Humans and wild animals face new challenges for survival because of climate change. More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people's livelihoods and communities. In general, the higher the temperature, the more easily microorganisms can grow up to a certain point. Very high and low temperatures both obstruct the enzyme processes microorganisms depend on to survive. Temperatures below optimal will lead to a decrease in enzyme activity and slower metabolism, while higher temperatures can actually denature proteins such as enzymes and carrier proteins, leading to cell death. Physical Factors that Control Microbial Growth generally, an increase in temperature will increase enzyme activity. But if temperatures get too high, enzyme activity will diminish and the protein will denature. On the other hand, lowering temperature will decrease enzyme activity. High temperatures have profound effects on the structural and physiological properties of sporulating and non-sporulating bacteria, with membranes, RNA, DNA, ribosomes, protein and enzymes all affected. Microorganisms can survive in extreme climates. They are resistant to harsh climates due to their indestructible cell wall. As Pyrococcus furiosus is a microbe that is found in extreme hot climatic conditions and is isolated from shallow submarine hot springs.

Если скорость изменений соответствует скорости адаптации, то риск минимальный.

Climate change is changing water availability, making it scarcer in more regions. Global warming exacerbates water shortages in already water-stressed regions and is leading to an increased risk of agricultural droughts affecting crops, and ecological droughts increasing the vulnerability of ecosystems. The rate of growth or death of a particular microbial species is influenced by a variety of physical factors in its environment including temperature, osmotic pressure, pH, and oxygen concentration. Temperatures below optimal will lead to a decrease in enzyme activity and slower metabolism, while higher temperatures can actually denature proteins such as enzymes and carrier proteins, leading to cell death. More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people's livelihoods and communities. As climate change worsens, dangerous weather events are becoming more frequent or severe. In general, the higher the temperature, the more easily microorganisms can grow up to a certain point. Very high and low temperatures both obstruct the enzyme processes microorganisms depend on to survive. Some bacteria thrive in extreme heat or cold, while others can survive under highly acidic or extremely salty conditions. Most bacteria that cause disease grow fastest in the temperature range between 41 and 135 degrees F. Microbial communities in high-temperature environments are often dominated by a few types of microorganisms and are often significantly less diverse than those in lower temperature habitats. Very high and low temperatures both obstruct the enzyme processes microorganisms depend on to survive. Temperatures below optimal will lead to a decrease in enzyme activity and slower metabolism, while higher temperatures can actually denature proteins such as enzymes and carrier proteins, leading to cell death. The ocean level is rising, glaciers are melting, CO2 in the air is increasing, forest and wildlife are declining, and water life is also getting disturbed due to climatic changes.
