Do you still believe..

That there is still no such thing as global warming???

The fact that climate change is occurring is irrefutable, the suggestion that this change is man made is very convincing.

The point that many are missing is that climate change is inevitable, but to date it's been relatively slow in terms of an individual's perception. However that could all change and a catastrophe could suddenly be upon us. It is a known fact that atmospheric carbon dioxide has been steadily increasing since the start of the industrial age, over 150 years ago. This, in the upper atmosphere, acts as a filter allowing solar energy in, but blocking radiated energy going out. We call this the greenhouse effect.

Greenhouses are warmer on the inside because the solar energy gets in but the glass blocks the radiated energy getting out. Carbon dioxide in the atmosphere acts in much the same way as glass in a greenhouse. This is causing the earth to warm.
The increase in the average temperature of earth is causing the ice caps to melt, resulting in the sea level rising. This is only about 3mm per year at the moment. However it is imminent that the permafrost in the tundra will also thaw due to the temperature rise.

Only a couple of further degrees increase in average temperature will cause this to happen in summer times. Should the tundra thaw, millions of tons of trapped methane will be release into the atmosphere. Refreezing of the permafrost in winter will not recapture the released methane. Methane is a far more potent greenhouse gas than carbon dioxide, and when released the earth's temperature will experience thermal runaway, resulting in widespread flooding of the ports and major population centres, as the icecaps and glaciers melt, causing the sea level to rises over 60 metres. This will cause complete disruption to human and animal life on earth as we know it.

Action needs to be taken now to stop any further increase in carbon dioxide levels, and as there is a lag between carbon dioxide level increasing and average temperature increasing. We actually need to reduce atmospheric carbon dioxide now, to avoid the possibility of thermal runaway and the resultant catastrophic flooding of all coastal and low lying lands.

there's been global warming since the ice age.

That's a popular misconception, there have been periods of cooling also, it's all cyclic. However the huge burning of fossil fuels that has occurred since the industrial revolution has returned significant amounts of carbon, in the form of carbon dioxide, to the atmosphere.

This man made event has overtaken the cyclic warming and cooling of the planet and threatens to return us to the hot humid state which existed millions of years ago, when volcanoes spewed carbon dioxide and methane into the atmosphere. It was only the development of life forms which removed that carbon from the atmosphere and sequestered it into the ground as coal and oil, as those life forms died.

Since the start of the industrial revolution, the recovery and burning of that buried carbon, my mankind, has created the situation which, if left unchecked, will result in the end of life on this planet, as we know it today.

so what is happening now could be part of a cycle :-)

Unfortunately not, earth should be entering a cooling stage approaching a mini ice age at the moment, (if we look at past cycles) but the increase in carbon dioxide in the atmosphere has reversed that and instead the average temperature is increasing.

The term global warming cause confusion to some people because it does not follow that the weather will be warmer everywhere, even though the average temperature overall is higher. A better term is climate change due to there being more thermal energy in our atmosphere.

Approximately the same energy coming in from the sun, but due to greenhouse gasses, less energy going out. More energy in the atmosphere causes the average temperature to rise and causes the climate to change.

The result could be more and longer heatwaves in some areas, more and stronger storms in some areas, more rain causing floods in some areas perhaps that have not had any in the past, droughts in some areas that previously have had good rainfall, and ironically colder weather in other areas. All of these conflicting things are a result of climate change.

you don't that, do you. just propaganda from those who what to sell their expensive green devices that nobody will buy unless they made up some crisis.

Sorry, but I'm not going to get into an argument with you but my degree is in Science and I have studied the subject. Perhaps you should actually take a look at the science involved.

Short of going to University, a good starting place is https://www.noaa.gov/education/resou...change-impacts

I believe that whatever's happening with the planet's climate, what we humans are doing to "fix" it is likely to be doing more harm than good.
Governments are demanding money to throw at the problem with no clear cut, well-planned approach.
Wind farms are doing untold damage to the environment, especially to wildlife. Land based farm are killing birds by the thousands, if not millions and ocean based farms are killing marine life, including whales.
Solar farms are doing their part to compromise the environment and the animals trying to live in it.
The problem of what to do with the worn out parts from the wind generators...currently just being buried and hoping for the best...as well as the worn out/damage solar panels has not been satisfactorily solved. Then there's the approximately 60 gallons of oil each wind generator uses and must be changed regularly. What's happening to the used stuff?
Meanwhile, we have the technology to clean up the world's water, both fresh and salt, yet we drag our feet. It's estimated more than half of the worlds waste is dumped untreated into our fresh and salt water. Yes, even here in the oh-so-environmentally-conscious U.S, we're fouling our own water. Check out "untreated, raw sewage being dumped along the coast of New Jersey".
Millions of people have no access to clean water yet we do little to nothing except agonize over, and spend billions on the atmosphere.
Okay, that's my rant, over for the day.

Yes Miz, unfortunately there are a few downsides to addressing climate change, but the sad reality is, if we do nothing, the birds, fish, animals and humans will end up with an uninhabitable planet.

Example, consider Venus, second planet from the Sun, but the hottest in our solar system with an atmosphere of mainly Carbon dioxide.
