Climate change denotes a long-term change (normally for decades or longer) of the climate state that can be acknowledged through statistical methods (e.g. variability and/or the average of its properties) and have come to outline local, regional and global climates. Climate change can be triggered by natural processes, or by continuous anthropogenic modifications in land use/cover or in the atmosphere composition. Changes witnessed in the last century are mainly motivated by human actions (e.g. burning fossil fuel) that increased greenhouse gas concentration in the atmosphere and lead to the increase of average surface temperature (Masson- Delmotte et al., 2021; Overview: Weather, 2020). Globally, an increase of 1°C in the average temperature since the beginning of the 20th century, has resulted in additional risks (Haustein et al., 2017; IPCC, 2018), such as emerging infectious diseases in areas unaffected before (Legendre et al.; Watts et al., 2015), persistent drought and heatwaves, severe storms and floods, and threats to food security.engClimate changeEconomyHealthEnvironmentbook part
