Climate change is the permanent change of weather and temperature in the atmosphere of a place. Human activities contribute the most drivers to climate change such as environmental degradation, burning fossil fuels, and coal. The burning of these materials releases greenhouse gases into the atmosphere leading to climate changes. This text will help understand the worst cases scenario in climate change.
Infectious Diseases Increase
Scientists have warned of the potential impact of climate change on the health of the ecosystem globally. The change in microbial activity may alter the existing occurrence and spread of diseases. Present information suggests that the spread of vector-borne diseases such as mosquitoes is linked to human-induced climate change (Cavicchioli et al., 2019). The spread of pathogens and the introduction of invasive species can have negative consequences in altering host and parasite interaction, which will cause unpredictable environmental outcomes.
Greenhouse Gas Emission
Human causes release of greenhouse gases into the atmosphere will change the environmental climate over the coming years. A recent study has warned that as the greenhouse gases such as carbon dioxide emissions increase and emissions exceed the atmospheric limits, the atmospheric temperature will likely increase by 2°C, causing potential catastrophic events such as heatwaves and droughts (Mitchell et al., 2016).
It is clear that many of the threats already facing the world will be worsened by the loss of land after climate change and related sea-level increases; industrialized countries have a moral responsibility to decrease their releases of greenhouse gases.
