NASA | 2014 Warmest Year On Record

NASA's Goddard Institute for Space Studies releases an annual global temperature analysis using data from weather stations worldwide. The analysis shows a significant increase in Earth's temperature since 1880, with a 1.4°F rise in the global average. This change, though seemingly small, is crucial for climate understanding. Temperature fluctuations occur yearly due to weather patterns, but the long-term trend shows rising temperatures, as seen in 2014, the hottest year on record. This trend is driven by increased carbon dioxide levels from burning fossil fuels, contributing to the greenhouse effect and global warming.

What is the significance of the 1.4 degrees Fahrenheit increase in global average temperature since 1880?

• It indicates a minor change in climate.

• It shows a significant impact on climate.

• It reflects stable global temperatures.

• It suggests a decrease in global temperatures.

Which year was noted for having extreme weather patterns, with both cold and hot records in the US?

• 2016

• 2014

• 2012
