NASA has published a study that warns that, by 2050, areas of Spain such as Madrid, Valencia and Andalusia will experience extreme conditions due to climate change, both heat, droughts and floods that will make them difficult to live in. The volume will decrease by 10%, adding to the water shortage, as warned by the UN and Greenpeace. Madrid, Valencia and Andalusia will be the most affected areas by global scalding, extreme heat, fires, droughts and floods. It will also affect other areas such as the north of the peninsula, the Canary Islands and the Balearic Islands.
Until today, no major city has been completely abandoned or declared uninhabitable due to global warming. However, the impact of climate change has begun to make certain areas of the world increasingly difficult to inhabit. These effects include rising sea levels, extreme heat waves, droughts, and more. But some cities have and are experiencing similar situations. Cities and regions like: Lagos (Nigeria), Venice (Italy), Bangkok (Italy) or Alexandria (Egypt).
Although the climate has changed throughout history, this rate of change hasn’t had a precedent in millennia. In the past 800,000 years, there have been only eight cycles of ice ages and warmer periods, with the last ice age being about 11,700 years ago. Most of these climate changes are attributed to very small variations in the Earth’s orbit that change the amount of solar energy our planet receives. But now, the reason for the current warming is different because it is the result of human activities since the mid-19th century. Human activities have produced atmospheric gases that have trapped more of the Sun’s energy in the Earth system. This additional energy has warmed the atmosphere, ocean, and land.
