September Volume 25 Number 3. Many people believe that human-caused emissions of greenhouse gases will lead to higher temperatures and increased precipitation during the 21st century. Similarly, it is thought that these changes may have an impact on economic well-being.

Is There Any Upside to Global Warming?

The Pros and the Cons Our current climate crisis poses an existential threat unlike any that our species has experienced before. Emerging evidence suggests that the rapid increase in global average temperature will wreak havoc on not only our climate system, but also our day-to-day lives. In , global average temperature was 0. While we are already seeing the effects of a changing climate, scientists warn of significantly worsening impacts if warming is not kept below 1.

These severe impacts can include substantial land and sea ice loss, ocean acidification, changes in ocean circulation, and shifts in weather patterns which ultimately lead to food and water shortages along with economic and social unrest. There are also ways in which society may benefit from a warming climate. Reduced sea ice will open more passageways for ships and will allow the poles to be more accessible. A warmer climate may grant certain areas, especially northern latitudes, longer and earlier growing seasons.

Warmer winters mean less cold-induced deaths. Increased carbon dioxide levels may help vegetation to flourish for a greener world. Unfortunately, though, many of these benefits are short-term and are greatly overshadowed by the negative impacts that climate change brings. Ice is an important part of the global climate system because it reflects a large amount of solar radiation while also moderating global sea level. As ice melts, the less reflective ocean surface is exposed and instead of radiation being reflected, it is absorbed and causes more ice melt.

This is called a positive feedback system , which is what makes polar regions so sensitive to climate change. High northern latitudes are experiencing rapid warming due to polar amplification causing land and sea ice to melt at an increasing rate.

If warming exceeds 1. In Antarctica, ice melt varies greatly with net ice loss in some regions and net ice gain in others.

The WAIS has been seeing a rapid decrease in mass with a loss of up to Gigatons that is billion metric tons per year. Other ice formations such as snow cover and frozen soil called permafrost have also been melting at staggering rates.

From to , June snow cover in the Northern Hemisphere has decreased at a rate of In response to this, permafrost layers have warmed and thinned. Substantial loss in both land and sea ice can result in changes in weather, ocean thermohaline circulation, and sea level rise due to reduced solar radiation reflection and more water being added to the oceans. Land ice formation and melt lead to a rise or drop in sea level.

Sea level is also dependent on thermal expansion , the process of water taking up more space as its temperature increases. About three million years ago, when carbon levels were similar to what they are presently and there was less ice coverage, global average sea level was roughly 80 feet higher than what we see today.

With atmospheric carbon levels continuing to rise, global average temperature increasing, and consistent ice melt, climate scientists predict we will experience considerable sea level rise in the future. In fact, we already are. Climate models predict that the rate of sea level rise will increase to 16 millimeters per year by but will not be a uniform global event. The atmosphere and ocean are constantly exchanging properties such as temperature, water, and even gases.

Thus, as we put more carbon dioxide into the atmosphere, we are also putting more carbon dioxide into the ocean. This exchange of carbon is essential to both parties but when the ocean receives too much carbon, a process called ocean acidification takes place through the chemical process shown in Figure 1.

A more acidic ocean would be a lethal environment to most marine species which, in turn, will greatly impact humans, especially those who depend on our oceans for food.

As our present-day climate rapidly changes, a disruption in ocean circulation is also becoming an area of great concern. Thousands of years ago during times of abrupt climate change such as the Younger Dryas, it is believed that oceanic thermohaline circulation was slowed or halted thus altering both oceanic and atmospheric behaviors.

The main purpose of ocean circulation is to transport heat, water, and nutrients between the equator and poles. A cessation in this can cause numerous unwanted effects such as changes in marine ecosystems, large-scale convection, air-sea interactions, and wind patterns as the climate system tries to compensate for the loss of vital transport. Figure 1 illustrates the process of ocean acidification. Climate change not only affects temperatures, it also affects cloud formation, tropical cyclone development, and everything in between.

