ATTACKS ON SCIENCE
*The White House Suppressed Science from Congressional Testimony*
White House officials stopped scientific information on climate change from being submitted in a written testimony to the House Intelligence Committee.
*******What's at Stake******
Global warming is already having significant and harmful effects on our communities, our health, and our climate. Sea level rise is accelerating. The number of large wildfires is growing. Dangerous heat waves are becoming more common. Extreme storm events are increasing in many areas. More severe droughts are occurring in others.
We must take immediate action to address global warming or these consequences will continue to intensify, grow ever more costly, and increasingly affect the entire planet—including you, your community, and your family.
The good news is that we have the practical solutions at hand to dramatically reduce our carbon emissions, slow the pace of global warming, and pass on a healthier, safer world to future generations.
With your help, we can accomplish it. Even in these difficult times for climate action, we can make a difference.
Together, we can tackle global warming.
SCIENCE
Global warming is happening now. The planet's temperature is rising. The trend is clear and unmistakable.
Every one of the past 40 years has been warmer than the 20th century average. 2016 was the hottest year on record. The 12 warmest years on record have all occurred since 1998.
Globally, the average surface temperature has increased more than one degree Fahrenheit since the late 1800s. Most of that increase has occurred over just the past three decades.
We are the cause. We are overloading our atmosphere with carbon dioxide, which traps heat and steadily drives up the planet’s temperature. Where does all this carbon come from? The fossil fuels we burn for energy—coal, natural gas, and oil—plus the loss of forests due to deforestation, especially in the tropics.
The scientific evidence is clear. Within the scientific community, there is no debate. An overwhelming majority of climate scientists agree that global warming is happening and that human activity is the primary cause.
