According to the National Oceanic and Atmospheric Administration, global average surface temperatures for the first three months of 2018 have eased off of their record-breaking streaks seen in recent years, with January and March each being only the fifth warmest months for their respective months, and February coming in as the 11th hottest February in the 139-year record. While this trend looks good on the surface, NOAA points out that each of these months’ temperatures are still well above the 20th century average, meaning we’re still far from out of the global warming gutter.

The National Aeronautics and Space Administration has released an animation on their website that illustrates how average global surface temperatures have risen since record-keeping started in the late 19th century. The video helps to visually illustrate the rise of Earth’s temperatures, spanning a 135-year period from when temperature records were first recorded, in 1880, through 2015, the hottest year on record.

The baseline average used in the video was derived from temperature averages from 1951 through 1980, with blue colors representing below-average trends, and orange representing above average temperatures.

The National Oceanic and Atmospheric Administration also released a similar video, showing the same warming trend over the past 135 years. read more

In comparison to geological timescales, human documentation of geological events only extends back into a mere fraction of the Earth’s past: the oldest-known depiction of a volcanic eruption is found in Turkey, in a mural dating back to 6,600 BCE. But according to a new paper published in the journal PLoS ONE, that date may have just been pushed back even further, by a scene painted in France’s Chauvet-Pont D’Arc cave.

Discovered in 1994, Chauvet-Pont D’Arc cave is the home to an extensive gallery of Paleolithic cave art, created over a number of periods between 23,000 and 36,000 years ago. The illustrations in this cave are the earliest known examples of human art, documenting the evolution of mankind’s artistic expression.

The National Oceanic and Atmospheric Administration has released their year-end report on the planet’s average temperatures, and 2015 has proven to the warmest year since record keeping began in 1880 — by a wide margin. The year also left a trail of multiple broken temperature records in it’s wake, for both yearly and monthly records over land, sea, and combined averages.

2015’s global average temperature was a full 1.62ºF (0.90ºC) above the 20th century average, and it beat 2014’s record temperature by 0.29ºF (0.16ºC). This margin is also a record, in-of-itself, being the widest observed margin on record.
