GHGs
Projections this will continue
“Cumulative emissions of CO2 largely determine global mean surface warming by the late 21st century and beyond (see Figure SPM.10). Most aspects of climate change will persist for many centuries even if emissions of CO2 are stopped. This represents a substantial multi-century climate change commitment created by past, present and future emissions of CO2.”

GHGs
With disruptions
Do we care?
All of what you have seen is well and good but the issue is do we as a society do something about this?
In the late 1990s we chose not to undertake action because “more science” was needed
In 2001 we did not join Kyoto because it was “too expensive” and did not cover all emitters
So should we take action?
Economically action is justified when the benefits of taking action on the margin exceed the costs of that action
Wait for more information –do little and live with it
Plan to adapt
Try to reduce future changeMitigate emissions
Policy Alternatives
Defining some terms
Impacts or effectsImpacts: Effects on natural and human systems. In this report, the term impacts is used primarily to refer to the effects on natural and human systems of extreme weather and climate events and of climate change. Impacts generally refer to effects on lives, livelihoods, health, ecosystems, economies, societies, cultures, services, and infrastructure due to the interaction of climate changes or hazardous climate events occurring within a specific time period and the vulnerability of an exposed society or system. Impacts are also referred to as consequences and outcomes. The impacts of climate change on geophysical systems, including floods, droughts, nd sea level rise, are a subset of impacts called physical impacts.
Vulnerability: The propensity or predisposition to be adversely affected. Vulnerability encompasses a variety of concepts and elements including sensitivity or susceptibility to harm and lack of capacity to cope and adapt.
Emissions
Anthropogenic emissions Emissions of greenhouse gases, aerosols, and precursors of a greenhouse gas or aerosol caused by human activities. These activities include the burning of fossil fuels, deforestation, land use changes, livestock production, fertilization, waste management, and industrial processes.
GHGsGreenhouse gas (GHG) Greenhouse gases are those gaseous constituents of the atmosphere, both natural and anthropogenic, that absorb and emit radiation at specific wavelengths within the spectrum of terrestrial radiation emitted by the Earth’s surface, the atmosphere itself, and by clouds. This property causes the greenhouse effect. Water vapour (H2O), carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4) and ozone (O3) are the primary greenhouse gases in the Earth’s atmosphere. Moreover, there are a number of entirely human-made greenhouse gases in the atmosphere, such as the halocarbons and other chlorine- and bromine-containing substances, dealt with under the Montreal Protocol. Beside CO2, N2O and CH4, the Kyoto Protocol deals with the greenhouse gases sulphur hexafluoride (SF6), hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs).
GWPGlobal Warming Potential (GWP)An index, based on radiative properties of greenhouse gases, measuring the radiative forcing following a pulse emission of a unit mass of a given greenhouse gas in the present-day atmosphere integrated over a chosen time horizon, relative to that of carbon dioxide.
The GWP represents the combined effect of the differing times these gases remain in the atmosphere and their relative effectiveness in causing radiative forcing. The Kyoto Protocol is based on GWPs from pulse emissions over a 100-year time frame. As for the Kyoto Protocol, this report uses GWP values derived from the IPCC Second Assessment Report: 21 for methane (CH4), 310 for nitrous dioxide (N2O), 1,300-11,700 for hydrofluorocarbons (HFCs), 6500-9200 for perfluorocarbons (PFCs), and 23,900 for sulphurhexafluoride (SF6).
Mitigation
Mitigation (of climate change) (from IPCC WGIII Glossary)
A human intervention to reduce the sources or enhance the sinks of greenhouse gases. This report also assesses human interventions to reduce the sources of other substances which may contribute directly or indirectly to limiting climate change, including, for example, the reduction of particulate matter emissions that can directly alter the radiation balance (e.g., black carbon) or measures that control emissions of carbon monoxide, nitrogen oxides, Volatile Organic Compounds and other pollutants that can alter the concentration of tropospheric ozone which has an indirect effect on the climate.
AdaptationAdaptation (to climate change) (from IPCC WGII Glossary)
The process of adjustment to actual or expected climate and its effects. In human systems, adaptation seeks to moderate or avoid harm or exploit beneficial opportunities. In some natural systems, human intervention may facilitate adjustment to expected climate and its effects.
Incremental adaptation Adaptation actions where the centralaim is to maintain the essence and integrity of a system or process at a given scale.Transformational adaptation Adaptation that changes thefundamental attributes of a system in response to climate and its effects.
So what can we do
So What could we do?
Reactions to climate change basically consist of four directions: • Live with the effects – do little• Reduce future extent by limiting GHG net emissions - Mitigation• Alter the way we do things adapting so as to reduce the impact of
change - Adaptation• Monitor what is happening- Information
Last three compete with traditional investment

