Thus far, Kepler has found 48 planetary candidates in their host star's habitable zone (of which 10 are near Earth - size), but this number is a decrease from the 54 reported in February 2011 only because the Kepler team is now applying a stricter definition of what constitutes a habitable zone around stars to account for the warming effect of planetary atmospheres, which would move such a zone away from the star, outwards in orbital distance resulting in longer orbital periods (NASA news release; and Kepler Press Conference slides — in pdf).
In the current era in which the problems of global warming can lead to planetary catastrophe, every city has to have a plan for adapting to climate change, especially thosesubject toextreme events.
If human - induced global warming, among other factors such as human - driven pollution and human - forced overpopulation, serve decisively to precipitate the massive extinction of biodiversity, the irreversible degradation of Earth's environment and the reckless dissipation of its resources, so as to make our planetary home unfit for life as we know it, then is no one to bear responsibility for such a colossal wreckage as we could help to perpetrate in these early years of Century XXI?
It is as useful for global warming as sending a man (or woman) to mars is for planetary science.
ENSO merely reflects a state of flux for the entire planetary climate system, of which La - Nina cools and El - Nino warms, but overall the temperature of the atmosphere is warming.
The argument for geoengineering goes like this: the world is getting inexorably warmer; governments show no sign of drastically reducing greenhouse gas emissions, so why not control the planetary thermostat by finding a way to filter, block, absorb or reflect some of the sunlight hitting the Earth?
It turned out things were far more nuanced (as he later said, «The Earth system may be less responsive in the warm times than it was in the cold times»), but in a field that had long mainly foreseen smooth curves for planetary change with rising greenhouse gas levels, the result was a vital focus on the risks of abrupt climate change.
This implies that the CRF levels must have systematically decreased over time, causing a long - term decrease in the low cloud fraction and hence a long - term reduction in the planetary albedo, that again would be responsible for the warming.
The newest paper, in the current issue of Science, «Varying planetary heat sink led to global - warming slowdown and acceleration,» argues that the Atlantic not only has shaped the current plateau, but also was responsible for half of the sharp global warming at the end of the 20th century.
Consider the quasi-official global goal (codified, for example, in the Copenhagen Accord) to hold total planetary warming to 2 °C (Earth surface average) above pre-industrial levels.
If global warming is really a planetary emergency, why won't he deliver the same talk for $ 50,000?
However... this is no surprise, as slow warming has been the planetary theme for 300 years or so.

Variations in how the Earth is tilted and its orbit around the sun make for a pattern of planetary warming phases followed by cooling phases across the millennia.
The high reflectivity of this new planetary layer, the Lucrosphere, will radically incease our planet's albedo, and so compensate for the loss of reflective Arctic sea ice that threatens to accelerate global warming.
The key science question for citizens and their representatives is not whether most recent warming is man - made but whether climate change, as Al Gore HAS put it, is a «planetary emergency... that threatens the survival of civilization and the habitability of the Earth.»
The interglacial and the glacial planetary temperature data shows cycles of warming and cooling interrupted by very strong «RCEs» (Rickies) Rapid Climatic Change Events (For example the Younger Dryas abrupt cooling event and the termination of the last interglacial).
«Assessing recent warming using instrumentally homogeneous sea surface temperature records» «Tracking ocean heat uptake during the surface warming hiatus» «A review of global ocean temperature observations: Implications for ocean heat content estimates and climate change» «Unabated planetary warming and its ocean structure since 2006»
Second, ignore the inconsistencies, and just assume those pesky CO2 molecules are so clever that they can change the trajectory of planetary temperature trends every few decades, from warming to cooling, back to warming, then just «flatline» for fifteen years or so.
The agreement leaves us on track for 3 degrees of warming and planetary emergency.
Easterbrook's predictions were «right on the money» seven years before Al Gore and the United Nation's Intergovernmental Panel on Climate Change (IPCC) shared the 2007 Nobel Peace Prize for warning that the Earth was facing catastrophic warming caused by rising levels of carbon dioxide, which Gore called a «planetary emergency.»
Then, for the benefit of the lay reader, who would not be expected to understand the clear (to a competent physical scientist) implication of this simply - stated fact, I wrote: «This in fact indicates that the Venusian atmosphere is heated mainly by incident infrared [not the VISIBLE portion, which is indeed largely reflected, defenders, but INFRARED] radiation from the Sun, WHICH IS NOT REFLECTED BUT ABSORBED [or allowed in to heat the lower atmosphere] by Venus's clouds, rather than by warming first of the planetary surface.
They worked out how these proportions would change if the average planetary temperatures reach 2 °C above the «normal» of the pre-industrial world, and they found that human - induced global warming could already be responsible for 18 % of extremes of rain or snow, and 75 % of heatwaves worldwide.
«In fact, 50 % of voters now believe that global warming is caused primarily by long - term planetary trends, a high for the year.
Climate - change skeptics point out that the planet has warmed and cooled many times before, but the climate window that has allowed for human life is very narrow, even by the standards of planetary history.
Moreover, the loss of sea ice would have altered the planetary albedo, causing the planet to warm until clouds cover had increased enough for the radiation balance at the TOA to be restored.
For instance, given the physics of sulphate aerosols in the stratosphere (short wave reflectors, long wave absorbers), it would be surprising if putting in the aerosols seen during the Pinatubo eruption did not reduce the planetary temperature while warming the stratosphere in the model.
Projections for the way in which our planet will be affected by the current trend of rapid planetary warming are dire.
Instead of publicly expressing their views, a group of parliamentarians said skeptics should parrot the imploding official narrative: The notion that global warming, which even leading alarmists admit has been on «pause» for 17 years in defiance of every UN climate model, is caused by human activities and requires planetary carbon taxes and more government control.
The conclusion: Planting a forest in the United States could cool the Earth for a few decades, but would lead to planetary warming in the long term.
