I Believe In Science Of Climate Change

The climate is changing and has been doing ever since the planet had anything that can be called a climate - which is far before the dinosaurs appeared. These changes though are slow, with small-scale superimposed oscillations.

We are still in an Ice Age, and the Earth's overall climate is relatively cool in terms of the planet's history. We are either still warming in an interglacial or (and far more worryingly for the future) at the end of the entire Ice Age. I don't know if that has been established, albeit only on probabilities. The "end" of the last glaciation is taken as being 10-12 000 years ago.

To explain that point, an Ice Age such as ours is NOT a single cold snap but a long-term cold/warm oscillation with consequent sea-level rises and geological effects, measured over hundreds of thousands of years.

The present concern to the extent of orthodoxy is that the present change is all by human activities, but this ignores any natural change.

This being so, I would like to know - from genuine scientists, not ignorant deceitful or corrupt politicians and campaigners - the relative proportion of human to natural change. I do not recall seeing or hearing such figures.

We cannot be complacent, but although we might be able to ameliorate [i]human [/i]effects, we can do nothing to alter [i]natural [/i]changes and their rates of change.

Modern Humans evolved well under 1 million years ago, but not so late that individuals in higher latitudes did not occupy glacial or intervening interglacial conditions. The last interglacial was warmer than now, with sea-levels about 10 metres higher than present. The last glaciation covered the land with ice Southwards nearly to the latitude of the English Channel, which was a river-valley due to the low sea-level. How did they cope? Easily.

There were far fewer of them, and like their surrounding wildlife they took their contemporary geography and climate as they found them, so adapted or moved to more equable regions.

How would 21C humanity cope with either case, and especially a warming or cooling rapid enough for human history, let alone geology? (E.g., 2 or 3ºC and sea-level change of a few metres, per century). Anything but easily.

The Earth's modern, far, far larger population and mix of complex, fractious societies living in almost all parts of the world, would find adapting to potential results of such a warming and its consequent "marine transgression", extremely difficult, to say the least. That is whether the changes are entirely natural, entirely anthropogenic, or both.

The natural history of the earth shows climate is always changing. l have no doubt that it is changing now and will one day be much warmer and one day it'll be much cooler. Human activity does not have a measurable impact on this change.

first it was global warming.that didnt work,now it's climate change

Human-caused climate change is an irrefutable fact. And it's happening not sometime in the future but now. Glaciers are melting. The fact that you don't believe in it changes nothing.

Climate change is caused by burning fossil fuels, creating carbon emissions from cars, trucks and industrial sources. It is human caused. The evidence is overwhelming. In the 21st we will have to discontinue using fossil fuels and plant trees to recover from the effects of human-caused climate change.

Statement on Climate Change from 18 Scientific Associations
"Observations throughout the world make it clear that climate change is occurring, and rigorous scientific research demonstrates that the greenhouse gases emitted by human activities are the primary driver." (2009)

Earth has an orbit that changes every 405,000 years. This was going on before the dinosaurs even.

It’s a scare tactic. Just like the ozone layer has not been talked about as well as acid rain.8

Heat waves are awful though climate change or not 😣😣
