Our Climate

If it is still available please go to NASA’s Global Climate Change page here to look at the evidence for climate change.

We also outline the information here with all the appropriate references. You can also hear Exocaster Hannah talk about the facts in our January 2017 podcast.

NASA GISS data

Global Sea Level: In the last century the Global sea level rose about 17 centimeters. Evidence suggests that it may be exponentially rising.

Global Surface Temperature: All three major global surface temperature reconstructions show that Earth has warmed since 1880.

Global Ocean Warming: The top 700 meters of ocean have shown a 0.2 degrees Celsius increase in temperature since 1969, suggesting that they are absorbing some of the heat.

NASA’s GRACE data

Shrinking Sea Ice: Data from NASA’s Gravity Recovery and Climate Experiment show Greenland lost 150 to 250 cubic kilometers of ice per year between 2002 and 2006, while Antarctica lost about 152 cubic kilometers of ice between 2002 and 2005.

Arctic Sea Ice Decline: Both the total coverage and the thickness of Arctic sea ice has been declining rapidly over the last several decades.

Glacial Retreat: The National Snow and Ice Data Center show that glaciers are retreating almost everywhere in the world, including the Alps in Europe, the Himalayas Asia, the Andes in South America,  across Alaska in North America, and Africa.

Extreme Events: The National Oceanic and Atmospheric Administration has a US Climate Extreme Index which notes that the number of record high temperature events in the United States has been increasing, while the number of record low temperature events has been decreasing, since 1950. The U.S. has also witnessed increasing numbers of intense rainfall events.

NOAA CO2 time series

Ocean Acidification: Since the beginning of the Industrial Revolution, the acidity of surface ocean waters has increased by about 30 percent. To learn more go to the NOAA page on What is Ocean Acidification? – The ocean is one of the lungs of our planet but it can’t keep working efficiently with the increasing level of material we are pumping into it and into our atmosphere.
