When you tack on warming of 5 – 6°F, that’s a noticeable difference. If humans are noticing it, so are plants, animals & ecosystems. Our home will be fundamentally different than they are now.
For many people, climate change still feels too abstract and faraway; This makes it more real. It’s eye-opening to see how much it will warm where you live. Armed with this information I’m very optimistic that we can confront and adapt to a changing climate.
L.A. is one of the first cities to get its act together, from the scientists all the way up to the Mayor. Nobody knew precisely how to adapt to climate change because no one had the data — until now. These are shocking numbers, and we have it in us as a city to adapt if we are to thrive.
What Does a Changing Climate Mean for the Communities of LA?
Until now, city planners, advisors, leaders and residents have been unable to properly estimate and prepare for anticipated changes. In response, researchers at UCLA down-scaled over 20 global climate models to better understand the local impacts of a changing climate.
Mid-Century Warming in the Los Angeles Region is the first study to provide regional climate change predictions for the greater Los Angeles area, with unique predictions down to the neighborhood level.

How Hot Will Your Neighborhood be in 30 years?
The Los Angeles Region is getting hotter. As the global climate changes,
communities like Hollywood, Woodland Hills, and Eagle Rock can expect
a dramatic increase in average temperatures.
Even with efforts to reduce greenhouse gas emissions, the Los Angeles region will be warmer by mid-century, with average annual temperatures rising 4-5 °F.
Coastal regions will warm more slowly than the surrounding deserts and mountains:
- Oceans and coastal cities are likely to warm 3-4°F
- Dense urban areas, including downtown LA, are likely to warm 4-4.5°F
- Mountains and deserts are likely to warm 4.5-5.5°F
The occurrence of “extreme heat days”, days when temperatures exceed 95°F, is expected to increase substantially:
- Coastal areas and central L.A. – the areas with the highest population – will see extreme heat days triple
- The San Fernando Valley, San Gabriel and desert areas will see extreme hot days double or triple
- Mountain areas will see extreme hot days increase by 5 to 6 times the current number.

The Climate Change in the Los Angeles Region Project
This study is the first in a series being conducted by atmospheric scientists at UCLA, employing an innovative technique for applying global climate models to the Los Angeles region to provide detailed projections of climate change. The second study in the series, Mid-and End-of-Century Snowfall in the Los Angeles Region, will be released in June 2013.
