Global temperature data shows that there are fluctuations in the earth's atmosphere and oceans. These temperature changes and their consequences can have adverse effects on many natural processes including agriculture. They can also lead to sickness and death. The increasing frequency of extreme heatwaves has led to millions of deaths and endangered ecosystems. Some regions are more vulnerable to climate change than others.
Since the Industrial Revolution, the global mean temperature has risen by about 2 degrees Fahrenheit. The rate has been increasing at 0.18 degrees Celsius every decade since 1981. This is far more than the long term trend of warming. This is more than twice the long-term trend.
The current rate at which the world is warming is faster than in the 1980s or 1990s. This change in temperatures has had a major impact on a wide range of areas, from areas that are drier to higher-latitude regions. It has also impacted the intensity and sea-level rise of tropical cyclones.
As of January, 2020, the global average surface temperature is now nearly 0.8 degrees Celsius above the pre-industrial average. Many regions are already at 1.5 degrees Celsius. That level has not been seen for a decade. 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 a recent report from the World Meteorological Organization (WMO), there is a 40% chance that the global mean temperature will exceed 1.5degC in one of the next five years. Some of these years, like 2021, are expected to be amongst the warmest ever recorded.
Although there have been some exceptions, most of the Earth's surface experienced warmer temperatures than average in the first nine month of 2015. According to most estimates, temperatures in most countries were above average. There have also been records highs in some areas. Other areas, including the south of the United States and parts South America, were some of the most warm in recorded history.
Since the late 1970s the United States has warmed more quickly than the global average. 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 claim there is no reason to be concerned about global temperatures as the temperature has remained relatively stable for several decades. In truth, the global surface temperature has increased more rapidly than it has decreased, and scientists say that there is a direct correlation between climate change and catastrophic weather events.
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 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 do climate change and global warming impact agriculture and food security?
Climate change and global warming have a direct impact on agriculture and food security. Climate change can alter rainfall patterns, temperatures, soil moisture levels and extreme weather. This can lead to disruptions in farming activities, lower crop yields, and loss of agricultural biodiversity. Warmer temperatures could lead to the growth of pests or diseases, which can have a negative impact on crops. This can increase food production costs, as well as cause hunger and other nutritional problems worldwide.
Rising sea levels present a new threat. They can inundate agricultural land in many coastal locations, leading to increased salinity in wetlands where important crops grow. Changes in climate also have an impact on livestock production. In summer, high temperatures can lower fertility rates in animals like sheep and cattle. This can result in lower milk yields, which can worsen food insecurity.
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 involves promoting sustainable methods such as crop rotation techniques or genetic diversity through the conservation of native seed varieties, which help protect against negative impacts from extreme weather conditions or other environmental stressors caused by 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.
Farmers around the globe must adopt technology that is more sensitive to climate changes to ensure food security in a changing environment. It is essential to make improvements in existing infrastructure so that appropriate actions may be taken when crucial crop thresholds are reached. This includes the introduction of stable irrigation networks with adequate access waters at times when there is less availability due to warmer temperatures or heavy downpours, which can wash away important access water resources. 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 is the contribution of human activity to climate change?
Human activity is one of the major factors contributing to climate change. According to the Intergovernmental Panel on Climate Changes (IPCC), more than 70% global warming has been caused by humans since the middle of the 20th century.
Burning fossil Fuels: The atmosphere is effected by the combustion of fossil fuels like coal, oil and gas. This adds to already existing levels of atmospheric CO2, which act as a "greenhouse gas" by trapping heat from the sun in Earth's atmosphere and increasing temperatures even further. This results in higher ocean levels because Arctic ice mellows and causes weather patterns to change around the world, which can lead to severe storms, droughts or floods. These could impact food production and pose a threat to human health.
Deforestation: Trees that sequester atmospheric CO2 in their trunks during photosynthesis are destroyed by deforestation. Deforestation also raises albedo (the amount of reflected solar radiation that is returned into space) and reduces solar heat absorption by earth's surface, thereby promoting global warming. The deforestation of forests can also affect the local air quality, which is directly linked to respiratory problems.
Farming: Animal agriculture accounts for between 14%-18% worldwide's total anthropogenic greenhouse gas emissions. Large amounts of methane gas are released by animal waste due to its richness in methane bacteria. Eating less or none of these products can reduce global warming.
In conclusion, human activity has been drastically impacting our environment for centuries now, but with rapid advances made in technology such as renewable energy sources availability we have started turning our heads towards the future leaving behind carbon-emitting heavy industries results will soon start speaking themselves clearly when we leverage on technology through green innovation paving away toward eco-friendly efforts combatting climate change efficiently keeping everyone safe under prosperous nature purview.
How will climate change impact the world's oceans?
What are the effects of climate change on oceans and marine life around the globe?
Since its inception, climate change has had a significant impact on the oceans and marine life of the world. Constant oceanic warming due to the depleted ozone layer causes drastic disruptions in marine ecosystems resulting in a decrease in species and coral bleaching.
Climate change is also responsible for unpredictable weather patterns and stronger storms, which can lead to dangerously high sea levels. Additionally, temperature changes may cause water systems to lose oxygen. This can result in "dead areas" in which abundant marine life is reduced.
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. The increase in ocean stresses accelerates the already high rates of extinction worldwide. This can lead to a severe imbalance among predators and prey, which could ultimately lead to complete 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. The effects of climate change continue to impact the lives of entire species on this planet.

How To
How to Reduce Your Carbon Footprint & Fight Climate Change
There are many actions you can take in order to reduce your carbon emissions and fight climate change. First, you can reduce your energy consumption by purchasing energy-efficient appliances, lighting and insulation. It is possible to save energy by not using electronics, taking public transit, walking or driving and setting the thermostat lower in the winter and the summer.
Second, recycle as much material as possible. Compost food scraps rather than throwing them away. This will ensure that they don't end-up in landfills which release methane gas into our atmosphere. Third, plants trees around your house for shade and natural cooling. The air absorbs carbon dioxide through the vegetation. Additionally, look into purchasing products with minimal packaging.
In addition to reducing your own personal emissions, you can also support organizations that focus on reducing global emissions such as Emissions Reduction Alberta; Climate Change Solutions; The Pembina Institute or The Nature Conservancy Canada work towards lowering emissions through clean energy investments and international initiatives like ICLEI - Local Governments for Sustainability's urban sustainability strategies program.
Making small changes in our daily lives can help us all fight climate change together.
