Trees help to regulate the climate by absorbing CO2 from the atmosphere. Others are human-produced, like growing and harvesting crops, musical rhythms or economic cycles. Volcanic Eruptions – When sulphur and ash is spurted out the vent during the eruption, they rise high into the atmosphere and reflect heat from the sun, having a cooling effect. Climate change is one of the biggest issues affecting the world today. Global warming will cause further changes that are likely to create further heating. The United Nations Environment Programme (Unep) is … The atmosphere allows the heat from the Sun (short-wave radiation) to pass through to heat the Earth's surface. Any factor that causes a sustained change to the amount of incoming energy or the amount of outgoing energy can lead to climate change. The ozone layer, which lies high up in the atmosphere, shields us from harmful ultraviolet (UV) rays that come from the Sun. Greenhouse gas emission is a major human causes of climate change, and their sources include transportation, electricity production, burning fossil fuel in industries, commercial and residential application, agriculture, and land use. If they are cut down, there will be higher amounts of carbon dioxide in the atmosphere. IN THE NEWS Mayor quashes £25 C-charge hike.

The American pika, for example, is a small mammal that lives in cool mountainous areas in western North America—in fact, it can die when exposed to temperatures warmer than 78˚F.So as the mountain climate heats up, the pika climbs the slopes in search of cooler habitat. We know that climate change is happening – but there are plenty of things individuals can do to help mitigate it. 1. A hefty slice of global greenhouse gas emissions come from the burps and farts of livestock. The energy changes spread out around the globe upsetting climate processes. These volcanic materials reflect incoming radiation back out to space cooling the Earth. The BBC has accepted it gets coverage of climate change “wrong too often” and told staff: “You do not need a ‘denier’ to balance the debate.”. How distinct climate zones can be identified in different parts of the world. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming. Another group of greenhouse gases includes the chlorofluorocarbons (CFCs). At the UN climate summit in Copenhagen, 192 governments are aiming for a new global agreement to constrain greenhouse gas emissions and curb human-induced climate change. This led to the River Thames in London freezing solid in the winter months.
