Global temperature data illustrates fluctuations in both the global atmosphere and the oceans. These temperatures, and the impacts of them, can impact many natural processes, such as agriculture, and can cause illness and death in people. The increasing frequency of extreme heatwaves has led to millions of deaths and endangered ecosystems. Some regions experience more warming than others.
Since 1981, the average global temperature has risen about 0.18 degree Celsius per decade. This is far more than the long term trend of warming. It's actually double the long term trend.
The current rate is higher than those of the 1980s, 1990s, and 1990s. This increase in temperatures has had a large impact on a variety of areas, from drier areas to high-latitude regions. It has also increased intensity of tropical Cyclones, which will have an impact on low-latitude regions as well as sea level rise.
As of January 2020 the global average surface temp is just 0.8 degree Celsius above the preindustrial level. Some subregions already have temperatures above 1.5 degrees Celsius. This level has not existed in the past ten years. Global warming has increased at a rapid pace over the past 30 years, exceeding 0.2 degrees Celsius per year for the last three decades. This rate will continue to rise in the future.
According to the World Meteorological Organization's (WMO), 40% of global temperatures will rise to 1.5degC or more in the next five decades, according to a new report. A few of these years, such as 2021, are projected to be among the warmest in history.
Although there have been some exceptions, most of the Earth's surface experienced warmer temperatures than average in the first nine month of 2015. The average temperature in most countries was above average. However, some regions experienced record high temperatures. Other regions, such the southern United States, and parts of South America, were amongst the warmest ever recorded.
The United States has warmed at an even faster rate than the global mean since the late 70s. In recent years, however, this trend has slowed. According to the National Oceanic and Atmospheric Administration, the average global temperature has risen at an average rate of 0.17 degrees Celsius per decade. This is slightly less than the average increase in 48 contiguous states.
Climate change deniers argue that global temperature has not changed much over the last 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 (GIS), the global average ocean and land surface temperatures were 1.2 degrees Celsius warmer than the 1850-1900 standard in 2010 and are expected to rise to 1.1-1.15 degrees Celsius in 2022. If the current rate continues to rise, it could be that we exceed 4 degrees Celsius in the next century. This will cause extreme heat waves and drought in many regions.
FAQ
How can human activity impact climate change?
Climate change is caused primarily by human activity. In fact, according to the Intergovernmental Panel on Climate Change (IPCC), humans are responsible for more than 70% of all global warming since the mid-20th century.
Burning Fossil Fuels: Burning fossil fuels such as coal, oil, and gas releases carbon dioxide into the atmosphere. This creates more atmospheric CO2, which acts like a "greenhouse" gas, trapping heat and increasing temperatures. This can result in an increase in ocean levels due to Arctic ice melting. This creates unpredictable weather patterns that can disrupt food production and threaten human health.
Deforestation - Trees which store atmospheric carbon dioxide within their trunks, when they absorb it through photosynthesis, are removed by deforestation. The albedo is also increased by cutting down forests. It refers to the amount of solar radiation reflected back into space. As well decreases local air quality with deforestation being linked permanently with respiratory issues.
Farming: Each year, between 14% and 18% global anthropogenic greenhouse gases are released by the animal agriculture industry. Due to the high levels of methane bacteria in animal waste, methane gas is released into the atmosphere in large quantities. Changing your diet to less or no animal products can help reduce this contribution. Smog from ground-level ozone can harm our respiratory system and make our lives more hazardous.
Conclusion: Human activity has had a profound impact on the environment for centuries. However, technology has made it possible to leverage green innovation and make eco-friendly efforts to combat climate change. This will ensure that everyone is safe while prospering in nature.
What are the main causes of climate changes?
Climate change is a worldwide phenomenon caused by an increase of human-generated greenhouse gasses emitted into the atmosphere. This is mainly due to fossil fuel burning for power and transportation. These emissions lead to a greater amount of sun's energy being trapped in Earth’s atmosphere, which results in rising temperatures.
Other contributing factors to climate change are population growth, land clearance and destruction of ecosystems as well as deforestation, energy use, over-grazing and energy consumption. This reduces the amount of carbon sinks naturally found in the atmosphere that absorb CO2. Climate change can also come from natural forces, such as changes in solar energy.
These human activities together result in Earth experiencing an overloading of its energy budget. This has caused an average global rise of 1° Celsius over pre-industrial time. As the oceans absorb most heat energy, glaciers melt more quickly than they form. Water scarcity, droughts, or extreme weather events such hurricanes and floods can also have devastating consequences.
To prevent further damage, we must reduce our carbon footprint and cut our emissions as soon as possible. We can also take action now to mitigate the already severe effects of climate change. Reducing our dependence on fossil fuels for electricity production is crucial alongside investing in renewable sources - think wind turbines or solar panels - which do not emit any harmful pollutants into the environment. These delicate planetary cycles are also susceptible to other sustainable practices, like reforestation.
How can extreme weather events be related to climate changes?
Global warming has directly affected extreme weather phenomena such as heatwaves. Global warming has caused an increase in atmospheric temperatures. This has had an impact on different weather phenomena worldwide.
