Climate change portrayed as the problem of increased atmospheric concentrations of carbon dioxide

Atmospheric concentrations of carbon dioxide have varied radically throughout earth's history

More extreme concentrations will follow after the industrial revolution caused concentrations to shoot up, 30% increase since industrial revolution

1997, group of scientists calculated between one-third and one-half of the earth's and surface has been transformed by human action.

More than half of all accessible freshwater has been appropriated by humanity. We live on a human dominated planet

As a result of the increasing human domination of the planet, scientists have proposed we live in a new geological era the Anthropocene. We need to find a way to live in this.

People feel they can do little to prevent global warming. Climate friendly acts are not enough. Morally required that we get governments to do their jobs to prevent the disaster of excessive global warming

Models for collective responsibility- cumulative model- every relevant input produces a relevant output. Second model is he threshold model in which no effect occurs unless a specific level of collective contribution is achieved, a particular threshold is reached

The cumulative effect doesn't happen, individual emissions do not stack up, overflow the atmosphere and cause damages. Molecules are influenced by feedback's and fluxes =, may be absorbed by the oceans

Threshold model is more applicable- thresholds do exist. However this does not capture the dynamic nature of the climate system- the system at each level is open to influences

Instead of green consumerism where individual acts have an impact on climate change, different things we can do to make a difference in the world, we can further adaptation and compensate those who suffer from the effects of climate change, making sure at a macro-level, they are both fair and effective

The balance between what is world affecting and self-affecting is important in determining life's meaning.

We associate life's meaning with successfully achieving goals. We think of a meaningful life as something that is good, making a difference in the world

The idea that is it success, fame, or celebrity that makes life worth living is an instance of a more general view

Life worth living is based on the attitudes or approval of others vs the idea that a life worth living is primarily internal to each person. Life presents itself as a field of choice, decision, and action rather than a set of imperatives required for survival.

In my view, we find meaning in our lives in the context of relationships to other humans, animals, the rest of nature. This involves balancing goods, such as self-expression, responsibility to others, joyfulness, commitment, attunment to reality and openness to new experiences. What i am responsible for it trying to make the world better

Ethics primarily concerned with the proximate, need to look into the remote , expanding circle of ethics made proximate through new living arrangements, forms of travel, new forms of imagery via technological innovation

However, not everything can be made proximate to creatures like us

Ethics leaves its mark on the world because it requires attunement to reality, make the world better and enable us to live meaningful lives

Virtues provide the motivation to act in our various roles to reduce GHG emissions and ameliorate their effects

Green values as part of an ethics for the Anthropocene . Three categories: those that reflect existing values, draw on existing values, those that reflect new values- preservation, rehabilitation and creation

Hill 1983- Preservation- shared ideal of humility should lead people to a love of nature , would not destroy forests

Temperance may be a good target for rehabilitation- self restraint and moderation- as a green virtue that emphasises the importance of reducing consumption

Mindfullness- appreciating the consequences of our actions that are remote in time and space
