Consequences of global warming

img-2

The average surface temperature of the Earth has been steadily rising over time, mostly as a result of the atmospheric accumulation of greenhouse gases, which is referred to as global warming. Carbon dioxide (CO2) is the main greenhouse gas linked to the phenomena, although others including methane (CH4), nitrous oxide (N2O), and several industrial gases also have a role.

Here are some of the key consequences:

Rising Temperatures

Global average temperatures rise as a result of global warming. Heatwaves may arise from this, which might harm people’s health, raise the danger of wildfires, and strain ecosystems. Additionally, high temperatures might decrease agricultural output and jeopardise food security.

Sea-Level Rise

Sea levels increase as a result of glaciers and polar ice caps melting as a result of rising global temperatures. Coastal towns are at risk from rising sea levels because they will experience more coastal erosion, floods, and saltwater intrusion into freshwater supplies. Small island countries and low-lying coastal areas are especially at risk.

Extreme Weather Events:

Extreme weather conditions including hurricanes, cyclones, droughts, and heavy rain events become more frequent and intense as a result of climate change. Devastating effects from these occurrences may include property damage, infrastructure breakdown, fatalities, and community displacement.

Melting Glaciers and Polar Ice:

The loss of freshwater supplies is a result of glaciers and ice sheets melting faster due to global warming. Additionally, it contributes to the Arctic sea ice melting, which has an impact on marine ecosystems and wildlife habitats. Further warming results from the loss of ice because it is less able to reflect sunlight back into space.

Biodiversity Loss:

Global biodiversity is at danger from climate change. Due to shifting temperatures and damaged ecosystems, many species are experiencing habitat loss, changed migratory patterns, and an increased danger of extinction. The functioning and services provided by ecosystems, such as pollination, nutrient cycling, and natural pest management, can be adversely impacted by biodiversity loss.

Ocean Acidification

Ocean acidification results from the seas absorbing more carbon dioxide from the atmosphere. Coral reefs, shellfish, and other marine animals having calcium carbonate shells or skeletons can suffer damage from acidic seas. This affects fisheries, marine ecosystems, and populations’ reliance on marine resources for their livelihoods.

Health Impacts

Human health is impacted by global warming. Heat-related diseases and fatalities can result from heat waves. Climate change has an impact on the transmission of vector-borne illnesses including malaria and dengue fever. Additionally, the air pollution brought on by the burning of fossil fuels is a factor in cardiovascular and respiratory illnesses.
