Climate Change Disaster !

Please write to LNR to explain, what exactly is the big disaster with a "slightly' warmer climate and some rising sea levels ? What is the huge danger that the pseudo-scientists are screaming about (the louder they scream the more funding they get right) ? Please submit a list of the "catastrophe" the earth is facing with a warmer climate of which the earth has experienced many times before without disaster ? Of course, that is if the weather people are actually even correct in their computer modeled extrapolation theories that are to take effect 100 years from now- despite their inability to tell me what the weather is going to be like next month.
