Attribution of recent climate change In this article, " climate change " means a change in climate that persists over a sustained period of time. Changes in climate may be due to natural causes, e. Detection does not imply attribution of the detected change to a particular cause.
NASA GISS The graph above shows the average of a set of temperature simulations for the 20th century black linefollowed by projected temperatures for the 21st century based on three greenhouse gas emissions scenarios colored lines. This projection is relative to global temperatures at the end of the 20th century.
Global surface temperature for the past 5. The lastyears are expanded in the lower half of the figure image credit: Physical impacts of climate change Seven of these indicators would be expected to increase in a warming world and observations show that they are, in fact, increasing.
Three would be expected to decrease and they are, in fact, decreasing.
Each of the different colored lines in each panel represents an independently analyzed set of data. The data come from many different technologies including weather stationssatellitesweather balloonsships and buoys.
Some of the graphs show a positive trende. Other graphs show a negative trend, e.

Evidence of warming is also apparent in living biological systems. With medium confidence see footnote 1IPCC  concluded that human influences had contributed to an increase in heavy precipitation events at the global scale.
Projections of future changes in precipitation show overall increases in the global average, but with substantial shifts in where and how precipitation falls.
Extremely hot nights have doubled in frequency. The area in which extremely hot summers are observed, has increased fold. These changes are not explained by natural variability, and attributed by climate scientists to the influence of anthropogenic climate change.
Heat waves with high humidity pose a big risk to human health while heat waves with low humidity lead to dry conditions that increase wildfires. The mortality from extreme heat is larger than the mortality from hurricanes, lightning, tornadoes, floods, and earthquakes together  See also heat wave.

These are the first detections of this astrophysically important line from galaxies line emission. Since the [OIII] 88 µm line.
Tropical cyclones At the global scale, the frequency of tropical cyclones will probably decrease or be unchanged. Some impacts will be beneficial—e. Retreat of glaciers since A map of the change in thickness of mountain glaciers since Thinning in orange and red, thickening in blue.
A map that shows ice concentration on 16 Septemberalong with the extent of the previous record low yellow line and the mid-September median extent black line setting a new record low that was 18 percent smaller than the previous record and nearly 50 percent smaller than the long-term — average.
The cryosphere is made up of areas of the Earth which are covered by snow or ice. Assuming high growth in greenhouse gas emissions SRES A2some models projected that Arctic sea ice in the summer could largely disappear by the end of the 21st century.
Effects of global warming on oceans The role of the oceans in global warming is complex. The oceans serve as a sink for carbon dioxide, taking up much that would otherwise remain in the atmosphere, but increased levels of CO 2 have led to ocean acidification. Furthermore, as the temperature of the oceans increases, they become less able to absorb excess CO 2.
The ocean have also acted as a sink in absorbing extra heat from the atmosphere. Ongoing effects include rising sea levels due to thermal expansion and melting of glaciers and ice sheets, and warming of the ocean surface, leading to increased temperature stratification.Characterizing Transiting Planet Atmospheres through N.
B. Cowan 1, T. Greene 2, D. Angerhausen 3, the vast majority of planets are extrasolar. This means that the most extreme worlds, and those most like the Earth, are exoplanets.
while measurements of thermal emission constrain vertical and horizontal temperature structure. An international group of astronomers have carried out multi-wavelength observations of HESS J+ and found evidence supporting the hypothesis .
Climate change is now a major concern. The polar ice caps are reported to be melting and sea levels are rising due to an increase in the average temperature of the Earth’s atmosphere and regardbouddhiste.com warming is driven by increasing levels of tropospheric gases that contribute to .
The Institute of Physics (IOP) is a leading scientific society promoting physics and bringing physicists together for the benefit of all.
It has a worldwide membership of around 50 comprising physicists from all sectors, as well as those with an interest in physics. A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic regardbouddhiste.com term "laser" originated as an acronym for "light amplification by stimulated emission of radiation".
The first laser was built in by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur.
