What is considered the most vulnerable part of the earth system an inconvenient truth?
Terms in this set (14) The oceans are considered the most vulnerable part of the earth system. The 'Greenhouse Effect' is a naturally occurring phenomenon. Radiation trapped in the earth's atmosphere serves to maintain a relatively constant and livable temperature.
What are three factors causing the collision between civilization and Earth?
What are the three factors mentioned that lead to a collision between civilization and Earth? In the film, Gore claims three factors are the cause of the collision between civilization and our planet, including technological revolution, the explosion of the population and humans' way of thinking.
What did Al Gore do for the environment?
As Vice President, Gore was involved in a number of initiatives related to the environment. He launched the GLOBE program on Earth Day 1994, an education and science activity that, according to Forbes, "made extensive use of the Internet to increase student awareness of their environment".
How does Al Gore highlight the effects of global warming?
Gore clearly shows the evidence that the increase in global temperature over the last 100 years is, to a large extent, due to greenhouse gas emissions from human activity. He then presents the three 'causes': population, technology and barriers to new thinking.
How does global warming occur?
Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.
Which takes up a large area of water on Earth?
The oceans are, by far, the largest reservoir of water on earth — over 96% of all of Earth's water exists in the oceans.
Why is studying ice cores important?
Ice cores have provided climate and ice dynamics information over many hundred thousand years in very high, sometimes seasonal, resolution. This information allows scientists to determine how and why climate changed in the past.
When did Al Gore first start talking about climate change?
In 1976, at 28, after joining the United States House of Representatives, Gore held the "first congressional hearings on the climate change, and co-sponsor(ed) hearings on toxic waste and global warming".
How does Gore expose the misconception that we have to choose between the economy and the environment?
Gore uses graphics, charts, and statistics to expose the myth that we have to choose between the economy and the environment. Gore exposes this choice as a false dilemma, claiming that doing the right thing inevitably moves us forward as a country.
When did Al Gore start on climate change?
1976 Gore has been involved with environmental work for a number of decades. In 1976, at 28, after joining the United States House of Representatives, Gore held the "first congressional hearings on the climate change, and co-sponsor(ed) hearings on toxic waste and global warming".
What did George W Bush do for the environment?
Fact Sheet: President Bush Has Advanced Cooperative Conservation And Protected The Environment. Instituted policies that helped reduce air pollution by 12 percent from 2001 to 2007 and adopted new policies that will produce even deeper reductions.
When did Al Gore start talking about climate change?
1976 In 1976, at 28, after joining the United States House of Representatives, Gore held the "first congressional hearings on the climate change, and co-sponsor(ed) hearings on toxic waste and global warming".
When did global warming start?
The instrumental temperature record shows the signal of rising temperatures emerged in the tropical ocean in about the 1950s. Today's study uses the extra information captured in the proxy record to trace the start of the warming back a full 120 years, to the 1830s.
What is carbon foot?
A carbon footprint is the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by our actions. The average carbon footprint for a person in the United States is 16 tons, one of the highest rates in the world. Globally, the average carbon footprint is closer to 4 tons.
What is evaporation condensation precipitation?
Evaporation: liquid surface water is heated by the sun and evaporates into atmospheric water vapor. Condensation: water vapor molecules come together and cool, forming liquid water. Precipitation: water returns from the atmosphere to the surface as rain, sleet, snow, hail, etc.
What is precipitation in hydrological cycle?
Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain.
What happens when volcanoes release greenhouse gases into the atmosphere?
The amounts put into the atmosphere from a large eruption doesn't change the global amounts of these gases very much. However, there have been times during Earth history when intense volcanism has significantly increased the amount of carbon dioxide in the atmosphere and caused global warming.
What are GHG emissions?
GHG emissions are often measured in carbon dioxide (CO2) equivalent. To convert emissions of a gas into CO2 equivalent, its emissions are multiplied by the gas's Global Warming Potential (GWP). The GWP takes into account the fact that many gases are more effective at warming Earth than CO2, per unit mass.
What was Al Gore known for?
Gore was the Democratic nominee for the 2000 presidential election, losing to George W. Bush in a very close race after a Florida recount. Albert Arnold Gore Jr. Washington, D.C., U.S.
How does Al Gore highlight the effect of global warming?
Gore clearly shows the evidence that the increase in global temperature over the last 100 years is, to a large extent, due to greenhouse gas emissions from human activity. He then presents the three 'causes': population, technology and barriers to new thinking.
Who told Leonardo DiCaprio about global warming?
President Al Gore In 1998, a 24-year-old DiCaprio went to the White House to meet the then US Vice President Al Gore, who is well-known for speaking out about the climate crisis. The aim of the meeting was specifically to discuss global warming, and DiCaprio cites the meeting as a landmark moment for his climate activism.

Did George W Bush believe in climate change?
Bush's do-nothing policy on global warming began almost as soon as he took office. By pursuing a carefully orchestrated policy of delay, the White House blocked even the most modest reforms and replaced them with token investments in futuristic solutions like hydrogen cars.

What are greenhouse gases TCS?
Greenhouse gases are gases in Earth's atmosphere that trap heat. They let sunlight pass through the atmosphere, but they prevent the heat that the sunlight brings from leaving the atmosphere.
