Global waming

Extreme weather Another impact of global warming: Fall and winter ice in the Arctic hit record lows in both andmeaning the ice expanse did not cover as much of the open sea as previously observed. Biosphere Overall, it is expected that climate change will result in the extinction of many species and reduced diversity of ecosystems.

Some climatologists have criticized the attention that the popular press gives to "warmest year" statistics.

Global Warming: News, Facts, Causes & Effects

However, we can answer the question of how unusual MGW is. Greenhouse gases Since the beginning of the industrial revolution, humans have been rapidly changing the balance of gases in the atmosphere.

They exert a cooling effect by increasing the reflection of incoming sunlight. There are several big ways climate change can and will affect the globe: The main driver, the researchers found, is the increasing evaporation of water from hotter and hotter soil.

It is proposed that the increase Global waming the logarithm of CO2 is causing the increase in temperature, yet the curves diverge. Tsunamis could be generated by submarine landslides caused by warmer ocean water thawing ocean-floor permafrost or releasing gas hydrates.

MGW is not unusual by Holocene standards in its amplitude, duration, and timing. The observed widespread glacial retreat in the past — years requires additional forcing outside the realm of natural changes for their explanation. If models are not capable of simulating this natural warming, of millennial cyclic origin, then the models must be wrong, and our knowledge of climate change insufficient.

What Is Global Warming?

Encyclopedia of Paleoclimatology and Ancient Environments pp. Climate change feedbackClimate sensitivityand Arctic amplification The dark ocean surface reflects only 6 percent of incoming solar radiation, whereas sea ice reflects 50 to 70 percent.

Other factors being equal, a higher climate sensitivity means that more warming will occur for a given increase in greenhouse gas forcing. Global warming has led to decades of shrinking and thinning in a warm climate that has put the Arctic sea ice in a precarious position, it is now vulnerable to atmospheric anomalies.

Models simulate global cooling without anthropogenic forcing. There is great concern than this and other human actions deforestation, cattle raising, and changes in land use might have an important impact over climate, precipitating an abrupt climate change.

As with all guest posts please keep your comments civil and relevant. The treeline represents the limit where climatic conditions allow the establishment of new trees. The reasons for this are unclear, and not discussed often in the scientific literature. Running nine-year trends in surface warming.

Uniform variation in sea level during Modern Global Warming Sea level rise SLRis one of the main consequences of MGW as it is driven mainly by the addition of water from melting of the cryosphere, and thermal expansion of the warming oceans steric SLR.

However, two dangers should be avoided when dealing with the global temperature anomaly.

Costly and Growing Health Impacts Climate change has significant implications for our health, including increased air pollution and a longer and more intense allergy season.

Parker and Ollier, “The Global Historical Climatology Network (GHCN) v2 temperature time series (GISS Surface Temperature Analysis, ) in Alice Spring and all the 36 other stations located in a circle of 1, km from Alice Spring do not show any are stations covering different time windows having very close patterns of temperatures.

The House is expected to vote this week on expressing the sense of Congress that a carbon tax is detrimental to the U.S. economy. The House passed. Sep 12,  · Vital Signs of the Planet: Global Climate Change and Global Warming. Current news and data streams about global warming and climate change from NASA.

Global warming, also referred to as climate change, is the observed century-scale rise in the average temperature of the Earth's climate system and its related effects. Multiple lines of scientific evidence show that the climate system is warming.
