Causes and Effects of Climate Change 

When reading articles about climate change, you may be surprised to learn that 90% of the heat from greenhouse gases is absorbed by the Ocean. As a result, sea levels are rising, and heat waves and droughts are becoming more common. In fact, these conditions are already beginning to cause severe health problems. The United Nations family is at the forefront of the effort to save our planet. Its 1992 Earth Summit produced the United Nations Framework Convention on Climate Change, or UNFCCC. This treaty has been signed by 197 nations and has almost universal membership.

Ocean has absorbed 90 percent of heat trapped by greenhouse gases

The ocean has absorbed 90 percent of the heat trapped by greenhouse gases and is an important factor in a stable climate. Extreme temperatures are already a reality in some hotspots and are damaging ecosystems and wildlife. Scientists are now examining the temperature changes of the ocean’s surface over the past 150 years, and the results show that the ocean is warming more rapidly than it was in the past.

Sea level is rising

The effects of climate change have led to rising sea levels in many parts of the world. As the Earth’s temperatures increase, ice sheets and glaciers will melt, raising the sea level. This will raise the sea level globally, but it will also affect individual regions. In some areas, the rate of rise will be higher than the average.

About half of the rise in sea level is due to ocean warming, a process known as thermal expansion. The other half is from the melting of thousands of small glaciers. Although these glaciers have contributed little to sea level changes since the 1800s, they are expected to melt faster in the future.

Heat waves are becoming more frequent

Climate change has a direct impact on heat waves, and the occurrence of such weather conditions has increased by 10 times in some regions of the world. A recent study by the U.K. Met Office found that a heat wave this summer was 10 times more likely than it would have been in pre-industrial times, due to human-caused climate change.

Heat waves are increasing in frequency and duration. Since the mid-twentieth century, they have become longer and more intense. Climate change is causing the climate of the planet to warm faster than ever before, and this is expected to increase the frequency and duration of heat waves. The United States is on track to experience an increase in heat waves of 70 percent by the end of the century if current greenhouse gas emissions continue. By then, heat waves are expected to affect nearly a third of the population, making them a major health threat.

Droughts are becoming more frequent

Climate change is causing more droughts and hotter weather overall, which is bad news for people who live in dry regions. Since late 2020, the United States has been experiencing unusually hot weather, which increases the risk of wildfires and heat-induced medical emergencies. Water levels in Lake Mead have dropped to historic lows. In addition, scientists have found human remains from forty to fifty years ago on the shores of the lake. As a result of these extreme weather conditions, scientists are beginning to suspect that droughts are becoming more frequent and severe due to climate change.

This conclusion comes from a study that used computer models and long-term observations to estimate the frequency and duration of droughts. Although the Intergovernmental Panel on Climate Change concluded that there is only a low degree of confidence in these studies, recent advances in drought detection and attribution have raised the likelihood of climate change affecting future droughts.

Coral reefs are disappearing

Coral reefs are a vital part of the ocean’s biodiversity. They provide homes for countless species and food. But as the climate changes, their plight is getting worse. Corals are dying at an alarming rate and scientists blame global warming for the problem. In the past 20 years, corals have suffered significant damage from heat-induced bleaching events. In addition, ocean heat waves are becoming more intense and frequent.

While it’s a difficult task to predict which coral species will survive in the future, there are strategies to ensure the long-term survival of corals. Reef managers can work to maintain conditions in local reef tracts that will allow corals to grow and thrive. They can also prioritize the creation of refugia, which provide a better environment for corals to thrive. However, finding such places is challenging. Climate projections can provide insight into how ocean temperatures are expected to change over time.

Human activity is driving climate change

Human activity is changing the climate system through the emission of greenhouse gases. These gases trap infrared heat and amplify the Earth’s natural greenhouse effect. This is the primary cause of recent global climate change. As a result, the Earth’s temperature has increased dramatically. Scientists have shown that human activity is the primary cause of this increase.

The most common greenhouse gas is carbon dioxide, which accounts for about 80 percent of human-induced climate change. It is released during the burning of fossil fuels, cement, oil, and gas. CO2 concentrations in the atmosphere have risen dramatically in the past 150 years. In the pre-industrial era, the concentration was around 280 parts per million. At present, the concentration of CO2 is estimated to be at its highest level in over 800,000 years.
