Global temperature data shows fluctuations in the atmosphere and oceans. These temperatures, and the impacts of them, can impact many natural processes, such as agriculture, and can cause illness and death in people. Millions of people have been affected by extreme heatwaves, which has threatened their ecosystems. Certain regions are more affected by climate change than others.
Since 1981, the global average temperature has increased by nearly 2 degrees Fahrenheit. It has also risen at an average rate of 0.18 degrees Celsius per decade. This is far beyond the long-term trend of warming. This is more than twice the long-term trend.
The current rate for warming is much higher than that of the 1980s- 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 led to an increase in the intensity of tropical storms that are expected to have a significant impact on low-latitude areas.
As of January 2020 the global average surface temp is just 0.8 degree Celsius above the preindustrial level. A number of subregions are already above 1.5°C. 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. Some of these years (e.g. 2021) are projected to be amongst history's warmest.
Although there have been some exceptions, most of the Earth's surface experienced warmer temperatures than average in the first nine month of 2015. Most countries experienced temperatures above average. Some areas had record-breaking highs. Other regions such as the South American States and parts South America were warmer than average in recorded history.
Since the late 1970s the United States has warmed more quickly than the global average. This trend has slowed in recent years. According to the National Oceanic and Atmospheric Administration the average global temperature increased by around 0.17 degrees Celsius every decade. This rate is slightly higher than that of the contiguous 48.
Climate change deniers claim there is no reason to be concerned about global temperatures as the temperature has remained relatively stable for several decades. Scientists say that climate change is directly linked to catastrophic weather events. In reality, global surface temperatures have increased faster than they have decreased.
The Goddard Institute for Space Studies reported that the global average land and ocean temperature was 1.2 degrees Celsius higher than the 1850-1900 average in 2010. It is expected to rise to 1.1 to 1.15 degrees Celsius over the pre-industrial average by 2022. If the current rate of rise continues, we will reach 4°C by the end century. This could lead to unprecedented heat waves or severe drought in many places.
FAQ
What is the potential impact of land-use change and deforestation upon climate change?
The climate can be directly affected by deforestation and changes in land use. Carbon dioxide, which is the most important greenhouse gas on Earth, can't be absorbed by trees if they are removed or burned. Therefore, when trees are cleared by deforestation or burned for agricultural purposes, less carbon dioxide is removed from the atmosphere.
However, land use changes can increase greenhouse gas emissions. For example, when forests are replaced with agricultural lands for livestock production, fertilizer, and pesticide use may increase emissions of nitrous oxide and methane. In addition, clearing can increase exposure to soils that contain large amounts of stored carbon; when these soils are turned over or disturbed by farming activities, they release additional carbon dioxide into the atmosphere.
The impacts of deforestation and land-use change extend beyond just increased greenhouse gas emissions; it can also have an impact on regional air quality. As an example, deforestation smoke has been shown to reduce visibility and cause respiratory illnesses such asthma and other conditions. These changes in air quality can have a cumulative affect on global climate change. The increase in temperatures is due to more sun hitting the Earth's surfaces.
In conclusion, deforestation and land-use change have resulted in a significant contribution to increased levels of global greenhouse gas emissions and have had negative impacts on local air quality that further contribute to climate change. If serious efforts to combat climate change are to occur, it should be a top priority to reduce these practices.
What are the impacts of climate change on developing countries and communities?
Developing countries and communities are particularly vulnerable to the effects of climate change due to limited access to resources, healthcare systems, and technology. Climate change can increase the pressure on already limited resources. Floods and droughts can also cause damage to 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 like hurricanes or heatwaves can also cause destruction to infrastructure, causing further economic inequality.
The long-term impacts of climate change include resource scarcity, poverty, increased health risks, and an increase of vector-borne diseases, such as malaria and dengue fever. There will also be an increased risk of flooding from rising sea levels, combined with extreme weather events. This puts lives at risk in coastal locations where many people lack the necessary infrastructure and emergency services to evacuate. These risks can be mitigated by reducing greenhouse gas emissions. However, other measures may be required such as better management of freshwater resources or easier access to healthcare facilities that aid in the prevention of diseases like malaria.
How can the world move towards a more sustainable future in light of the challenges posed by climate change?
Sustainability is the ability not only to meet current needs but also to ensure that future generations can meet their needs. An urgent need exists to act to eliminate our dependency on finite natural resources and to shift towards a more sustainable method of using them.
To move towards a more sustainable future, it is important for us to reconsider our current models of consumption and production, as well as our dependence on natural resources such as fossil fuels. We must search for new technologies, renewable energies, and systems to reduce harmful emissions, while still meeting our daily requirements.
Additionally, sustainability must be approached from a holistic perspective. This means that all aspects are considered, including the materials used, waste management strategies and reuse strategies, as well energy usage in transportation and industry. There are many solutions that can be found, such as the utilization of renewable energy, like solar, winds, and hydropower, better waste management, higher efficiency in agriculture, improved transportation networks, green building regulations and sustainable urban planning.
Furthermore, behavioral changes are required amongst individuals across different sectors throughout society for us to accomplish this goal. Education programs are necessary to help people understand the climate change issues and how they can make a positive contribution towards a more sustainable world.
Only through cooperation between citizens, business leaders, and governments will we ever be able make substantial progress towards creating a sustainable world for future generations.
What are the causes and consequences of climate change?
Climate change is a global phenomenon that has been driven by an increase in human-generated greenhouse gases emitted into our atmosphere, primarily due to fossil fuel burning for electricity and transportation. These greenhouse gases trap more heat from the sun, which causes global warming.
Climate change can also be caused by population growth, land clearing, destruction of ecosystems and energy consumption, over-grazing, and deforestation. This further reduces the number of naturally occurring carbon sinks that absorb CO2 from the atmosphere. Climate change may also be caused by natural factors such as changes to solar radiation.
This combination of human activities results in Earth exceeding its ability to balance its energy budget. The result is an average global increase of 1° Celsius since pre-industrial days. Glaciers melt faster than they form and sea levels rise as oceans absorb most of this heat energy. Other damaging consequences include water scarcity and droughts or extreme weather events like floods and hurricanes caused by frequent heavy precipitation on saturated soils.
To protect ourselves from further damage, it is essential for us to reduce our carbon footprint and start curbing our emissions now so that we have a fighting chance against the already significant impacts 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. You can also restore some balance in these delicate cycles of the planets that sustain us, such as reforestation.
