CHALLENGE

$100,000 will be awarded to the first person to prove, in a scientific manner, that humans are causing harmful global warming. The winning entry will specifically reject both of the following two hypotheses:

UGWC Hypothesis 1
Manmade emissions of greenhouse gases do not discernibly, significantly and predictably cause increases in global surface and tropospheric temperatures along with associated stratospheric cooling.

UGWC Hypothesis 2
The benefits equal or exceed the costs of any increases in global temperature caused by manmade greenhouse gas emissions between the present time and the year 2100, when all global social, economic and environmental effects are considered.

There is, however, one slight hitch:

RULES

By submitting an entry to the contest, entrants agree to the following terms and conditions:

1. Entrants agreed to be bound by the UGWC Rules.

2. Entrants acknowledge that the concepts and terms mentioned and referred to in the UGWC hypotheses are inherently and necessarily vague, and involve subjective judgment. JunkScience.com reserves the exclusive right to determine the meaning and application of such concepts and terms in order to facilitate the purpose of the contest.

There you have it: simply scientifically disprove Steven Milloy's subjective interpretation of a vague concept. Well, can you? What? No responses yet? Hmmh...hippie alarmist!