Civilization has long depended on precipitation events for water and agriculture. Patterns in these events were fairly predictable during a steady climate but a changing climate ushers in much variability which may lead to long-term droughts or floods. If warming reaches 1. Relatively dry regions such as the American Midwest are expected to face more frequent and intense droughts. Monsoon systems are likely to impact larger regions and intensify while precipitation related to El Nino Southern Oscillation is expected to increase.

Since , the North Atlantic has seen surges in tropical cyclone intensity and climate scientists predict that there will likely be more frequent and intense storms in the future. It is important to note that although climate models suggest these shifts in weather events, scientists believe these predictions are subject to change, but are still likely to happen, due to the numerous other factors that affect the development of meteorological events.

As discussed later, these changes in weather events will greatly impact water and food resources. One particularly extreme and, frankly, frightening topic that vastly outweighs any possible beneficial impacts is what climate scientists call tipping points.

In the climate system, a variable will change so much due to the warming climate that it will reach a point, its tipping point, where it is in a completely new state. Climate scientists believe that reaching tipping points in ice melt, ocean circulation, rainforest deforestation, and coral reef bleaching may push the climate system as a whole to a new state. In addition, tipping points do not exist in isolation. They are all interconnected, meaning that reaching one tipping point can trigger another one which, in turn, triggers yet another one.

In , roughly million people were malnourished. With much of the world already struggling to access clean water and food, it comes as no surprise that climate scientists are predicting significant losses in crop yield and clean water, due to climate change-induced droughts or floods, along with degradation of human health as a result of the warming climate.

Concerns of other health risks such as diseases, air quality-related mortality, and temperature-related mortality are also being raised. The elderly, children, low-income families, and those with pre-existing conditions are among the populations with greatest climate change-induced health risk.

Higher temperatures and degrading air quality will allow for increasing cases of diseases such as malaria, respiratory illnesses, and heat exhaustion. Food and water scarcity can lead to higher prices and disputes over access to these necessities; therefore, nations experiencing low food production and poor water quality with an unhealthy population will inevitably experience severe economic distress and social unrest.

The changing climate is expected to send up to 16 million people below the poverty line and possibly displace millions from their homelands. A common climate myth states that climate change may be beneficial. In this case, the myth focuses solely on the few positive impacts of a warming climate which diverts attention away from the mounting evidence that a rapidly warming climate will wreak havoc on all aspects of society.

Scientific research continues to prove that the negative impacts of climate change far outweigh any positive impacts. Our modern-day climate crisis has ushered in a host of problems for society to solve. If reached, a warming of 1. Consequently, much of society will be left without food, fresh water, and shelter.

But, if we listen to the science, we will have within our power the ability to take action to save not only ourselves, but also our planet.

Internationally, scientific information about climate change is periodically assessed by the Intergovernmental Panel on Climate Change IPCC , most recently in Much has been learned, and this knowledge base is continuously being updated and expanded with new research results.

Climate Science Glossary

Although there are many negative effects of climate change, there are some advantages too. The Arctic, Antarctic, Siberia and other frozen regions of the Earth may experience more plant growth and milder climates. The next ice age may be prevented from occurring. Many scientists believe that the planet is due to enter the next ice age and enhanced global warming will prevent this.

Advantages of climate change o Prevents ice age Ice age is the period in which the temperature drops to an extent that life becomes extremely difficult on Earth. It is believed that there has been five ice ages till date with regular warmer intervals. The climate change we experience now is a result of global warming where the temperature of the planet is gradually increasing.

The United Nations has been studying climate change and working to combat its effects since the first Earth Summit in We've heard the dire warnings—even if we have yet to heed them—but could there possibly be any advantages to climate change, and if so, could these upsides possibly outweigh the downsides? The short answer is no. Here's why. The so-called advantages of climate are out there—if you're really looking but do they compensate for the disruption and destruction wrought by the disadvantages? Again, the answer is no but for die-hard fans of the global warming trend, advantages might include the following suspect scenarios:.
