The planet is warming faster due to the industrial revolution, overpopulation, and deforestation. Since 1970, the average global temperature has increased by 1.8 degrees Fahrenheit which is an alarming situation. Effects of climate change impacted directly human health and ecosystems. The impacts of global warming are also appearing in the shape of extreme weather events, glacier retreats, and sea level escalation.
Climate variability creates food insecurity in many places in different regions and puts water deep and deep. Climate change has also contributed to desertification and land degradation which leads to negative effects on human health and also creates ruthless complications for livelihoods as many people are reliant on land for food, feed, and energy. Rising temperatures also have negative effects on economic growth in developing countries. Here we discuss 4 major aspects of climate change and how we contribute to global warming decline.
Effects of climate change on!
- Food and Water
Food and Water:
Food and water are the essential needs of humans; elevated CO2 in the atmosphere and changes in temperature becomes growing crops more difficult. Changes in the timing of seasonal events also affect ecosystems and agriculture, and the growing season is projected to lengthen.
All up mentioned conditions create food insecurity in all aspects like food availability, food quality, food prices, and stability of the food system.
Rising temperatures are affecting glaciers, lakes, and water levels on earth; Glaciers, and ice sheets covering West Antarctica are melting vastly, and the water level goes down and down in the last century, these are the main source of fresh water in the world if we do not counter above mentioned condition we face freshwater issue badly at the end of this century and over next generation will fight to access fresh drinking water.
Climate change is one of the biggest threats to human sustainability on the planet, human have been exposed directly to heat waves, air, food quality, etc. In 2007, the World Health Organization estimated that 150,000 people were being killed by climate change-related issues every year. The effects of more frequent and extreme storms were excluded from this study.
Change in seasonal time increases crop pests, mosquitoes, ticks, and flies rate. That causes crops failure and is linked to different diseases like malaria, dengue fever, and Diarrhea. Furthermore, Heatwaves directly hit the human body as dehydration and indirectly affect other body organs. High temperatures can also affect blood glucose levels and heartbeat rhythm. In 2018, according to a report about the impact of climate change on mental health by the American Psychological Association that long-term changes in climate also float up a number of different emotions, including fear, anger, powerlessness, and exhaustion. Generally, this is likely to have the utmost impact on young people.
High-temperature cause melting ice and contributes to sea-level rise. According to NASA research, Global sea levels are increasing by 0.13 inches a year, and the increasing rate is high in recent years.
Other possible effects include warming of the ocean surface and large-scale changes in ocean circulation. The oceans also serve as a sink in absorbing carbon dioxide and extra heat from the atmosphere and high levels of carbon dioxide have led to ocean acidification.
Indirect climate change impacts on the oceans are marine deoxygenation, an increase in marine heatwaves, tropical cyclones, and other storms. Consequences of ocean deoxygenation and marine heatwaves include decreased biodiversity, shifts in species distributions, and a decline in fishery resources.
High temperature makes weather extreme, which means not only facing both days and nights become warmer it’s also linked with heavy snowfall and floods, droughts, cyclones, and rainstorms. Scientists claim that such events will occur more often and with greater intensity in the coming days.
Climate change may also lead to Heatwaves, Cold waves, Tropical cyclones, Flooding, Droughts, and Wildfires severity and frequency, an extreme spell of any mentioned weather lead to a big disaster and irretrievably loss.
The human contribution to global warming decline:
The future impact of climate change depends on the execution of prevention efforts on the world level.
At the international level encourage support for clean energy technologies, curb deforestation, and Policies to control emissions of carbon dioxide, methane, nitrous oxide, Water vapors, and greenhouse gases.
“Strict mitigation policies, controlled use of fossil fuels and increase in greenery might be able to limit global warming.”
