DESPAIR:
ACTION and HOPE:
We can take action to make things better – and we must.
DISENGAGED:
It’s too late to do anything about it.
DISAVOW:
Climate change may be happening, but it’s not caused by
humans.
DENY:
The earth is not getting warmer.
DISMISS:
Climate change isn’t a bad thing, so not to worry.
I don’t know,
and I don’t care.
Data that anthropogenic global warming (AGW) is occurring seems to be compelling.
A large majority of climate scientists agree g j y gwith the basic tenets of AGW.
The consequences of not acting to mitigate emissions could be catastrophic.
Engineers have a professional and ethical obligation to protect the public.

Guideline 3: Professional Seals and Signatures
Meaning of Seal and SignatureThe seal and signature of a licensee on a document i di t th t th li t k f i l indicates that the licensee takes professional responsibility for the work and to the best of the licensee’s knowledge and ability, the work represented in the document is accurate, in conformance with applicable codes at the time of submission and has been prepared in conformance with normal and customary standards of practice and with a view to the safeguarding of life, health, property and public welfare.
Value #1
Protection of the public welfare above all other considerations.other considerations.
Goal #4
Advocate U.S. public policy pertaining to engineering matters in the interest of enhancing public health, safety, and welfare.
