Billionaire investor Warren Buffett’s company Berkshire Hathaway faces a number of votes related to climate change this weekend as part of its annual shareholders’ meeting on Saturday.

This is the second year in a row that climate change has made its presence known at the meeting. Last year, the meeting was dominated by controversy when a Nebraska anti-war group with shares in the company pushed for a vote on a resolution to do a study on how climate change affects the company’s insurance business.
