This study presented in the article directly correlates with a series of sustainable objectives regarding the causes of climate change in the Republic of Moldova and their consequences. For more than 100 years, specialists have known the meaning of the phrase "greenhouse effect". This process contributes to maintaining a warm atmosphere, preventing the Earth from cooling and becoming hostile to life (the average global temperature is + 15°C versus - 18°C in the absence of this natural greenhouse effect). Of course, a drastic way in the influence of climate change is effected by burning forests - made to obtain arable land, roads, housing or shopping centers - produces over 25% of global carbon dioxide emissions. The conclusion that can be drawn very easily is that the current heating is not caused by an intensification of the solar activity, but it is in close correlation with the emission of carbon dioxide. In the Republic of Moldova, the inventory of greenhouse gas emissions was carried out during the years 1990-2002, the reference year recommended by the UN being 1990. During this research period, the main place of the total emissions belongs to it CO2. There is a considerable decrease in greenhouse gas emissions. The cause of the decrease is the closure of emission sources: factories, factories, etc. Comparative assessments with other neighboring territories, using data from the Center for Epidemiological Research of Natural Hazards (Belgium, Luviana University) allow us to ascertain that the risk of catastrophic flooding is 1-2 times in 10 years, which is less than in some regions of Romania, where they have the frequency of 2-3 times in 10 years. Systematic observations on climate indices in the Republic of Moldova, initiated since 1986, have shown gradual warming as a consequence of global warming. Climate change that has occurred over the years in the Republic of Moldova seems to have significant impacts on biodiversity, starting with the level of individual law and up to the level of ecosystem or biometrics.
