Climate science has been around since the 1900's. Everyday more and more research is being done and yet there are still climate change deniers out there, it makes very little sense to anyone involved in climate science, or anyone that can use logic and common sense for that matter.
People that deny climate change are having a disastrous effect on our planet that is irreversible, cities and countries around the globe will be underwater within a few decades, its inhabitants forced to move inland. Entire islands will disappear from the face of the earth, only to be found in history books and old maps, and yet still people can't seem to accept its occurrence.
Below is a brief history of climate science beginning in 1824 until present. This is far from complete but includes some of the more important findings of climate science thus far.
1824 - Joseph Fourier discovered the greenhouse effect.
1859 - John Tyndall discovered that H2O and CO2 absorb infrared confirming the Fourier greenhouse effect.
1896 - Svante Arrhenius proposed human CO2 emissions would prevent earth from entering next ice age (challenged 1906).
1950’s Guy Callendar found H2O and CO2 did not overlap all spectra bands, therefore warming from CO2 expected (countered the 1906 objections against Arrhenius).
1955 - Hans Suess identified the isotopic signature of industrial based CO2 emissions.
1956 - Gilbert Plass calculated adding CO2 would significantly change radiation balance.
1957 - Revelle/Suess suggested oceans would absorb less CO2 causing more global warming than predicted.
1958/60’s - Charles David Keeling proved CO2 was increasing in the atmosphere.
70’s/80’s Suke Manabe and James Hansen began modeling climate projections.
Current: Glacier Melt, Sea Level Rise, Latitudinal Shift all confirm models.
Currently every country on earth has signed onto the Paris agreement which " is an agreement within the United Nations Framework Convention on Climate Change (UNFCCC) dealing with greenhouse gas emissions mitigation, adaptation and finance starting in the year 2020" with only one exception... The United States of America.
For some ludicrous reason Donald Trump has withdrawn the U.S from the Paris agreement which is fairly devestating given they are one of the largest countries responsible for warming.

His withdrawal has drawn widespread criticism from both international and domestic parties, labeling him incredibly environmentally ignorant. If something isn't done soon the whole world will suffer the consequences and Mr. Trump for some reason doesn't believe this.
Well, i say good luck to us all because we're sure as hell gunna need it.
