Sir, sorry for that delay, he said that it is the rapid rise in temperature in the last 60 years that all climatologists are considering/worried about. You keep on mentioning a period of 200 years. And is agree with the 1 C is a tremendous difference as a global means. And then one has to consider that temperatures in the Arctic are more rapidly increasing. He confirms the view of IPCC "human activities that have raised the CO2 and thus the temperature", and you always present a different view but do not confirm that the climate changes are natural and not because of human activities.
It is repeatedly highlighted that because of increasing population and related anthropogenic activities all the wrong things are happening to our environment. If the cause of climate change is due to the human activities, then by changing or controlling the local or regional activities, one can bring in global level changes. It is just like "Every Drop of Water Makes the Mighty Ocean".
Yes, the local human activities will affect the local weather. Even though, these weather changes will be temporal climate change but not permanent change. For example if you build a dam in any area, the humidity will increase in the near atmosphere. This will cause to change the agriculture plants to be affected. Thus any man made change will affect on local weather but these changes will be temporal. If we destroy dam the area will be back to its natural circumstances.
I don't agree to call it climate change i would say it is weather change.
Strongly, i can say human activities will never create global warming or cooling. Our nature and environment will deal to balance these micro and local weather changes.
Climate change or global warming or cooling will be affected by other reasons that related to earth position in our Galaxy.
Forget about global warming and global cooling, our earth will deal with it. Life will continue till its unknown end.
Forgive me professor Kenneth did the human activities rise the temperature because we used carbon to improve our lives? Or the increasing in temperature just a wave then the climate will pass it to another cool wave?
I think that the cooling effect due to reduced sun activity (if it exists) moderates anthropogenic warming impacts, the same other natural impact on the climate would such as volcanic eruptions etc. We should realise that something as complex as climate has many contributing factors that lead to change. To assume that everything is caused by humans or everything by natural causes is far too simplistic. For that reason it is rather difficult to make any precise predictions of the future.
Planet Earth is about 4.5 billion years old and in this long time there had been periods that were much, much warmer than it is today (e.g. during the time dinosaurs lived on our planet) and also periods that were far colder (ice ages). In other words: it would be strange when the climate would be the same indefinately. This never has been the case. There were also periods when CO2 concnetration was much higher than today. Indeed there was a time when no O2 was in the atmosphere... Climate change is something that bothers us, because we are effected, because we are there to be bothered. It does not effect Planet Earth in any meaningful way as the planet will be there even if Human aren't anymore (although also Planet Earth won't be eternal). Among many other challenges the scientific mainstream believes that the generation of special gases through the burning of fossil fuels is the driving force for climate change. A few, however, see human contribution little in global warming and some even talk of global cooling. In RG there have been many contributions that put global warming and global cooling as two different processes. What is different is the outcome of very complex processes. The outcome is either warming or cooling, and to make it even more complex both can happen - in different places.... or at differnt times (a specific place can have warmer summers and colder winters as a resukt of change of the climate....,). How much of this change is contributed by human activies we can discuss and do research about, but it would be strange if only humans have contributed to these changes, or if they would be entirely caused by natural processes - both is very unlikely the case. Sometimes people think that IPCC does investigate into global warming, but indeed it looks into climate change. The expression global warming is out since many years as it is acknowldeged that it is much more than around temperature change. Global cooling, if it exists is also climate change. In Germany we can have temperatures in winter of minus 20 degrees Celsius. That is winter and we call this winter weather. Some years winters are mild, other years very harsh, long and very cold. Weather and climate are different things, and the weather is never the same. It changes and also if the sun energy received on January 1 at a particular place would be the same every year (which is not the case as the sender (sun) sends not always the same) it still would result in different weather as the energy received is only one from many, many factors that makes the weather. In the discussion often people speak of a food crisis because of global warming. I doubt that this is the only possible interpretation. Today we produce considerable more food per capita than a few decades ago. When people are starving then it is usual because of the impacts of wars, civil wars, ethnic tensions, or just because of poverty, but not necessarily because of climate change, at least not so directly as often assumed. Here in the Pacific Island countries the talk of climate change and its impact on food security has been rather dominant, despite this part of the world does not know widespread undernutrition and when we look at malnutrition than we discover that the biggest concern is obesity, and when we would anlyze the causes then we would not find climate change, but MacDonalds and other fast food outlets.
