The blue uncertainty bars show a 9. Global warming, also referred to as climate change, is the observed century scale rise in the average temperature of the Earths climate system and its related effects. Multiple lines of scientific evidence show that the climate system is warming. Many of the observed changes since the 1. In 2. 01. 3, the Intergovernmental Panel on Climate Change IPCC Fifth Assessment Report concluded that It is extremely likely that human influence has been the dominant cause of the observed warming since the mid 2. The largest human influence has been the emission of greenhouse gases such as carbon dioxide, methane and nitrous oxide. Climate model projections summarized in the report indicated that during the 2. C 0. 5 to 3. 1 F in the lowest emissions scenario, and 2. C 4. 7 to 8. 6 F in the highest emissions scenario. These findings have been recognized by the national science academies of the major industrialized nations9a and are not disputed by any scientific body of national or international standing. Special Article. Shattuck Lecture. Cardiovascular Medicine at the Turn of the Millennium Triumphs, Concerns, and Opportunities. Eugene Braunwald, M. D. Knowledge of the molecular and cellular events in heat stroke has advanced steadily during the past decade. It is now known that heat stroke is associated with injury. Conduction Heat Transfer Schneider Pdf MergerFuture climate change and associated impacts will differ from region to region around the globe. Anticipated effects include increasing global temperatures, rising sea levels, changing precipitation, and expansion of deserts in the subtropics. Warming is expected to be greater over land than over the oceans and greatest in the Arctic, with the continuing retreat of glaciers, permafrost and sea ice. Other likely changes include more frequent extreme weather events such as heat waves, droughts, heavy rainfall with floods and heavy snowfall 1. Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels. Because the climate system has a large inertia and greenhouse gases will remain in the atmosphere for a long time, many of these effects will persist for not only decades or centuries, but for tens of thousands of years to come. Possible societal responses to global warming include mitigation by emissions reduction, adaptation to its effects, building systems resilient to its effects, and possible future climate engineering. Most countries are parties to the United Nations Framework Convention on Climate Change UNFCCC,2. Parties to the UNFCCC have agreed that deep cuts in emissions are required2.

A global 2. 01. 5 Pew Research Center report showed that a median of 5. Significant regional differences exist, with Americans and Chinese whose economies are responsible for the greatest annual CO2 emissions among the least concerned. Observed temperature changes.

In the period from 1. Earths average surface temperature rose by 7. C. The rate of warming almost doubled in the last half of that period 7. C per decade, against 7. C per decade. 2. Although the popular press often reports the increase of the average near surface atmospheric temperature as the measure of global warming, most of the additional energy stored in the climate system since 1. The rest has melted ice and warmed the continents and the atmosphere. Since 1. 97. 9, the average temperature of the lower troposphere has increased between 0. C 0. 2. 16 and 0. F per decade, satellite temperature measurements confirm. Climate proxies show the temperature to have been relatively stable over the one or two thousand years before 1. Medieval Warm Period and the Little Ice Age. The warming evident in the instrumental temperature record is consistent with a wide range of observations, as documented by many independent scientific groups. Examples include sea level rise,3. The probability that these changes could have occurred by chance is virtually zero. Regional trends and short term fluctuations. Temperature increases vary a lot across the globe. Since 1. 97. 9, land temperatures have increased about twice as fast as ocean temperatures 7. C per decade against 7. Head Start Program Goal more. C per decade. 3. Ocean temperatures increase more slowly than land temperatures because of the larger effective heat capacity of the oceans and because oceans lose more heat by evaporation. Since the beginning of industrialisation in the eighteenth century, the temperature difference between the hemispheres has increased due to melting of sea ice and snow in the North. In the past one hundred years, average arctic temperatures have been increasing at almost twice the rate of the rest of the world however, arctic temperatures are also highly variable. Although more greenhouse gases are emitted in the Northern than in the Southern Hemisphere, this fact does not contribute to the difference in warming because the major greenhouse gases persist long enough to diffuse within as well as between the hemispheres. The thermal inertia of the oceans and the slow responses of other indirect effects occasion the climate to take centuries or longer to adjust to past changes in forcings. One climate commitment study concluded that if greenhouse gases were stabilized at year 2. Celsius,4. 2 and another found that if they were stabilized at 2. Celsius. Some of this surface warming will be driven by past natural forcings which are still seeking equilibrium in the climate system. One study using a highly simplified climate model indicates these past natural forcings may account for as much as 6. Global temperature is subject to short term fluctuations that overlay long term trends and can temporarily mask them. The relative stability in surface temperature from 2. Warmest years vs. Sixteen of the seventeen warmest years on record have occurred since 2. While record breaking years attract considerable public interest, individual years are less significant than the overall trend. Some climatologists have criticized the attention that the popular press gives to warmest year statistics. In particular, ocean oscillations such as the El Nio Southern Oscillation ENSO can cause temperatures of a given year to be abnormally warm or cold for reasons unrelated to the overall trend of climate change. Gavin Schmidt stated the long term trends or the expected sequence of records are far more important than whether any single year is a record or not. Initial causes of temperature changes external forcingsCO2 concentrations over the last 4. Greenhouse effect schematic showing energy flows between space, the atmosphere, and Earths surface. Energy exchanges are expressed in watts per square metre Wm. By itself, the climate system may generate random changes in global temperatures for years to decades at a time, but long term changes emanate only from so called external forcings. These forcings are external to the climate system, but not necessarily external to Earth.
