I do comparative studies of climate evolution, and the interactions between planetary atmosphere and surfaces and their radiation environment, and try to understand the environmental factors that can affect a planet's habitability and how they change over time.
The planet isn't improvising, it's creating dynamic tensions between complex living systems in a planetary choreography, a balancing act between physical, chemical, biological, environmental, and human components.
If there's one vital, but underappreciated, subject in the conversation about climate change, it's waste: how to define it, how to create less of it, how to deal with it without adding more pollution to the planet or the atmosphere.
There is still significant uncertainty around all of the factors that affect climate change.
But no matter how big the effort to push a propaganda line might be, climate change is bigger. This, undoubtedly and regrettably, is the biggest immediate long-term environmental challenge we face. A failure to concretely come to some policy outcome on climate change has not only a negative environmental impact but also social and economic consequences for us.
Climates always change. The question is, how are we going to adapt to climate change? Now, it may be true that we are accelerating it inadvertently by messing with our atmosphere, but regardless of that, the climate will change.
Radiation is one of the important factors in evolution. It causes mutation, and some level of mutation is actually good for evolution.
Climate change and energy use are global problems - News Corp is a global company. Our operations affect the environment all over the world.
Climate has always changed. It always has and always will. Sea level has always changed. Ice sheets come and go. Life always changes. Extinctions of life are normal. Planet Earth is dynamic and evolving. Climate changes are cyclical and random. Through the eyes of a geologist, I would be really concerned if there were no change to Earth over time. In the light of large rapid natural climate changes, just how much do humans really change climate?
We're taking climate change seriously. But it's not the only environmental issue that we face as a planet.
Climate scientists think of nothing but climate and then express their concerns in terms of constructs such as global mean surface temperature. But we live in a world in which all sorts of change is happening all the time, and the only way to understand what climate change will bring is to tell stories about how it manifests in people's lives.
It could be the case that all the studies supporting a warming planet are wrong; science always leaves that door open, but anthropogenic climate change remains the best explanation for a mountain of data that scientists have been poring over for a century.
Real change will only happen when we fall in love with our planet. Only love can show us how to live in harmony with nature and with each other and save us from the devastating effects of environmental destruction and climate change
All the things that human beings suffer from are how their environment treats them, and how the elements of their planet affects their mind and body - like radiation, cancer, and all.

Now, humans have become a dominant force of planetary change and, thus, we may have entered an eon of post-biological evolution in which cognitive systems have gained a powerful influence on the planet.
The evaluative habits developed in sibling interactions undoubtedly affect the salience and choice of comparative referents in self-ability evaluations in later life
