Sentences with phrase «natural cooling phases»

Not exact matches

This NASA analysis highlights that the recent lull in surface temperatures is simply the result of natural variability superimposed upon the global warming trend - the cool phase of a cool / warm oscillation.

«The Earth goes through phases of warming and cooling, and though all the computer models we have show that we are in a warming phase, there is no way to differentiate between a natural warming and one that is human - caused.»

This cooling is the result of natural long - term swings in ocean surface temperatures, particularly swings in the Interdecadal Pacific Oscillation or mega-El Niño - Southern Oscillation, which has lately been in a mega-La Niña or cool phase.

At that time, there were major advances in Building Sector technologies — in glazing materials (heat mirror and low - e coatings), passive and active solar energy systems design and applications, passive and active cooling applications, natural ventilation systems, phase - change materials, moveable insulation, building simulation modeling programs, daylighting systems and controls, energy management systems, night set - back thermostats and occupancy sensors, solar hot water heating, solar thermal electric generation and storage, photovoltaics and advances in low - energy lighting systems, to name just a few.

There is absolutely nothing to suggest that carbon dioxide is a climate driver beyond a spurious correlation with temperature in Antarctic ice cores where blinkered climate scientists talked up the supposed CO2 - amplified warming phase but then just ignored the cooling phase that told them CO2 was obviously dominated by natural forces.

In 1975 Wallace Broeker (the guy who first used the phrase «global warming», predicted a rapid transition to warming in the 1980s, caused by a combination of rapidly rising CO2 emissions and a natural temperature cycle (derived from work on Greenland ice cores at Camp Century) which showed a rapid warming phase up to 1940, followed by the cooling phase which was attenuated by CO2.

«The global warming in 1970 - 1998 was merely a phase in the 60 - year cycles of natural warming and cooling,» Dr. Bashkirtsev says.

Scientists studying oceans demonstrate that the recent warming, to the end of the last century, is part of the natural cycle of oceanic oscillations and predict a thirty year cooling phase.

With the recent decline in solar flux and the shift to cool phases of ocean oscillations, natural climate change suggests that although glacier retreat and sea level rise will likely continue over the next few decades, the rates of sea level rise and glacier retreats will slow down.The next decade will provide the natural experiment to test the validity of competing hypotheses.

In short, Swanson and Tsonis hypothesized that when various natural oceanic cycles (PDO, AMO, etc.) synchronize (i.e. in their positive or negative phases), they can cause a short - term warming or cooling which could be described as a «climate regime shift.»

Also, the above chart of the 12 - month means clearly shows a climate that moves from cooling to warming phases, and then back - a natural oscillation that «catastrophic global warming» skeptics have long discussed, while being dismissed by the IPCC and its cohorts.

The empirical evidence continues to build within the climate science community that the world is experiencing some type of global cooling phase as a result of natural climate change forces.

As the Nature science journal indicates, currently, and for the near future, a natural PDO cooling phase may dominate.

The reality of the climate record is that a sudden natural cooling is far more to be feared, and will do infinitely more social and economic damage, than the late 20th century phase of gentle warming.

If that is the cooling phase of a natural cycle, and that cycle was in a warming phase during the late 20th century, then about half the late 20th C warming was natural, and half due to AGW.

On that basis I think we will see cooling for a couple of decades due to the negative phase of the Pacific Decadal Oscillation which has just begun then at least one more 20 to 30 year phase of natural warming before we start the true decline as the cooler thermohaline waters from the Little Ice Age come back to the surface.

With a new awareness that climate could change in serious ways, in the early 1970s some scientists predicted a continued gradual cooling, perhaps a phase of a long natural cycle or perhaps caused by human pollution of the atmosphere with smog and dust.
