By far the best observed period is from 1850 to the present day, with coverage improving over time. Over this period the recent instrumental record, mainly based on direct thermometer readings, has approximately global coverage. It shows a general warming in global temperatures. Before this time various proxies must be used.
Global warming occurs when earth receives more energy than it gives back to space, and global cooling takes place when the outgoing energy is greater. [3] Multiple types of measurements and observations show a warming imbalance since at least year 1970. [4] [5] The rate of heating from this human-caused event is without precedent.
Scientists warn that if carbon dioxide and other greenhouse gas emissions continue to rise at their current rates, Earth’s temperatures could increase dramatically in future decades, leading to catastrophic and irreversible climate change. The 10 largest emitters produced about 26.4 gigatons of carbon dioxide in 2013.
