The moon has always influenced the tides, following an 18.6-year oscillating cycle. During the first half of the cycle, the difference between high and low tides is reduced, while in the second half, it is amplified. In 2030, rising sea levels caused by global warming, combined with the second phase of the cycle, led to the flooding of many coasts and the abandonment of several cities. That’s when Moondo travel agency was born. Taking advantage of these new environmental conditions, Moondo transformed submerged cities into unique tourist destinations. It offers a variety of activities, including acqua trekking in shallow waters, kayaking, paddle surfing, snorkeling and scuba diving. Moondo turns what would have been deserted ruins into some of the most fascinating places to explore. In a constantly changing world, Moondo turns catastrophic conditions into one-of-a-kind experiences, offering travellers unforgettable vacations in the most unexpected places.







Since the Industrial Revolution, the burning of fossil fuels like coal, oil, and gas has led to increased greenhouse gas emissions, trapping heat in the atmosphere and causing global warming. Key consequences include rising global temperatures, melting glaciers, and extreme weather events such as droughts and floods. Over the past century, the Earth’s temperature has risen by approximately 0.98°C compared to pre-industrial levels, with projections of further increases if emissions continue unabated.

One of the most concerning outcomes of global warming is the rise in sea levels. This phenomenon is primarily caused by the melting of polar ice caps and the thermal expansion of seawater as it warms. Between 1993 and 2023, global sea levels rose by nearly 10 centimeters and are expected to increase by an additional 30 centimeters by 2050, impacting millions of coastal inhabitants worldwide.
While the moon has always influenced Earth’s tides through gravitational pull, its orbit undergoes an 18.6-year oscillation known as the lunar nodal cycle. This cycle alternates between phases that either dampen or amplify tidal effects. During the amplification phase, high tides become even higher, while low tides dip further. In combination with rising sea levels, the moon’s amplified tidal effects are predicted to exacerbate coastal flooding starting around 2030.
