Welcome, eco-wise viewers, to Planet Earth: Our Loving Home. Through a
complex interaction of changing flows of deep sea currents, warming
oceans, ice sheet melting at the poles, fluctuating global wind patterns
and other factors, extremes at both ends of the temperature scale are
being recorded across our world due to climate change. Dr. Zong
(m): So in the last 200 years, we saw the temperature was rising. That
changed the long-term climate trajectory, which is very, very strong
evidence for the argument that recent climate warming is due to meat.
The warming trend is going to continue in the next few decades and it's
quite, quite foreseeable that some extreme weather can happen more
frequently because within the atmosphere it has more energy and the
atmosphere becomes more dynamic.
Climate change researchers have
found that animal agriculture is overwhelmingly responsible for the
warming of our planet. Today we’ll focus on intense cold-related events
and disasters which are one of the many harmful consequences of this
enormously injurious activity.
Extreme cold events typically
occur when temperatures in a region drop significantly below the average
for that time of year. Humans, animals, plants and crops may be at risk
in such weather, and public infrastructure is also susceptible to
damage or destruction. For humans, exposure to frigid weather, whether
indoors or outdoors, in some instances may cause serious health problems
or even death. Highly vulnerable groups during these periods
include infants, the elderly, outdoor workers, the homeless and those
living in homes that lack heat or are not well-insulated.
Depending
on how far the temperatures dip, the cold may induce hypothermia, where
victims show symptoms such as shivering, exhaustion, confusion,
fumbling or uncoordinated movements, memory loss, slurred speech and
drowsiness.
Another common health risk is frostbite, where the
affected person may exhibit white or grayish skin and blisters as well
as experience itching and/or numbness. Amputation may be required in
some instances for severely frost-bitten areas of the body.
Freezing
weather may also exacerbate existing health issues, especially chronic
conditions. Crop damage from the chilliness may cause malnourishment in
communities. Let us now review some of the cold-related disasters that
have occurred across our world thus far in 2010, starting with Asia.
