Global warming is defined as the continuous and unending heating of the earth’s climate system which is observed since the industrial period while on the other hand climate change is said to be a long-term change in weather patterns. Global warming is said to be caused by the increased human activities and fossils that are a result of fuel burning. The planet’s climate is constantly changing, and this global environmental problem is becoming more threatening for humanity. While some climatologists believe that climate change is a natural planetary process, most scientists believe that it creates many economic, environmental, and social problems. Overwhelming evidence of climate change confirms both the current impacts on agricultural productivity, food security, and well-being of many countries, as well as the extraordinary future risks to sensitive marine and extreme terrestrial ecosystems.
Impact of Climate Change on Agriculture Productivity
Agriculture is one of the economic sectors that have been largely affected by climate change. Production volumes have been greatly affected since it the numbers have reduced since the world started feeling the impacts of global warming.
According to Gupta et al. (2021), the effect of climate change on agronomy is assessed differently in different world regions. Countries with arid climates experience a negative impact on agricultural production, while countries with temperate climates benefit from global warming. Moreover, an unfavorable consequence of global warming is an increase in the frequency of weather anomalies, an increase in the populations of heat-loving pest species, and the spread of weeds and pathogens of dangerous plant and animal diseases. It can sum up that the downward trend in agricultural productivity is associated with climate change.
Dependence of food security and human well being on climate
There has been a tremendous impact of climate change on food security and human well-being. The rise in temperatures and severe changes in rainfall patterns and the frequent disasters are causing and affecting food security which includes both supply and access. Hunger levels have increased in large numbers due to persistent conflicts and economic downturns. Food insecurity will be a continuous problem in most developing countries due to increased heat waves, frequent floods and droughts, and storms. The frequent changes in climatic patterns will continue to pose a threat to food security as well as agricultural production and nutrition of the people. Gupta et al. (2021) state that agricultural productivity declines in developing countries due to global warming, and then food prices rise significantly which reduces the well-being of citizens. It can be concluded that climate change will affect and determine the food security and well-being of the people in most countries.
Effect of climate change on the sensitive Marine and Extreme Terrestrial Ecosystems
Marine and Extreme terrestrial systems have also been largely affected by climate change. Climate changes pose a severe threat to the ecosystem on earth, both on land and on the seas. Chen (2021) notes the impacts of climate change on sensitive marine and terrestrial ecosystems are expected earlier and more severe. These include sensitive tropical coral reefs and harsh conditions in the European Alps and the Arctic, focusing on snow and permafrost. Thus, it is essential to discuss and resolve environmental protection issues since climate change is destroying many ecosystem elements.
In conclusion, climate change is one of the most pressing global problems which influences both nature and society. It reduces agricultural productivity, raises food security issues, affects the well-being of many countries, and poses risks to sensitive marine and extreme terrestrial ecosystems.
