A Quote by Martin Rees

One of the computer models for a four degree temperature rise would give rise to a 10 degree temperature rise in Africa. And bear in mind also that in the depth of an ice age the mean temperature drop compared to the present was five degrees.
The important point there is that when people talk about a mean temperature rise of say two, three or four degrees that's a sort of global average which really is a signature of large scale change in climatic patterns.
Diversity is a survival factor for the community itself. A community of a hundred million species can survive anything short of total global catastrophe. Within that hundred million will be thousands that could survive a global temperature drop of twenty degrees—which would be a lot more devastating than it sounds. Within that hundred million will be thousands that could survive a global temperature rise of twenty degrees. But a community of a hundred species or a thousand species has almost no survival value at all.
We are watching things happen with one degree changes in ocean temperature that we thought wouldn't happen until there were two or three degree changes in ocean temperature. These are facts.
If you have a temperature rise, if it's a problem in one area, it's beneficial in another area. But sea level is the real 'bad guy,' and therefore they [The IPCC] have talked very much about it. But the real thing is, that [sea level rise] doesn't exist in observational data, only in computer modeling.
The reality is that no country's actions alone will create the impact required to limit global temperature rise to 2 degrees Celsius - we all need to be part of the solution.
We have no choice: we must protect Arctic ice, enable it to continue to act as an essential temperature regulator for the planet, avoid the catastrophic rise in sea levels that would result from the ice melt, and stop the disappearance of permafrost releasing irreversible quantities of greenhouse gases back into the atmosphere.
Out of the huts of history's shame I rise Up from a past that's rooted in pain I rise I'm a black ocean, leaping and wide, Welling and swelling I bear in the tide. Leaving behind nights of terror and fear I rise Into a daybreak that's wondrously clear I rise Bringing the gifts that my ancestors gave, I am the dream and the hope of the slave. I rise I rise I rise.
I remember feeling the temperature change the first time the curtain came up, the difference between the audience temperature and the stage temperature. I'll never forget it.
We are on track for a 3.5 deg C rise by 2040 (i.e. 4.2 deg C relative to pre-industrial)... When I look at this data, the trend is perfectly in line with a temperature increase of 6 degrees Celsius, which would have devastating consequences for the planet. We have 5 years to change the energy system, or have it changed
Few scientists now dispute that today's soaring levels of carbon dioxide and other gases in the atmosphere will cause global temperature averages to rise by as much as nine degrees Fahrenheit sometime after the year 2000.
every man is free to rise as far as he's able or willing, but the degree to which he thinks determines the degree to which he'll rise.
Imagine what our planet would look like with an increase in temperature of two degrees or four degrees, given that at 0.8 degrees we already have serious problems in the world.
Global warming is one of those things, not like an earthquake where there's a big bang and you say, 'Oh, my God, this is really, has hit us.' It creeps up on you. ... Half a degree temperature difference from one year to the next, a little bit of rise of the ocean, a little bit of melting of the glaciers, and then all of a sudden it is too late to do something about it.
In the APS (American Physical Society) it is ok to discuss whether the mass of the proton changes over time and how a multi-universe behaves, but the evidence of global warming is incontrovertible? The claim (how can you measure the average temperature of the whole earth for a whole year?) is that the temperature has changed from ~288.0 to ~288.8 degree Kelvin in about 150 years, which (if true) means to me is that the temperature has been amazingly stable, and both human health and happiness have definitely improved in this 'warming' period.'
You can swim (uncomfortably) in water at a temperature slightly above freezing; a tiny drop in temperature-or a miracle-allows you to walk on water.
...the possibility of circular reasoning arises-that is, using the temperature record to derive a key input to climate models that are then tested against the temperature record.
