Global Temperatue Chart 2500 BC to Present

Thechart above does not really need any words, it is pretty self explanitory. Though we should do whatever we can to eliminate polution and take care of our environment, the chart shows that Global warming and cooling will go on with or without mankind's involvement

415,000 Year Temperature Graph
...

This graph and the graphs below are drawn from the data gathered from the Vostok ice core samples and, unlike the tree ring data, is scientifically sound and uncontroversial. Looking at the above graph, there have been six periods in the last 415,000 years when global temperature exceeded today’s temperature by as much as nine degrees. 10,000 years ago, the global temperature was five degrees higher than today. Hey, wait a minute, polar bears have been around longer than 10,000 years, haven’t they? Yeah, they’ve been around for about 200,000 years. Which means that in the world according to Gore, they should have gone extinct twice by now.

Alright, so let’s drill down and look at global temperature over the last 16,000 years…

Reconstructions of Northern Hemisphere temperatures for the last 1,000 years according to various older articles (bluish lines), newer articles (reddish lines), and instrumental record (black line)

The temperature record of the past 1,000 years describes the reconstruction of temperature for the last 1000 years on the Northern Hemisphere. A reconstruction is needed because a reliable surface temperature record exists only since about 1850. Studying past climate is of interest for scientists in order to improve the understanding of current climate variability and, relatedly, providing a better basis for future climate projections. In particular, if the nature and magnitude of natural climate variability can be established, scientists will be better positioned to identify and quantify human generated climate variability (commonly referred to as 'anthropogenic global warming' (AGW). Although temperature reconstructions from proxy data help us understand the character of natural climate variability, attribution of recent climate change relies on a broad range of methodologies of which the proxy reconstructions are only a small part [1] [2].

According to all major temperature reconstructions published in peer-reviewed journals (see graph), the increase in temperature in the 20th century and the temperature in the late 20th century is the highest in the record. Attention has tended to focus on the early work of Michael E. Mann, Bradley and Hughes (1998), whose "hockey stick" graph was featured in the 2001 United Nations Intergovernmental Panel on Climate Change report. The methodology and data sets used in creating the Mann et al. (1998) version of the hockey stick graph are disputed, most notably by Stephen McIntyre and Ross McKitrick.
