The 97 Climate Scientists from http://skepticalscience.com/nsh/

#1 Professor Michael Mann ... Pennsylvania State University ... Expertise: Past climate change, atmospheric dynamics, oceanography
There are now dozens of hockey sticks and they all come to the same basic conclusion. The recent warming does appear to be unprecedented as far back as we can go. But even if we didn’t have that evidence, we would still know that humans are warming the planet, changing the climate and that represents a threat if we don’t do something about it.

#2 Professor Katharine Hayhoe ... Texas Tech University ... Expertise: Climate impacts
Year by year, decade by decade, gradually over long periods of time, we see that the earth’s temperature is rising and we know from very careful scientific studies that have been done, that the majority of this warming is due to human production of heat-trapping gases.

#3 Professor Marshall Shepherd ... University of Georgia ... Expertise: Atmospheric sciences, water cycle
Weather is your mood and climate is your personality. So on any given day, you can have really cold weather or really violent weather. But the scientific literature does suggest that our climate
is changing. Almost every weather phenomenon happens in a warmer and more moist climate.

#4 Dr. Peter Gleick ... Pacific Institute ... Expertise: Water & climate
We know that humans are raising the temperature through the emission of greenhouse gases. We’re beginning to change the climate. Among the things that we’re going to see is more of the hydrologic cycle is going to be rain, and less of it’s going to be snow. As it gets warmer, the snow line is going to move up. What does fall as snow is going to melt earlier, and runoff faster.

#5 Dr. Gavin Schmidt ... NASA Goddard Institute for Space Studies ... Expertise: Climate modelling, climate variability
...what we anticipate is that because we’re continuing to add carbon dioxide to the system, we’re going to continue to warm decade by decade by decade. The exact magnitude of where we’re going to go is going to depend a little bit on the system, but also on the decisions that we make as a society to either reduce carbon emissions or just to carry on with business as usual.

#6 Professor Maureen Raymo ... Columbia University ... Expertise: Past climate change, past sea level rise
Everything I’ve learned about our planet’s past climate history places me, like most of my colleagues, in the camp that says we need to take preventive action to keep the planet from warming further.

#7 Professor Jason Box ... Geological Survey of Denmark and Greenland ... Expertise: Glaciology, Greenland ice sheet
There’s no debate. It’s really quite simple. We’ve overloaded the atmosphere with heat trapping gas and the rest are just details.

#8 Professor Simon Donner ... University of British Columbia ... Expertise: Climate variability, coral reef impacts
The take-home message of my coral reef research is that without serious, near-term efforts to reduce greenhouse gas emissions and to increase coral reef resilience, the world’s coral reefs will experience dangerously frequent mass bleaching events within decades.

Climate change is coming. If you want to know what it looks like, just look at the Midwest right now. It’s drought; it’s heat. Warmer temperatures don’t mean barbecues and tank tops. It means drought; it means fire; it means suffering.

#10 Professor Piers Forster ... University of Leeds ... Expertise: Climate modelling, climate impacts
Compare climate change to a train trundling across America. Some way down the track, we are not sure how far, the bridge is out and disaster looms. Do we want to be the ones to sit back and watch the train wreck, or do we want to be the hero?

#11 Dr. Ken Caldeira ... Carnegie Institution for Science ... Expertise: Ocean acidification, climate impacts, carbon cycle
If you’re talking about mugging little old ladies, you don’t say, ‘What’s our target for the rate of mugging little old ladies?’ You say, ‘Mugging little old ladies is bad, and we’re going to try to eliminate it.’ You recognize you might not be a hundred per cent successful, but your goal is to eliminate the mugging of little old ladies. And I think we need to eventually come around to looking at carbon dioxide emissions the same way.

#12 Professor Richard Alley ... Pennsylvania State University ... Expertise: Glaciology, Sea Level Change
So we know the globe is warm. If you look today, the average temperature of the whole world is above its long-term average. If you look in the north, in the Arctic, it’s a good bit above. The Northern Hemisphere is, the Southern Hemisphere is, the tropics are, the Antarctic are. The big enough pieces are above average. And that’s because we’ve raised CO2 in the atmosphere.

