Global climate change

Pacific decadal oscillation to The ocean and atmosphere can work together to spontaneously generate internal climate variability that can persist for years to decades at a time. Due to the long timescales of this circulation, ocean temperature at depth is still adjusting to effects of the Little Ice Age [17] which occurred between the and s.

An increasing number believe that any warming is so small it is indistinguishable from the noise in the environmenal data sets, and that the data have not been properly adjusted for such things as urban heat island effects are the city temps warmer than the suburbs where you live?

Has the city grown since ? Have the runways increased near the temp gage at your airport since ? Most scientists agree that warming is better than cooling and many believe CO2 provides important enhancements for forests and agriculture, even while also believing we should not be fouling our nest. Our site makes every effort to present the true science of climate change.

Global Warming and Climate Change skepticism examined

When the news broke of the Arctic ice being at its 30 year low inthe same source U. To show the imbalance, as one reads in the popular press, we have created a companion site that presents the evidence for global coolingjust as most newspapers and alarmists present only the science that supports warming.

There are many reasons to be cautious about accepting CO2 as the causative agent if there really is warming.

This is highlighted by 2 papers published in March They claim both factors are underappreciated by IPCC. Many scientists believe the temperature changes are more dependent on the sun than CO2, similar to the relationship in your home with your furnace.

The soot may well explain much of the Arctic melting, as it has recently for Asian glaciers. It is generally accepted that the Earth has been much warmer than today, for example, in the time of the dinosaurs the mid-cretaceous period when the CO2 was 2 to 4 times greater than today NOAA.

More recently, in the prior period between ice ages, justyears ago, the Earth also was much warmer than today and the sea level much higher - by about 13 to 20 feet 4 to 6 meters IPCC. The primary driver of the past climate shifts is believed to be orbital mechanics and solar variability, with some contribution from Earth geophysical processes, such as volcanic eruptions.

In a first attempt Hadley-chart to use a CO2 - based model to predict temperatures, the results are not impressive at all and are exactly opposite observations. The cause of the temperature rise, and therefore the future course, is settled only within the consensus group of scientists.

There are many other scientists who are non-modelers, many with backgrounds as atmospheric physicists, climatologists, engineers, meteorologists, and paleo-climatologists, who do not believe the primary cause is mankind, although this could be part of it. These scientists and the people who follow them are often called climate change skeptics.

Most of these scientists believe that the sun is at the root of the warming if anybut that other factors are also at work.

Among scientists and concerned citizens are thse who believe that the link between CO2 and warming is the last great hope to decrease the pollution inherent in the burning of fossile fuels. This leads them to rebel at any science, or any statements, that diminishes their ability to foster a reduction in fossil fuel usage.

To help separate fact from fiction, an explanation of these thoughts is included here, along with links to these materials. The Hadley prediction chart and the observation chart below are from the Climatic Research Unit CRU at the University of East Anglia, w hich is well respected for its historical databases maintained at the global level, and which are used in IPCC assessments.

See the Hadley composite charts for to present by month, year and quarter by hemisphere. Note that "global" warming is greatest in the Northern hemisphere. Links to similar charts, but all slightly different with different assumptions or algorithms to fill in missing or sparse data, are provided in the left margin.

Agency JMA site is recommended because it is interactive and allows you to query the data base. This will confirm the IPCC models that predict more warming will occur during the winter months than the summer. This chart looks ominous until put into the context that the average temperature for is Scientifically, we should use absolute temperatures, which would add an additional C F degrees.Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time (i.e., decades to millions of years).

Climate change may refer to a change in average weather conditions, or in the time variation of weather within .
