What Will Climate Change Cause – Climate change is already having a visible impact on the world. The earth is warming, rainfall is changing and sea levels are rising. These changes can increase the risk of heat, floods, droughts and fires.
A changing climate affects crop growth and people’s health, and many people may have to leave their homes. This puts certain species at increased risk of extinction. The effects of climate change are real and already showing.

What Will Climate Change Cause
The rate of climate change we see depends on how quickly we reduce emissions of dangerous greenhouse gases. Even if we stop all feeds today, we cannot prevent some changes. But 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 climate change indicators on our Global Climate and Extremes 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 if we don’t cut emissions quickly, global warming is likely to exceed 2°C. By the end of this century, warming could potentially reach 4°C, perhaps 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 expected to experience most of the brunt. With fewer resources to adapt to these changes, the impact on people in developing countries is expected to be greater.
Fact Check: Scientific Consensus Humans Main Cause Of Climate Change
The average global temperature has risen by more than 1°C since 1850. 2015, 2016, 2017, 2018, 2019 and 2020 were the hottest years on record. Our numbers show that the planet has been warming since the Industrial Revolution.
This graph shows the change in global temperature from 1850 to 2022 compared to the projected baseline average temperature from 1850-1900.
Global warming is driving many other changes to our climate. As the planet warms, heat waves become more likely. In recent years, heat waves have been the deadliest global weather hazard.
The oceans absorb 90% of the extra heat generated by human influence. However, when water is heated, it expands to take up more volume. So when the oceans warm, they also expand, causing sea levels to rise. We also have additional water flowing into the ocean from melting glaciers and ice caps. Between 1901 and 2018, the average global sea level rose by about 20 centimeters.

Some parts of the planet, such as the North and South Poles, are warming faster than other places. At the poles, glaciers and ice caps reflect energy from the sun into space. So when there is less ice, less energy from the sun is reflected. The area then heats up even faster, causing even more ice to melt.
Arctic ice is melting fast. It is already 65% thinner than in 1975. The area of Arctic sea ice at the end of summer is currently the smallest in 1,000 years. If we don’t cut emissions soon, we could see ice-free summers in the Arctic by the middle of this century.
When glaciers and ice caps melt, fresh water flows into the sea. In addition to sea level rise, freshwater also reduces the salinity (salinity) of water, which can slow or change ocean currents.
The oceans also absorb about 25% of the carbon dioxide that humans release into the atmosphere. The oceans then become less alkaline, a process called “ocean acidification.” Ocean acidification is bad because it can have negative effects on marine organisms like corals and plankton, which are an important part of the food chain.
Facts That Prove The World Is In A Climate Emergency
** Marvel et al 2019 provides new evidence that drought has increased in some regions during certain periods since 1900 (with aerosols possibly masking the trend when it cannot be detected) and that this is linked to climate change .
Warmer air holds more water, so the amount of precipitation increases on average around the world. In some places, the precipitation is more intense. However, some areas saw less rain due to changes in the wind.
We are already feeling the effects of a changing climate. Rising sea levels are causing problems for people around 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. 600 million of these people live in the “low-lying coastal zone” and 200 million in the coastal floodplain.
Even if we cut emissions, sea levels will continue to rise until 2100 (see Sea Level Overview for more on these projections). However, if we reduce emissions enough, we can slow the rate of growth. Many people will have to leave their homes, but the numbers will vary depending on how we act to reduce global emissions and improve flood protection.
What Is The Cause Of Climate Change?
Flooding can also occur when heavy rains overwhelm sewer systems or breach river banks. In heavily concreted urban areas and cities, the effect is more pronounced because water cannot sink directly into the soil. Flooding causes severe damage to buildings and traffic, which can be very expensive and difficult to restore.
As our climate warms and rainfall changes, it may be harder to grow enough food in some areas. Climate will change which crops can grow in different regions. New crops may be grown in some places, but crop production will be reduced in many places, especially in warmer countries.
Cooler countries are likely to see higher yields because there will be a longer growing season and higher carbon dioxide concentrations. However, these effects may not be permanent if warming continues over the longer term. More extreme weather events could also disrupt access to food, affecting transport from farms to stores, which could affect vulnerable people.
As you can see, climate change has many impacts and affects people around the world in different ways. The level of influence depends on the climate of the area and the wealth of the country. The effects of climate change are “stress multipliers,” meaning they often exacerbate existing problems.
The Real Cause Of Climate Change. Or…how Our Emotions Will Drive Our…
Consider, for example, heat. We expect most regions to experience more intense heat. In countries that are already hot, human heat stress limits will be exceeded more often, which is dangerous.
As another example, another danger is the increase in flooding. Countries that experience regular flooding, such as Bangladesh, are expected to witness even more regular flooding that will threaten more communities.
If our climate continues to change, many parts of the world will become more difficult places to live. People may have to leave their homes. Climate is only one of many factors influencing human migration, but it will play an increasingly important role in the future.
Climate change is causing warming in the UK. All ten of the UK’s hottest years on record have occurred since 2002. Heat waves like the summer of 2018 are 30 times more likely due to climate change.
Play It Green
Winters in the UK are expected to be warmer and wetter on average, although there will still be occasional cold or dry winters. Summers are forecast to be warmer and more likely to be drier, although wetter summers are also possible. By 2050, heat waves like the one in 2018 are expected to occur every other year.
Heavier precipitation is also more likely. Since 1998, the UK has experienced six of the ten wettest years on record. Winter storms in 2015 were at least 40% more likely due to climate change.
This tool is the result of a collaboration with the BBC. It uses our climate forecasts and records to visualize UK climate change.
Even if we cut greenhouse gas emissions, sea levels around the UK will continue to rise after 2100. Parts of the UK will be at risk of flooding, with low-lying and coastal cities particularly at risk.
How Does Climate Change Affect Coral Reefs?
UK agriculture will also be affected by climate change. Hotter weather and higher CO2 levels may make it easier for us to grow some crops or even allow us to produce new ones. However, with more drought expected, access to water may not be as easy, making it difficult for farmers to plan the growing season. Some of the crops we grow today may also not do well in warmer temperatures.
Floods, storms and extreme heat can damage buildings, disrupt traffic and affect health. Buildings and infrastructure must adapt to the new conditions. Businesses will need to plan in a changing climate. 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 the future conditions expected for the UK are available in the UK Climate Projections (UKCP18).
