10 Deadliest Effects of Global Warming

10 Deadliest Effects of Global Warming

1. Global Warming effects

Greenhouse gases can stay in the atmosphere for an amount of years ranging from decades to hundreds and thousands of years. No matter what we do, global warming is going to have some effect on Earth. Here are the 5 deadliest effects of global warming.

2. Warmer waters and more hurricanes

As the temperature of oceans rises, so will the probability of more frequent and stronger hurricanes. We saw in this in 2004 and 2005.

 

3. Increased probability and intensity of droughts and heat waves

Although some areas of Earth will become wetter due to global warming, other areas will suffer serious droughts and heat waves. Africa will receive the worst of it, with more severe droughts also expected in Europe. Water is already a dangerously rare commodity in Africa, and according to the Intergovernmental Panel on Climate Change, global warming will exacerbate the conditions and could lead to conflicts and war.

4. Economic consequences

Most of the effects of anthropogenic global warming won’t be good. And these effects spell one thing for the countries of the world: economic consequences. Hurricanes cause billions of dollars in damage, diseases cost money to treat and control and conflicts exacerbate all of these.

  

5. Polar ice caps melting

The ice caps melting is a four-pronged danger.

First, it will raise sea levels. There are 5,773,000 cubic miles of water in ice caps, glaciers, and permanent snow. According to the National Snow and Ice Data Center, if all glaciers melted today the seas would rise about 230 feet. Luckily, that’s not going to happen all in one go! But sea levels will rise.

Second, melting ice caps will throw the global ecosystem out of balance. The ice caps are fresh water, and when they melt they will desalinate the ocean, or in plain English – make it less salty. The desalinization of the Gulf current will “screw up” ocean currents, which regulate temperatures. The stream shutdown or irregularity would cool the area around Northeast America and Western Europe. Luckily, that will slow some of the other effects of global warming in that area!

Third, temperature rises and changing landscapes in the Artic Circle will endanger several species of animals. Only the most adaptable will survive.

Fourth, global warming could snowball with the ice caps gone. Ice caps are white, and reflect sunlight, much of which is reflected back into space, further cooling Earth. If the ice caps melt, the only reflector is the ocean. Darker colors absorb sunlight, further warming the Earth.

6. More floods

Flooding represents one of the most dangerous hazards to human settlements and is one of the most potentially momentous impacts of global warming. As the climate changes, a warming of the seas creates ‘thermal expansion’. This is where warm water begins to take up more space than cool water, making the sea’s surface level increase. Thermal expansion has already raised the height of the oceans by 4 to 8 inches (10 to 20cm), according to National Geographic.

Steadily melting glacial ice also adds significantly to the elevation in water surface level, and many low-lying or coastal communities and facilities will be under threat of eradication should the sea levels continue to rise. An increase of just a single meter (3 ft) would submerge considerable sections of the U.S. eastern seaboard, while one sixth of Bangladesh could be lost permanently by a rise of 1.5 m (5 ft), to name just two examples.

The relocation of power stations, refineries, hospitals, homes and so on would become an expensive priority. Also, warmer air can hold more water vapour, increasing the level of rainfall and bringing flooding to inland areas.

7. Fires and wildfires

As the planet continues to warm, dry areas of land that are already susceptible to wildfires are likely to be ravaged by even more frequent and destructive episodes. In 2007, more than 3,000 fires brought destruction to Southeastern Europe thanks to a long summer that created arid and parched conditions – a situation that would become normal as a consequence of the greenhouse effect.

What’s more, the carbon dioxide and ‘black carbon’ (a very fine soot) released by these large-scale fires together with the deforestation they cause further compounds the problem of air pollution – as the gases that help to create the greenhouse effect are supplemented and less mature trees survive to draw CO2 from the atmosphere.

8. Destructive storms

With ocean temperature being a key factor for hurricane formation, the consequences of global warming will inevitably include the increased generation of storms and hurricanes with greater power and frequency.

The destructive power of hurricanes has increased by some 50% in the last 30 years, a figure that is closely connected with the rising temperature of the ocean. Warmer water leads to greater evaporation, which in turn helps to not just ‘prime’ the coalescence of hurricanes and cyclones but also to maintain their vigour once extant.

Simply put, warmer oceans make for more extreme weather including devastating storms.

9. Desertification

How global warming affects desertification is not entirely understood, yet it is clear that an elevation in atmospheric and ground-level temperatures is likely to aggravate soil and vegetation loss in already hot climes. An increase in evapotranspiration and the accompanying decrease in rainfall mean that already semi-arid and sub-humid areas found across the world would face a future barrenness that is almost irreversible. This would negatively affect biodiversity and have a major impact on local human cultures and wildlife.

 

10. Tsunamis

Although global warming does not directly influence the formation of tsunamis, they can be generated by events that are brought about by an amplification of the planet’s temperature. One example is the melting of ice sheets. Being extremely heavy, massive glaciers apply a considerable amount of pressure to the Earth’s surface underneath them. This anchorage decreases as the glaciers diminish, resulting in a ‘freeing up’ of tectonic masses that can lead to massive earthquakes and significant volcanic activity, both of which are capable of creating deadly tsunamis.
