A major ongoing threat to our planet is global warming. One of the main implications of global warming is the aridification of the continents, which is when a region becomes dry. Both natural (e.g., higher temperature, reduced precipitation, increased evaporation) and human influenced changes (e.g.,... click to read more

Climate change is accelerating ocean warming globally, and heat waves are becoming more frequent and intense. This is of great concern as heat is a deadly threat to aquatic animals. But the extent of danger depends – some fish species are more heat-tolerant than others.... click to read more

Looking at satellite images or Google Earth, you often find continent-long elongated clouds covering our planet, which may look like "rivers" running through the sky. These rivers are narrow belts of concentrated moisture in the atmosphere. Atmospheric rivers extend from the tropics (where water tends... click to read more

Today's climate change is driving geological changes such as coastal erosion and expansion of arid areas. It is also threatening our planet. Such dramatic climate changes happened before in the planet's history. These past events may teach us to forecast what the ongoing events are... click to read more

Glaciers around the world are melting faster than in any previous decade since measurements began. Glaciers form when snow accumulates over many years and compresses into ice. Glaciers accumulate snow in the winter, and then melt ice in the summer. Cold temperatures, more snow, or both,... click to read more
