Some folks with expert knowledge on climate and adaptation said it’s not all lost, yet, but the seas are certainly rising and the planet is getting warmer.
Anne Coglianese, the City of Jacksonville’s Chief Resiliency Officer, Esther Mullens, an assistant professor of geography at the University of Florida, St. Johns Riverkeeper Lisa Rinaman and State Climatologist David Zierden came together this week at Jacksonville University to give their perspectives on the competing themes of gloom and hope as they apply to the global climate crisis.
Are we doing too little too late, or past a tipping point?
Zierden reiterated what needed to be done in terms of reducing greenhouse gas emissions and dramatically reducing fossil fuel use.
“But, that’s far easier said than done,” Zierden said. “It would take a massive transformation of all systems globally in order to accomplish that.”
As to whether the world passed a tipping point, he couldn’t say, but suggested the path forward is doing as much as possible as quickly as possible.
“There’s been publications, especially on the West Antarctic Ice (Sheet), of a possible tipping point,” Zierden said. “But then, some of the goals we’ve seen in the Paris Accords and the (Intergovernmental Panel on Climate Change) report of limiting global warming to 1.5 degrees Celsius or 2 degrees Celsius are more arbitrary.”
These set numbers can reinforce a sense of doom among people, he added.
The IPCC report’s findings included the fact the planet warmed by 1.1 degrees Celsius over the baseline average temperature during the period 2011-2020. The baseline used is the average from 1850 to 1900. The world is likely to eclipse the 1.5-degree threshold within 10 years.
This all hits home in Florida in a number of ways, including development and insurance.
“Until very recent times, in spite of the known threat of sea-level rise, waterfront real estate and development was going on at paces unprecedented,” Zierden said.
The value of this real estate skyrocketed and the taxes on these properties became necessary to fund local climate adaptation projects, coincidentally.
“This is very out of my area — some smart people I know told me that, at some point, insurance is going to start driving this,” Zierden said, on the pace of continued coastal development.
When the land is generally at sea level, every inch of sea-level rise is an issue, which is the case around Northeast Florida.
“The most unique thing about the St. Johns River,” Rinaman said, “it’s one of the laziest rivers in the country, because it only drops in elevation 27 feet over that 310-mile journey, and so that makes it vulnerable to sea-level rise.
“In fact, the riverbottom of the St. Johns is below sea level for 150 miles inland. So, when we talk about sea-level rise, it’s not just a coastal issue. We’re seeing negative impacts of historic flooding all the way down to Lake George.”
The effects of more frequent, higher-intensity storms also have their impacts, like causing sewer systems to overflow.
In terms of what can be done, it’s easier to get adaptation projects passed and funded than those focused on prevention.
“There is a lot more political will out there for climate adaptation and for resilient solutions,” Coglianese said. “I think the main reason for that is it saves money. It saves cities money, it saves the federal government money to invest in solutions up front.”
She cited a study that noted every dollar spent investing in adaptation infrastructure before an event equals $6 when everything’s over. She also noted it doesn’t take a hurricane to put the hurt on a city like Jacksonville.
“It doesn’t need to be a major storm to really disrupt our city,” Coglianese said. “You could get three, back-to-back, small, very intense rainfalls in the span of a couple days that lead to really catastrophic impacts.”

Mike, great work. I applaud your efforts enormously because I presently make more than $36,000 each month from just one straightforward online company! You may vf-02 begin creating a steady online income with as little as $29,000, and these are only the most basic internet operations jobs.

(1) there is NO SUCH THING as an “EXPERT” on CLIMATE. Anyone who says they are an expert is therefore a liar.
(2) the SEAS are “NOT RISING.” THE LAND IS SINKING… A BIG DIFFERENCE.
(3) the PLANET is “NOT GETTING WARMER.” ie:
Back in the 1960’s and 1970’s, all of the climate “EXPERTS” proclaimed that were ON THE VERGE OF ANOTHER ICE AGE………
They were wrong.
Now the new, and some of the same old, “EXPERTS” proclaim we are in the midst of GLOBAL WARMING.
They are wrong again.
The Earth is 4.5 BILLION years old.
The continental plates move, the climate changes from ice age, to extreme warmth, and back again over the ages.
This is a NATURAL thing that HAS NOTHING TO DO WITH MANKIND.
(4) Everything that changes on EARTH does so because of THE SUN.

Please peddle your conspiracy theories somewhere else all those sites are bs.

We are definitely doing to little to late. How can a city that borders on a major river not be making changes due to climate change? We are going to be in trouble over the next decade and will spend a ton of money just to stay afloat literally.

You state that “DUE TO CLIMATE CHANGE… WE ARE GOING TO BE IN TROUBLE OVER THE NEXT DECADE.” ???????
And you accuse ME of peddling Conspiracy Theories.
What a flake.
In 2004, Al Gore said NYC would be underwater by 2013…?
I guess you are the NEW Al Gore.
ps: please learn English. in what you wrote above, TWICE you used the word “to” instead of “too.”
