In-depth details on the 2, satellites currently orbiting Earth, including their country of origin, purpose, and other operational details. Published Dec 8, Updated Apr 1, Assembled by experts at the Union of Concerned Scientists UCS , the Satellite Database is a listing of the more than operational satellites currently in orbit around Earth. Our intent in producing the database is to create a research tool for specialists and non-specialists alike by collecting open-source information on operational satellites and presenting it in a format that can be easily manipulated for research and analysis. It is available as both a downloadable Excel file and in a tab-delimited text format. A version is also provided in which the “Name” column contains only the official name of the satellite in the case of government and military satellites, and the most commonly used name in the case of commercial and civil satellites. The database is updated three times a year. The database contains 28 types of data for each satellite, including technical information about each satellite mass, power, launch date, expected lifetime and its orbit apogee, perigee, inclination, and period , as well as information on what the satellite is used for, and who owns, operates, and built the satellite. We welcome corrections, additions, and suggestions.

Models that account only for the effects of natural processes are not able to explain the warming observed over the past century. Models that also account for the greenhouse gases emitted by humans are able to explain this warming. Click the image to view a larger version. When incoming energy from the sun is absorbed by the Earth system, Earth warms.

When absorbed energy is released back into space, Earth cools. This record shows that the climate system varies naturally over a wide range of time scales. In general, climate changes prior to the Industrial Revolution in the s can be explained by natural causes, such as changes in solar energy, volcanic eruptions, and natural changes in greenhouse gas GHG concentrations. Recent climate changes, however, cannot be explained by natural causes alone. Research indicates that natural causes do not explain most observed warming, especially warming since the mid th century.

Rather, it is extremely likely that human activities have been the dominant cause of that warming. Radiative forcing is a measure of the influence of a particular factor e.

Why is it necessary and even vital to maintain the global temperature increase below 1. Adaptation will be less difficult. Our world will suffer less negative impacts on intensity and frequency of extreme events, on resources, ecosystems, biodiversity, food security, cities, tourism, and carbon removal. Summary : The impacts of climate change are being felt in every inhabited continent and in the oceans. However, they are not spread uniformly across the globe, and different parts of the world experience impacts differently.

An average warming of 1. Limiting warming to 1. The consequences of temporarily overshooting 1. The size and duration of an overshoot will also affect future impacts. Temperatures are not changing at the same speed everywhere, however: warming is strongest on continents and is particularly strong in the Arctic in the cold season and in mid-latitude regions in the warm season.

This is due to self-amplifying mechanisms, for instance due to snow and ice melt reducing the reflectivity of solar radiation at the surface, or soil drying leading to less evaporative cooling in the interior of continents. This means that some parts of the world have already experienced temperatures greater than 1. This would be the case even if the global warming is held at 1. It would also lead to an increase in heavy rainfall events in some regions, particularly in the high latitudes of the Northern Hemisphere, potentially raising the risk of flooding.

The term Global Warming refers to the observation that the atmosphere near the Earth’s surface is warming. This warming is one of many kinds of climate change that the Earth has gone through in the past and will continue to go through in the future. It is reasonable to expect that the Earth should warm as the amount of greenhouse gases in the atmosphere increases.

It is known for certain that atmospheric concentrations of greenhouse gases are rising dramatically due to human activity. It is less well known exactly how the increases in these greenhouse gases factor in the observed changes of the Earth’s climate and global temperatures. The Earth’s climate changes when the amount of energy stored by the climate system is varied.

The most significant changes occur when the global energy balance between incoming energy from the Sun and outgoing heat from the Earth is upset.

The origin of smallpox is unknown. Smallpox is thought to date back to the Egyptian Empire around the 3 rd century BCE Before Common Era , based on a smallpox-like rash found on three mummies.

But a few malcontents within the Church pointed out that the Bible speaks of ‘the four corners’ of the earth.
