Compelling . . .

. . . science (without tin foil) . . .



(from https://climate.nasa.gov/evidence/)
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

Global temperature rise
The planet's average surface temperature has risen about 2.0 degrees Fahrenheit (1.1 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere. Most of the warming occurred in the past 35 years, with 16 of the 17 warmest years on record occurring since 2001. Not only was 2016 the warmest year on record, but eight of the 12 months that make up the year — from January through September, with the exception of June — were the warmest on record for those respective months. 6

Warming oceans
The oceans have absorbed much of this increased heat, with the top 700 meters (about 2,300 feet) of ocean showing warming of 0.302 degrees Fahrenheit since 1969

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 150 to 250 cubic kilometers (36 to 60 cubic miles) of ice per year between 2002 and 2006, while Antarctica lost about 152 cubic kilometers (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.8

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

Extreme events
Glaciers are retreating almost everywhere around the world; including in the Alps, Himalayas, Andes, Rockies, Alaska and Africa. 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.10

Ocean acidification
Since the beginning of the Industrial Revolution, the acidity of surface ocean waters has increased by about 30 percent. This increase is the result of humans emitting more carbon dioxide into the atmosphere and hence more being absorbed into the oceans. The amount of carbon dioxide absorbed by the upper layer of the oceans is increasing by 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

Finger. . .


. . . lakes


(from http://www.priweb.org/ed/finger_lakes/nystate_geo3.html)
The Finger Lakes consist of 11 long, narrow, roughly parallel lakes, oriented north-south as fingers of a pair of outstretched hands. The southern ends have high walls, cut by steep gorges. Two of the lakes (Seneca and Cayuga) are among the deepest in North America and have bottoms below sea level. These lakes all formed over the last two million years by glacial carving of old stream valleys. Ithaca is located at the south end of Cayuga Lake, the longest and the second deepest of the Finger Lakes. Cayuga is 38.1 miles long and 435 feet deep (53 feet below sea level) at its deepest spot. The actual depth of carved rock is well over twice as deep, but it has been filled with sediments; there may be as much as 1000 feet of glacial sediment in the deep rock trough below the lakebed.

The Finger Lakes originated as a series of northward-flowing rivers that existed in what is now central New York State. Around two million years ago the first of numerous continental glaciers moved southward from the Hudson Bay area, initiating the Pleistocene glaciation, commonly known as the "Ice age."

The most obvious evidence left by the glaciers are the gravel deposits at the south ends of the Finger Lakes called moraines and streamlined elongated hills of glacial sediment called drumlins. Moraines are visible south of Ithaca at North Spencer, along Route 13 west of Newfield, and near Willseyville. Drumlins are visible northeast of Ithaca at the northern end of Cayuga and Seneca lakes in a broad band from Rochester to Syracuse.
