The word “climate”refers to the overall weather condition of a region for several years. For instance, in the United States, Maine’s atmosphere is cool and icy in winter, while South Florida is warm all year round. Climate change is a major change in weather conditions — say, temperatures are getting colder, wetter, or dryer — over many decades or more. This is the longer-term pattern that separates climate change from natural weather variations. And though “climate change” and “global warming” are frequently used interchangeably, global warming — the recent increase in global temperature at the earth’s surface — is only one aspect of climate change.
The biggest challenge of our time is climate change, and we’re in a crucial moment. Climate change impacts are global and on an unprecedented scale, from shifting weather forecasting patterns that threaten food production to increasing sea levels that increase the risk of floods. Today, it will be more difficult and costly to respond to these impacts without drastic action.
EFFECTS OF CLIMATE CHANGE
- Climate change is going to be incredibly expensive.
Asset loss, droughts, forced relocation, and all the other negative things we’re going to mention would contribute to the global economy’s expense. The Natural Resources Conservation Council has already predicted that the United States Climate Disruption Budget — that is, things associated with drought, hurricanes, and rising climate disruption — was almost $100 billion. That’s just the beginning.
- Polydengue and malaria could circulate in the U.S.
The dangerous vector-borne illness is malaria, which claimed 627,000 lives in 2012 (A vector-borne illness is transmitted from one human to another via a third organism, such as a blood-sucking bug) as summers get longer, temperatures increase, and patterns of rainfall change along with patterns of species. According to the Natural Resource Protection Council, disease-bearing mosquitoes are likely to have a more extended season in the broader region.
- Wildfires cause harm to our environment.
Wildfires are destroying communities all over the world. These destructive natural disasters are scarring our ecosystems from the mass damage they inflict to the cost of the loss of human life, animal, and plant.
Yet, in addition to the catastrophic injuries and deaths that can result directly from massive forest fires, these climate-forced events can destroy infrastructure that can:
- Endangered water quality and food supply
- The quality of the air we breathe is drastically decreased
- Jeopardize access to life-saving services for extended periods.
- Affirmative Change in precipitation trends
Since 1900 there has been a rise in the average United States precipitation, but some areas have increased more than the national average, and other areas have decreased. Over this century, more winter and spring rainfall is expected in the northern part of the United States, and less in the Southwest.
Future climate forecasts in the U.S. indicate that the recent pattern towards increased heavy precipitation events will continue. This pattern is predicted to continue also in regions where total precipitation is expected to decline, such as the Southwest.
- The Hurricanes Will Be Stronger and More Frequent
The strength, frequency, and duration of the North Atlantic hurricanes and the frequency of the strongest hurricanes (Categories 4 and 5) have increased since the early 1980s. The relative contribution of human and natural factors to these rises is still unclear. Hurricane-associated storm strength and rainfall are expected to increase as climate change continues.
- Climate-related mass migration.
Climate change is also contributing to a rise in migration, with people forced to vacate their homes due to drought, floods, and other climate-related disasters.
In 2007, for example, water shortages, crop failures, and livestock deaths due in part to climate-related drought had forced an estimated 1.5 million people from rural areas in Syria to towns, helping to ignite the horrific civil war that has displaced millions more.
The indirect effects of climate change that directly impact us humans and our environment include:
- Increased hunger and water scarcity, particularly in developing countries.
- Health threats due to increasing air temperatures and heatwaves.
- A rise in the spread of pests and pathogens.
- Loss of biodiversity due to reduced adaptability and adaptation pace of flora and fauna.
- Acidification of the oceans due to increased concentrations of HCO3 in water as a result of increased concentrations of CO2.
