a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.Climate change refers to changes in the Earth's average temperature. These changes occur naturally over time, but most scientists think that human behaviour is increasing the amount of
greenhouse gases
in the atmosphere, which is causing more rapid changes to the climate.
Evidence for climate change can come from tree ring analysis, ice core samples, and observations of changes in ice cover.
Climate change can be managed by
mitigation
and
adaptation
. Mitigation means reducing greenhouse gas
emissions
, and adaptation is learning to live with the effects of a warmer planet.Climate change refers to changes in the Earth's average temperature. Climate change occurs naturally through things like volcanic eruptions, changes in the Earth’s
orbit
and variations in the Sun’s energyIn recent years, temperatures have been increasing more rapidly than in the past. Global temperatures are around 1 °C higher than they were around 300 years ago. The
Intergovernmental Panel on Climate Change (IPCC)
report of 2021 says that global warming of 1.5 °C and 2 °C will be exceeded during the 21st century unless deep reductions in greenhouse gas emissions occur in the coming decades.

Greenhouse gases
Most scientists agree that human behaviour is causing this increase in temperature. Humans are increasing the concentration of greenhouse gases, such as
carbon dioxide
and
methane
, within the atmosphere.

Greenhouse gases can be released by human activity, such as:

burning of
fossil fuels
, which releases carbon dioxide into the atmosphere.

deforestation
, as trees absorb carbon dioxide and store carbon.
food waste, which creates methane when it breaks down.
Carbon dioxide
emissions
are now more than three times higher than they were in 1965. Greenhouse gases
absorb
any heat that is reflected from the Earth. A greater concentration of greenhouse gases means that more heat is absorbed and so the planet warms up...There is clear evidence that climate change is taking place. This includes tree ring analysis, ice core samples, and measurements of ice cover...Climate change is causing global temperatures to increase and average sea levels to rise. Scientists suggest that the impacts of higher temperatures and rising sea levels could include:

a change to the location of the Earth’s
climate belts
, which would make it difficult for some countries to grow food.
flooding of
coastal
and
low-lying

communities
.
the spread of
tropical diseases
, like
malaria
, to places that are further north and south.
Climate change can be managed by:

Mitigation – limiting or preventing greenhouse gas emissions. Examples of this are
renewable energy
, such as
solar panels
, and new technology, such as
electric vehicles
.
Adaptation – learning to live with climate change. Examples of this include building
flood defences
to protect against rising sea levels, and developing new crops that are
drought-resistant
.We need to look out for drastic steps to stop climate change since it is affecting the resources and life on our planet. We can stop climate change if the right solutions are put in place. Here are some strategies for reducing climate change:

Raising public awareness of climate change

Prohibiting tree-cutting and deforestation.

Ensure the surroundings are clean.

Refrain from using chemical fertilisers.

Water and other natural resource waste should be reduced.

Protect the animals and plants.

Purchase energy-efficient goods and equipment.

Increase the number of trees in the neighbourhood and its surroundings.

Follow the law and safeguard the environment's resources.

Reduce the amount of energy you use.

During the last few decades especially, climate change has grown to be of concern. Global concern has been raised over changes in the Earth's climatic pattern. The causes of climate change are numerous, as well as the effects of it and it is our responsibility as inhabitants of this planet to look after its well being and leave it in a better condition for.
