The Importance of Historical Temperature Trends The history of human development is intricately linked with global warming. While part of the rise in Earth’s surface temperature can be attributed to natural patterns of climate change, these historical trends shed some light on how much human activit...
This time-series graph plots global temperatures from 1850-2023 versus the 20th century average. 2023 stands out as the hottest year in that 173-year record. The temperature anomaly label for 2016 has been added to the graph to show how much hotter ...
USA. This time series is calculated using land surface data from theGlobal Historical Climatology Network(Version 2) and sea surface temperature anomalies from theUnited KingdomMOHSSTdata set and the NCEP Optimum Interpolated SSTs (Version3;note version changeon May 2, 2011)....
As an illustration of the sometimes questionable effects of temperature adjustments, consider the United States data (almost 30 percent of the world’s total historical climate stations are in the US; rising to 50 % of the world’s stations for the post-1990 period). The following graphs show...
Of the three scenarios, the middle one, which corresponds most closely to actual historical carbon emissions, comes closest to matching the observed warming of roughly 0.5 °C (0.9 °F) that has taken place since then. The NASA team also used a climate model to successfully predict that ...
Examines the science and arguments of global warming skepticism. Common objections like 'global warming is caused by the sun', 'temperature has changed naturally in the past' or 'other planets are warming too' are examined to see what the science really
larger graph FromTemperature Anomaly FAQs: The term “temperature anomaly” means a departure from a reference value or long-term average. A positive anomaly indicates that the observed temperature was warmer than the reference value, while a negative anomaly indicates that the observed temperature was...

A graph showing global temperatures for the ten hottest years on record.(Image credit: NOAA) One of the most immediate and obvious consequences of global warming is the increase in temperatures around the world. The average global temperature has increased by about 1.4 degrees Fahrenheit (0.8 degr...
It's just a change in average temperature. Global warming graphs show how historical temperatures fluctuated by much more than we're seeing now, according to a lot of articles and websites. The earth has survived global warming. There is some question about whether mankind will survive many of...
