Dataset Cumulative CO2 Emissions of International Transport

This dataset considers the year 1783, when the first steamship was built, as the first year of the international transport CO2 emissions. The global cumulative CO2 emissions including international transport are converted to the 1875 baseline, similar to the Global Warming baseline (1850-1900).

Global Warming and Cumulative CO2

This publication analysis a correlation between the cumulative CO2 emissions and the global surface temperature change. The change in global surface temperature was calculated as the difference in the two most recent 31 years neighboring periods, and the change in the cumulative CO2 emissions is the difference between the actual values in the centers of the periods. This approach resulted in 0.000556°C/GtCO2 for the year 2000 and 0.000745°C/GtCO2 for the year 2021.

Climate Change Rating of Countries

This work proposes a system of Climate Change Rating of countries (CCR). The parameters included in the rating are CO2 emissions per capita and per GDP, cumulative CO2 emissions in the last 30 years, and change of emissions in the last 10 years. The parameters are compared to the world averages. The rating is related to the specific CO2 emissions, lower value results in a better rating. The CCR for 2020 includes 192 countries, 99.6% of the global CO2 emissions. The A-G labels are according to groups of countries, each group with a limited number of countries, 10 countries with the best rating (A) and 10 countries with the worst rating (G). The average 2020 rating of group A is 37% and of group G - 309%. The world average CCR value is 100% equivalent to group F. Keywords: Climate Change, Global Warming, CO2 emissions, CO2 per capita, CO2 per GDP, CO2 emissions per capita, CO2 emissions per GDP, Climate Change Rating, Global Warming of countries, climate justice, carbon justice

Energy and Thermal Time Constant in Buildings

Design of building's exterior walls has important influence on energy consumption, building cost and thermal comfort. It influences also heating and cooling devices size. Optimization of energy consumption of the building requires consideration of the building materials, their thickness and mass, type and thickness of insulation, and location of the insulation layer. The correct way to optimize all the above parameters is calculation of temperatures and energy consumption in dynamic process, which means considering changes every few seconds. This may be done only with computer program. It is not easy to gain expertise on such programs. In addition, submission of input values to the program i...

Global Warming Baselines Conversion Factors

This publication includes a conversion table between various baselines of global surface temperature changes. The conversion factor from 1951-1980 to 1850-1900 baseline is +0.31°C for land+ocean, +0.49°C for land only, and +0.29°C for ocean only.

Cumulative CO2 Emissions of International Transport

The dataset of global cumulative CO2 emissions is from 1750. The baseline of this dataset is 1749. The dataset includes also international transport cumulative CO2 emissions from 1950. The baseline of international transport is 1949. This work considers the year 1783, when the first steamship was built, as the first year of the international transport CO2 emissions. In this work, the global cumulative CO2 emissions including international transport are converted to the 1875 baseline, similar to the Global Warming baseline (1850-1900). The international transport cumulative CO2 emissions caused a 0.032°C temperature increase in 2020, 2.5% of the Global Warming.

Solar Water Collector Hourly Energy Output

Calculations of solar water collector hourly thermal energy output as part of central solar water heating system with individual 150 liters storage tanks for each apartment in high rise multi-apartment residential building in Tel Aviv. The energy output at noon is 758 kcal/hr in January and 1,221 kcal/hr in April. Solar collectors supply 2,647 kWh/year of thermal energy to each apartment, minimum 5.41 kWh/day on an average day in December, maximum 8.53 kWh/day in August. Hot water supply equivalent at 40°C is 30 liter/hr in December and 81 liter/hr in August at noon, 192 liter/day in January to 500 liter/day in August.
