The purpose of this study is to show the Sun controls the Earth’s temperature daily and over decades and millennia. A secondary objective is to show CO2 contributes to the warming of the Earth through increased enthalpy (heat content). The methodology is to record temperature and relative humidity at many weather stations around the globe to provide a picture of the constantly changing atmosphere over twelve months. Daily measurements of the molecular fraction of CO2 are converted to weight to calculate the increasing enthalpy of the atmosphere. The Sun controls Earth’s temperature through water vapor up to the dewpoint temperature line and by direct heat radiation from the Sun above it. The enthalpy contribution by CO2 from 1750 to 2022 was up to 0.0000049 kJ/kg of dry air, equivalent to a temperature increase of 0.000181oC over 272 years. The effect of CO2 on warming the Earth has a negligible increase in Earth’s temperature.

The current controversy over the cause of increasing global temperatures since the middle of the 20th century comes from the IPCC First Assessment Report issued in 1990. The report states rising carbon dioxide (CO2) warms the air, thereby holding more of the significant warming gas, water vapor. This additional water vapor feeds back to amplify the warming by CO2. The IPCC has continually promoted this concept in its reports since 1990. Up-to-date science proves the IPCC concept is faulty. Scientists discovered that when the Sun's energy output changes, it impacts the Earth's temperature, and it does this cyclically. Current, reliable evidence shows the Earth has just come through a warm period. It is now in the early stages of cooling that might be similar to the Dalton Minimum and last for three or four decades. Average temperatures can drop by up to 1.5oC and increase the rate of crop failures that have already started. It won't be easy to maintain the benefits of the recent warm phase of the Sun during the upcoming solar minimum.

During the last decade, the role of the government and the professional corporations in approving graduate programmes, licensing interns and residents and requesting statistical information has expanded greatly. The result has been a dramatic increase in administrative workload. At McGill University, the response of the Faculty of Medicine was the introduction of a Computerized Administrative Monitoring System (CAMS) for interns and residents, which provides immediate access, via a video display terminal, to any applicant's or trainee's information file. CAMS also provides timely reports on the status of administrative requirement for both the specialty programmes and the interns and residents assigned to them. The design and implementation of CAMS on the central university time-sharing computer system is described. Some measures of the effort of design, implement and run the system are included, along with an indication of the benefits to the clerical and medical staff who administer the 40 specialty programmes and some 1000 medical trainees.

This study provides temperature estimates about the effect of carbon dioxide (CO2) in warming the Earth’s atmosphere using readily available information. It compares the grams of water vapor per kilogram (kg) of dry air with the number of grams of CO2 per kg of dry air. This comparison is over a year for 20 representative areas of the Earth. It shows the grams of water vapor range from 0.1 to 44.0 times that of CO2. The increased heat content (enthalpy) of the atmosphere by CO2 causes a maximum temperature increase of 0.006oC from the Poles to the Equator. This amount is too small to measure. These quantitative results indicate that the Tropics, representing 39.8% of the Earth’s surface, contain almost three-quarters of the atmosphere’s water vapor. In contrast, the Arctic and Antarctic areas at the Poles have an estimated 0.9% of the atmosphere’s water vapor. Water vapor is the significant greenhouse gas that keeps the Earth from being a frozen planet.

This paper describes a system using a new integrated package called SYMl3L. The total system combines the SYMBL software, an interactive display package, a government supplied data base of topographical information, and an associated workstation, which provides high resolution color graphics. One of the outputs features an automated topographic data base verification with two and three dimensional views. This latter option proved t o be a very important one when establishing radio coverage. Other options allow the display of data in various ways on the CRT screen, color plotter or laser printer.The total system calculates the radio wave propagation receiver points at a rate exceeding 100 points/second, with any desired density and over any desired area coverage.
