Question

How much does the global temperature rise each year because of global warming?

Answer 1

It varies from year to year due to weather, but here's a chart showing the general upward trend of about .2 degrees C per decade for the past three decades:

Answer 2

About .01 to .02 degrees C, on average.  It's slowly accelerating.  Estimates of warming in the next 100 years range from 2-4 degrees C.

Answer 3

Each year is different, it can rise and dip from one year to the next but if you look at longer periods such as 3 years or even 10 years in a row, a pattern should emerge if the climate is indeed changing.

But if you're looking for an average based on the last two decades it is currently about .03 degrees farenheit increase per year.  This figure is expected to increase further due to data that the recent climate change is accelerating as it increases as a result of side effects known as feedback loops (i.e. more ice melt reflects less energy back to space, darker exposed water absorbs more energy thus increasing warming, etc.).

But it should be noted, this is still being studied and is still rather controversial.  However, there is enough concern about it that research and anything we can honestly do which is more benefitial to the environment is likely a good idea anyway, especially if the data on future global warming ill effects prove to be in any way accurate.

Answer 4

i don't believe in global warming. it is political

Answer 5

There is no way to tell. There are so many variables that to assign a number to the man made global warming is tripe. And anyone who has figured out this for real should get the Nobel Prize. It won’t be the blithering idiot Gore.
