Climate Change Predictions

$106 Billion

By 2050, up to $106 billion worth of coastal property will likely be below sea level (if we continue on the current path).

$12 billion Per Year

Over the next five to 25 years, greenhouse gas-driven temperature rises will likely necessitate the construction of new power generation that would cost ratepayers up to $12 billion per year.

12 Inches Higher

The U.S. coastline is projected to rise 10 to 12 inches in the next 30 years.*

Hotter and Hotter …

The year 2023, as of August, has broken multiple weather and climate records. Earth had its warmest July on record. The year-to-date (January to July) global surface temperature ranked as the third warmest such period on record. July also set a record for the highest monthly sea surface temperature anomaly (+1.78°F or +0.99°C) of any month in NOAA’s 174-year record.

According to the NOAA National Centers for Environmental Information’s Global Annual Temperature Outlook, it is almost certain (over 99 percent) that the year 2023 will rank among the five warmest years on record, with a nearly 50-percent probability that 2023 will rank warmest on record. It stands to reason that these increases will continue each year going forward.

Unprecedented Sea Level Rise

The projected 10 to 12 inches (on average) of sea level rise over the next 30 years (2020 to 2050) will be as much as the rise measured over the last 100 years (1920 to 2020).*

Emissions Matter

Current and future emissions matter. About two feet of sea level rise along the U.S. coastline is increasingly likely between 2020 and 2100 because of emissions to date. Failure to curb future emissions could cause an additional 1.5 to five feet of rise, for a total of 3.5 to seven feet by the end of this century.*

10% Crop Loss

Without adapting to the changing climate, some Midwestern and southern counties could see a decline in yields of more than 10% over the next five to 25 years, with a 1-in-20 chance of losses of crops by more than 20%.

$7.3 Billion More Per Year

Factoring in potential changes in hurricane activity, the likely increase in average annual losses is expected to grow by $7.3 billion, bringing the annual price tag for hurricanes and other coastal storms to $35 billion.

Trillions Below the Sea

There is a 1-in-20 chance—twice as likely as an American developing melanoma—that by the end of this century, more than $1 trillion worth of coastal property will be below mean sea level or at risk of it during high tide.

Higher Temperatures

If we continue on our current path, by the middle of this century, the average American will likely see 27 to 50 days over 90 degrees each year.
