The Effects Of Climate Change On Humans

The Effects Of Climate Change On Humans – The effects of climate change are already being felt around the world. The Earth is warming, rainfall patterns are changing, and sea levels are rising. These changes can increase the risk of heat waves, floods, droughts and fires.

A changing climate affects crop growth and human health, while many people have to leave their homes. This puts some species at increased risk of extinction. The effects of climate change are real, and they are already happening.

The Effects Of Climate Change On Humans

The level of climate change we will see depends on how fast we cut emissions of dangerous greenhouse gases. Even if we stop all emissions today, we will not stop some changes. However, the faster we reduce emissions, the smaller the changes will be.

Mitigation And Adaptation

We know that greenhouse gases, aerosol emissions and land use affect our climate. Overall, human activity is warming our planet.

Learn more about these and other indicators of climate change on our Global Climate Dashboard and Extreme Dashboard.

In a recent report, the Intergovernmental Panel on Climate Change (IPCC) showed a difference between 1.5°C and 2°C of global warming. But unless we reduce emissions quickly, global temperatures will rise by more than 2 degrees Celsius. By the end of this century, temperatures could reach 4 degrees Celsius, possibly more.

Climate change will increase the risk of various problems around the world. Although developed countries produce the most greenhouse gas emissions, developing countries are predicted to see the most severe impacts. With fewer resources to adapt to these changes, the impact on people in developing countries is expected to be greater.

Since 1850, the average global temperature has increased by more than 1 degree Celsius. 2015, 2016, 2017, 2018, 2019 and 2020 were the hottest years on record. Statistics show us that the planet has been warming since the Industrial Revolution.

This plot shows global temperature change from 1850 to 2022, compared to an estimated 1850-1900 baseline average temperature.

A warm winter brings many other changes to our climate. As the Earth warms, heat waves become more likely. For the past few years, heat waves have been the world’s most dangerous climate.

Oceans absorb 90% of the excess heat produced by human impacts. However, when water is heated, it expands to take up more volume. Therefore, when the oceans warm, they expand, causing sea levels to rise. We also have excess water in the oceans from melting ice sheets and glaciers. Between 1901 and 2018, the global average sea level has risen by about 20 centimeters.

A Human Disease Indicator For The Effects Of Recent Global Climate Change

Some parts of the Earth, such as the North and South Poles, warm faster than other places. At the poles, glaciers and ice sheets reflect energy from the sun into space. Therefore, when there is less snow, less energy from the sun is reflected away. The area warms even faster, causing even more ice to melt.

The ice in the Arctic is melting rapidly. It is already 65% ​​thinner than in 1975. Late summer Arctic sea ice extent is currently the smallest in at least 1,000 years. If we don’t reduce emissions soon, we could see ice-free summers in the Arctic by the middle of this century.

When ice sheets and glaciers melt, fresh water flows into the ocean. As well as raising sea levels, fresh water also lowers the salinity (salinity) of the water, which can slow or alter ocean currents.

Oceans also absorb 25 percent of the carbon dioxide that humans release into the air. The oceans then become less alkaline, a process known as ‘ocean acidification’. Ocean acidification is bad because it can negatively affect marine organisms, such as corals and plankton, which are an important part of the food chain.

Climate Change And Human Behavior

**Marvel et al 2019 provides new evidence of increased aridity in some regions during specific periods since 1900 (with aerosols possibly masking the trend when it cannot be detected) and that it is linked to climate change.

Warmer air can hold more water, so the average rainfall around the world is increasing. In some places, rain is also intensifying. However, some areas receive less rain due to changes in wind patterns.

We are already feeling the effects of a changing climate. Sea level rise causes problems for people all over the world. Almost 4 in 10 people (39%) live within 100 kilometers of the coast and are at risk of flooding if sea levels continue to rise. Of these, 600 million live in the ‘low-lying coastal zone’, and 200 million in the coastal floodplain.

Even if we reduce emissions, sea levels will continue to rise until the year 2100 (see the Sea Level Dashboard for more on these projections). But, if we reduce emissions enough, we can slow the rate of growth. Many people will have to leave their homes, but the number will vary depending on how we act, by reducing global emissions and improving flood protection.

Report Details How To Reduce Impact Of Climate Change On Human Health

Flooding can also occur when heavy rainfall overwhelms drainage systems or buries river banks. In large concrete urban areas and cities, the impact is more severe because the water does not seep directly into the soil. Floods cause severe damage to buildings and transportation, which can be very expensive and difficult to restore.

As our climate’s temperature and rainfall patterns change, it may be difficult to grow enough food in some areas. The weather will change which crops can be grown in different regions. Some areas may be able to grow new crops, but many areas will experience reduced crop yields, especially in warmer countries.

Colder countries are likely to see higher yields because there will be a longer growing season and higher carbon dioxide concentrations. However, these effects will not last if the heating is continued for a long period of time. More extreme weather events can also disrupt access to food, affecting transport from farms to stores, which can affect vulnerable people.

As you can see, climate change has many effects, and they affect people around the world in different ways. The level of influence depends on the climate of the region and the wealth of the country. The effects of climate change are ‘stress-additive’, meaning they often make existing problems more acute.

What Is Climate Change?

Let’s look at heat waves, for example. We expect most areas to experience more intense heat waves. In countries that are already hot, human heat stress thresholds are often increased, which is dangerous.

For example, an increase in flooding is another risk. Countries that experience regular flooding, such as Bangladesh, are expected to see even more regular flooding, putting more communities at risk.

If our climate change continues, many parts of the world will become more difficult places to live. People have to leave their homes. Climate is only one of many factors that influence human migration, but it will play an increasing role in the future.

Climate change is causing warming across the UK. Britain’s ten warmest years on record have come since 2002. Heat waves, like the summer of 2018, are now 30 times more likely due to climate change.

UK winters are expected to be warm and wet on average, although cold or dry winters will still occur occasionally. Summers are likely to be hotter and drier, although hot summers are also possible. By 2050, the heat wave seen in 2018 is expected to occur every other year.

Heavy rain is also likely. Since 1998, Britain has seen six out of ten years on record. Winter storms were at least 40 percent more likely in 2015 because of climate change.

This tool is in collaboration with the BBC. It uses our climate forecasts and records to look at climate change in the UK.

Even if we reduce greenhouse gas emissions, sea levels around the UK will continue to rise beyond 2100. Parts of the UK will be at risk of flooding, with streets and coastal towns particularly at risk.

The Rising Impact Of Climate Change On Human Health

Agriculture in the UK will also be affected by climate change. Warmer weather and higher CO2 levels may make certain crops easier to grow, or allow us to grow new ones. However, with more drought expected, access to water may not be easy, making it difficult for farmers to plan the growing season. Some of the crops we grow today may not be suitable for high temperatures.

Floods, storms, and extreme heat can damage buildings, disrupt transportation, and affect health. Buildings and infrastructure need to be adapted to cope with new conditions. Businesses have to plan around the changing weather. To help the UK understand what climate change means for the nation, the UK Climate Change Risk Assessment is published every 5 years. Further details of projected future conditions for the UK are available in UK Climate Projections (UKCP18).
