President Barack Obama has only five months left in office and he is doing everything he can to ensure he leaves behind a solid legacy when it comes to the hot issue of the environment and climate change. Only last week, he expanded a marine sanctuary off Hawaii to make it the largest in the world, and on Wednesday, he will deliver the keynote address at the annual Lake Tahoe Summit.

The 20th Annual Lake Tahoe Summit will take place in Nevada at the Lake Tahoe Outdoor Arena at Harveys, with the event scheduled to kick off at 1:30 p.m. PDT (4:30 p.m. EDT). The summit is a platform to review and discuss efforts to protect Lake Tahoe, a popular tourist destination on the California-Nevada border that is famed for its clarity.

According to his schedule on the White House website, Obama will arrive at the Reno-Tahoe International Airport at 3:30 p.m. EDT and will deliver his speech at 5 p.m. EDT.

Some of the issues affecting the lake are reduction in its clarity — largely as a result of rain runoff, warmer water temperature and invasive aquatic species.

Republican presidential nominee Donald Trump has challenged numerous executive actions concerning the environment and energy undertaken by Obama, threatening to roll them back. The Tahoe address will also offer Obama the chance to counter Trump’s rhetoric.

After his Lake Tahoe stop, Obama will head to Hawaii. A statement by the White House said: “On Wednesday evening, he will address leaders from the Pacific Island Conference of Leaders and the IUCN World Conservation Congress, which is being hosted in the United States for the first time. On Thursday, he will travel to Midway Atoll, located within the Papahānaumokuākea Marine National Monument” which he had expanded to 582,578 square miles on Aug. 26, making it the largest protected area on Earth.
