Climate wouldn't have been worsened as much as it did without the technological advances provided by science. It's really, really difficult to cut the Amazonian forrest down using just axes and horse-drawn carts, but once you got mechanised stuff (with the help of science) then it becomes exponentially easier to do it (think just how much science went into the fabrication of bitumen/asphalt, once you have bitumen roads going into and out of the Amazon things get exponentially easier for those who are in the business of cutting trees in there).
Which is to say that I fail to understand how come some of us still believe science and technology can get us out of this mess when it was science and technology that brought us here.
To be clear, I also fully acknowledge that without science and technology our lives would have been way harder, for most of us life wouldn't have been possible at all: without science we would have had no green revolution, which means we still would have had famines around the world, never mind that the green revolution caused a lot of environment-related nasty things, so it's not always black and white.
