Answer:
Global warming, the phenomenon of increasing average air temperatures near the surface of Earth over the past one to two centuries. Climate scientists have since the mid-20th century gathered detailed observations of various weather phenomena (such as temperatures, precipitation, and storms) and of related influences on climate (such as ocean currents and the atmosphere’s chemical composition). These data indicate that Earth’s climate has changed over almost every conceivable timescale since the beginning of geologic time and that the influence of human activities since at least the beginning of the Industrial Revolution has been deeply woven into the very fabric of climate change.
changes in global average surface temperature and sea level and Northern Hemisphere snow cover
changes in global average surface temperature and sea level and Northern Hemisphere snow cover
During the second half of the 20th century and early part of the 21st century, global average surface temperature increased and sea level rose. Over the same period, the amount of snow cover in the Northern Hemisphere decreased.

DID YOU KNOW?
In the last decade, the rate of Antarctica's ice mass depletion has tripled.
Surface ocean waters today are roughly 30 percent more acidic than at the start of the Industrial Revolution.
Scientists predict that the Arctic Ocean will barely have ice before 2050.
For the last twenty years, sea levels rose at twice their rate during the last century.
Global temperatures could increase by as much as 10.4 degrees Fahrenheit by 2100.
Giving voice to a growing conviction of most of the scientific community, the Intergovernmental Panel on Climate Change (IPCC) was formed in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Program (UNEP). In 2013 the IPCC reported that the interval between 1880 and 2012 saw an increase in global average surface temperature of approximately 0.9 °C (1.5 °F). The increase is closer to 1.1 °C (2.0 °F) when measured relative to the preindustrial (i.e., 1750–1800) mean temperature.
