Something weird seems to be happening to our weather - it appears to be getting more extreme. In the past few years we have shivered through two record-breaking cold winters and parts of the country have experienced intense droughts and torrential floods. It is a pattern that appears to be playing out across the globe. Hurricane chasers are recording bigger storms and in Texas, record-breaking rain has been followed by record-breaking drought. Horizon follows the scientists who are trying to understand what's been happening to our weather and investigates if these extremes are a taste of what is to come.

Their beauty has captivated us for millennia. Their cost can be extraordinary–some are even considered priceless. Precious gems like diamonds, rubies, emeralds, opal, and jade are the ultimate treasures of the earth, and each one is made from a specific–and often torturous–recipe of chemistry, pressure, and heat. The secrets to their sparkle, color, and even strength lie deep inside the gems themselves, but could they also hold clues to one of the most enduring mysteries in the field of geology? From Tiffany’s workshop in New York to the sapphire mines of Sri Lanka, from North Carolina’s emerald fields to the jade-laden Forbidden City of China.

Coral reefs are not just beautiful, they are also home to over a quarter of all marine life and are crucial to human societies around the globe. But as the climate changes and oceanic heat waves become commonplace, corals are bleaching and reefs are dying off. Now, marine biologists from across the world are teaming up to counteract this catastrophe with a technique called assisted evolution. Follow scientists as they attempt to crossbreed heat-resistant corals, and even transplant corals’ algae, in a race to save the coral reefs from extinction
