Global temperature data illustrates fluctuations in both the global atmosphere and the oceans. 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. Extreme heatwaves are threatening ecosystems and causing millions of people to die. Certain regions are experiencing greater warming 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 significantly more than the long-term trend for warming. In fact, it is double the long-term trend.
The current rate of warming is greater than the previous two warmest decades, which were the 1980s and 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 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 temperature is now nearly 0.8 degrees Celsius above the pre-industrial average. Many regions are already at 1.5 degrees Celsius. This level has not been reached in a decade. During the past three decades, global warming has exceeded 0.2 degrees Celsius per decade, a rapid rate that will likely increase in the coming years.
A recent report by the World Meteorological Organization (WMO) states that there is a 40% chance the global average temperature will rise above 1.5degC within the next five year. Some of these years (e.g. 2021) are projected to be amongst history's warmest.
While there are some regions that have seen greater warming than others, the vast majority of the Earth’s surface was warmer in 2015's first nine months. Many countries' temperatures were higher than average. Some regions had records-breaking highs. Other regions, like the southern United States of America and parts South America were among the most hot in recorded history.
The United States has warmed faster than the global average since the late 1970s. However, this trend has been slowing 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 deniers claim there is no reason to be concerned about global temperatures as the temperature has remained relatively stable for several 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 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 can we do to limit or mitigate the impacts of climate change?
There are various measures that can be taken to reduce and mitigate the effects of climate change. These include reducing greenhouse emissions by using greener energy sources and better energy practices. It's important that people are educated about climate change. This encourages them to take responsibility for their actions.
What role do greenhouse gases play in climate change?
Greenhouse gases are a key factor in climate change. They act like an invisible blanket surrounding the Earth, trapping the infrared radiation that warms it and keeping it from getting too hot. Without them, the planet would be much colder than it is today.
Human activity can cause greenhouse gases, such as the burning of fossil fuels and other industries that emit emissions. These activities increase the heat that is trapped in the atmosphere. This leads to higher temperatures and more extreme weather events.
The most abundant greenhouse gas is carbon dioxide (CO2), which is released when burning fossil fuels such as coal, oil, and gas. Major contributors to climate disruption are methane (CH4) as well as nitrous dioxide (N2O) and fluorinated gases (F-gases).
Since preindustrial times, the concentration of greenhouse gases has risen significantly due to human activity. Global warming has resulted in an increase of temperatures around the world and in our oceans. It is also causing major changes such as stronger storms and more droughts, melting of glaciers, rising sea levels, and increased flooding.
To avoid more damage from climate changes, humans must reduce their emissions by switching away from fossil energy to increase their use of renewable energy like solar and wind power. There are also ways to reduce CO2 emissions, such as by planting trees and using agricultural techniques that absorb more of the gas. These activities will lower the atmospheric concentrations of greenhouse gasses and make the Earth a more healthy place for all life.
What are the current international efforts to combat climate change?
The international effort to tackle climate change has reached a new level of unity and momentum. Countries all over the world are now working together to reduce emissions, improve resilience against impacts, as well as invest in renewable energy sources.
The Paris Agreement has been a catalyst for global action. Individual countries can set voluntary targets for reducing their carbon emissions by using the framework provided by the Paris Agreement. The UN Framework Convention on Climate Change, (UNFCCC), provides political guidance and pilots new initiatives like carbon market mechanisms.
Other regions are seeing progress. The European Green Deal is a comprehensive legislation package that seeks to create a European economy with sustainability as its core. Countries on the African continent also have committed to The African Renewable Energy Initiative, which aims increase Africa's participation in global renewable energy production.
Apart from policy changes, action is visible across sectors and industry. Cities are actively transitioning to sustainable public transport systems. Society at large is adopting more sustainable lifestyles. Companies have been innovating technologies to lower emissions. Investors are switching away from fossil fuels to invest in renewables.
The OECD committee has adopted common standards to report national actions on climate change by rich countries. This is known as the 2021 Guidelines.
All these efforts are a sign of the unprecedented importance given to climate action. For any chance of reaching the climate goals set forth by science and international law, government, civil society, & private sector actors must build upon this momentum.
What are the environmental and social effects of climate changes?
Climate Change can have broad impacts on society as well as the environment. Climate change can have many effects on the environment. These changes can have devastating effects on human populations. They may lead to increased instability in communities and intensifying poverty as well as insect-borne diseases.
Already, climate change is having an enormous impact on the environment as well as societies around the globe. Global temperatures are expected to continue to rise and this will only get worse in the future.
The most significant effect of climate change globally is the rise in ocean levels caused by melting ice caps. This results in coastal erosion and increased flooding risks for coastal communities. Also, saltwater intrusion occurs, which negatively affects freshwater supplies in coastal areas in many countries.
Due to climate change, extreme weather phenomena such as heatwaves/droughts frequently occur across many countries in the world. These events cause massive destruction to homes, businesses, and sometimes even wipe out entire towns. In addition, intense storms create further risks related to flooding or landslides that increase damages to infrastructure such as roads and railways.
Also, wildfires due to climate change are occurring more often than ever. These fires can cause severe damage to habitats and the lives of people living close by.
Many people are forced to flee their homes due to drastic changes in their living conditions.
The increase in aridity causes dust storms to become more frequent, which makes people suffering from asthma and other respiratory ailments such as asthma even more vulnerable. Pest infestations will increase due to higher temperatures - a phenomenon called the 'greenhouse bug'. This can further impact global food insecurity as fewer crops are available with poorer nutritional qualities, potentially creating additional hardships for marginalized populations that otherwise would be barely able to make ends meet.

How To
How to Support Climate-Friendly Policies and Companies
Individuals have many options to support climate-friendly policies. This can include speaking out against non-climate-friendly businesses or politicians, voting for pro-environment candidates, writing letters or emails of encouragement to those who are already taking positive action towards the environment, and signing petitions in favor of policies that encourage and support climate-friendliness. Individuals can also take immediate steps to make a difference by switching to providers with a better record in the environment or choosing sustainable products instead of those with higher carbon omissions.
A key step to supporting climate-friendly policies is reducing one's carbon footprint. This could be done by changing everyday habits such as not plugging appliances or turning off lights, using public transportation, carpooling or using other means to get around, and using eco-friendly household items such as biodegradable cleaning materials and composting kitchen leftovers.
Investors who are keen to support climate-friendly policies will want to find companies that produce lower carbon emissions before investing. Investors who are interested in supporting climate friendly policies should research companies that emit less carbon than they own. They should also review their portfolios frequently to make sure they comply with the sustainability standards set by them. Green bond investors will want to ensure their investments do not fund any activity that releases more greenhouse gases into the atmosphere than it takes away. Investors should consider any opportunities that could allow funds to be used for green business activities. These include renewable energy alternatives as a way to promote sustainability and community-building projects using green technologies.
