Pasadena is Getting Hotter, With Up to 18% of Days Hitting 90 Degrees or More

A new interactive tool in the New York Times website allows anyone living in Pasadena – and in any other place on Earth – to see how much warmer your hometown has grown over the last few decades.

The tool may have been published to emphasize the impact of climate change on temperatures worldwide, after the U.S. Environmental Protection Agency (EPA) recently removed its entry on the topic from the agency website. The EPA site’s U.S. and global Climate Change Indicators page was last updated in August 2016.

An article accompanying the New York Times tool says most people can expect to see more 90-plus degree days now compared to the year they were born.

If you were living in Pasadena 50 years ago, in 1968, for example, the City and surrounding areas were reasonably expecting at least 55 days per year to hit temperatures of about 90 degrees, according to the New York Times tool.

Today, the Pasadena area can expect 67 days at or above 90 degrees per year on the average, the tool would show.

In 1988, anyone living in Pasadena could reasonably expect about 58 days with 90-degree average highs. These days, that number has increased by 16 percent, according to the NY Times tool.

The Times article also said the Pasadena area could expect to see between 85 and 104 days of very hot days, or days with highs at an average of 90 degrees, by the end of the century.

The tool’s dataset stretches back to 1960 only, the authors noted. They added that Pasadena and areas around it are “likely to feel this extra heat even if countries take action to lower their emissions by the end of the century,” quoting an analysis conducted by Climate Impact Lab for the newspaper.

The Climate Impact Lab is a group of climate scientists, economists and data analysts from UC Berkeley, the University of Chicago, Rutgers University and the Rhodium Group.
