Is mankind affecting the global climate yes or no?
Yes, mankind is one of the most important reasons for affecting
the global climate. Excessive industrialization, production of
non-degradable substances like plastic, excessive production of
carbon dioxide are the factors concerned with mankind affecting
No matter what names people choose to label other people - hoaxers, deniers, sceptics, whatever - regarding "global warming" (or nowadays "global climate change"!), major physical processes and events have been happening to the Earth throughout its long history and will keep on happening.
Some physical processes are continuous, taking place over a very long periods of time. Other physical processes take very little time by comparison: we humans have chosen to call some of those "catastrophic events" because they seem to have taken place with hardly any warning.
For the past 4,000 million years the outer crust of the Earth has been changing. Its tectonic plates, continually move around forming continents which then break up and re-form in other configurations. The friction caused by the sliding and subduction of the edges of plates against one another causes mountain chains to be thrown up and fiery volcanos to spew out new soil and smokey, noxious gases which pollute the atmosphere.
65 million years ago the dinosaurs were wiped out by a major event. It was probably a huge meteorite from outer space which suddenly hit the Earth. The resulting air pollution caused thousands of years of continuing global darkness and bitter cold because heat and light from our Sun could not reach the surface until the pollution was eventually absorbed by the Earth.
An ice sheet on Antarctica began to grow some 20 million years ago. The current ice age, the Pliocene-Quaternary glaciation, started about 2.58 million years ago during the late Pliocene when the spread of ice sheets in the Northern Hemisphere began. Since then, the world has seen cycles of glaciation with ice sheets advancing and retreating on 40,000- and 100,000-year time scales called glacials (glacial advance) and interglacials (glacial retreat).
The Earth is currently in an interglacial, and the last glacial period ended about 10,000 years ago. All that remains of the continental ice sheets are the Greenland ice sheet, the Antarctic ice sheet and smaller glaciers such as on Baffin Island. It is likely that people lived in the temperate zones of the Earth before that last glacial period began, along with other animals and plants. After the maximum had occured and the glaciers receded, modern humans were able to migrate from a belt of land around the Earth's Equator towards its poles.
All this says that the physical processes and systems which affect the Earth are much bigger - both in scale and in time - than anything which can be created by creatures who live on its surface or in its oceans. Is it credible that any of those creatures can really affect what happens to the Earth?
The simple answer is "No". For a more in depth answer the question would need to be clarified. Is the question "Does Global warming on Earth affect the climate of Mars?" or "Do other planets also experience global warming?" To "does Global warming on Earth affect the climate of Mars?" the answer is a very simple No. As far as anyone is aware there is no way that our climate can affect the climate of…
Yes. There already is global warming. The planet naturally goes through periods of climate change, and it always has. But the concern now is the rate at which these changes are taking place. The thinking is that because the rate of change of the global climate is so great, the changes cannot be due to "natural causes" but must also be influenced in a big way by the activities of man. Data concerning the increase…
Yes, the green house effect can cause considerable warming, affecting global climate and eventually destroying crops and our food sources. It may also have a connection with extreme weather like floods and hurricanes. Venus has a runaway green house effect in which temperatures have risen to 350 degrees Celsius - enough to melt lead.
Global warming is causing climate change, and yes, part of the climate change may mean some parts of the world will be wetter, even floods and rising sea levels, and other parts will be drier, with droughts and famine. There is already famine in much of Africa and climate change will lead to many more deaths than at present.
Yes. If a scientific theory cannot be "falsified" - that is, proven to be not true - then it isn't "scientific". A scientific theory will always lead to some tests that can be performed. If the test fails - that is to say, if your theory doesn't behave in accordance with the experimental results - then we can say that the theory is "disproved". This is the problem with a lot of the "global warming"…
