Real
science is actual observation and not computer modeling. City smog, haze etc.
does not go above a few hundred feet, kept buoyant in daylight hours by heat
from the ground.
This lake and sky at Glenorchy, New Zealand, will probably still look like this long after man has left the planet.
You
can look down on Auckland, New Zealand, smog from the summit of Mt Atkinson in Titirangi.
The
amount of CO2 in the air is always 38 parts in 100,000, and CO2 is not an
impurity. Thousands of tons of water free of impurities are lifted each day
from the oceans by evaporation.
A low pressure system can range hundreds of miles and drop rain over an area as vast as the Tasman Sea.

The
amount of soot particles from industry and emissions from a city is
infinitesimal, heavier than air and can not possibly contribute to weather. The
weather always gets there first, then deals to the steam or fumes, not vice
versa.
Water vapor rises because it is lighter and less dense. Look out of a Boeing window and you will see, like white candy floss, streaky ice crystal cirrus cloud above you at 50,000 feet. Yet it is where a wet weather system begins.

The
ice gathers and gets heavier then descends to form rain clouds which drop as
downpours.
CO2 comes out of volcanoes, ejected by volcanic blasts often 14kms into the air then kept aloft by thermals and upper-level turbulence. Being heavier than air the CO2 eventually drops back to the ocean where it dissolves.
To suggest soot changes weather patterns is to deny the enormity of the weather systems and to magnify out of all scientific proportion Man's tiny contribution.

There
is no evidence that man-made pollution contributes more to soot levels in air
than gets there through natural forest and bush fires and eruptions from
volcanic sources.
The Taupo eruption and Pinatubo may have had slight momentary effect, but would have dissipated very rapidly. Temperature records from before, during and after the Pinatubo eruption show hardly any deviation.
Droplets of rain form around dust particles, which is why your windscreen needs cleaning after a shower. 100 years ago it was never imagined that soot might alter world weather when London, Paris, Chicago, Shanghai etc. had pea-soup fogs.
Cities are now much cleaner than in the past, even in China despite coal widely burnt. Of course it is not pleasant to breathe it, and we can always do more to create cleaner habitats. But that would be costly.

With
no production return no one will foot that bill.
In the debate about world weather we tend to forget that rain is quite local. In Wellington we do not get rain that has travelled from Nebraska. It comes from the harbor or nearby coasts.

The
cycle of evaporation to rain is about 5-7 days. Average wind speeds are no
greater than 15 mph, or 2,500 miles per week, which is not even the width of
China (3,123 miles).
In a week a low pressure system has all but dissipated. To slow it even more, rain-laden clouds become stationary.

Considering
that after 7 days most atmospheric soot would have separated out, loads of soot
could not travel beyond Chinese borders in appreciable amounts and with significant
effect. Therefore any pollution by China is not a global problem
Emissions are mostly dirty steam. The 99% part that is water vapor joins the sky as extra cloud. The dirt in fuel that provides the blackish look falls to ground and is biodegradable.

It
is not healthy to inhale it, but breathing any smoke is not good for you,
especially the carcinogenic fumes from barbecued sausages, yet no one is saying
sausages are wrecking the planet.
Given the vastness of the atmosphere and the high altitude at which weather begins vs the tiny amount of city smog that only rises a few hundred feet by day then falls again to ground under its own weight at night, it is impossible that weather could ever be affected by emission impurities.
Remember too that NZ weather comes from thousands of miles across the ocean, either under the Great Australian Bight, up from the Southern Ocean’s icy polar waters or down from the Coral Sea via the Queensland coast - all vast ocean areas with no factories or cars.
No matter how much impurity is put into the air, it is from the earth and has a natural source.

None
comes in from outer space. No matter how polluting we are, and how much we mess
our own environment, 99% of all species, including Man will perish through natural
evolution long before the planet is affected.
The choice to live in cities, near emissions, is always ours.

We
go to work and need to drive to get there. We need supermarkets for food and
they need trucks and highways to keep shelves stocked. Pollution is inevitable.
The Chinese do realize that there is a pollution problem to be fixed.

But
it is a local problem for them only, and only affects us if we choose to go
there as tourists or as athletes.
Their
dirty air may dismay sightseers but it will not destroy Planet Earth. Climate
and the earth were here first, and then we all came along. Climate and the
earth will still be here when we are all gone
Peter’s Comment
For
once I have to agree with some of the points made by Ken Ring. Ring publishes a New Zealand weather forecast book each year and almost claims that he can predict
which side of the street will get rain this time next year.
In
the overall scheme of things man and his activities are so insignificant that
they pose no more of a threat to the planet than a single ant nest could have
on world honey production.
Many
of the things that people believe about climate and the planet are alarmist and
based on false assumptions. For example the jet trails in the sky that are a
familiar sight all over the world are not caused by unburned fuel as is
commonly believed.
Jet
trails are the result of air flow around the aircraft’s wing-tips as the air
pressure below the wing tries to equalize with the pressure above. That leads
to a trailing cork-screw of air in which the air pressure and temperature drops
causing water vapor to condense and form a cloud that has exactly the same
composition as any other cloud.
The
only connection between wing-tip vortices and fuel is that the vortices cause
drag and increase fuel consumption. Airline manufacturers have countered the
wing-tip drag by introducing winglets on the ends of the wings.
‘But
what about the wholesale loss of trees all over the world?’ you ask. ‘Surely
that must be affecting climate?’
Anyone
who is in any doubt about the trees can get their own absolute proof and truth
by going on Google Earth and zooming in on the Amazon Basin. It is all there
for the whole world to see – the Amazon Basin still has about 99% of its trees.
Meanwhile there are other areas that grow commercial trees where previously no
trees grew. In addition, the last hundred years has seen an explosion of
ornamental trees, parks and gardens.
People
should not believe everything they are told at protest marches or in viral
emails.
