 million, new study says

NEWS FLASH: The National Weather Service kicks off Severe Weather Awareness Week in Florida with a look at lightning — appropriately, since Florida is the lightning capital of North America and one of the most lightning prone areas on the planet. Florida has an average of 1.2 million cloud-to-ground lightning strikes per year. “Most people struck by lightning are not killed, but suffer significant injuries,” according to NOAA. “On average, lightning kills 27 people each year in the United States and injures another 243. Florida averages 7 fatalities per year due to lightning and often leads the nation in lightning deaths.” There were three fatalities in Florida last year. (Image credit: NOAA)


OR YOU COULD LIVE ON A BOAT: How do Atlanta, Dallas, Denver and Las Vegas sound as places to live if you’re fleeing rising sea levels? A new study by the University of South Carolina looks at the probable impact of sea level rise and the redistribution of population that could result.

Researchers estimate 13 million coastal residents in the U.S. will need to move by 2100. Landlocked cities, especially those mentioned above, would get the brunt of the refugees, and the relocations will trigger battles for jobs, high-priced housing and other resources.

“By the end of the century, 6 feet of ocean-level rise would redraw the coastline of southern Florida, parts of North Carolina and Virginia and most of Boston and New Orleans,” according to a news release by USC’s Viterbi School of Engineering.

Researchers used artificial intelligence, which analyzed migration patterns after Hurricane Katrina and Hurricane Rita, to make their conclusions. They anticipate a 6-foot sea level rise.

“When migration occurs naturally, it is a great engine for economic activity and growth,” said co-author Juan Moreno Cruz, an economist and professor at the University of Waterloo in Ontario, Canada, who also participated in the project.

“But when migration is forced upon people, productivity falls and human and social capital are lost as communities are broken apart. Understanding these migration decisions helps economies and policy makers prepare for what is to come and do as much as possible to make the influx of migration a positive experience that generates positive outcomes.”


ECFL rainfall

ENOUGH TO WET YOUR WINDSHIELD: An early week cold front could drop a few hundredths of an inch of rain in East-Central Florida and South Florida, but nothing too dramatic. Stronger storms could dampen the upcoming weekend, forecasters said. (Image credits: NWS-Melbourne, above; NWS-Miami, below)

One of the challenges of living in Florida is dealing with its yo-yo temperatures during the winter. For example, most of the peninsula is forecast to be in the 80s today — with mid-80s over the interior all the way up into the Orlando area — but then plunge with Sunday’s cold front.

In Orlando today’s forecast high is 85, and Sunday morning’s forecast low is 47; Monday morning’s is 43. That’s a 40-degree temperature drop and any way you slice it or dice it, it takes some adjustment.

Put the thermostat on AC one day; flip it over to heat the next.

Fortunately, once this initial cold snap is over early next week it looks like we’ll be settling into a little longer pattern of temperatures that are close to average for this time of the year, according to the National Weather Service.

Friday’s run of the GFS forecast model suggests another period of much-above normal temperatures toward the middle of the month.

Normal highs in Miami edged down to their lowest of the year on Tuesday, from 77 to 76. That’s the normal high until January 23, when they begin the long march back up into the 80s and beyond. It’s a similar story around the state — the normal high in West Palm Beach bottoms out at 74 on Sunday, January 6 and begins bouncing back on January 18.

Orlando’s normal high is 71 and remains there until January 24, when it edges up to 72.

Tampa’s normal high of 70 begins climbing on January 28, when it’s 71.

HURRICANE RESEARCH: Climate change was responsible for the epic amount of rainfall generated by Hurricane Florence, the 2018 storm that swamped parts of North Carolina with more than 35 inches of rain, a new study by Sony Brook University in New York concludes.

Prior to Florence’s landfall in September, a university research team projected that rainfall amounts would be up to 50 percent higher due to warmer water temperatures.

“Rainfall amounts over large ranges were significantly increased,” the university said in a news release Thursday. The size of the storm also expanded.

“This post-storm modeling around climate change illustrates that the impact of climate change on storms is here now and is not something only projected for our future,” said Kevin Reed, assistant professor in the School of Marine and Atmospheric Sciences at Stony Brook.

Reed explained the storm modeling techniques his team used in this YouTube video.

The research was published in Science Advances.

2019 wrap, decade wrap, and what Mark Twain (reportedly) said …

WEEKEND COLD FRONT UPDATE: Three days out, Sunday morning forecast temperatures are on track to be the coolest since early December, as per the National Weather Service.

This is the time of the year to keep a look out for those Polar Express fronts that leave tourists grumbling and locals searching the far reaches of their back closet to find warmer sweaters or jackets. It doesn’t look like anything too radical at this point, and some people do like a chilly day or two.

But NWS forecasters in Miami posted this caveat: “Sunday afternoon, values could struggle to reach 70. Those with agricultural interests may want to keep a close eye on the forecast as trends could change.”

In any event, temps should bounce back relatively quickly, and the new January forecast from NOAA’s Climate Prediction Center, released Tuesday, calls for overall above normal temperatures in Florida.


DECEMBER WRAP: The month goes into the books wet and warm across most of the peninsula, as well as the Keys and North Florida. Miami crossed the finish line with temperatures 3 degrees above normal — there were 22 days with highs in the 80s and the high only failed to reach 70 once, on December 3 (68). Precipitation was 4.39 inches above average.

Key West was 3.9 degrees above average and finished December with a 5.49-inch rainfall surplus.

Orlando was 4.9 degrees above average with a rainfall surplus of 2.37 inches.

Tampa was 4.5 degrees above normal with precipitation 2.02 inches on the plus side.

Jacksonville topped out 5.4 degrees above normal with a 2.06-inch rainfall surplus.

Tallahassee was an exception to the precipitation trend in Florida — it was a bone-dry fall with the exception of October — by turning in a rainfall shortfall of 0.44 of an inch. Temperatures were still 4.6 degrees above normal, however.


2019 WRAP: In Miami, every month of the year ended with above normal temperatures with the exception of January, which were down 0.2 of a degree.

In Orlando, every single month of 2019 had temperatures above the 30-year average, and February was wildly out of whack, with temps 7.1 degrees above normal.

Ditto for Tampa, except November temperatures came in dead-on normal.


DECADE WRAP: Floridians spent some of the 2010s dodging catastrophe, managing to side-step the brunt of hurricanes Sandy (2012), Matthew (2016), and Dorian (2019). The Keys weren’t as lucky with Irma (2017) and the panhandle was clobbered by Michael (2018).


DECADE LOOK-AHEAD: Lots of people want to compare the new decade to The Roaring Twenties of the last century. It has a catchy ring to it and portends excitement. But history doesn’t repeat, it only rhymes, according to Mark Twain.

Besides, the 1920s had some horrific hurricanes, including the 1926 Miami Hurricane, the 1928 hurricane that killed thousands in the Glades, and the last major hurricane to slam Tampa in 1921 (also known as the 1921 Tarpon Springs Hurricane).

I have a feeling that the big story of the new decade in Florida will be accelerating climate change and the accompanying sea level rise that’s already forcing government officials to make tough decisions in the Keys.

Of course, as always, expected the unexpected.
