What are the advantages of global warming?
There are very few real advantages to global
warming because global warming is causing climate change.
- More rain in some places might seem to be a benefit, but other
places will experience drought and famine.
- Increased warmth and increased carbon dioxide are thought by
some to encourage plant growth. Studies are showing that this is
usually not the case. Farmers will have to change to different
crops to deal with increased temperatures.
- Warmer climates may have some benefits for cold countries, but
the warmth is also melting frozen tundra, releasing methane, and
increasing the rate of global warming.
- Warmer climates are not beneficial for equatorial countries
that are already warm.
- There is no advantage in sea level rise, especially to the
world's great cities built on low-lying coasts.
- Ocean acidification is another disadvantage to increased
Every small advantage that might result tends to be
counterbalanced by much more severe disadvantages elsewhere.
A: Some known benefits:
- Increased agricultural productivity & land (more rain,
warmth & CO2)
- Longer growing seasons for plant life.
- Greening of some of the Earth's vast frozen land masses
- Increased wildlife habitat, provided migratory pathways to new
locations can be found and populations can take hold.
- More bountiful food for animal life (or less in areas subject
- Less net global energy heating requirement for humans (offset
by increased need for cooling--air conditioning tends to be more
expensive than heating).
- Less cold related severe weather and death (offset by increases
in heat stroke--far more people tend to die from heat than cold
- More pleasant temperatures for economic activity and outdoor
- If we are very lucky and warm enough, we may even avert the
next ice age. These occur like clockwork and wipe out substantial
animal and plant life on the planet.
- Animals and birds may not need to migrate so far for water (and
food as a consequence of the extra water).
- Tropical Rain forests- Global warming could
see these increase.
- The benefits do not even come close to the drawbacks
Climate scientists are realistic about what their modelling can
achieve. They know they can predict global warming with some
accuracy, and they know that they can predict some of the likely
consequences of global warming, but most of the predicted outcomes
are expected to be negative, including loss of biodiversity,
widespread economic and social hardship, and risk to health.
However, among the losers there are likely to be some winners. For
example, scientific predictions are for more prolonged droughts in
some areas and for more frequent severe flooding in others, but
there may well be other areas that benefit by more optimum
