The need for the comfort and higher values

Writing about cost-effective approaches to global warming, Nigel Lawson says,

It is, I suspect, no accident that it is in Europe that climate change absolutism has found the most fertile soil. For it is Europe that has become the most secular society in the world, where the traditional religions have the weakest popular hold. Yet people still feel the need for the comfort and higher values that religion can provide; and it is the quasi-religion of green alarmism and what has been termed global salvationism - of which the climate change issue is the most striking example, but by no means the only one - which has filled the vacuum, with reasoned questioning of its mantras regarded as a form of blasphemy.

Does that mean that globally there is a relatively high proportion of secularists amongst environmentalists?
