The evidence clearly points that:<p>1. CO2 causes the greenhouse effect. This can be replicated in aquarium. It&#x27;s a fact.<p>2. Burnind fossil fuels creates CO2 as material does not disappear. Carbon included.<p>3. CO2 is not absorbed by oceans. It goes to atmosphere. Measurable fact, documented by Mauna Loa observatory since 1956.<p>4. The change in radiation balance shows in significant ways. As is shown by change in glacier mass balance. Again measurable fact, easily understandable by layman.<p>It is not hard so far. We have human made climate change there. Now if we go into the &quot;what will happen and how much?&quot; territory, 99% of climate scientist agree that we don&#x27;t really know. There are educated guesses with freakishly huge error bars.<p>If we compare this to &quot;should smoking be banned&quot;, nobody speaks about 99% of doctors. &quot;Is flyin safe?&quot; and you don&#x27;t hear about 99% of engineers. This &quot;99% of climate scientists&quot; stuff makes the whole business sound like it&#x27;s matter of opinnion.
