Whatever the reason it's happening we should not contribute it causes, it's not in out best interests as a species.
It is quite likely that there are many sources contributing to the warming that is occurring right now and there is a theory about a solar output supercycle that happens over centuries that is supported by the historical and archeological records for the past 2,000 years. It's also possible, though I haven't seen anything that addresses it, that the Earth's core may have a similar cycle of variation in its heat and could be a contributing factor. We can't do anything practical to affect such sources. What we can do is modify our behaviour so that we don't contribute so much. The use of hydrocarbons is just one aspect. The replacement of green areas, which absorb heat and make use of it in the growing process (and thereby take carbon OUT of the atmosphere), with paving and buildings, the reliance on air conditioning in office blocks and failure to design and insulate buildings effectively all contribute to atmospheric warning and in many cities our activities generate a microclimate that is at odds with the natural local environment, not unlike the localised weather patterns we find on ocean islands such as those in the Azores and Madeiras.
We are a part of the problem and we are the only part that we can realistically control. What we don't need in the media's bite-sized lights is a bunch of scientists playing to the press by presenting just one uncontrollable facet of the total information package available instead of presenting a comprehensive picture and clearly identifying which parts we can control and which we cannot. It's inappropriate, unprofessional and irresponsible. These people, some of whom probably rely on vested interests for their funding, are not true scientists by any definition that I can understand. They are mercenaries who don't care about any collateral damage they may cause.
