Let's put up some legitimate temperature charts.
Follow this link, half way down the page is a chart of Earth's temperature record for the last 1.35 million years. The planet's temperature increase
is still accelerating.
If you do more research, you will find that the last few years have been hotter than it has been for about 400,000 years.
The chart is accurate. Here is another plotted directly from composite data sets using Lotus 1-2-3.
The chart on the previos page is compiled from.
2000-1979: Satellite stratospheric data
1979-1871: S. Hemisphere ground temp. data
1871- 422k B.P.: Vostok Ice Core Data
Historically, glacial cycles of about 100,000 years are interupted by brief warm interglacial periods-- like the one we enjoy today. Changes in both
temperatures and CO2 are considerable and generally synchronized, according to data analysis from ice and air samples collected over the last half
century from permanent glaciers in Antarctica and other places. Interglacial periods of 15,000- 20,000 years provide a brief respite from the normal
state of our natural world-- an Ice Age Climate. Our present interglacial vacation from the last Ice Age began about 18,000 years ago.
Please do your homework before knocking others. Thank you!
Historical Isotopic Temperature Record from the Vostok Ice Core
The data available from CDIAC represent a major effort by researchers from France, Russia, and the U.S.A.
