Here I analyze the observed and projected surface temperature anomalies over land between 50°S-50°N for the period 1950-2099 by large-scale ecoregion and find strongest warming consistently and persistently seen over driest ecoregions such as the Sahara desert and the Arabian Peninsula during various 30-year periods, pointing to desert amplification in a warming climate. This amplification enha...

A version of the Canadian Middle Atmosphere Model that is coupled to an ocean is used to investigate the separate effects of climate change and ozone depletion on the dynamics of the Southern Hemisphere (SH) stratosphere. This is achieved by performing three sets of simulations extending from 1960 to 2099: 1) greenhouse gases (GHGs) fixed at 1960 levels and ozone depleting substances (ODSs) var...

Increasing concentrations of greenhouse gases (GHGs) such as CO2 in the atmosphere is a global warming. Human activities are a major cause of increased CO2 concentration in atmosphere, as in recent decade, two-third of greenhouse effect was caused by human activities. Carbon capture and storage (CCS) is a major strategy that can be used to reduce GHGs emission. There are three methods for CCS: ...

An experimental system for detecting infrared absorption using the photoacoustic (PA) effect is described. It is aimed for use at high-school level to illustrate the difference in infrared (IR) absorption among the gases contained in the atmosphere in connection with the greenhouse effect. The experimental system can be built with readily available components and is suitable for small-group exp...

This study highlights the economic and environmental challenges of recycling in Ontario, specifically examining the effect of attempting to increase the emissions target for the province’s Waste Electronics (WEEE) program. The findings from the cost model analysis found that Ontario’s Electronic Stewardship program reduces overall carbon emissions by approximately 205 thousand tonnes every year...

Global climate change is the greatest environmental challenge facing the world today. The most urgent issue is how to prevent further accumulation of greenhouse gases (GHGs) that will only fuel the process. The next priority is to implement adaptive measures, limiting harm to the extent that climate change cannot be avoided. Some degree of climate change is inevitable, imposing substantial cost...

By 2050, the earth’s population is expected to be more than 9 billion. The need for secure food and water supply will force agriculture to increase production. The major greenhouse gases (GHGs) from the livestock sector are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) throughout the production process. These gases are the key contributor to an in...

This analysis explored the effect of battery electric vehicles (BEVs) on greenhouse gas emissions (GHGs) in a panel twenty-nine countries from European Union (EU) 2010 to 2020. The method moments quantile regression (MM-QR) was used, and ordinary least squares with fixed effects (OLSfe) used verify robustness results. MM-QR support that all three quantiles, economic growth causes positive impac...

Greenhouse gases (GHGs) help to maintain the Earth’s temperature by trapping heat. Without GHGs, our planet would be so cold that no life could exist. In present era, human activities such as burning of fossil fuels emit huge amounts GHGs into atmosphere each year. Consequently, is increasing an uncomfortably high level. To halt rise in temperature, we must reduce and ultimately eliminate GHG e...
