The document summarizes the main points from a reading and lecture about models and predictions of global warming, and the discrepancies between them. A group of government scientists say evidence from computer models and satellite data shows rising air and ocean temperatures, rising sea levels, and less CO2 being absorbed by the atmosphere. However, natural cycles like El Niño and La Niña affect temperatures yearly. Other scientists question the results, claiming evidence that does not match models or is different from government data is enough to say the models cannot be fully relied upon. Areas of disagreement include how well models simulate clouds, the accuracy of satellite temperature measurements, and differences between ocean surface and subsurface temperatures. More needs to be considered before making definitive statements about global warming
