Global Warming Has Benefits

There are some good points about global warming. If you live off leaf vegetables you won't go hungry. Weeds and vegetables such as cabbage and lettuce grow much better with more carbon in the environment. Grass will also be thicker and grow faster, so cattle will fatten-up quicker.

The problem is herbicides will no longer be effective in controlling weeds. With the price of fuel going up this means they will have to be removed by hand in the future - a very arduous and expensive process.

It is conceivable that more herbicide will be used. This will pollute the environment. Diclofenac a chemical to reduce inflammation in humans and animals was widely used in India for cattle. The native vulture was nearly wiped out by consuming dead cattle carcases. More chemicals use is quite frightening. Similar disasters will probably occur.

Caterpillars Are Changing into Butterflies Earler

Climate change is making butterflies more violent. They are coming out 10 days earlier than they used to in spring. The change has been caused by a 0.91ÂșC increase in temperature in Melbourne. All species that interrelate with the Common Brown butterfly (Heteronymph Merope) breed earlier as well.

A group of academics funded by the Australian Research Council has researched this issue. Members of the group studied caterpillars bred at the old and new temperature in the laboratory and noted the changed. Observation of the butterfly in the wild has confirmed that caterpillars are changing into butterflies earlier.

If butterflies are coming out sooner then other insects must doing this as well. This means that crops will have to be planted earlier in to be fertilized by insects. People in cities do not understand the importance of pollination on food crops.
