I read somewhere, just after the USSR collapsed, that half the weather stations were closed down due to lack of funds, so the Russian weather data is suspect, plus with urban sprawl, airports are now in the middle of a 'heat islands' more suspect weather data, and just how does a satellite measure the temperature of the sea?
The radiation has a specific spectrum and intensity that depends only on the temperature of the body.

This laser thermometer accurately measures temperatures of hard-to-reach areas and hazardous materials (like car engines and other machinery) from a safe distance! The infrared thermometer accurately measures up to 1/10th of a degree in Celsius or Fahrenheit on its LCD display! Features include an ergonomic trigger to give you total control, making this a great laser thermometer for mechanics and machinists to safely check the heat before getting back to work.

Do you have any proof that AGW is not real?
Do you even know what the residence time of CO2 is in the atmosphere? What about radiative forcing?
Unless you actually have an understanding of Atmospheric Chemistry, then you really have no business trying to debunk what is apparent.
We have seen a 40% increase of CO2 as a result of the industrial revolution. CO2 causes radiative forcing.....

Both sides seem to be making up a lot of crap. Never the less, we can't keep putting unnatural or concentrated chemistry into our environment, especially if we are dampening it's ability to repair itself.

I do not know particulars of the chemistry needed to balance the CO2, but many climate scientists do know the answer to that.

Computer models are relevent to a certain point, if they have accurate information fed into them. Most of the real climate scientists see there is a problem and are not sure what is actually happening, they are forced to try to produce evidence to prove what is exactly happening. But we are effecting our planets weather patterns somehow, We are exceeding our natural negative contribution to the environment we are living in.

On the Misdiagnosis of Surface Temperature Feedbacks from Variations in Earth’s Radiant Energy Balance†

Abstract: The sensitivity of the climate system to an imposed radiative imbalance remains the largest source of uncertainty in projections of future anthropogenic climate change. Here we present further evidence that this uncertainty from an observational perspective is largely due to the masking of the radiative feedback signal by internal radiative forcing, probably due to natural cloud variations. That these internal radiative forcings exist and likely corrupt feedback diagnosis is demonstrated with lag regression analysis of satellite and coupled climate model data, interpreted with a simple forcing-feedback model. While the satellite-based metrics for the period 2000–2010 depart substantially in the direction of lower climate sensitivity from those similarly computed from coupled climate models, we find that, with traditional methods, it is not possible to accurately quantify this discrepancy in terms of the feedbacks which determine climate sensitivity. It is concluded that atmospheric feedback diagnosis of the climate system remains an unsolved problem, due primarily to the inability to distinguish between radiative forcing and radiative feedback in satellite radiative budget observations.

There is no evidence to prove that the earth's ecosystem can handle the impact of the industrialized world we have today. In fact, most evidence shows it is faultering.

Maybe you want to believe it doesn't effect the environment because it negatively effects your way of life to believe otherwise. That is your right. I'm looking at the whole picture, and do understand I am also part of the problem, but I can lower my buying of unneeded things.

Successful indoor growers implement methods to increase CO2 concentrations in their enclosure. The typical outdoor air we breathe contains 0.03 - 0.045% (300 - 450 ppm) CO2. Research demonstrates that optimum growth and production for most plants occur between 1200 - 1500 ppm CO2. These optimum CO2 levels can boost plant metabolism, growth and yield by 25 - 60%.

A NASA-Department of Energy jointly funded study concludes the Earth has been greening over the past 20 years. As climate changed, plants found it easier to grow.
The globally comprehensive, multi-discipline study appears in this week's Science magazine. The article states climate changes have provided extra doses of water, heat and sunlight in areas where one or more of those ingredients may have been lacking. Plants flourished in places where climatic conditions previously limited growth.
"Our study proposes climatic changes as the leading cause for the increases in plant growth over the last two decades, with lesser contribution from carbon dioxide fertilization and forest re-growth," said Ramakrishna Nemani, the study's lead author from the University of Montana, Missoula, Mont.

Effects of Rising Atmospheric Concentrations of Carbon Dioxide on Plants

One of the most consistent effects of elevated atmospheric CO2 on plants is an increase in the rate of photosynthetic carbon fixation by leaves. Across a range of FACE experiments, with a variety of plant species, growth of plants at elevated CO2 concentrations of 475–600 ppm increases leaf photosynthetic rates by an average of 40% (Ainsworth & Rogers 2007). Carbon dioxide concentrations are also important in regulating the openness of stomata, pores through which plants exchange gasses, with the external environment. Open stomata allow CO2 to diffuse into leaves for photosynthesis, but also provide a pathway for water to diffuse out of leaves. Plants therefore regulate the degree of stomatal opening (related to a measure known as stomatal conductance) as a compromise between the goals of maintaining high rates of photosynthesis and low rates of water loss. As CO2 concentrations increase, plants can maintain high photosynthetic rates with relatively low stomatal conductance. Across a variety of FACE experiments, growth under elevated CO2 decreases stomatal conductance of water by an average of 22% (Ainsworth & Rogers 2007). This would be expected to decrease overall plant water use, although the magnitude of the overall effect of CO2 will depend on how it affects other determinants of plant water use, such as plant size, morphology, and leaf temperature. Overall, FACE experiments show decreases in whole plant water use of 5–20% under elevated CO2. This in turn can have consequences for the hydrological cycle of entire ecosystems, with soil moisture levels and runoff both increasing under elevated CO2 (Leakey et al. 2009).

Climate change is just a catch word that you through around to discredit 'activist' like me.
40% and rising as a result of human activity....

No. It is not a matter of scale.
Weather changes from day to day. Hour to hour.
Climate represents long term tendencies. Decades. Climatologists don't even pretend to predict weather because weather is not climate.
A couple maybe. But there were a lot more who were concerned about the warming effects of CO2.
When was it, the '70s when the climatologists were predicting that we were heading into another ice age?
I've lived for quite a while and no, climatologists have been concerned about the effects of increasing CO2 consistently, for decades.
When you live long enough you will see these climatological predictions change every bit as much as a local weather forecast will change over a 3, 5, and 10 day period.
