The current warming trend is of particular significance because most of it is extremely likely (greater than 95 percent probability) to be the result of human activity since the mid-20th century and proceeding at a rate that is unprecedented over decades to millennia.1

Earth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. This body of data, collected over many years, reveals the signals of a changing climate.

The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century.2 Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many instruments flown by NASA. There is no question that increased levels of greenhouse gases must cause the Earth to warm in response.

Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that the Earth’s climate responds to changes in greenhouse gas levels. Ancient evidence can also be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks. This ancient, or paleoclimate, evidence reveals that current warming is occurring roughly ten times faster than the average rate of ice-age-recovery warming.3

Here’s some fun facts about CO2 emissions.

The US has reduced its Carbon footprint by over 20% since it peaked in 2005.

The US doesn’t even rank in the top ten per capita on CO2 emissions anymore.

The US was set to pass Canada in per capita emissions in 2017 or 2018.

In 2017 EU emissions went up! While US emissions were down another 1.7%.

The US would be the one of the few to only country actually meeting Paris climate agreement numbers even though they were the only ones who chose not to participate.

Even if the US reduced it’s CO2 footprint to zero it wouldn’t matter because LoL China and India are increasing theirs so fast it has a net negative output.