#13 Professor David Karoly ... University of Melbourne ... Expertise: Climate variability, weather extremes
It’s clear that human-caused changes in climate, particularly due to the increases in greenhouse gases in the atmosphere, will get worse for a substantial period of time. And we know that increasing greenhouse gases in the atmosphere are already causing large-scale changes in temperature, increasing temperatures around the globe.

When we see records being broken and unprecedented events, the onus is on those who deny any connection to climate change to prove their case. Global warming has fundamentally altered the background conditions that give rise to all weather. In the strictest sense, all weather is now connected to climate change.

We've lost about 75% of the Arctic's sea ice in just 30 years. It doesn't take a scientist to see this huge change in the climate system, and we know it's mainly due to the extra heat trapped by increasing greenhouse gases from burning fossil fuels. Watching the Arctic warm so fast gives me

This study is the strongest evidence yet that the world’s natural ecosystems will undergo profound changes—including severe alterations in their species composition—through the combined influence of climate change and land use. Conservation of the world’s biota, as we know it, will depend upon rapid, steep declines in greenhouse gas emissions.

Unabated climate warming of several degrees over the next century is likely to speed up the collapse of West Antarctica, but it could also trigger irreversible retreat of marine-based sectors of East Antarctica. Whether we should do something about it is simply a matter of common sense. And the time to act is now; Antarctica is not waiting for us.

#21 Professor Jeremy Shakun ... Boston College ... Expertise: Paleoclimate
We are heading for somewhere that is far off from anything we have seen in the past 10,000 years – it’s through the roof. In my mind, we are heading for a different planet to the one that we have been used to.

#23 Professor Timothy Naish ... Antarctic Research Centre ... Expertise: Ice sheets, Antarctica
If you maintain carbon dioxide levels of 400ppm and commit the planet to an atmosphere of that composition for the next 100 years, then you stand a chance of losing both the Greenland Ice Sheet and the West Antarctic Ice Sheet, having sea level potentially 10m higher than it is today.

#24 Professor Raymond Pierrehumbert ... University of Chicago ... Expertise: Climate models, past climate change
Some people seem to think that the whole global-warming concern dates back just to the 1990s, that it was put together by a bunch of environmentalists. But in fact, the physics go back almost two centuries ... By emitting so much carbon, we’ve really created a new geological era. The Holocene is over, and how different the Anthropocene is going to be depends on how much coal and oil we burn.

#25 Dr. Ailie Gallant ... Monash University ... Expertise: Climate extremes, climate variability, palaeoclimate
Building any scientific theory is like putting together pieces of a jigsaw puzzle. Pieces of evidence are assembled in order to resolve the complete picture. And the picture has never been clearer for the puzzle of human-induced climate change.

#26 Professor Stefan Rahmstorf ... Potsdam University ... Expertise: Paleoclimate, sea level rise, extreme events
Adding greenhouse gases to our atmosphere traps heat and thus raises temperatures - that is basic physics known since the 19th Century, and it is exactly what we've been observing for decades. That's why there is a 97-98% consensus amongst climate researchers that human-caused emissions are causing global warming.

#27 Professor John Bruno ... University of North Carolina ...Expertise: Marine biodiversity, coral reef ecology
One of the many factors causing the global loss of reef building corals is anthropogenic climate change, which is slowly warming the world's oceans. When summertime temperatures are warmer than usual, corals can die from 'bleaching' and disease outbreaks. This in turn is devastating for the countless organisms that inhabit coral reefs.
source=huffingtonpost.com

#28 Professor Matthew Collins ... University of Exeter ... Expertise: Climate modelling, climate variability
Further emissions of greenhouse gases will cause further global warming. The Arctic will warm most rapidly and the land will warm more than the ocean. There will be more hotter and fewer cold days. Avoiding 2 degrees of warming since preindustrial times will be very tough. We have already ‘spent’ more than two thirds of the CO2 emissions that we can afford to spend.

