Nicolae Testemianu State University of Medicine and Pharmacy, Republic of Moldova Introduction. Although nowadays multiple scientific organisations have shown solid evidence that Earth is going through global warming, some stories prove vice-versa, their main argument being those 2 years studies shown by NASA in data. However, you can’t state the fact that our planet is going through global cooling based on such a short period. Studies have shown that on a larger time scale, atmosphere temperature can be explained using the Keeling Curve, which is a long-term study of CO2 concentrations-the higher the concentration, the higher the temperature. And even if this curve is constantly jiggling up and down, meaning that the temperature during short periods such as a few years is either increasing or decreasing, the overall direction is an increase, meaning that slowly but steadily, Earth is warming on a global scale. Material and methods. This research analysed the major aspects of global warming, using data provided by trustworthy scientific organisations, such as the Natural Resources Defence Council, National Geographic, NASA and others which have studied this field for a prolonged time. There have been avoided platforms that offered information without any reference to sources. Results. Scientists generally regard the second half of the 19th century as the starting point of humanity influencing the global climate. How much of the warming since 1850 can be attributed to human emissions? Almost all of it. The intergovernmental Panel on Climate Change stated that greenhouse gas emissions are at an unprecedented level in the last 800.000 years, and the ones at fault are none other than humans. The interdependence between carbonic acid gas and global temperatures have been confirmed during Earth’s history. During the last 800.000 years, there have been CO2 fluctuations, which were periodically higher or lower and the main cause were the changes of Earth’s orbit around the sun, also known as Milankovitch Cycles. ...
