What Rising Seas Institute Inc does
Mission
To provide intellectual and practical leadership for the challenge of adapting to rising sea levels and serve as a resource and global reference center for the public, diverse professions, government agencies, academia, and communities.
As stated on its FY2024 Form 990.
Programs
Educational Expeditions - We organize Fact Finding Expeditions to glaciers and ice sheets which are the ultimate source of rising sea level so that leaders understand the magnitude, potential abruptness, and unstoppable aspects of rising sea level, particularly Greenland and Antarctica. We also serve as expert lecturers on other select trips. These are high level discussions with scientists, military leaders, and leaders from across society who can help assess and prepare for change in the public interest.
$155,747 spent$86,070 earned by the program73% of program spendingPuerto Rico Program - Starting in mid-2021, the Rising Seas Institute has partnered with the Puerto Rico Science Technology and Research Trust, a 501c3 to create a program, the Caribbean Center for Rising Seas, effectively as a joint venture. The goal is to help Puerto Rico and the Caribbean adapt and thrive in the new era of increasing flood risk from storms, tides, and sea level rise. The program will establish Puerto Rico's leadership as a center of excellence and innovation, serving as a model on how to prepare for the challenges ahead.
$44,094 spent$78,000 earned by the program21% of program spendingPublic Lectures and media interviews - The Founders of the Rising Seas Institute, John Englander and Robert W. Corell, have given more than a hundred presentations and interviews over the last decade explaining the science of rising sea level and the need to plan better for adaptation. The New York Times published a major article about climate change by Bret Stephens on October 30th, 2022, and credited the work of the Rising Seas Institute. Other media interviews have included The Discovery Channel, NPR, Fox Business Channel, and China TV, as examples. One particular lecture in London at the prestigious Royal Institution in February 2019, "Sea level rise can no longer be stopped; what next?" has been watched on YouTube by well over three hundred and sixty thousand people globally.

The organization over time
Each line starts at 100 in 2020, so what you read is the shape rather than the size: 150 means half as much again as 2020, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2023 to 2024, from $209k to $0 (−100%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 5 reported years ran a deficit.

The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
Who funds it, year by year
2019 → 2023: the base broadened from 1 funder to 2 funders, grant income fell $20k → $17k.
3 of 7 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 17% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $42k arriving through sponsors registered in 3 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