#29 Dr. Heidi Cullen ... Chief Climatologist for Climate Central & Visiting Lecturer at Princeton University ... Expertise: Climatology, ocean-atmosphere dynamics
We are seeing CO2 going up—it is a measurable trend, not a cyclical phenomenon. On her own, Mother Nature’s earth cannot reproduce the observed global temperature record we have measured over the past century. Solar activity, volcanoes, and variability of other types are important, but on their own they simply cannot produce the significant warming trend we are now experiencing.

#30 Dr. Warren Washington ... National Center for Atmospheric Research ... Expertise: computer modeling of Earth's climate
To get the kinds of climatic conditions we have today, you need that increase in carbon dioxide. For anyone doubtful about the effect of human activity on global warming, that finding really is a 'smoking gun'.

#31 Professor Kerry Emanuel ... Massachusetts Institute of Technology ... Expertise: climate models
Back in the 1980s, I did not feel there was enough evidence to warrant much concern about climate change. But great advances in paleoclimate, analysis of in-situ and satellite observations, my own acquisition of some basic understanding of climate physics and, yes, climate models have all added up to very compelling evidence that we are changing climate and engendering serious risks in doing so.

#32 Professor Veerabhadran Ramanathan ... University of California, San Diego ... Expertise: climate change mitigation
The additional heat trapped by the increase in greenhouse gases from the late nineteenth century to the present time has committed the planet to a global warming in the range of 1°C to 3°C. We have realized only a fraction (25–50 percent) of this warming. ... Every decade we delay in taking action, we are committing the planet to additional warming that future generations have to deal with.

#33 Professor Ann Henderson Sellers ... Macquarie University ... Expertise: Climate change models & communication
With the latest IPCC Assessment Report from 2007 the question is no longer about whether human activities are changing the climate, but about how fast and with what impacts? Frankly, I find it discouraging that climate sceptics and greenhouse nay-sayers still get so much attention in our mass media - and apparently credibility with the general public.

#34 Professor Matthew England ... University of New South Wales ... Expertise: Oceanography, ocean modelling & climate processes
First, greenhouse gases trap heat. This has been known for almost 200 years. Second, fossil fuel burning is driving dramatically higher concentrations of these greenhouse gases in the atmosphere, and so as a direct result, extra heat is being held in the Earth's climate system. This is warming the oceans, the atmosphere, and melting ice at unprecedented levels. And third, doing nothing to limit fossil fuel burning will lead to costly and dangerous levels of climate change.

#35 Dr. Gerald Meehl ... National Center for Atmospheric Research ... Expertise: El Niño, anthropogenic forcings
Even if you stabilize the concentration of greenhouse gases, you are still committed to a certain amount of climate change no matter what you do because of the lag in the ocean. The longer you wait to do something, the more climate change you are committed to in the future.

The perennial ice cover, or ice that survives the summer melt, has been observed as part of the Arctic sea ice cover for 1,450 years. The extent of the perennial ice has been declining at a rapid rate of about 11% per decade. The observed rate of decline is expect to continue because of anthropogenic global warming which is expected to be amplified in the Arctic region because of ice-albedo feedback.

#40 Professor Noah Diffenbaugh ... Woods Institute for the Environment ... Expertise: Climate dynamics, climate impacts
We know from past changes that ecosystems have responded to a few degrees of global temperature change over thousands of years. But the unprecedented trajectory that we're on now is forcing that change to occur over decades. That's orders of magnitude faster, and we're already seeing that some species are challenged by that rate of change.

We do know why CO2 causes warming. It's basic physics that's been known for more than a century. It's pretty straightforward. If you put more CO2 and other greenhouse gases into the atmosphere, it will get warmer - there is no way around that one.

#44 Professor Inez Fung ... University of California, Berkeley ... Expertise: Biogeochemical cycles, carbon cycle
As CO2 rises, because we understand the physics of the CO2 warming, more warming is expected. There are natural processes which amplify the warming from CO2 - the warmer air can hold more moisture - water vapour is a greenhouse gas and so that amplifies the initial warming. The melting of ice exposes a darker surface and so more sunlight is absorbed. So we are very sure that the CO2 rise will lead to more warming.

