Recently, on Twitter and Facebook I noticed graphs of climate change and its impacts being posted. These were often unaccompanied with data sources or links. A lot of misinformation occurs across the web in both denial and support of climate change. Beyond a shadow of doubt, anthropogenically caused climate change is occurring. However, we do the public no favors by posting graphs with uncited sources and complete transparency about sources and data. Below I provide 15 graphs of climate change providing their sources. Overwhelming they portray an alarming picture of changes on our planet. I chose only graphs that depict current or past changes. I specifically excluded projections and focused on patterns where the climate change link is not speculative.
I encourage you to post other graphs below as long as the meet my three criteria (reliable source, unspeculative connection, no projections) and you provide a source link. Anything that does not meet this criteria will be deleted. I will do a followup post with all of your suggestions. Also follow along on Twitter at #climategraphs
1. 2015 temperatures higher than warmest years on record
2. Current atmospheric carbon dioxide at highest in last 400,000 years
3. Direct measurements of carbon dioxide increases since 2005
4. Sea level increases since 1880
5. Arctic ice cover decreases since 1980
6. Increasing river discharge from melting snow packs into Arctic Ocean
7. Decreasing glacier mass from 1945-2014
8. Increasing sea surface temperatures since 1910
9. Increasing heat content of the oceans since 1955
10. Earlier last spring frost and later first fall frost from 1895-2014
11. Earlier blossoming of cherry trees in Washington, D.C.
12. Northward range shifts in British 6,669 plants
13. Northwards shifts center of abundance for North American birds from 1966 to 2014
14. Increases of thermal stress on Caribbean coral reefs
15. Increases in deaths classified as “Heat-Related” in the United States, 1979–2010

Craig Thank you so much this is exactly what I have been looking for. I am 73 but I have studied science at several universities and have taught multi-discipline science for decades at high school and tertiary level. I still consider myself to be a committed teacher. Substantiated evidence is essential otherwise it is just an opinion. i spent much time teaching teachers how to think. Thank you very much again!
