HBO FILM-UNITED STATES — TOO HOT NOT TO HANDLE Global warming is the most urgent threat facing humanity today.  Heat waves. Melting glaciers. Rising sea levels. Catastrophic storms. Migrating viruses. Population displacement. Over the past 100 years, the mass consumption of fossil fuels, especially in America, has contributed to a dangerous warming of the earth that has adversely impacted the way we live. We are all contributors to global warming and we all need to be part of the solution. Segment Director OSCAR WINNER MARYANN DE LEO Executive Producer LAURIE DAVID Segment Producer VIBHA BAKSHI
