The Water Cycle
Viewed from space, one of the most striking features of our home planet is the water, in both liquid and frozen forms, that covers approximately 75% of the Earth’s surface. Geologic evidence suggests that large amounts of water have likely flowed on Earth for the past 3.8 billion years—most of its existence. Believed to have initially arrived on the surface through the emissions of ancient volcanoes, water is a vital substance that sets the Earth apart from the rest of the planets in our solar system. In particular, water appears to be a necessary ingredient for the development and nourishment of life.

Water, Water, Everywhere
Water is practically everywhere on Earth. Moreover, it is the only known substance that can naturally exist as a gas, a liquid, and solid within the relatively small range of air temperatures and pressures found at the Earth’s surface.

World water statistics reveal both progress and challenges in ensuring access to clean water worldwide. According to recent data, around 785 million people still lack basic access to clean water, with millions more lacking access to adequate sanitation. Moreover, water scarcity affects over 2 billion people, with the situation exacerbated by climate change and population growth. Despite these challenges, there has been progress, with an estimated 2.6 billion people gaining access to improved drinking water sources since 1990. However, sustaining this progress requires continued investment in infrastructure, conservation efforts, and equitable distribution of water resources.

climate change

The Global Forest Watch analysis found deforestation in 2022 was more than 10,000sq km (3,900sq miles) in excess of what is needed to halt it entirely by 2030. That is nearly a football pitch of mature tropical trees felled or burned every five seconds, night and day, and 10 percent more than the year before.

The global mean sea level (GMSL) in 2022 was the highest ever measured. GMSL reconstructions based on tide gauge observations show a rise of 21cm from 1900 to 2020 at an average rate of 1.7mm/year.

It provides water when precipitation is at its lowest and refills natural and built reservoirs. About a quarter of the world relies on the water stored in mountains. But climate change is putting this cycle at risk. Warmer temperatures shrink the existing snowpack and produce storms that dump more rain instead of snow.
