SCIENCE

The science clearly linking climate change to human activity has been confirmed repeatedly for over 50 years. To quote from NASA, “Multiple studies published in peer-reviewed scientific journals show that 97 percent or more of actively publishing climate scientists agree that climate-warming trends over the past century are extremely likely due to human activities.” 

During the same 50 years a fossil-fuel supported misinformation campaign has fought back, misleading the public and affecting the education of children and the legislation desperately needed. The IPCC (the United Nations) and the NCA (the US Federal Government) have issued report after report, often reporting that previous assessments had been too optimistic or that scientists had actually underestimated the pace and severity of the climate problem. 

Most of the leading scientific organizations throughout the world have issued public statements endorsing the position that climate change has been caused by human action.

In November, 2019, on the 40th anniversary of the world’s first climate conference, 11,000 scientists from 153 nations declared, in a Bioscience report, “clearly and unequivocally that planet Earth is facing a climate emergency and that we must change how we live.” The scientists say the urgent changes needed include ending population growth, leaving fossil fuels in the ground, halting forest destruction, and slashing meat eating.

As you explore the different sections in SCIENCE, you will find that climate change has created a web of interconnected relationships that are compounding the consequences we face. 

Setting records for the number of storms and wildfires, the contiguous USA ranked fifth warmest during 2020, according to a report issued by the NCEI, published on January 8, 2021.

Understanding Climate Change

JPL scientists study Earth’s changing climate, focusing on four broad themes: icy regions; the movement of water between sea, air, and land; greenhouse gas emissions and absorption; and our world’s ecosystems.
