Hurricane Dorian spared South Florida from the worst of the winds, rain and storm surge. There were no mass evacuations. Power outages were few. But there was plenty of anxiety.

COMMENTARY

Here’s a dirty little secret about Amazon deforestation that liberals prefer you overlook: the slash-and-burn may be ugly under right-wing Brazilian President Jair Bolsonaro, but it was bad when leftists controlled the rainforest, too. Under former President Dilma Rousseff, the liberal darling who ruled Brazil from 2011 until her impeachment in 2016, Amazon deforestation actually increased.

In no way does that excuse Bolsonaro’s reckless efforts to accelerate the trend – which in 2019 have resulted in an alarming 85 percent rise in Amazon fires that have destroyed more than 7,000 square miles of rainforest. What it points out is that Brazil, left or right, is and largely has been a lousy steward of an emerald ecosystem known as the lungs of the earth.

Congressman Ted Deutch (D-FL) said on Sundial Monday that retreating from the Paris Climate Agreement makes America "weaker" and that he plans to push hard for two things in the coming months: a carbon fee and gun reform legislation.

If you live in Florida, you know the psychological toll hurricanes have on humans. We panic, we obsess over the latest weather report, we rant about horrendous evacuation traffic.

What’s far less known is the effect of hurricanes on non-human residents. One new study shows storms have a surprising evolutionary impact on spiders — producing a more aggressive population of arachnids.

APOLLO BEACH -- After two years and more than $4.5 million, scientists working with the Florida Aquarium have pulled off something no one else ever has: They coaxed imperiled Atlantic Ocean coral into spawning in a laboratory, aquarium officials announced Wednesday.

Fires in Brazil's Amazon rainforest are proliferating at an alarming rate.

That's the gist of an announcement this week by the country's National Institute for Space Research, or INPE. According to the agency, there have been 74,155 fires in Brazil so far this year — most of which erupted in the Amazon. That represents an astonishing leap of more than 80% over last year and by far the most that the agency has recorded since it began compiling this data in 2013.

If you want to know what climate change will look like, you need to know what Earth's climate looked like in the past — what air temperatures were like, for example, and what ocean currents and sea levels were doing. You need to know what polar ice caps and glaciers were up to and, crucially, how hot the oceans were.

James Valsaint is concerned about displacement in Little Haiti. He knows the neighborhood’s high elevation is attractive to developers and perspective homeowners because it doesn’t flood. He questions how the majority low-income residents in the area will fare as rent costs balloon and where they will go.

Damian McNamara is a homeowner in Morningside, less than a mile from Little Haiti. His neighborhood is affluent, as is the case with most coastal enclaves in South Florida.

Randall Dasher is a fourth-generation Florida farmer and until last year, he never had a crop of iron-clay cowpeas fail.

"Something has changed and somewhere, someway, that has affected our yields," he said Monday during a panel at the University of Florida, where farmers met with U.S. Rep. Kathy Castor of Tampa, scientists and agriculture officials.

Two dozen tiny leatherback turtles swam around in small tanks, attached by fishing lines to a system that kept them from hitting walls and hurting themselves. As an open-water species, leatherbacks don’t recognize barriers, so they are kept on leashes at Florida Atlantic University’s lab at Gumbo Limbo Nature Center in Boca Raton.

It was lunchtime and professor Jeannette Wyneken was feeding them a concoction she perfected over the years: organic gelatin, fish oil, protein and vitamins, shaped into little squares. Leatherbacks are picky eaters, feeding mostly on jellyfish.

As the planet heats up, polar ice melts, seas rise and Biblical-size rains become more frequent, hurricanes are expected to get wetter and more intense.

But less certain is how much climate change is making these fierce storms, which target Florida more than any other U.S. state, more punishing now.

Humans must drastically alter food production to prevent the most catastrophic effects of global warming, according to a new report from the United Nations panel on climate change.

The panel of scientists looked at the climate change effects of agriculture, deforestation and other land use, such as harvesting peat and managing grasslands and wetlands. Together, those activities generate about a third of human greenhouse gas emissions, including more than 40% of methane.

The Gulf Stream, the warm current that brings the east coast of Florida the mixed blessings of abundant swordfish, mild winters and stronger hurricanes, maybe weakening because of climate change.

Visible from the air as a ribbon of cobalt blue water a few miles off the coast, the Gulf Stream forms part of a clockwise system of currents that transports warm water from the tropics up the east coast and across the Atlantic to northwestern Europe. In the frigid climate near Greenland, the water cools, sinks and flows south again, rolling through the deep ocean toward the tropics.

In a time of climate change denial and vaccine resistance, scientists worry they are losing public trust. But it's just the opposite, a survey released Friday finds.

Public trust of scientists is growing. It's on a par with our trust of the military and far above trust of clergy, politicians and journalists.

The odds are stacked against Florida’s coral reefs.

A mysterious disease is devastating them. So is climate change, which warms and acidifies ocean waters. Development and pollution don’t help much, either.

Landmark federal legislation to help corals expired in 2000, and a new bill introduced Friday by Florida’s Republican senators would revive it.