• Inevitability of adaptation• Likely need adaptation and monitoring • Attention to mitigation as we grow
Policy Challenge• Most effects in future
• Mitigation and adaptation costs now
• Exact nature of effects and effectiveness of adaptation and mitigation are uncertain + controversial
• Unilateral action on mitigation not effective but collective no action means nothing gets done
• Resource and investment competition between current production/R&D and needs for mitigation/adaptation
So grand challenge is
How much to invest now in mitigation and adaptation in interest of future parties at likely cost of current?
So what is the Economic issueExternality is the uncompensated impact of one group’s actions on the well-being of bystanders.
If effect on bystanders is adverse, a negative externality.If effect is beneficial, a positive externality.
Fossil fuel emissions can be a negative externality.
Market failure Because buyers and sellers neglect the external effects of their actions when deciding how much to demand or supply, the market equilibrium is not efficient when there are externalities.
Income distribution - who gains/ who loses and where – high vs low latitudes
Intergenerational equity -- Bystanders are those damaged by warmer climate now and in future
Co-benefits some actions that can be undertaken also clean up air and water and enhance farm incomes and damage trade. How do we consider
Policy issue - Do we act now to benefit those in future

Why is this happening?
IPCC (1995) “The balance of evidence suggests a discernible human influence on global climate.”
IPCC (2001) “Most of the warming of the past 50 years is likely (>66%) to be attributable to human activities.”
IPCC (2007) ”Most of the observed increase in global average temperatures since the mid-20th century is very likely (>90%) due to the observed increase in anthropogenic (human caused) greenhouse gas concentrations.”
IPCC (2013) It is extremely likely (95–100% probability) that human activities caused more than half of the observed increase in global average surface temperature from 1951 to 2010.
Why are we seeing climate change?
Source : U.S. National Assessment/ http://www.usgcrp.gov/usgcrp/Library/nationalassessment/images/Greenhouse-s.jpg.
Some gases, like carbon dioxide (CO), trap heat in the atmosphere by absorbing longwave radiation while letting the Sun's energy pass through. The transparent roof and walls of a greenhouse allow in the sunlight while keeping in the heat. Since these gases act similarly in the atmosphere, we call them greenhouse gases.

If small glaciers and polar ice caps on the margins of Greenland and the Antarctic Peninsula melt, the projected rise in sea level will be around 0.5 m.
Melting of the Greenland ice sheet would produce 7.2 m of sea-level rise
Melting of the Antarctic ice sheet would produce 61.1 m of sea level rise.

• Very likely that heat waves will be more intense, more frequent and longer lasting
• Precipitation generally increases but with general decreases in the subtropics
• Precipitation intensity is projected to increase but there would be longer periods between rainfall events.
• Tendency for drying of mid-continent during summer, indicating a greater risk of droughts in those regions.
• Sea level projected to rise 1999 and 2099 by 0.18 to 0.59 m.• Likely increase in hurricane peak wind intensities - an
increase in the numbers of the most intense.• Fewer mid-latitude storms- poleward shift of storm tracks• Atlantic Ocean Meridional Overturning Circulation (MOC)

Degree of climate change - What is projected
Current developments are disruptive of some activities
Projections on water, temperature, severe weather and hurricanes are worrisome for agriculture and other sectors. Sea level also.
Possibility of Mitigating emissions will influence electricity generation and petroleum industries that are large in Texas.

“Stabilization”: 1 ton CO2/yr per capita
It is not sufficient to limit emissions in the prosperous parts of the world and allow the less fortunate to catch up. Such an outcome would overwhelm the planet.
The emissions of the future rich must eventually equal the emissions of today’s poor, …

Why Adapt
Types of Adaptation Actions
Adaptation can be “natural” or “autonomous” or “planned.”
Natural adaptations are actions in ecosystem stimulated by species reacting to climateAutonomous adaptations are actions taken voluntarily by decision-makers (such as farmers or city leaders)Planned adaptations are interventions by governments to address needs judged unlikely to be met by autonomous actions
Public sector may play important roles in all cases.• Support autonomous adaptation by providing information,
shaping market conditions and developing technologies• Act directly by developing strategies, providing resources, and
carrying out projects (infrastructure development).• Influence natural adaptation by managing the unmanaged
Agrilife scientists are in the public sector group
