The Disturbing Science of Global Warming

Scroll down to explore a learning path based on this topic.
Playlist Description

If you can't find relief from an intolerably cold winter during the insanely sweltering summer, it might be because you're experiencing the effects of global warming. Scientists believe the environmental pandemic is caused by a number of factors. The emission of greenhouse gasses into the atmosphere by ways of deforestation, pollution, carbon dioxide and more are said to play large roles in rising temperatures. When these gasses are released into the atmosphere, they create heat which becomes trapped and unable to naturally escape or dissipate. That's when things really start to heat up. Rashes of wildfires, mudslides, tsunamis and earthquakes fueled by global warming have devastated nations across the world in recent years. In fact, soon you may not have to go far for that beach vacation as sea levels have risen 8 inches since 1870.

But is global warming real? Why do some academic circles assert it's an undeniable fact, while others refute climate change altogether? Is it true that even if we were to significantly reduce carbon emissions and taking other precautions we couldn't fully reverse its effects? Learn the facts, and decide for yourself.

Parts of the United States have experienced an extremely cold and snowy winter, which is being referred to as the 'Polar Vortex' and 'Winter Storm Hercules.' Does this winter prove that global warming is fake? Trace explains climate change and why one extreme winter does not mean global warming isn't real.

Long examines an idea to fight climate change by spraying sulfuric aerosols into the atmosphere. Although cheap and effective, Long warns that the long-term side effects of such a large-scale geoengineering effort would be unknown. ----- This program was recorded at the 12th Annual Wonderfest, the San Francisco Bay Area Festival of Science. Wonderfest's broad goals are best described by its mission statement: Through public discourse about provocative scientific questions, Wonderfest aspires to stimulate curiosity, promote careful reasoning, challenge unexamined beliefs, and encourage life-long learning. Wonderfest achieves these ends by presenting series of scientific events to the general public. At most of these events, pairs of articulate and accomplished researchers discuss and debate compelling questions at the edge of scientific understanding. - Wonderfest 2010 Jane C.S. Long is the associate director for energy and environment at Lawrence Livermore National Laboratory.

Global warming is among the most alarming environmental issues that the world faces today. This phenomenon does not simply involve the significant rise in the earth's temperature but a lot more. The adverse effects of global warming have become more and more apparent since the dawn of the 20th century, with more hurricanes and tropical storms causing massive destruction in different areas around the world, more animal species losing their habitats and becoming extinct, and more people dying because of complications such as heat stroke. Here are 25 alarming global warming statistics. https://twitter.com/list25 https://www.facebook.com/list25 http://list25.com Check out the text version too! - http://list25.com/25-alarming-global-warming-statistics/ Here's a preview: By the end of the century, around 150,000 people will have died of heat related causes. The United States is responsible for 80 % of the total amount of fossil fuel consumed every year. Each year of the 21st century is among the hottest in history. The amount of carbon dioxide in the atmosphere has risen by 34 % since the 17th century. The temperature of the earth will soon become 5.8 degrees higher. Humans release 37 billion metric tons of carbon dioxide every year. The level of carbon dioxide in the 20th century has been the highest in 650,000 years. People dump carbon dioxide into the environment at 1000 tons per second. More than 1 million species have already faced extinction due to global warming. In the near future, around a hundred million people will see 3 feet of sea level rise. The Montana Glacier National Park now has about 30% of its total glaciers from 1910. The average temperature in three large countries has increased at two times the global average. There will be an increase of 7 to 23 inches in sea levels by the end of the century. The United States is the top global warming polluter in the world. By 2050, 15 to 37% of our plant and animal species could be wiped out. Over the past century, the sea level has risen by 10 to 20 cm. 400,000 square miles of Arctic Sea have already melted due to global warming. By 2030, the number of glaciers in the Glacier National Park will equate to zero. Global warming caused $100 billion worth of damage in the United States alone in 2005. The amount of carbon dioxide in the atmosphere has increased by 31 percent. The intensity and duration of deadly hurricanes have doubled since the last four decades. The rate of global warming has accelerated thrice faster over the past 30 years. The annual temperature of the world and the United States is now 1.0 F hotter compared to the temperature a century back. The past nine years have all been among the 25 hottest temperatures in history. Two of the world's hottest temperatures were recorded in the last ten years.

Understanding how global warming altered the lifecycles of plants and animals in the past can provide important insights about the impact of climate change in the future, says Stanford scientist Noah Diffenbaugh. His research team is using recorded observations of natural events to generate 30-year computer forecasts of how U.S. wine and corn production could be affected by global warming.

Global warming exists! But how do we know that? It may seem like a simple process of just looking at the temperature from year to year, but it is SO MUCH MORE than that! Our understanding of the global climate comes from a compendium of data including measured and tracked temperature, humidity, wind speed, and barometric pressure, spanning over 100 years of observation!! To study this massive amount of information and be able to surmise that the increasingly extreme and bizarre weather patterns are a result of human influence... it's truly an incredible accomplishment. So everyone who says during a blizzard "so much for global warming"... shut up. You're wrong.