#45 Dr. Richard Feeley ... Texas A&M University ... Expertise: Carbon cycling, ocean acidification
Carbon dioxide is an acid gas. It reacts with water to form carbonic acid. And then that carbonic acid completely disassociates. It forms a hydrogen ion and bicarbonate, and in doing so, it reduces the pH of seawater. Since the beginning of the Industrial Revolution, that pH change has been about 0.1 pH units, which is a 30 % rise in acidity of the surface ocean.

CO2 in the atmosphere, currently, is higher than it has been in at least two million years. What is also significant is that the rate of increase is rapid.

Carbon dioxide that is released into the atmosphere by burning fossil fuels changes ocean temperature, alters ocean circulation and makes the ocean more acidic.

There is overwhelming evidence that human-induced climate change is already real and will increase.

There are a few aspects that don’t allow us to say with 100% certainty, but what we can say is that we are 95% certain that human activity is the main cause of global warming. Our best estimates actually account for all of the observed change since the 1950’s and that the alternatives, solar variability and natural variations have nothing to contribute over this period.

Climate change, resulting from human activities, is occurring all around us. It can be seen in the temperature record, in sea level rise and in the seasonal greening of landscapes. The impacts are measurable in changing frequency of extremes, in impacts on heat waves, and in the nutritional value of some crops. Not accepting the science prevents the planning that minimizes risk and would help build resilience. We are currently choosing to be more vulnerable than we need to be in the future and that is stupid.

Our habit to produce energy by burning fossil fuels causes global warming. Civil societies and policy makers will have to make a choice about how much climate change will be too much. Currently, the international community regards 2ºC as such a level, which is not safe, but which might prevent many of the more dramatic impacts.

The human influence on climate change is clear and dominant. The atmosphere and oceans are warming, the snow cover is shrinking, the Arctic sea ice is melting, sea level is rising, the oceans are acidifying, and some extreme events have increased. CO2 emissions from burning fossil fuels need to substantially decrease to limit climate change.

We live on a water planet. What that means in practical terms is that it takes decades or more for the earth to heat up, or cool off, as greenhouse gases increase or decrease. So the greenhouse gases that we add, our kids will have to deal with, and they do their kids will have to deal with, and so on. This will continue until one generation breaks the cycle by placing more value on long term benefits for their kids instead of short term profits for themselves.

We expect climate to be warmer in the future than in the past because we know that greenhouse gases absorb and then re-emit thermal radiation.

Current reserves of fossil fuels are five times more than we can afford to burn if we want to keep global warming to less than 2°C; and we have to keep global warming below 2°C.

#88 Professor Anders Levermann ... Potsdam University ... Expertise: Sustainable solutions, adaptaion strategies
There are not many human activities whose impact can reasonably be predicted decades, centuries, or even millennia in advance. The fallout from nuclear waste is one; humans’ contribution to global warming through greenhouse-gas emissions from burning fossil fuels, and its impact on rising sea levels, is another.

#89 Professor Wally Broecker ... University of Columbia ... Expertise: Ocean’s role in climate change
One of the main drivers of ice ages was the CO2 content in the air. When the CO2 was lower it got plenty colder. So, as we add CO2 it’s going to get a lot warmer. There can be a question about how big the warming will be, but there’s no doubt in my mind that warming has occurred.

#90 Professor Gifford Miller ... University of Colorado, Boulder ... Expertise: Quaternary stratigraphy, paleoclimatology
The key piece here is just how unprecedented the warming of Arctic Canada is. This study really says the warming we are seeing is outside any kind of known natural variability, and it has to be due to increased greenhouse gases in the atmosphere.

#91 Professor Michael Oppenheimer ... Princeton University ... Expertise: Climate change & its impacts
We know that greenhouse gases trap heat that would otherwise escape into space and that their build-up will inevitably warm Earth. We know that Earth is warmer than it was a century ago and we know that it is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century.

#92 Professor Richard Pancost ... University of Bristol ... Expertise: Paleoclimate, geomicrobiology
What we understand well is that humans have increased atmospheric CO2 and that has caused and will continue to cause global warming. There are uncertainties in exactly how temperature and sea level will rise. And there is uncertainty regarding its impacts, especially on food and water security. But such uncertainty is a cause for action, not inaction.

