A Century of Warming: Reviewing Global Temperature Trends, Regional Patterns, and Climate Futures

Abstract

The planet is slowly warming and the evidence is all around—albeit not so obvious as it is today. The planet is communicating to us that change is under way: melting glaciers, sweltering cities. This review illustrates the changes in temperatures throughout the world using extensive data and models. We learn that the world has experienced little more than a 1 degree Celsius rise in temperature since the close of the 19th century, but there is more to this story.

They are not warming equally and some areas are warming twice as fast as others, particularly in the Artic and mountain areas. Cities are suffering from the effects of the urban heat island effect that heat-absorbing concrete and glass surfaces cause. These temperature variations do not only reflect statistics but have significant practical impacts, such as altered ecosystems, disappearing glaciers, intensified heatwaves, stressed food production systems and growing risk to human well-being and water supplies.

If we make wise decisions now, we will have a bright future. Climate model simulations indicate that if climate action is taken boldly, the level of warming can be restricted to under 1.5°C. The solutions offered, however, if not adapted for the context and culture they're intended for, may carry unpredictable and significant consequences for the planet if adopted as is. Understanding temperature trends is not simply a matter of numbers - it is an issue of preparedness for the future, according to this paper. Science is clear, time is short, and it's our responsibility. The decisions we make today will impact the world for generations to come.
