How Global Warming is Fueling More Frequent Natural Disasters

Today, if you are to turn on the news, you are undoubtedly going to hear of a flood, a wildfire, or a hurricane scaring some part of the world. These disasters are no longer unusual, they are becoming shockingly usual. The pattern is Global warming, the rise of Earth's average temperature caused almost entirely by the activities of humans.

Scientists have long since been clear that climate change does not simply mean hotter summers, it interferes with natural systems and causes an increase in extreme weather patterns. Warmer oceans energize storms, rising heat dries out trees and brush until they combust, and melting sea ice, which raises sea levels and floods previously dry areas.

In this blog, we will consider the way global warming leads to more frequent natural disasters, the science behind these changes, and what we must do to help protect ourselves and the planet.

Understanding Global Warming

Global warming is simply the slow increase of the average temperature of Earth. A slight variation may not seem problematic but when we alter the temperature by 1°C we are changing the balance of the planet.

This warming has indeed been brought about principally by the greenhouse effect; the gases have trapped heat in the Earth's atmosphere, much like a warm blanket for the planet: carbon dioxide (CO2 being the chief amongst them), methane, nitrous oxide. Man-made activities, such as burning coal for generation of energy, oil and gas, cutting down forests, or just maybe, industrialization abroad, generate these gases faster than nature can dispose of them.

As a result, we are seeing changes to the through mechanisms of the planet, changes to weather patterns, higher frequency and intensities of heatwaves, melting of ice caps and rising sea levels. Warming of the Earth is leading to an increase in natural disasters in terms of frequency and intensity.

Global Warming and Extreme Weather Events

With the rising temperatures of the earth, the weather is becoming increasingly unpredictable, with an added measure of danger. Global warming acts as a fuel to the storms, floods, droughts, and wildfires which are forecasted to last longer, and burn hotter.

Where it rains, it rains heavily - mostly because warmer air can hold larger quantities of water vapor; when this rain comes, it comes as event rain, with sudden floods/flooding, and flash flooding. But the heat that supports this massive rainfall also dries out the soils and vegetation, which creates an environment for droughts and wildfires. The warmer oceans are also strengthening hurricanes , cyclones and similar systems, making them stronger than ever.

The proof is there for all to see. A few recent climate studies suggest that the episodes of extreme weather have doubled almost in the past few decades. Global warming is not a faraway problem anymore. It is already affecting us, from extreme heat in Europe to big floods in Asia.

How Global Warming Fuels Specific Disasters

Not all disasters felt the effects of global warming in the same manner. Some disasters will feel disastrous effects considering that they rely more directly on rising temperatures and/or shifting weather patterns. Here is how specific natural disasters magnify disaster through global warming:

• Stronger Cyclones & Hurricanes: Warmer sea surface temperatures all serve as extra fuel in storms. With warmer sea temperatures, coming off warmer oceans , the storm stronger, hurricanes, cyclones all increase in destruction and duration.
• Extended Heatwaves & Wildfires: The rise in global temperatures pushes longer periods of heatwaves, drying forests and grasslands. This heat causes larger length and more frequent Wildfires, affecting properties, lives, and lives.
• Floods and heavy rain: Warmer air holds potentially more moisture so even if it is a brief event it can be heavy rain. Heavy rain over a short period of time may fall when river levels and/or road drainage systems are already high which could lead to even more flooding or even landslips.
• Melting glaciers, sea level rise: Glaciers and any level of ice caps are melting quicker pushing sea levels higher. Although coastal communities are familiar with flooding occurring at a certain height, they are now more frequent with rising sea levels.
