Climate is the atmospheric changes and weather patterns of a given place over many years. For the last 150 years, humans have become accustomed to a new global temperature term of “the new normal." Global temperatures have changed by approximately 1 degree Fahrenheit (0.7 degree C) since 1900. In addition, the level of warming since the late 1970s has been about three times greater than the century-scale trend. Therefore, I do not think the last 150 years represent anything unusual in the history of the earth’s climate. Although the 150-year global temperatures show a lot of variation, this period can be classified into several major seasons. The Earth experienced a roughly constant average temperature in the 19th century, a temperature increase in the early 20th century, a stabling or a minor decline in the mid-20th century and a sharp increase towards the end of 20th century progressing into the 21st century. Climate has been different in the course of the planet’s history. However, certain features of the present-day climate alteration are not extraordinary, while the rest are.
Therefore, in order to conclude and say that the last 150 years global temperature record represents anything unusual in the history of the Earth’s climate, it would be important to have clear variables being compared. First, it is important to state whether it is the greenhouse effect or temperature and whether their total values or the proportions of their alteration are being compared. Second, it will be important not to mix local changes and global changes. Third, before making a conclusion, it will be essential to distinguish time periods and sequences. Climate alteration over many centuries can be caused by activities such as continental drift paralleled to weather patterns transformation on a continental time scale. While the early part of the 150-year temperature change can be largely explained by natural variations within the climate system, variations in the recent decades are largely a result of human activities.
