Cities such as Amsterdam, Bangkok and Nairobi, Kenya, could experience major climate change impacts by 2050, according to a new study released earlier this week.

The study from Nestpick.com, an online platform for apartment rentals, shares data on how temperature changes, water shortages and rising sea levels will impact 85 global cities over the next three decades, according to a news release. The cities were chosen based on their inclusion in top tourist destinations lists for Generation Z and millennials.

The total scores for each city were determined by adding the scores from potential sea level rise impact, climate shift and water stress increase. The sums were then converted proportionally so that all scores are out of 100, according to Nestpick researchers.

Nestpick found that Bangkok might experience the greatest climate change by 2050, with a temperature increase of just more than 3 degrees Fahrenheit. The capital of Thailand also had the highest risk of flooding among cities surveyed. Nairobi might see a temperature increase of more than 4 degrees and an overall shift in climate type.

In Melbourne, Australia, the demand for water might be double the supply by 2040, according to Nestpick. Ho Chi Minh City, Vietnam, and Amsterdam ranked second and third, respectively, on the total scores list.

United States cities saw mixed results in the survey, released Wednesday. Orlando, Florida, and Las Vegas each ranked near the bottom of the total score list, indicating that they are less likely to see climate change impacts by 2050. Boston, on the other hand, ranked in the top 10 for both total score and climate shift score.

Two of the nation's cities, Baltimore (6.03 degrees) and Cincinnati (6.08 degrees), ranked in the top three for greatest potential temperature shift by 2050. Ljubljana, Slovenia, had the highest overall potential temperature shift at 6.35 degrees.

"Cities are at the forefront of the climate crisis: over 70% of cities are dealing with the effects of climate change, and yet 75% of global carbon emissions are caused by cities," said Ömer Kücükdere, founder and CEO of Nestpick.com, in a written statement. "Given how connected they are with their constituents, local officials, more than any other authority, are in the best position to set the agenda on climate change."

But a separate global study of 66 cities released Thursday indicates that few – only one-fifth of those surveyed – have extensive clean energy initiatives in their resilience plans.

The survey from the American Council for an Energy-Efficient Economy, a nonprofit that advances energy policies, rated the "extent and quality" of clean energy initiatives obtained from the now-shuttered 100 Resilient Cities network. Only 20% received "exemplary" or "substantial" ratings, and less than half received "adequate ratings" for renewable energy.

Four cities – Athens, Greece; Buenos Aires, Argentina; Honolulu; and New York City – received "exemplary" ratings for energy efficiency from the council.
