In the Southern California of 2050, Angelenos could spend a quarter of the year sweating it out in temperatures of 90 degrees or more. The World Bank predicts as many as 140 million people could be displaced by 2050. Refugees leaving their homes for livable climates could lead to geopolitical instability. He agrees with the broad scientific consensus that if the trend continues - and physics says it will - sea level rise and droughts could render areas of the planet unsafe or even uninhabitable. For most of the globe, the warmest temperatures have come within the past 100 years. Data he examined from a wide variety of sources, including ice cores, tree rings and coral reefs, show that the warming trend began after the industrial revolution-the 1850s. The 20th century was Earth’s warmest period in nearly 2,000 years, he says. “If we don’t start now, we’ll be stuck in a very tough place in 2050.” As an expert in climate dynamics, Emile-Geay has devoted his career to understanding what’s coming for the planet. “The global climate is like an aircraft carrier turning it around is slow,” says Julien Emile-Geay, an associate professor of Earth sciences at the USC Dornsife College of Letters, Arts and Sciences.

The warming trend can feel overwhelming to understand, much less confront - especially with so many factors believed to affect how the planet is changing. The subtle signs we’re starting to see around us will be more pronounced, scientists say, and their impact will be easy to spot in everyday life. The water level has risen a little bit over the years, and the grandfather wonders how much land will still be above water when his grandson reaches his age.īy 2050, climate change and its reality will no longer be up for debate. A telltale bright red stain in the waves warns them of a toxic algal bloom. Meanwhile, on the coast, a boy and his grandfather walk along the beach, careful not to touch the water. He is heading to Oregon’s cooler climes to start again. It has become too hot to produce his Pinot Noir grapes anymore - all the nearby vineyards now grow wheat to fit the hotter weather. One hundred miles northwest, a third-generation vineyard owner finishes packing up his family and saying goodbye to the land.

As she hurries to get into an air-conditioned, self-driving car, she wonders if the temperature will finally dip below 90 degrees today - for the first time this November. The air is thick with smog, which aggravates her asthma. A young woman steps outside and puts on her air filtration mask. It’s 2050, and another balmy day in Los Angeles.
