If you look up Global Warming or Climate Change on Youtube you will find an array of videos. Here are some of the best that I have found.
4:00 Glaciers in the Alps are retreating twice as fast compared to the rate 150 years ago.
5:00 Greenhouse gasses–water vapour, carbon dioxide, methane have kept Earth's temperature stable for millions of years until recently.
6:10 60% of carbon emissions come from electricity generation and transportation.
6:50 In 1750 CO2 in atmosphere was 280 parts per million to 370 ppm today.
9:25 We could reach 9.3 billion people by 2050
11:20 Big cities run 3-5 degrees warmer than their surroundings, increasing mortality due to heat waves.
15:00 Rising temperatures are also increasing the range of diseases, vectors like mosquito, also stronger hay fever season.
21:00 El Nino of 1983–5 months of continuous rain and tidal flooding. In 3 months it rained as much as it did in 25 years.
24:00 The infrastructure prep required to prepare for climate change is neither simple nor small and they need to start now.
26:00 Centuries old plantation fields and ranches are starting to dry out and suffer diminishing yield as watershed ecosystems are disrupted.
30:00 1 degree Celsius warming will reduce rainfall by 10%. Imagine 10% less world food supply. In 100 years we need 60% more food to cover population growth with less arable land. Food security is going to be of major concern for nations.
34:00 Disruption in the Gulf Stream because of reduced salinity from Greenland, Arctic and Glacial melts could cause sudden and catastrophic climate or weather shifts.
40:00 Technology already available to make a difference in significantly reducing pollution and CO2 emissions. Each day the sun sends enough energy to power life for all of us for 27 years! Solar energy creates 4 time more jobs per kilowatt hour of electricity generated compared to fossil fuel generated power.
National Geographic–Earth Under Water, solutions for saving major coastal cities. New York, London, San Francisco and others. The tech is already available to protect some cities not all. Miami, Bangladesh let alone small island nations may not see through 2200 unless we start to make major strides in affecting green house gas levels.

The Effect of Global Warming on Earth up to 6 degrees Celsius. Presently we are up 0.8 deg Celsius
Anthropocene–This video provides very good data on Global Warming and Sea Level Rise.
