Humans are the main cause of global warming

Thanks to my opponent for a well written response. I.i. The rest of the solar system While fluctuations in solar activity can affect Earth's climate, the majority of climate scientists and astrophysicists agree that the sun is not to blame for the current and historically sudden uptick in global temperatures on Earth, which seems to be mostly created by humans. [1] Abdussamatov blamed solar fluctuations for the attenuation of ice caps on Mars. However, these changes were likely not due to the Sun, but rather increases in atmospheric clouds or aerosols that reflected solar radiation back into space.[1] Charles Long, a climate physicist at Pacific Northwest National Laboratories in Washington, says that Abdussamatov's idea is nonsense. [1] I.ii. The Position of the Milky Way Galaxy "Every approximately 135 million years, Earth enters a more populated area of the Milky Way, and as a result, more cosmic rays hit the Earth, which causes cooling." 135 million years. Wikipedia says: "Global warming is the rise in the average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth's mean surface temperature has increased by about 0.8 "C (1.4 "F)."[2] This was nowhere near 135 million years. How could this suddenly happen? II. Earthly causes I.i. Ocean Current Anomalies "Ocean temperature anomalies seem to be rising-along with the temperature." The temperature of the ocean can also be affected by the CO2 and Methane levels, (Which I proved that were going up in the last round. ) as those warm the surface and air, won't it be plausible that the air is warming the oceans and not the other way around? Plus, In the picture you posted, it DID affect the temperature, but it still was going up, which I proved was man made. II.ii. Clouds: A Continuation of Point I.ii. See my refutation on Point I.ii. III. The 1500-Year Cycle I.S.I.L. is not even a scientific organization at all. " The International Society for Individual Liberty (ISIL) is an association of individuals and organizations dedicated to building a free and peaceful world, respect for individual rights and liberties, and an open and competitive economic system based on voluntary exchange and free trade. ISIL currently has members and representatives in over 100 countries."3] I.S.I.L. even said "To combat global warming, militants say we must all accept drastic reductions in our standard of living starting now, steadily increasing year-after-year, until much of industrial society is swept away. Only thus can the earth, and perhaps mankind, be saved. Cars, jet travel for the public, air conditioning, refrigeration, and indeed many if not most of the conveniences of modern life will simply have to be abolished, as quickly as politically feasible. " Even though that is not true. "Industrialized countries commit to reduce their emissions by 40% by 2020, compared to 1990 levels. Emissions from forest destruction are reduced by three quarters (75%)Emissions from forest destruction are reduced by three quarters (75%)" [4] IV.
