I care about the Earth and climate change.<p>However I think those of us with rational, logical minds might have reservations about a group of scientists who can be so sure that the earth is warming and that human activities are the definite cause of it.<p>So most of us might be a little quiet on the issue of climate change since we&#x27;re not positive that human activity is definitely the cause of it and temperatures are definitely going to rise 2 degrees (C) causing all kinds of calamaties.<p>I think this explains why you don&#x27;t wee more votes, comments and tweets about it from engineers&#x2F;developers.<p>I think we should definitely reduce emissions, I think the policies being pursued are justified and smart to do just in case this theory is accurate.<p>My problem is scientists saying that without doubt human activities are definitely causing the global temperatures to rise. At this point in time with the data we have how can we be sure. It needs more study&#x2F;data.<p>I&#x27;m definitely not saying that&#x27;s an excuse for inaction. Reduce emissions now just be careful about over stating what we really know for sure.<p>I think a more scientific approach would be to say that our data is pointing in that direction we need to reduce emissions now just in case, here are our finding and our data. We welcome other theories and review of our data and we are going to collect more and more data to track this trend and determine if our theory is accurate.<p>The Earth goes through climate cycles&#x2F;changes over time. Ice Ages, warm periods, little ice age, etc. And all of these changes&#x2F;cycles previously were independent of humans or human activity.<p>I&#x27;m not saying humans are not the cause of it, I&#x27;m just saying lets hold off on saying they definitely are, collect more data&#x2F;and more accurate data, be open with the data and work together, be open to new theories, then determine what is really happening while reducing emissions at the same time.<p>Also there is a possible solar minimum coming that might cause a 30 to 40 year little ice age.  Maybe that will give us some time to develop some break through technologies that nearly eliminates the need for using fossil fuels while avoiding the predictions of increased hurricanes, sea levels rising, etc if temperatures would rise.<p>Most of all improve, perfect and invent green energy sources so we can eliminate most emissions.<p>The Earth is amazing, lets take care of it.
