Question

How much has the global temperature increased in the last 100 years? does anyone have evidence to prove this?

Answer 1

About 0.8 C (1.44 F)

Answer 2

It is a little less than 1 degree C. The evidence is not simple or easy to see. It involves taking of millions and millions of temperature readings from all over the world many times a day and averaging them over a whole year. It takes armies of people working full time to come up with the number.

Answer 3

The Evidence

OUR AVERAGE SURFACE TEMPERATURE HAS INCREASED .0.6 DEGRES CENTIGRADE over 100 years

The Causes

While there are natural forces to a changing climate, the recent changes in climate have been shown to be a result of greenhouse gas emissions. The concentration of carbon dioxide, a greenhouse gas, has increased by 31% in the atmosphere since 1750 as a result of anthropogenic emissions. These emissions are mostly due to fossil fuel burning, but also occur from land use change and deforestation.



The Future

As greenhouse gas emissions continue, there are various projections of the future climate. Specifically, the global average temperature is expected to increase by 1.4 to 5.8 degrees centigrade over the next 100 years. Warming is expected to occur more rapidly in northern latitudes than in southern latitudes. It is expected that there will be an further reduction in diurnal temperature ranges in most areas. Precipitation is expected to increase in northern latitudes, however there will be wide variations in regional precipitation increases. In addition, there will likely be an increase in intense precipitation events as well as an increase in the risk of drought. The global mean sea level is projected to rise by 0.09 to 0.88 meters over the next 100 years.

The proof ( is in the pudding) All scientists as shown by data and sources cited for your answers cite the same temperature increase from different site as ( per their calcutations. and findings.
