Do greenhouse gases really matter

DO GREENHOUSE GASES REALLY MATTER?

  • SOLAR HEAT SOURCE FOR PLANET EARTH

  • TEMPERATURE AND DISTANCE DETERMINES AVERAGE EARTH TEMP

  • EQUILIBRIUM TEMPERATURE IS ONLY -5 DEGREES F

  • APPLIES TO THE TOP OF THE ATMOSPHERE (CLOUD TOPS)

  • BLANKET OF GHG MAKES A 55 F DIFFERENCE!


Geologic carbon cycle major climate changes of the past

GEOLOGIC CARBON CYCLEMAJOR CLIMATE CHANGES OF THE PAST

  • SELF–REGULATING PROCESS

  • VOLCANOS EMIT CO2

  • WARMER MORE ACTIVE ATMOSPHERE – MORE STORMS AND RAIN

  • PACE OF EROSION INCREASES

  • MORE SEDIMENTS DEPOSITED IN SEAS

  • MORE CARBON BURIED IN SEA FLOOR

  • CYLE TAKES MILLIONS OF YEARS


But there s no real evidence

BUT THERE’S NO REAL EVIDENCE

  • WE HAVE ALL EXPERIENCED MAJOR GLOBAL WARMING – IT’S AN EVENT CALLED SUMMER

  • THE HUGE DIFFERENCE IS CAUSED BY A SMALL TILT OF THE EARTH’S AXIS

  • ICE AGES DRIVEN BY MINISCULE CHANGES IN EARTH ORBIT

    • EARTH ORBIT IS SLIGHTLY ELLIPTICAL (1-6%)

    • ICE AGE WHEN SUMMER IS AT LONG AXIS

    • INTERGLACIAL (TODAY) WHEN SUMMER AT SHORT AXIS

  • THESE SMALL CHANGES PRODUCE A MILE OF ICE OVER NEW YORK AND A DOUBLING OF FLORIDA THROUGH SEA LEVEL CHANGES


Climate change involves carbon

CLIMATE CHANGE INVOLVES CARBON

  • ICE AGE THEORY PROBLEM:

    • SOLAR CHANGE OPPOSITE IN HEMISPHERES

    • SOUTHERN GLACIERS SHOULD BE OUT OF PHASE

    • IN FACT THEY ARE IN ALMOST PERFECT PHASE

  • COLD SUMMERS IN CANADA INFLUENCE THE WHOLE WORLD

  • ARGENTINA FREEZES IN SPITE OF WARMER SUMMERS

  • A 90 PPM (<50%) CHANGE IN CO2 MADE THE DIFFERENCE


The basic facts

THE BASIC FACTS

  • CO2 WAS AT 280 PPM 150 YRS AGO

  • CO2 NOW AT 380 PPM (30% INCR)

  • PROBABLE 0.6 C (1.2 F) CHANGE NOW

  • CO2 LIKELY EXCEED 50% BY 2050

  • PAST 50% INCR ENDED ICE AGE

  • PARTICULATES MAY HAVE INITIALLY OFFSET HEATING

  • A NEW EXPERIMENT ON A VERY SENSITIVE SYSTEM

  • WE ARE SQUANDERING VALUABLE RESOURCES ALONG THE WAY


Carbon made simple

CARBON MADE SIMPLE

  • ATMOSPHERE 100 units

    • (Before 1700)

