How is Australia affected by climate change?

Australia is experiencing higher temperatures, more extreme droughts, fire seasons, floods and more extreme weather due to climate change. Rising sea levels add to the intensity of high-sea-level events and threaten housing and infrastructure. The number of days that break heat records has doubled in the past 50 years.

How does heat affect plant growth?

As temperature increases (up to a point), photosynthesis, transpiration, and respiration increase. When combined with day-length, temperature also affects the change from vegetative (leafy) to reproductive (flowering) growth.

How does climate affect agricultural production?

Extreme climatic events such as flooding, extreme heat, and drought has led to soil degradation which results in low crop yields. Decline in agricultural productivity discourages the farmers and may lead to change in livelihood especially in the rural settings.

How does climate change affect the agricultural sector?

The impacts of climate change on agriculture include; Shortening of Growing Season Length (GSL), heat stress at critical reproductive stages and increased water requirements of crops. These factors cause a decrease in yield in arid and semi- arid regions by about 6 -18%.

How do heat waves affect crops?

The heat waves also cause droughts and wildfires — which in turn, affect crops, too. … Extremely dry, hot weather conditions like these often result in droughts because rainfall becomes less and less frequent, and the soil dries out.

What are the 3 main impacts of climate change?
