Climate change is a worldwide phenomenon in which there is a rise in the temperatures. Rise in temperatures can result into rise in sea levels. Extreme weather occurrences may be experienced. They include: floods, Storms and droughts. Outbreak of diseases may also occur. All these catastrophic events may have a negative effect on cities in terms of housing, health, infrastructure, basic amenities and human livelihoods.
However, it is evident that cities are also the major contributors of climate change. This is due to major industrial activities taking place in the cities. The industrial activities results in to the emission of large amount carbon dioxide into the atmosphere. If adequate measures are not taken in to place at national, regional or international levels, the world cities can be adversely be affected especially due to the green house effect that results from the depletion of the ozone layer. Therefore, it is the responsibility of every stakeholder to ensure that necessary measures are taken to save the cities.
It is impressive that many cities worldwide are now using renewable energy and safer production techniques to preserve the environment. There are also many regulations that have been put in place by many cities to curb this problem. They include the use of energy-efficient housing and vehicles with reduced CO2 emissions.
There are several publications that provide useful information on how to conserve the environment of cities so as to prevent environmental degradation that can ultimately result into climate change. They also contain support mechanisms that many cities can adopt to fight climate change.
It is worth mentioning that international bodies that are dealing with the environment and climate change have engaged cities in campaigns against climate change and have assisted them to reduce green house gas emissions. This has been done through trainings, workshops, provision of awareness promoting materials and climate change international meetings.
Therefore, it is advisable that everyone should take personal responsibility of conserving the environment so that climate change is gotten rid off. This can result in to reduction in the occurrence of diseases and increased agricultural activities hence food security.
