There are some things we know with certainty and other things that are still being researched. We do know that we are in an interglacial period. We also know that anthropogenic CO2 increases have taken place and, from radiative transfer considerations, will contribute to some warming. We also suspect that anthropogenic CO2 increases are not, by themselves, enough to cause enough warming to be of concern. Any direct warming from anthropogenic CO2 increases must be accompanied by positive feedbacks that cause additional warming - an amplification if you will. For example, additional CO2 causes warming which increases the amount of water vapor in the air which causes additional warming since water vapor is a greenhouse gas. There can also be negative feedbacks. The additional warming causes additional water vapor that results in more clouds that reflect solar radiation which can cause cooling. Of course, the clouds also intercept terrestrial radiation and reemit it back down to earth causing more warming. It's complicated. The dire forecasts you hear about come from coupled ocean/land/atmospheric models which attempt to simulate where the climate will drift to when CO2 levels are increased. Retrospective model runs have had issues with reproducing mid-tropospheric temperatures in the tropics (yes, that is important) and this raises questions about their fidelity and appropriateness as a tool for developing public policy. It is just down right difficult to model complex, non-linear interactions that are not completely understood such as cloud/radiation interactions (which are critical to getting the feedbacks correct and without positive feedbacks we probably don't have an issue).
Essentially the bottom line is we don't know how much warming will take place in the future from man's activities. With the homogenization of surface data, I have doubts whether we really know how much recent warming is the direct result of man's activities. This is still an area of research. We do know that the climate will continue to drift from natural causes such as the Milankovitch Cycles. We do know that CO2 levels will continue to increase for the next several decades as developing nations will continue to generate power from fossil fuels. Put solar panels on your house because it saves you money and makes you feel good but it won't have any impact. Whether you drive a gas or electric golf cart won't have any impact either. I do plan on buying a Tesla because they are pretty cool. On thing that I do find rather amusing is whenever anyone says they are "trying to save the planet". The planet is fine. The human race might be another issue. If mankind goes extinct the planet will erase all remnants of the human race within a few million years. Quote:

That too. In my experience with Communism, their main interest concerns the wealth of the party members. And the absolute control of the masses.
But China is changing, a family member was responsible for educational technical exchange between our countries at university level in certain Chinese provinces. China is showing growing pains. They are very intelligent people soon, I expect they may be leading the charge for the environment. Last edited by Velvet; 10-14-2019 at 05:15 PM. |

The unfortunate part of the whole subject is so much amplification by the media of these groups positions and are presented as if we do not accept/believe/do what they are "selling"....the planet is doomed. Centuries of climate change radical swings point to the contrary. |

It's a cycle people. About 26,000 years in length. The Earth is still recovering from the last Ice Age. Unfortunately, for us, there was a much, much, much smaller human population back at the end of the prior Ice Age, therefore we have no real proof what will happen, only that humans cannot control the warming trend. PERIOD!

Did the studies also consider the effect of sulphuric dioxide from the volcanoes and other gases as well? And the thermal effects of the lava? I’ve been following the latest eruption of the Kilauea volcano on the Big Island in Hawaii and the type of damage it contributed to the atmosphere.

Well, when you live right by a volcanoes like Hana on Maui, or Kilauea on the Big Island and you breathe in The Vog (volcanic fog) and cry and sneeze and have difficulty breathing regularly, and see the devastation and extension of the plant life killed off by sulphur dioxide, and the island reshaped by the lava. When you see the power of the earth in its original raw form, some call it the goddess Pele, then you develop a certain respect, perhaps even an understanding even if you are a scientist....

I'd rather research, and then see if we're going to do anything about it. Glad TV land is building those green houses for hydroponics.

A volcano erupting as Krakatoa did in 1883 will change climate dramatically for years to come.
Global climate[edit] In the year following the 1883 Krakatoa eruption, average Northern Hemisphere summer temperatures fell by as much as 1.2 °C (2.2 °F).[12] Weather patterns continued to be chaotic for years, and temperatures did not return to normal until 1888.[12] The record rainfall that hit Southern California during the water year from July 1883 to June 1884 – Los Angeles received 38.18 inches (969.8 mm) and San Diego 25.97 inches (659.6 mm)[13] – has been attributed to the Krakatoa eruption.[14] There was no El Niño during that period as is normal when heavy rain occurs in Southern California,[15] but many scientists doubt that there was a causal relationship.[16] The Krakatoa eruption injected an unusually large amount of sulfur dioxide (SO2) gas high into the stratosphere, which was subsequently transported by high-level winds all over the planet. This led to a global increase in sulfuric acid (H2SO4) concentration in high-level cirrus clouds. The resulting increase in cloud reflectivity (or albedo) reflected more incoming light from the sun than usual, and cooled the entire planet until the suspended sulfur fell to the ground as acid precipitation.[17] Global optical effects[edit] 1888 paintings, showcasing the optical effects of the eruption on the sky over time The 1883 Krakatoa eruption darkened the sky worldwide for years afterwards and produced spectacular sunsets throughout the world for many months. British artist William Ashcroft made thousands of colour sketches of the red sunsets halfway around the world from Krakatoa in the years after the eruption. The ash caused "such vivid red sunsets that fire engines were called out in New York, Poughkeepsie, and New Haven to quench the apparent conflagration."[18] This eruption also produced a Bishop's Ring around the sun by day, and a volcanic purple light at twilight. In 2004, an astronomer proposed the idea that the red sky shown in Edvard Munch's famous 1893 painting The Scream is also an accurate depiction of the sky over Norway after the eruption.[19] Weather watchers of the time tracked and mapped the effects on the sky. They labeled the phenomenon the "equatorial smoke stream".[20] This was the first identification of what is known today as the jet stream.[21] For several years following the eruption, it was reported that the moon appeared to be blue and sometimes green. This was because some of the ash clouds were filled with particles about 1 µm wide – the right size to strongly scatter red light, while allowing other colors to pass. White moonbeams shining through the clouds emerged blue, and sometimes green. People also saw lavender suns and, for the first time, recorded noctilucent clouds.[18] from: 1883 eruption of Krakatoa - Wikipedia

Lots of people will be finding all kinds of wild critters in their front yards, if this continues. Those critters have to live SOMEWHERE and if you take away their homes, they'll just start parking in yours. This is the only planet we are able to occupy right now. We lack the technology to occupy any other. It's in our best interest to take care of it. Don't worry so much about China - which has made great strides in improvement. Worry about yourself, your neighbors, your city, your state, and your country. What are YOU doing to reduce our impact on pollution and the changing climate? |

Have you ever heard the story about Chicken Little? As to the original question, no I have no worries of climate change. If you go back and research all the predictions of doom, gloom and death from climate change humans were supposed to be dead already. My reading has shown there have been at least 5 ice ages and the climate warmed up after each one. During many of those ice ages man didn't exist so what caused the climate change? Greenland was settled for a while by the Norsemen and the name was given to the land because it was green and fertile. Then it became colder and snow covered so the Norse fled their settlements and it is still covered with snow.
