The probability of warming may be greater, but cooling’s mass starvation begs us to plan for both – J. Everett
Are you skeptical or gullible? Consider your official gage, probably your airport’s thermometer. Are there more nearby runways, jet and auxiliary engines, roads and heated or cooled buildings, asphalt roofs, and automobiles since its installation? Do their windows make them all greenhouses? Has the road been widened, getting closer to the gage? Is there more soot on the snow and ice? Are there more people at 100 watts each? Are there people and their animals, whether as pets or food – averaging another 100 watts total for each person? How can CO2 rise so rapidly while temperatures do not? How many times does CO2 need to double before it does not round to Zero? When your air conditioner comes on, where does it put the heat? Where does your attic fan put its heat? Is this warm period (Holocene) about to end with a return to glaciation? Does the soot on the Arctic ice make it melt faster than in Antarctica? On this site we present answers and more questions about climate change facts.
Facts about Global Warming
Virtually all scientists agree that the Earth has warmed a small amount since the year 1000 or, if you choose, since 1850, …
Reality Check
In the prior inter-glacial period about 125,000 years ago, there was no summer ice at the North Pole and the sea level was 15 feet (5m) higher than today. …
The IPCC Forecast
CO2 (the most important gas) has risen from 280 parts per million (ppm) to slightly over 400 since pre-industrial times and …
Impact Assessment Needs
My specialty is in impacts assessment (oceans, coasts, fisheries, polar regions), but now I have published also on the science of climate change. …
How to Identify Bias
When reviewing impact assessments, look for bias. Often the authors think only of negative changes. This is not necessarily because of personal agendas ….
IPCC Forecast Vs. Reality
CO2 has usually been associated with temperature rise throughout the history of the Earth. It is indeed a greenhouse gas but it operates on…
Forecast is Not Huge
Oceans and coastal zones, the things I know best, have been far warmer and colder than is projected in the present scenarios of climate change. Marine life has been in the oceans nearly since when they were formed. …
Was the Earth Warmer before?
IPCC: Global average sea level in the last interglacial (Eemian) period (130,000-111,000 years ago) was likely 13 to 20 feet (4 to 6 meters) higher than during the 20th century, mainly due to the retreat of polar ice. …
What Shall We Do?
We should respond prudently to the threats from climate change. These actions should include things that make sense in their own right and which will be important whether the Earth warms or cools in the near future. …
What Should We Not Do?
We must respond prudently to the threats from climate change. We live in a global economy, much of it with lower production costs than our own in the developed world. …
Issues of Disagreement
There are four elements separating consensus and skeptic scientists. Not all elements are disputed by everyone. …
Skeptics View of Consensus
Very Few Scientists. Few scientists are actually involved in writing the materials, perhaps a few dozen. …
Consensus View of Skeptics?
On Somebody’s Payroll. Many press articles have been written to say that scientists who disagree do so because they are being supported by oil companies or some other group with a stake in the outcome. …
Is Ocean Acidification Real?
There is not a problem with increased CO2 in the water, leading to acidification. …
Is Global Warming Bad?
The IPCC Reports Suggest There Will be More Losers than Winners with Warming. The IPCC process includes many unlikely scenarios. These worst-case estimates also have associated impacts, from benign to worst-case. . …
Polar Bears/Polar Ice?
Polar Bears have Endured Warmer Periods than are Forecast by IPCC. …
CO2 so high we can’t breathe?
There is no threat to our ability to breathe. Oxygen and nitrogen still make up 99% of our atmosphere. With Argon, we are at 99.9 %. The trace gases including Methane, CO2 and the other greenhouse gasses make up a minuscule part of what we breathe, but they have important abilities to make the Earth warmer. …
