Mean air temperature and annual rainfall , are increasing, combined with an increase in seasonality  and extreme weather events, particularly higher levels of precipitation . Two impacts related to warmer air conditions are the displacement of the freezing line currently placed at 5100 MASL , followed by glacier retreat and the upward displacement of mountainous ecosystems  . The key ecosystem that regulates water provision for the city is the paramo, and only about 5% of this process is related to glaciers, so the combined effects of climate change on both systems, coupled with land use change and fires, can reduce the availability of water for agriculture, human consumption and hydropower. Other important climatic hazards and impacts are the increase of solar radiation, the heat island effect and fires  . On almost half of the days of each year, Quito's population is exposed to levels of UV radiation above 11 according to the World Health Organization scale .