According to climate scientists in 1980, extreme weather-related natural disasters have increased by more than twice the rate. The sea level rises due to rising ocean temperatures and changing 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 pushed warm water toward South America resulting in rising temperatures at an alarming rate along with heavy rains that triggered floods in Peru and Bolivia resulting in the displacement of people and property damage. Many places, including Antarctica, have experienced their highest temperatures ever. This indicates a direct relationship between global warming trends as well as the frequency or occurrence of extreme weather events all over the globe.
Another example is Hurricane Irma in 2017. It caused $50 billion economic loss to Florida and other states, as well as Puerto Rico and Cuba. This is yet another proof that climate change is responsible.
Intergovernmental Panel on Climate Change (IPCC), concluded human activities are increasing climate change's severity. This in turn leads to more frequent and severe natural disasters across the globe. Therefore, strong evidence is available regarding our relationship with extreme weather events happening at frequent intervals all around us.
How do climate change and global warming impact agriculture and food security?
Global warming and climate change have an immediate impact on agriculture and food safety. The changing climate can impact rainfall patterns and temperatures as well as soil moisture levels. Extreme weather is also possible. This can disrupt farming activities, reduce crop yields and lead to losses of agricultural biodiversity. Warmer temperatures can cause crop diseases and pests to multiply. It can also affect the ranges that are suitable for agricultural production. In turn, this could increase the cost of food production and result in a greater incidence of hunger and poor nutrition worldwide.
Rising sea level poses a risk because they could flood agricultural land along many coasts, causing increased salinity to wetlands. Climate change can also impact livestock production. Warm summer temperatures can reduce the fertility of animals like cows, sheep, and goats. This can cause lower milk yields and increase food insecurity within communities.
The relationship between climate change and global warming is a complex one; however, efforts are being made to mitigate these results through adaptation strategies implemented by governments worldwide such as strategic investments in climate-smart agriculture (CSA). This includes promoting sustainable methods like crop rotation techniques and genetic diversity through conservation of native seed varieties. These help to protect against adverse impacts from extreme weather conditions and other environmental stressors due to the changing climate. In addition, CSA strategies call for reductions in greenhouse gas emissions through the use of renewable energy sources and the reduction of deforestation-related logging activities.
It is essential that farmers worldwide adopt technologies that are more responsive to changes in the environment when selecting the right crops to grow on specific parcels of land to ensure food security amid a rapidly changing environment. Existing infrastructure must be improved to allow for the appropriate action when necessary. This includes stabilizing irrigation networks that have adequate access to water during periods when there are less water sources due either to extreme downpours or warmer climates. For sustainable solutions to be created that will ensure the continued compliance with international dietary guidelines in our ever-changing climates, it is necessary to have a cohesive collaboration among all stakeholders. This includes government officials at international levels as well as NGOs located at local communities.
What happens to developing countries when they experience the climate change effects?
Because of their limited access and lack of technology and healthcare, the impact climate change has on developing countries and communities is particularly severe. Changes in temperature, precipitation, and sea levels increase pressure on already scarce resources, with floods and droughts wearing away at already fragile ecosystems. Rising temperatures can result in a reduction in crop yields. This will be disproportionately detrimental to poorer communities who are facing food insecurity. Extreme weather events such as hurricanes or heatwaves may cause damage to infrastructure and the displacement of people. This can further perpetuate economic inequality.
Long-term consequences of climate change include increased resource scarcity and poverty as well as health effects such as an increase in vector-borne diseases like malaria or dengue fever. In addition, there will be a higher risk of flooding due to rising sea levels coupled with extreme weather events putting lives at risk in coastal areas where populations often lack the adequate infrastructure or emergency services needed for evacuation. Building resilience against these risks necessarily involves mitigating greenhouse gas emissions but may require other measures such as improved management of freshwater resources and better access to health facilities which assists with prevention strategies for diseases like malaria.
What role do greenhouse gases play in climate change?
Greenhouse gases play a major role in climate change. They act as an invisible shield around the Earth and trap infrared radiation, warming the atmosphere. Without them, the Earth would be much colder today than it is today.
Greenhouse gases are generated through human activity, such as burning fossil fuels or other industries that produce emissions. As more heat enters the atmosphere from these activities, it leads to increased temperatures and extreme weather.
The most abundant greenhouse gas is carbon dioxide (CO2), which is released when burning fossil fuels such as coal, oil, and gas. Climate change is also caused by major greenhouse gases like methane (CH4) and nitrous oxides (N2O).
Due to human activities, the concentration of greenhouse gasses has increased dramatically since preindustrial time. Global warming has resulted in an increase of temperatures around the world and in our oceans. It's also causing changes like more severe storms and droughts as well as melting glaciers and rising sea level.
To reduce further damage caused by climate change, human beings need to decrease their greenhouse gas emissions. We can do this by shifting away from fossil fuels in favor of renewable energy sources like solar and wind power. We can also take measures such as reforestation or adopting agricultural methods that allow the soil to absorb more CO2 from the air. These activities will help lower atmospheric concentrations of greenhouse gases and create a healthier environment for all life on Earth.
