Probability factor
Where
mean, σ = std. deviation.
- For z = 0, P(z) = 50%
- For z < 0, P(z) < 50%
- For z > 0, P(z) > 50%
In this probability distribution, the curve is symmetric about mean that is
The area covered under the entire curve is 1 unit. So area covered upto a point which is less than mean will be less than 50%.

In a world affected by climate change, we can expect to see various impacts on the environment, society, and economy. Some of these impacts may include:
1. Rising temperatures: Climate change is expected to lead to rising global temperatures. This can result in heatwaves, droughts, and increased risk of wildfires. Higher temperatures can also disrupt ecosystems and cause biodiversity loss.
2. Changing precipitation patterns: Climate change can lead to changes in rainfall patterns, including more intense rainfall events and longer periods of drought. This can have significant impacts on agriculture, water availability, and the overall water cycle.
3. Sea-level rise: As temperatures rise, glaciers and ice caps melt, leading to an increase in sea levels. This can result in coastal erosion, flooding, and the displacement of coastal communities. It can also contaminate freshwater sources with saltwater intrusion.
4. Extreme weather events: Climate change is linked to an increase in extreme weather events such as hurricanes, typhoons, and cyclones. These events can cause widespread destruction, loss of life, and infrastructure damage.
5. Impact on ecosystems: Climate change can disrupt ecosystems and lead to shifts in species distribution and abundance. This can have cascading effects on biodiversity, food webs, and ecosystem services such as pollination and water purification.
6. Health impacts: Climate change can have adverse effects on human health, including increased heat-related illnesses, the spread of vector-borne diseases, and reduced access to clean water and sanitation.
7. Economic implications: Climate change can have significant economic implications, including increased costs for disaster response and recovery, decreased agricultural productivity, and the potential displacement of industries such as tourism and fishing.
8. Social and political consequences: Climate change can exacerbate existing social and political inequalities, leading to social unrest, migration, and conflicts over resources such as water and land.
9. Impacts on vulnerable populations: Certain populations, such as low-income communities, indigenous peoples, and small island states, are particularly vulnerable to the impacts of climate change. They may face disproportionate risks and limited resources to adapt and recover.
Overall, climate change is a complex global issue that requires urgent action to mitigate its impacts and adapt to the changes that are already occurring.
