Around 30% of Earth's land area is largely unusable for humans (glaciers, deserts, etc.), 26% is forests, 10% is shrubland and 34% is agricultural land. [125] Deforestation is the main land use change contributor to global warming, [126] as the destroyed trees release CO 2, and are not replaced by new trees, removing that carbon sink. [127]
“Hot drought” — when extreme drought and heat occur simultaneously — has increased in severity and frequency over the last century due to human-caused climate change, according to a study ...

The tropical storm that was always going to form in the ocean, but might have subsided before, more frequently turns into a powerful hurricane that pummels all it touches and leaves major ...
