NASA: Climate Change and Global Warming. Global Warming: 2018 Articles, Facts, Causes & Effects. Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate. There is great debate among many people, and sometimes in the news, on whether global warming is real (some call it a hoax). But climate scientists looking at the data and facts agree the planet is warming.While many view the effects of global warming to be more substantial and more rapidly occurring than others do, the scientific consensus on climatic changes related to global warming is that the average temperature of the Earth has risen between 0.4 and 0.8 °C over the past 100 years.

Fossil fuel related carbon dioxide (CO2) emissions compared to five of the IPCC's "SRES" emissions scenarios. Global warming and climate change can both refer to the observed century-scale rise in the average temperature of the Earth's climate system and its related effects, although climate change can also refer to any historic change in climate.
Scientific understanding of the cause of global warming has been increasing. Climate model projections were summarized in the 2013 Fifth Assessment Report (AR5) by the IPCC. Observed temperature changes Temperature changes vary over the globe. Initial causes of temperature changes (external forcings) Global Warming News, Articles. Study warns of looming potential for runaway global warming. Facts on global warming, climate change and geospatial technologies.
Some Facts: The Rising Temperature April 2017 was the second-warmest April in 137 years of modern record-keeping, according to NASA‘s Goddard Institute for Space Studies (GISS).In 2016, Earth’s average surface temperature hit a record level for the third consecutive year since records began in 1880.The global average temperature was about 1.1 degree Celsius (1.98 Fahrenheit) higher than the pre-industrial era. This is when mankind’s mass burning of coal, and later oil and gas, started hiking levels of heat-trapping CO2 in the atmosphere. The Melting Ice Arctic summer sea ice shrank to 4.14 million square kilometers (1.6 million square miles) in 2016 — the second-lowest after 2012, when it reached 3.39 million km2.The Arctic Ocean could be ice-free in summer as early as 2030.On the other extreme of the world, Antarctica, sea ice last year hit its lowest extent ever recorded by satellites.

What Causes Global Warming? | Planetsave. Droughts, lengthy hot spells, heavy downpours, floods, and other extreme weather events are occurring more frequently and intensely every year. Around the world, research teams are analyzing these trends, noting the changes in temperature, rainfall, ice mass, sea level, and many other variables recorded by weather measuring devices.
The trends are undeniable: the Earth is getting warmer. Polar sea ice and glaciers are melting, the sea level is rising, and as the oceans absorb more and more carbon dioxide (CO2), they are becoming measurably more acidic. Why is this happening? Compiled by a team of over 300 experts from the most recent accumulation of data over three years, the 2014 National Climate Assessment (NCA), Climate Change Impacts in the United States, was required by Congress to provide clear answers to these important questions. The 2014 National Climate Assessment Image Notes: Separating Human From Natural Influences On Global Warming. The Critical Realities of Global Warming. What Is Global Warming? | Global Warming Facts. The globe is heating up. Both land and oceans are warmer now than record-keeping began in 1880, and temperatures are still ticking upward. This temperature rise, in a nutshell, is global warming. Here are the bare numbers, according to the National Oceanic and Atmospheric Administration (NOAA): Average surface temperatures rose a total of 1.71 degrees Fahrenheit (0.95 degrees Celsius) between 1880 and 2016.
The pace of change has been an additional 0.13 degrees F (0.07 degrees C) per decade, with the land surface warming faster than the ocean surface — 0.18 degrees F (0.10 degrees C) versus 0.11 degrees F (0.06 degrees C) per decade, respectively. The Paris Agreement, ratified by 159 nations as of the summer 2017, aims to halt that warming at 2.7 degrees F (1.5 degrees C) above Earth's average temperature during preindustrial times — a goal most scientists and policy makers agree will be a challenge to meet.
The main driver of today's warming is the combustion of fossil fuels. Global Warming 101 - Definition, Facts, Causes and Effects of Global Warming. Jump to Section Q: What is global warming? A: Here's a simple definition of global warming. (And yes, it's really happening.) Over the past 50 years, the average global temperature has increased at the fastest rate in recorded history. And experts see the trend is accelerating: All but one of the 16 hottest years in NASA’s 134-year record have occurred since 2000. Climate change deniers have argued that there has been a “pause” or a “slowdown” in rising global temperatures, but several recent studies, including a 2015 paper published in the journal Science, have disproved this claim.
Q: What causes global warming? A: Global warming occurs when carbon dioxide (CO2) and other air pollutants and greenhouse gases collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth’s surface. In the United States, the burning of fossil fuels to make electricity is the largest source of heat-trapping pollution, producing about two billion tons of CO2 every year.
What is global warming, facts and information? Glaciers are melting, sea levels are rising, cloud forests are dying, and wildlife is scrambling to keep pace. It has become clear that humans have caused most of the past century's warming by releasing heat-trapping gases as we power our modern lives. Called greenhouse gases, their levels are higher now than at any time in the last 800,000 years. We often call the result global warming, but it is causing a set of changes to the Earth's climate, or long-term weather patterns, that varies from place to place.
While many people think of global warming and climate change as synonyms, scientists use “climate change” when describing the complex shifts now affecting our planet’s weather and climate systems—in part because some areas actually get cooler in the short term. Climate change encompasses not only rising average temperatures but also extreme weather events, shifting wildlife populations and habitats, rising seas, and a range of other impacts.
Understanding the greenhouse effect. Global Warming. This page contains archived content and is no longer being updated. At the time of publication, it represented the best available science. Throughout its long history, Earth has warmed and cooled time and again. Climate has changed when the planet received more or less sunlight due to subtle shifts in its orbit, as the atmosphere or surface changed, or when the Sun’s energy varied. But in the past century, another force has started to influence Earth’s climate: humanity. What is Global Warming? Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released by people burning fossil fuels. How Does Today’s Warming Compare to Past Climate Change?
Earth has experienced climate change in the past without help from humanity. Why Do Scientists Think Current Warming Isn’t Natural? In Earth’s history before the Industrial Revolution, Earth’s climate changed due to natural causes unrelated to human activity. Global Warming and Its Effects | Global Events | USA | Europe | Middle East | Asia Pacific. Effects of global warming. Describes the effects created by global warming A 2014 summary of climate change impacts 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. The effects of global warming or climate damage include far-reaching and long-lasting changes to the natural environment, to ecosystems and human societies caused directly or indirectly by human emissions of greenhouse gases.
It also includes the economic and social changes which stem from living in a warmer world. Climate change has already impacted ecosystems and humans as well. In combination with climate variability, it makes food insecurity worse in many places and puts pressure on fresh water supply. This in combination with extreme weather events, leads to negative effects on human health. Observed and future warming Projected global warming in 2100 for a range of emission scenarios. Effects | Facts. › en español Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner. Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves.
Taken as a whole, the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time. Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities. The Intergovernmental Panel on Climate Change (IPCC), which includes more than 1,300 scientists from the United States and other countries, forecasts a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century.
