Global temperature data shows variations in the oceans and atmosphere. These temperature fluctuations and their impacts can have a significant impact on many natural processes such as agriculture and can lead to illness and death. The increasing frequency of extreme heatwaves has led to millions of deaths and endangered ecosystems. Certain regions are experiencing greater warming than others.
Since 1981, the average global temperature has risen about 0.18 degree Celsius per decade. This is far beyond the long-term trend of warming. It is actually twice the long-term trend.
The current rate of warming is greater than the previous two warmest decades, which were the 1980s and 1990s. This warming has had an enormous impact on many different areas, from high-latitude and drier places to warmer areas. It has also increased the intensity and potential impact of tropical cyclones.
The global average surface temperatures are now almost 0.8 degrees Celsius warmer than the preindustrial average as of January 2020. A number of subregions are already above 1.5°C. This level has not existed in the past ten years. Global warming has risen at an alarming rate of 0.2 degrees Celsius every decade over the last 30 years.
According to a report from the World Meteorological Organization, 40% of global average temperatures will reach 1.5 degrees Celsius in the next five-years. Some of these years (e.g. 2021) are projected to be amongst history's warmest.
While a few regions have experienced more warming than others, the majority of the Earth's surface was warmer than normal in the first nine months of 2015. Temperatures in most countries are estimated to have been above average, with some areas having record high temperatures. Other regions, such the southern United States, and parts of South America, were amongst the warmest ever recorded.
Since the 1970s, the United States's temperature has been rising at a faster pace than the global average. This trend has slowed in recent years. The National Oceanic and Atmospheric Administration reports a slight increase in global temperatures of 0.17 degrees Celsius per ten years, which is slightly slower than the average rise in the contiguous 48.
Climate change denier argue that global temperature is not an issue because the temperatures have remained fairly stable over the past few decades. The truth is that the global surface temperature has increased faster than it has fallen, and scientists believe there is a direct link between climate change, extreme weather, and other factors.
According to the Goddard Institute for Space Studies, the average global land and ocean surface temperature was 1.2 degrees Celsius above the 1850-1900 average in 2010, and is expected to be 1.1 to 1.15 degrees Celsius above the pre-industrial average in 2022. If this rate of growth continues, it will lead to temperatures exceeding 4 degrees Celsius by the end of century. This would cause unprecedented heat waves and severe droughts in many areas.
FAQ
What does climate change mean for the oceans and marine life of the world?
What are the effects of climate change on oceans and marine life around the globe?
Since its inception, climate changes have had significant impacts on the oceans of the world and the marine life that surrounds them. The depletion of the ozone layer, which causes constant oceanic warming, has caused major disruptions to marine ecosystems. This has led to coral bleaching and a decline in species.
Climate change may also be responsible for extreme sea level rises and more unpredictable weather conditions, which can prove to be fatal to coastal areas. Temperature changes can also cause water levels to drop, causing "dead zones", areas where there is less marine life.
Climate change is also contributing to ocean acidification, caused by excess carbon dioxide released into the atmosphere that accumulates within the oceans. Ocean acidification alters the pH balance, which makes it impossible for some animals, like oysters, crabs, and clams to adapt.
The effects of higher temperatures on natural habitats can be altered by shifting their geographical locations or shrinking them all together. This could lead to certain species becoming uninhabitable. An increase in ocean stress can accelerate already high extinction rates of many species around the world, resulting in a severe imbalance between predators/prey that could eventually lead to total extinction.
The effects of climate change ripple throughout entire ecosystems influencing multiple species whether directly or indirectly through evaporation lowering water volumes or sharp temperature shifts jeopardizing any sustainable development for fisheries and other maritime activities. Global climate change continues to decimate entire species, changing future lives on earth and below the surface of the oceans.
How is extreme weather related to climate change
Global warming has directly affected extreme weather phenomena such as heatwaves. Atmospheric temperatures have increased due to global warming which has affected different weather phenomena on a global scale.
According to climate scientists the average frequency for extreme weather-related events has increased more than twofold since 1980. As sea temperatures rise, so do wind patterns. This has an impact on the normal distribution and strength of hurricanes and storms across different regions of the planet.
The 2015 El Nino event brought warm water toward South America. It caused alarmingly high temperatures and heavy rains, which led to flooding in Peru. These floods resulted in displacement of people and property destruction. Several places including Antarctica have recorded their highest-ever temperatures indicating a definite relation between global warming trends and the occurrence or frequency of extreme weather events around the world.
Another example of climate change at work is Hurricane Irma. It was a major storm that struck Florida in 2017, causing economic losses of $50 billion.
The Intergovernmental Panel on Climate Change concluded that humans are increasing the severity and frequency of climate change. This naturally leads to more severe, frequent, and intense natural catastrophes worldwide. It also provides strong evidence about human involvement in extreme weather events that occur at regular intervals around us all.
What are the effects of climate change on the environment and society?
Climate change has many impacts on society and the environment. Climate change can have many effects on the environment. These changes can have grave consequences for human population, increasing instability and inflicting insect-borne disease and poverty on a large scale, as well as altering migration patterns and destroying important habitats.
Already, climate changes are having wide-ranging and profound effects on the environment worldwide. As global temperatures rise, this trend is likely to intensify in the near term.
One of the most widespread effects of climate change is the rising ocean levels due to melting of ice caps. This results in coastal erosion and increased flooding risks for coastal communities. In many countries, saltwater intrusion can also occur, affecting freshwater supplies in the coastal areas.
As a result, extreme weather events such heatwaves or droughts are common in many countries. These events cause massive destruction to homes, businesses, and sometimes even wipe out entire towns. Additionally, severe storms pose additional risks due to flooding or landlides that can increase damage to infrastructure such roads and railways.
Climate change is also causing wildfires to become more frequent than ever before. This can have devastating effects on habitats as well as people living near them.
This drastic change in living conditions is often a result of displacement or even refugee situations. When people decide to leave their homes, either involuntarily or voluntarily, it can be because their town has become too dangerous or not habitable due the changed climate conditions.
Increased aridity also increases dust storms worldwide with unhealthy air pollution caused by these making it difficult for people who suffer from respiratory illnesses such as asthma especially vulnerable. Furthermore, pest infestations are predicted to rise in tandem with warmer temperatures. This phenomenon is known as the 'greenhousebug'. Global food insecurity will continue to grow as fewer crops have lower nutritional qualities. This could potentially lead to more hardships for people already struggling to make ends work.
What can be done to reduce or mitigate the effects of climate change?
There are many measures you can take to mitigate and reduce the impacts of climate change. These include reducing greenhouse gas emissions through better energy practices and using alternative sources of energy such as renewable resources, employing more efficient agricultural techniques, improving land management practices, enhancing air quality laws, protecting forests and wilderness habitats, protecting against extreme weather events such as floods and droughts, investing in sustainable transport systems, strengthening early warning systems for disasters, beginning a research program on the impact of climate change on biodiversity and ecosystems, investing in green technologies such as solar panels or wind turbines, encouraging sustainable consumption habits, implementing suitable environmental regulations across all sectors of society. It's also important to educate the public about climate change. This will encourage people to be responsible for their actions.
