Florida Must Establish an UPPER LIMIT on Sea Level Rise Before it’s Too Late.
The Problem:
•Florida’s people and economy face severe impacts from sea level rise.
• Flooding in coastal areas already disrupts transportation and causes property damage for thousands of businesses and homeowners.
• Coastal residents have begun to move inland to escape rising seas, flooding and stronger hurricanes.
• As sea level rise approaches critical upper limits, it endangers Florida’s economy, lives and livelihoods.
The Solution:
• Beyond two feet of sea level rise, parts of Florida will no longer be livable.
• State officials must make policies recognizing that beyond two feet of sea-level rise is too much.
• We must implement clean energy and transportation policies to cut the pollution driving these threats to keep Florida below these upper limits.
• As a leader, the state must then call on national and international leaders for emissions reduction.
The Strategy:
• Business leaders in Florida’s key industries understand that sea level rise, extreme heat and hurricanes jeopardize our economy, livelihoods and lives.
• Act now to protect businesses, employees and the bottom line from too much sea level rise.
• You can persuade policymakers to establish an upper limit to sea level rise.
• Join us and help ensure Florida’s future prosperity.
Upper Limit Project
We are a team of environmental strategists, non-profit leaders, climate scientists, and civic professionals who have galvanized around the unique idea that just like the UN Council of Parties set an upper limit to the amount of warming our planet can withstand with the Paris Climate Accord, the state of Florida needs to set an upper limit to the amount of sea level rise that it can withstand and still have a viable economy.
Our strategy is to identify key influencers with both public-facing and behind the scenes outreach campaigns to advance policies that will keep Florida at or below the upper limit.
The Upper Limit Project aims to shift the climate change conversation in Florida from one about adapting to sea level rise to one that prioritizes setting an UPPER LIMIT of two feet of sea level rise and prioritizing greenhouse gas reduction strategies to address the cause of the problem.
Florida’s state legislative leaders have finally acknowledged the need to address sea level rise, which is a significant and hard-won step toward preparing the state for climate change. Unfortunately, the state’s policies are largely focused on adaptation measures. They make little to no effort to reduce the greenhouse gas emissions that are the root cause.
Sea level rise will impact the pillars of the Florida economy, including agriculture, tourism, real estate, construction, ports, and international trade — all of which depend on proper management of natural resources. Making policy decisions now to maintain emissions below the upper limit will reduce future costs for transportation infrastructure, public health, disaster management, and social services. Limiting sea level rise and heat to the upper limit is essential to maintaining a functional Florida economy, and to the health, safety and well-being of Florida’s inhabitants.
Florida cannot adapt its way out of multiple meters of sea level rise — which is where we are headed if the globe continues to warm at its current pace and we lose the Greenland and Antarctica ice sheets. Besides property and infrastructure, over two feet of sea level rise threatens freshwater supplies, coastal tourism, and ecosystems including the Everglades – one of the most biodiverse places on Earth. Although the Florida Legislature directed considerable funding to adaptation to sea level rise, there are no policies to address the root cause of climate change.
To ensure Florida’s future economic prosperity, and the safety and well-being of its residents, its leaders must also embrace emissions reduction scenarios at the scale necessary to prevent Florida from being submerged.
The central goals of the Upper Limit Project are to move the State of Florida to formally recognize that there are upper limits of sea-level rise and heat beyond which Florida’s economic viability cannot be maintained and to establish policy that reduces greenhouse gas pollution, helping to keep Florida below those upper limits.
In addition, keeping Florida below the upper limit requires decarbonization at a global scale. So, the campaign must also advocate for the state to be a global leader and advocate for meaningful action at the national and international levels, to secure a global emissions pathway consistent with the ‘upper limit.’ Given that our economy is so significant, Florida is well positioned to wield influence.
In its research, the steering committee pulled together top climate scientists and experts to establish how much sea level rise and heat is “too much” for Florida and its residents to tolerate, based on an assessment of current climate science. Other experts worked with us to examine compounding impacts and the real world impacts that communities experience from rising seas, extreme heat and intensifying hurricanes. We have now finalized a simple emissions reductions scenario and policy pathway that will keep Florida within the defined ‘upper limit.’ By utilizing scientists and experts in the research phase, we also developed a network of experts who will continue to act as project advisors.
Two technical workshops asked experts to define the upper limit of sea level rise and heat based on existing data. In these workshops, we convened more than two dozen of Florida’s leading climate scientists, from major universities, posing the question: What is the upper limit of sea-level rise and heat that Florida can withstand?
We now have a simple, straightforward path for Florida to adopt, recognizing an upper limit to sea level rise and heat in order to keep Florida’s emissions in alignment with the upper limit.
The takeaways from these workshops can be found here (sea level rise) and here (heat), and represents a range of upper limit(s), provided in feet of sea level rise and key thresholds for heat.
We further defined the upper limit in a workshop using the framework of equity and real-world impacts. This convening included a subset of the technical experts from the previous workshops, as well as additional subject matter experts focused on topics such as housing, health, and other sectors that illustrate the cascading and compounding impacts of climate change. These experts looked at an emissions scenario that puts Florida at 2.75 feet of sea level rise, and 4-5 degrees Fahrenheit on average higher in 2050 than today. The experts looked at how life changes for Floridians under those conditions, (for example, what happens as a practical matter at 3 feet of sea level rise?) A synopsis of this workshop can be found here.
We then used existing frameworks to lay out a policy path of emissions reductions. The team worked with experts to connect sea level rise and heat projections, impacts, and emissions.
We now have a simple, straightforward path for Florida to adopt, recognizing an upper limit to sea level rise and heat in order to keep Florida’s emissions in alignment with the upper limit.
