What I'd like to know is why did the CIA (of all government agencies)
open up the Center on Climate Change and National Security? No
one can get any information from them through FOIA because everything they
do is classified.
If the CIA is involved you can bet it's not in our best interests. They serve
the banks and corporations. So whatever the truth might be, it's being
deliberately kept from us.

Nile gauge records of variations in Nile floods from the 9th century to the 15th century AD reveal pronounced episodes of low Nile and high Nile flood discharge. Historical data reveal that this period was also characterized by the worst known famines on record. Exploratory comparisons of variations in Nile flood discharge with high-resolution data on sea surface temperature of the North Atlantic climate from three case studies suggest that rainfall at the source of the Nile was influenced by the North Atlantic Oscillation. However, there are apparently flip-flop reversals from periods when variations in Nile flood discharge are positively related to North Atlantic warming to periods where the opposite takes place. The key transitions occur atAD 900, 1010, 1070, 1180, 1350 and 1400. The putative flip-flop junctures, which require further confirmation, appear to be quite rapid and some seem to have had dramatic effects on Nile flood discharge, especially if they recurred at short intervals, characteristic of the period from the 9th to the 14th century, coincident with the so-called Medieval Warm Period. The transition from one state to the other was characterized by incidents of low, high or a succession of both low and high extreme floods. The cluster of extreme floods was detrimental causing famines and economic disasters that are unmatched over the last 2000 years.
Direct observations find that CO2 is rising sharply due to human activity. Satellite and surface measurements find less energy is escaping to space at CO2 absorption wavelengths
Climate change is very real. I spent four years studying its affects. I find it odd that most climate change sceptics are american.. It looks to me like they have been spoon fed a lie...
You spent four years investigating the climate and came to the conclusion that climate change is real. Congratulations! Those are some impressive detective-skills. I spent 30 seconds looking at paleo-climate data, such as the Vostok ice-core data, and came to the same conclusion: Climate change is real. It's been happening for approximately 4 billion years and no-one with half a brain-cell doubts it.
This is the problem with the majority of the AGW believers. Most of you, if not all are completely ignorant on the topic

Somebody might have already commented this but we are actually entering into another ICE AGE. I live in Seattle and so I welcome the fact that our atmosphere may be becoming more dense. This way when the climate drops considerably we'll have a greenhouse effect that can potentially negate it. I mean look at the mini ice age during the middle ages and the impact it had on the population. It caused the Vikings to stop colonizing North America among other things...
Other large volcanic eruptions (with VEI at least 4) during the same time frame are: 1812, La Soufrière on Saint Vincent in the Caribbean 1812, Awu on Sangihe Islands, Indonesia 1813, Suwanosejima on Ryukyu Islands, Japan 1814, Mayon in the Philippines These other eruptions had already built up a substantial amount of atmospheric dust. As is common following a massive volcanic eruption, temperatures fell worldwide because less sunlight passed through the atmosphere.
You are correct that climate has always been in a state if dynamic flux... However it is a little short sited to spend thirty seconds to come to a conclusion.. Evidently you have spent very little time studying the facts.... Spend some more time investigating and see what different fasctors are involved with the changes occurring in the climate today.
I know people that have been working on this for over a decade and still dont understand it...and you look at one little graph and think you do..
