25-50% of the rainfall in the Amazon basin comes from the forest, and if deforestation reaches 30-40% most of the Amazon basin will enter a permanent dry climate. [14] In another article published by Nature, it points out that tropical deforestation can lead to large reductions in observed precipitation. [15]
A climate oscillation or climate cycle is any recurring cyclical oscillation within global or regional climate. They are quasiperiodic (not perfectly periodic), so a Fourier analysis of the data does not have sharp peaks in the spectrum. Many oscillations on different time-scales have been found or hypothesized: [23]

The Climate Attribution Database contains scientific resources organized by theme. [15] A study of 2020 storms of at least tropical storm-strength published in Nature Communications concluded that human-induced climate change increased extreme 3-hourly storm rainfall rates by 10%, and extreme 3-day accumulated rainfall amounts by 5%. [16]
A climate model is a representation of the physical, chemical and biological processes that affect the climate system. [172] Models include natural processes like changes in the Earth's orbit, historical changes in the Sun's activity, and volcanic forcing. [173]
The climate system will vary in response to changes in forcings. [15] The climate system will show internal variability both in the presence and absence of forcings imposed on it. This internal variability is a result of complex interactions between components of the climate system, such as the coupling between the atmosphere and ocean. [16]
Various factors affect the average state of the atmosphere at a particular location. For instance, midlatitudes will have a pronounced seasonal cycle of temperature whereas tropical regions show little variation of temperature over a year. [20] Another major variable of climate is continentality: the distance to major water bodies such as oceans.
The climate of a location is affected by its latitude, longitude, terrain, altitude, land use and nearby water bodies and their currents. [3] Climates can be classified according to the average and typical variables, most commonly temperature and precipitation. The most widely used classification scheme is the Köppen climate classification.