#93 Professor Peter Cox ... University of Exeter, UK ... Expertise: Carbon cycle feedbacks, pollutants
Scientists are like cats, we are not herdable, ask any University! We don't like to agree, in fact we are motivated by not agreeing, so how could we possibly get to the point where we can agree? Is it the Intergovernmental Panel of Cat Control? No it's not! Part of the reason we agree is because some of it's obvious. It's been obvious for a long time.

#95 Dr Katrin Meissner ... University of New South Wales ... Expertise: Abrupt climate events, climate feedbacks
Let's imagine we decide to stop all fossil fuel emissions today, worldwide, forever... the climate will not immediately jump back to where it was before human intervention. The longer we wait, the more warming we will be committed to. We are now setting the course for our immediate future and for generations to come. We are more vulnerable than most of us realise.

#96 Dr Alan Robock ... Rutgers University ... Expertise: Volcanic eruptions, climate impacts
If you ask climate scientists, the ones that publish in the journals, the ones that do the research, the ones that understand the science, more than 97 percent of them agree that humans are the main cause of global warming. And so, by saying that other people who claim to be scientists don't agree, or by having debates between one global warming denier and one climate scientist, it makes it seem like there's a much stronger argument on the side of the deniers.

#97 Dr. Greg Holland ... National Center for Atmospheric Research ... Expertise: Tropical meteorology, severe weather
...the overwhelming consensus is that the globe is warming. The overwhelming consensus is that this is making changes to severe weather and rare events, be it heavy rainfall, droughts, tropical cyclones or whatever.

Why does Malemute have to put all that copy paste in here?

You already have about 20,000 posts saying humans are the cause of climate change.

This planet is put here because of us.

It didn't just appear out of nowhere.

It was put here for a purpose.

We create the WORLD.

You don't even have to have any graphs or data to "see" the changes caused by
mankind's ruthless selfish attacks against their own self interests due to poor fund of knowledge.

Everything we do has an effect on this world including the climate.

We are not independent in our current lives on this planet from material nature.

When we are disharmonious from material nature then the climate automatically changes.

We are NOT the ultimate controllers.

We only have minute control.

Material Nature operates under stringent laws to keep those in poor fund of knowledge in check ......

Werner...not everyone agrees on the cause and effects of humans on this planet. It is nice to see the over whelming majority of experts do agree on the major causes of global warming.


Amazing how some on this thread strut their ignorance with such confidence.

That is pretty much in line with what Pope Gregory ix stated regarding the RCC's doctrine under his breath. Then he outright mandated regarding anyone such as the individual below that played any part in this dudes club of denialism, was to be totally discredited, ex-communicated and eventually put to death for being a heretic/non-believer/non-conformist amongst the over whelming consensus of the time.

Amazing how "Man's" dogmatic history truly repeats itself....

Peter of Bruys (also known as Pierre De Bruys or Peter de Bruis; fl. 1117 – c.1131) was a popular French religious teacher, who is called a heresiarch (leader of a heretical movement) by the Roman Catholic Church because he criticized infant baptism, opposed the erecting of churches and the veneration of crosses, opposed the doctrine of transubstantiation, and denied the efficacy of prayers for the dead An angry mob killed him in or around the year 1131.

This too shall pass, as it has so many times in the past. We will get over it. Just like we did back in the 30's when there was no such thing as AGW. Just good old climate and droughts and tornado's and hurricanes and....

LOL the human was the ONLY dust bowl component.

Morons tried to farm the desert without irrigation! Dumbass beat farmers (on stolen land no less)

Such a natural disaster, lol.

Yeah boy howdy momma nature!

The dust bowl was a direct result of human activity. As was the despoiling of Mesopotamia.

If a tree falls in the forest and there are no humans around, who gives a sh#t?

Or reworded, 'drought' is a human condition. If you make a farm in the desert dependent on rainfall, don't be blaming nature when the rain doesn't fall. You'd be a complete dumbass if you did that.

Read up on what those west Texas dumbasses have done to their aquifer. WE Californians are replicating that experiment in the Central Valley.
