One side argues that the current global warming is caused by human factors while the other side insists it is occurring because of natural forces. In the latter argument, two natural causes that dominate the conversation are solar changes and changes to the Earth’s orbit.
Scientific concerns about global warming grew during the 1980s, and in 1988 (a year when North America faced an intense heat wave and drought) these spilled over into political concerns, and the WMO and the United Nations Environment Programme (UNEP) established the International Panel on Climate Change (IPCC) to …
The chief benefits of global warming include: fewer winter deaths; lower energy costs; better agricultural yields; probably fewer droughts; maybe richer biodiversity.
Human activity is the main cause of climate change. People burn fossil fuels and convert land from forests to agriculture. … Burning fossil fuels produces carbon dioxide, a greenhouse gas. It is called a greenhouse gas because it produces a “greenhouse effect”.
Studying the climate helps us predict how much rain the next winter might bring, or how far sea levels will rise due to warmer sea temperatures. We can also see which regions are most likely to be affected by extreme weather, or which wildlife species are threatened by climate change.
By around 2000, some predicted, an unprecedented global warming would become apparent. Their worries first caught wide public attention in the summer of 1988, the hottest on record till then. (Most since then have been hotter.)
Climate change describes a change in the average conditions — such as temperature and rainfall — in a region over a long period of time. NASA scientists have observed Earth’s surface is warming, and many of the warmest years on record have happened in the past 20 years.
Temperatures are rising world-wide due to greenhouse gases trapping more heat in the atmosphere. Droughts are becoming longer and more extreme around the world. Tropical storms becoming more severe due to warmer ocean water temperatures.
Climate change describes a change in the typical weather for a region — such as high and low temperatures and amount of rainfall — over a long period of time. Scientists have observed that, overall, Earth is warming. In fact, many of the warmest years on record have happened in the past 20 years.
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.
Climate change is having serious impacts on the world’s water systems through more flooding and droughts. Warmer air can hold a higher water content, which makes rainfall patterns more extreme. Rivers and lakes supply drinking water for people and animals and are a vital resource for farming and industry.
The earth’s climate is influenced and changed through natural causes like volcanic eruptions, ocean currents, the Earth’s orbital changes, solar variations and internal variability.
One of the most pressing issues of our time, climate change threatens the lives and livelihoods of billions of people. Natural disasters, environmental degradation and extreme weather patterns disrupt harvests, deplete fisheries, erode livelihoods and spur infectious diseases.
Firstly, we must stop deforestation in all forms. Do not cut down more trees as it will only worsen the level of carbon dioxide in the air. Instead, encourage people to plant even more trees to create a fine balance in nature. Moreover, it reduces the usage of energy everywhere.
Humans are increasingly influencing the climate and the earth’s temperature by burning fossil fuels, cutting down forests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.
Climate change may aggravate erosion, decline in organic matter, salinization, soil biodiversity loss, landslides, desertification and flooding. The effect of climate change on soil carbon storage can be related to changing atmospheric CO2 concentrations, increased temperatures and changing precipitation patterns.
