The global atmospheric and sea surface temperatures are rising at an alarming rate and can be strongly linked to human activities such as fossil fuel combustion. On burning of fossil fuels, a vast amount of carbon dioxide gas is emitted into the atmosphere.Although CO2 is required to trap heat from the sun, an increase in the gas will lead to rapid warming of the Earthâs surfaces via the Greenhouse Effect that will seriously affect other global processes essential for life.n burning of fossil fuels, a vast amount of carbon dioxide gas is emitted into the atmosphere.

Definition of 'oxyhemoglobin'. Word Frequency. oxyhemoglobin in American English (ËÉksÉªËhimoÊËgloÊbÉªn ; Ã¤kËsihÄËmÅglÅËbin) noun. the bright-red substance that is found in the arterial blood, formed in the lungs by the loose union of hemoglobin with oxygen: it delivers its oxygen to the body tissues.
Oxygen saturation is defined as the ratio of oxy-hemoglobin to the total concentration of hemoglobin present in the blood (ie Oxy-hemoglobin + reduced hemoglobin).emoglobin is responsible for transporting oxygen from lungs to other parts of the body, where the oxygen can be used by other cells. Oxy-hemoglobin (HbO2) is the bright red hemoglobin that is a combination of hemoglobin and oxygen from the lungs. A hemoglobin molecule can carry a maximum of four oxygen molecules.