  • RESERVOIRS

    • Vegetation 70

    • Soil & litter 250

    • Fossil fuel 1000

    • Deep ocean 5000

  • EMISSIONS

    • Fossil fuel 0.75

    • Land use 0.25

  • DESTINATION

    • Atmosphere 0.40

    • Shallow ocean 0.25

    • Unknown 0.35


Wood for carbon storage

WOOD FOR CARBON STORAGE

  • TYPICAL NEW TEMPERATE FOREST STORES TON/ACRE/YEAR CARBON

  • CHESTNUT COULD INCREASE THAT BY 10-20% - FASTER GROWTH, BIGGER TREE

  • MILLIONS OF TONS FOR POWER/YR

  • MILLIONS OF ACRES OF FORMER FIELD NOW FORESTED IN EAST

  • ALBEDO AND TRANSPIRATION EFFECTS

  • TEMPERATE TREES MAKE A CONTRIBUTION BUT NOT THE ANSWER


Other side of carbon use mine reclamation

OTHER SIDE OF CARBON USE – MINE RECLAMATION

  • EASTERN COAL MINES ON PRIME CHESTNUT HABITAT

  • COMMON PRACTICE – REDUCE SLOPES, RECLAIM AS PASTURE

  • CHESTNUT BELONGS ON MINED LAND

    • THE NATURAL LAND COVER

    • ADAPTED FOR POOR SOILS ON ROCKY SLOPES

    • CAN SURVIVE DROUGHT AND LEACHING

    • CAPABLE OF RAPID GROWTH, RESPROUTING IF INJURED

    • WILDLIFE SUPPORT VIA NUTS AND BROWSE


Tacf now a partner in mine land reforestation

TACF NOW A PARTNER IN MINE LAND REFORESTATION

  • 1.3 MILLION ACRES OF LAND FOR RECLAMATION

  • MAJOR PORTION LEFT FROM PRE-LAW TIMES

  • CHESTNUT BELONGS ON THESE LANDS

  • MAJOR OPPORTUNITY FOR RE-INTRODUCTION OF CHESTNUT

  • DOES NOT IMPLY SUPPORT FOR MOUNTAIN-TOP REMOVAL

Reclamation background

RECLAMATION BACKGROUND

  • DRIVEN BY 1977 SMCRA LAW

  • DESIGNED TO STABILIZE LAND AND MINIMIZE EROSION

  • REGULATORS TRADITIONALLY EXPECT

    • SMOOTH AND COMPACTED SURFACE

    • DENSE GRASS AND LEGUME SOD

  • RECLAMATION REQUIRES

    • MECHANICAL COMPACTION

    • ABUNDANT SEED AND FERTILIZER

    • SEDIMENT CATCHMENT PONDS

  • FINAL PRODUCT BECOMES POOR PASTURE

    • FULL OF INVASIVE SHRUBS

    • HOSTILE TO TREE ESTABLISHMENT


Appalachian regional reforestation initiative

Arri is a partnership

ARRI is a Partnership


Goals of the initiative

GOALS OF THE INITIATIVE

  • Plant more high-value hardwood trees on reclaimed surface mined lands in Appalachia

  • Increase the survival rate of the planted trees

  • Increase growth rates and productivity from the surviving trees

  • Expedite the establishment of forest habitat through natural succession

    Where will trees grow on spoil

    WHERE WILL TREES GROW ON SPOIL?

    • IDENTIFY NATURAL FOREST ON DUMPED SPOIL

    • OPTIMAL GROWTH WHEN LOOSE SPOIL AT LEAST 4 FEET DEEP

    • DENSE TURF LIMITS TREE GROWTH

      • COMPETITION FOR LIGHT

      • COMPETITION FOR MOISTURE

      • ATTRACTION FOR RODENTS

    Fra reclamation forestry reclamation approach

    FRA RECLAMATION(FORESTRY RECLAMATION APPROACH)

    • STEP 1 – CREATE SUITABLE ROOTING MEDIUM (4 FEET OF “BEST AVAILABLE” MATERIAL)

    • STEP 2 – LOOSELY GRADE SPOIL TO CREATE NON-COMPACTED MEDIUM

    • STEP 3 – USE GROUND COVER CONSISTENT WITH TREE GROWTH (50% IDEAL)

    • STEP 4 – PLANT TWO TYPES OF TREES

      • EARLY SUCCESSION FOR COVER AND WILDLIFE

      • VALUABLE HARDWOOD TREES FOR TIMBER

    • STEP 5 – USE PROPER PLANTING METHODS (PROFESSIONAL PLANTERS)

    IMPORTANT ISSUES

    • TECHNICAL CHALLENGES

      • FLUSHING OF NUTRIENTS FROM COARSE SOIL

      • INNOCULATION - NATURAL BACTERIA, FUNGI

      • DROUGHT STRESS - COARSE SOIL SUBSTRATE

      • MANAGE SPREAD OF INK DISEASE

    • REGULATORY CULTURAL ENVIRONMENT

      • REGULATORS TO MODIFY RULES

      • INDUSTRY TO AVOID RELAXING COMPLIANCE

    • NEED TO FIT VARIABLE SITE CONDITIONS

      • DIFFERENT TERRAIN CONDITIONS

      • DIFFERENT CLIMATE AND SOIL PROPERTIES

      • DEVELOP “SYNTHETIC SOIL” RECIPES TO SUIT SITES

    • EMPHASIS ON COMMERCIAL TIMBER PRODUCTS

      • BUILT INTO REGULATORY “BEST USE” CONCEPT

      • DOWNPLAYS CULTURAL AND ECOLOGICAL VALUES

    • AVOID IMPLIED APPROVAL OF OTHER INDUSTRY PRACTICES


    Summary

    SUMMARY

    • CHESTNUT-DOMINATED FOREST BELONGS ON APPALACHIAN MINE SITES

    • MINE RECLAMATION A POTENTIAL PATHWAY TO GET CHESTNUT INTO THE FUTURE FOREST

    • MOST RELEVANT CARBON ISSUE FOR CHESTNUT IS REFORESTATION OF FORMER MINED LANDS

    • ARRI PROJECTS DEMONSTRATE THAT FOREST CAN BE RE-ESTABLISHED ON MINED LAND

    • ARRI PARTNERSHIP A NATURAL WEDDING OF TACF AND ENVIRONMENTAL INTERESTS
