Killing The NASA Messenger

In the ongoing program of systematic destruction of everything America stands for, the “America Great Again” fiasco has cancelled NASA funds for anything which might counter the illusion that climate change deniers promote. This includes satellites that are allowed to collect data looking away from Earth but funding to collect and analyze data collects in the direction of Earth has been cut. Before our Big Brother administration has it removed from public access, check out NASA findings on https://climate.nasa.gov/evidence  They are summarized below beginning with this fundamental chart of carbon dioxide levels.

The Earth’s climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat. The abrupt end of the last ice age about 7,000 years ago marks the beginning of the modern climate era — and of human civilization.

The current warming trend is significant because it is predominantly the result of human activity since the mid-20th century and it is proceeding at an unprecedented rate.

Earth-orbiting satellites and other technological advances enable scientists to collect many different types of information about our planet and its climate on a global scale. This body of data, collected over many years, reveals serious climate change. Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that the Earth’s climate responds to changes in carbon dioxide levels. Ancient evidence can also be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks. This ancient evidence reveals that the Earth is warming roughly ten times faster than the average rate of ice-age-recovery.

Sea level rise
Global sea level rose about 8 inches in the last century. The rate in the last two decades, however, is nearly double that of the last century. It is estimated that disappearance of polar ice caps will raise the ocean level to the Statue of Liberty’s elbow.

Global temperature rise
The planet’s average surface temperature has risen about 2.0 degrees Fahrenheit since the late 19th century, a change driven largely by increased carbon dioxide and other man-made emissions. Most of the warming occurred in the past 35 years, with 16 of the 17 warmest years on record occurring since 2001.

Warming oceans
The oceans have absorbed much of this increased heat, with the top 2,300 feet showing warming of 0.302 degrees Fahrenheit since 1969. We see the effect in stronger and more frequent hurricanes brewed each year.

Shrinking ice sheets
The Greenland and Antarctic ice sheets have decreased in mass. Data from NASA’s Gravity Recovery and Climate Experiment show Greenland lost 36 to 60 cubic miles of ice per year between 2002 and 2006, while Antarctica lost about 36 cubic miles of ice between 2002 and 2005.

Declining Arctic sea ice
Both the extent and thickness of Arctic sea ice has declined rapidly over the last several decades.

Glacial retreat
Glaciers are retreating almost everywhere around the world — including in the Alps, Himalayas, Andes, Rockies, Alaska and Africa.

Extreme events
The number of record high temperature events in the United States has increased, while the number of record low temperature events has decreased, since 1950. The U.S. has also witnessed increased intense rainfall events and floods. And on the other end of the spectrum, severe droughts and massive fires.

Ocean acidification
Since the beginning of the Industrial Revolution, the acidity of surface ocean water has increased by about 30 percent. It is caused by absorption of increased carbon dioxide in the air, an increase of about 2 billion tons per year.

Decreased snow cover
Satellite observations reveal that the amount of spring snow cover in the Northern Hemisphere has decreased over the past five decades and that the snow is melting earlier.

These are the factors behind the rise in disasters we now see each year. The evidence is as clear as that which proved the earth is round

Unfortunately, deniers prefer to believe what other deniers claim rather than facts. It’s the same phenomenon that led otherwise sane people in Germany and Kosovo to murder their neighbors and previous family friends.
