A significant increase in health insurance premiums is affecting many Californians. One resident, Marc Silverman, 57, is now paying $800 a month for a minimal plan, double what he paid previously. His wife's premiums rose even higher, to $2,000 a month, after she was diagnosed with breast cancer and needed a better plan.

The increase in premiums is attributed to the expiration of federal subsidies, known as enhanced premium tax credits, which had provided financial aid to those purchasing insurance through the Affordable Care Act.

Further details on the impact of the expired subsidies are available from the source.
