Climate Change The Other Theories!
2Summary of Past CSTRs
- January 1998 Focus on Kyoto Implications
- Kyoto Agreement based on one theory and few solid
facts - Prudent to move ahead on GHG reductions but
cautiously - May 2000 Focus on Other Theories
- Seven theories proposed
- In trouble-shooting the first cause considered is
not always right. Maybe a number of causes. GHG
looks weak. - February 2002 Focus What is the best Theory?
- Better data now, what theories can be eliminated?
- What theory is best supported by the data
3Climate Change is Occurring
- Evidence is growing that the Climate is Changing
- the balance of evidence suggests a discernible
human influence on global climate being
confirmed - Climate Changes appear to be mainly local and
regional rather than global - Most change is being observed in the Northern
Hemisphere
4What is Causing the Climate Change?
- What is the latest data?
- IPCC Science Working Group Technical Summary
- How do the theories stack up against the data?
- What theories eliminated or reduced?
- Of the remaining theories which is more strongly
supported? - What are the implications?
5Latest Data Indicates
- Globally atmospheric GHGs are up.
- Large unexplained CO2 sink in North America
reported - Globally average temperatures are higher
- Northern Hemisphere higher especially last 10
years - Night-time lows increasing more than day-time
highs - More over land than over oceans. Cooling in some
areas. - Growing Season Increase by 1 to 4 days per
decade in northern hemisphere
6Latest Data Indicates
- Precipitation increases (5-10) over most land
areas in mid to high latitudes of Northern
Hemisphere - No observed increase in southern hemisphere
- Correlated to increases in clouds and extreme
weather. - Heavy precipitation events increased in northern
latitudes - Likely a 2 to 4 increase in the frequency of
heavy precipitation events in last 50 years in
Northern Hemisphere
7Latest Data Indicates
- Atmospheric Water Vapour Increased in Northern
Hemisphere by several percent per decade - Cloud cover in Northern Hemisphere increased by
2 - Positively correlated with decrease in diurnal
temperature range
8Latest Data Indicates
- Sea-Ice in Northern Hemisphere decreasing
- No trends in Antarctic sea ice apparent.
- Non-polar glaciers Widespread retreat except in
coastal areas. - El Nino Events More frequent, persistent and
intense over the last 30 years. - Coral bleaching Increased esp. during El Nino.
- No acceleration in sea level rise detected over
last century
9Seven Climate Change Views
- Warming is Not Happening
- Real Problem is Waste of Fossil Fuels
- GHGs Trapping Solar Radiation
- Energy Use Warming Atmosphere
- Human Impact Minor or Beneficial
- Cant Afford the Solutions
- Water Emissions - Main Climate Change Driver
10Warming Not Happening?
Likely
High Uncertainty
11Waste of Fossil Fuels
- Should be a real concern.
- Even coal wouldnt last for ever.
- A good reason on its own to reduce fossil fuel
use. - Much of the use is for status or convenience not
need. - Root problem is societal. Live for today
attitude
12GHGs Trapping Solar Radiation
- Should be happening and increasing
- Experts cant agree on how much it contributes
- Models force fit to history with scaling factors
and adjustments and used to forecast, but still
dont model clouds, land-use or other human
factors. - GHG must be global yet much of the data only
shows changes in Northern Hemisphere
13Energy Use Warming Atmosphere
- Total anthropogenic energy generation is about
550 ExaJoules/yr enough to warm atmosphere 1
degree C per year. - Most energy is turned into heat and reradiated,
so would not build up enough. - Some turned into water vapour
- Combustion or from Cooling Towers.
- Summary not a major impact.
14Human Impact Minor or Beneficial
- Growing evidence that it is not minor and that it
has been rapidly growing in the last 30-50 years. - Cost vs. Benefits tough to balance
- More growing days and warmer north
- More severe storms, loss of natural habitat
- Increases in severity where losses are greatest
in people, property or sensitive environments
15Cant Afford the Solutions?
- Depends on the cost of the problems and on what
needs to be solved. - Many energy reductions are very cost effective
and have other benefits - Reducing energy use is the most cost effective
solution and most likely to reduce human impacts
on climate no matter what the major cause is.

19Water Emission Calculations
- Energy to Atmosphere
- 9000 x 109 GJ/yr (exajoules/yr)
- 15-20 times human energy use!
- Water to Atmosphere (mainly in Northern
Hemisphere) - 4,000 Gt/yr
- -10 of Surface flow to oceans
- 5 of Land Evaporation
20What Goes Up, Must Come Down
- Water Added to Atmosphere Must Come Out
- 5 of increase in net land evaporation matches
5-10 increase in precipitation over land - Water added in Northern Hemisphere, comes out in
Northern Hemisphere after forming clouds - When water condenses, heat is liberated
- Condensation in coldest areas so they warm the
most. - Energy ? melts ice, warms air water
21The Heat Pipe Effect
Day/Night Cycles
Water gives Up Heat and Falls In Cold Areas
Water Transport
Water added in Hot Dry Areas
22How Does This Theory Fit the Facts?
- Source is anthropogenic and increasing
- Should cause increased warming in cold areas but
relatively little effect in temperatures
elsewhere. - Should cause increased rainfall and increase
severity of storms ? Unusual patterns - Increases night time low temperatures due to
day/night cycling as dew point is raised
23Water Impacts
- Two thirds of global water use is for irrigation.
Almost all in Northern Hemisphere - Most of the rest for industry in same region
- Four countries account for half the worlds 670
million acres of irrigated cropland - Over 60 of the water added doesnt reach the
plants - Also tend to be located near or could affect
areas experiencing the largest effects of climate
change

27Summary for Water Vapour
- Water is an important climate change factor
- Source of water and energy for weather
- A 5 increase in land evaporation due to human
water use should be a concern - Higher water evaporation from dry areas (i.e.
southern California) more likely to cause unusual
weather patterns. - Water is the immediate concern and problem.
Climate change and water shortages/surpluses
causing human/environmental disasters.
28Water Implications
- Improvements in irrigation practices may be more
important than GHG reductions - Reduce wasteful irrigation methods
- Select crops that suit the local climate
- These changes could be made with a fraction of
the expenditures for GHG mitigation. - Focus on the Agriculture Industry
- Many responses to GHG theory proposed make water
situation worse - Dams, water transfers south, biomass energy,
nuclear power
29The Balance of Evidence - Says...
- Human Enhanced Water Evaporation SHOULD BE THE
major factor in Climate Change Equation - GHG impacts may still be a concern and are an
indicator of energy waste so should still be
reduced by reducing energy use - Finding the right solutions means addressing the
right problem.
30Does It Matter Which Theory is Right?
- Likely no theory is entirely right.
- Best strategy is to find Robust Solutions
which - Minimize Water added to atmosphere
- Reduce Energy Waste ? Fossil Fuel Consumption ?
Reduce GHG emissions - Create Wealth (improve standard of living)
31New Paradigms? Not Really
- Sustainable Development is based on
- Reduce
- Waste of energy, water and other resources on
trivial wants so they are there when future
generations need them. - Reuse Resources more than once
- Recycle If you cant do the first two.
- Replace Feel good placebo in last place.
Wasting Renewable Power is still a waste of
resources - Is it really green?
32Summary of Our Choices
- We have the ability to choose our responses
- We should make the choices proactively
- We should ensure the right actions are taken
rather than the politically correct or expedient
ones. - There is more to life than increasing its
speed. - Mahatma Ghandi
33Discussion and Challenges
- What adds up and what should we do about it?
- What is missing?
- What next?
