Two millennia of mean surface temperatures according to different reconstructions from climate proxieseach smoothed on a decadal scale, with the instrumental temperature record overlaid in black. Multiple independently produced datasets confirm that from to the global average land and ocean surface temperature increased by 0. The rest has melted ice and warmed the continents and the atmosphere. Cold blob North Atlantic Difference between average temperature in — compared to the period, showing strong arctic amplification.
Created by Skeptical Science Our climate is absorbing a lot of heat. When scientists add up all of the Globe warming warming the oceans, land, and atmosphere and melting the ice, they find our climate is accumulating 4 Hiroshima atomic bombs worth of heat every Globe warming.
This warming is due to more heat-trapping greenhouse gases in the atmosphere. The burning of fossil fuels means we are emitting billions of tonnes of carbon dioxide every year. This is the main contributor to global warming. To communicate the sheer amount of heat our planet is accumulating, we have created this widget, embeddable on blogs and also available as a Facebook app, an iPad app, and an iPhone app.
To help get the word out on just how much global warming our planet is experiencing, add the widget to your own blog or use the widget on Facebook, like it and share it.
The app is not available through the Apple App Store. Accumulating Heat The earth has warmed rapidly over the past century due mainly to human activity, and especially over the past few decades.
Several Skeptical Science contributors worked together to publish a scientific paper 1 which combined the land, air, ice, and ocean warming data.
It found that for recent decades the earth has been heating at a rate of trillion Joules per second. This widget attempts to put that heating into terms that are easier to visualize.
Detonating four Hiroshima atomic bombs per second Experiencing two Hurricane Sandys per second Enduring four 6. Increases in the temperatures that people experience day to day are only one of several reservoirs for accumulating heat.
Changes in the ocean, where most of the heat is going, have been more steady, while the melting of vast stores of ice is accelerating.
The earth continues to warm, day after day, at a concerning rate. Learn More About Heat in the Life on earth is made possible by greenhouse gases. Like visible light, infrared radiation passes through the atmosphere and into space.
But small traces of greenhouse gases, such as carbon dioxide, are not transparent to infrared radiation. They absorb and re-emit that energy, trapping some of that heat within the atmosphere.
Back Climate Changes Changes in the climate are visible all around us. Some are subtle and seemingly inconsequential, but these changes are accelerating and undeniable. Tree lines and species are migrating poleward and upward. Glaciers and Arctic ice are retreating at an alarming rate 4.
Sea levels are rising 5. Every day, more and more studies point towards a changing and warming world in new and sometimes unexpected ways. Back Climate Change Fingerprints The indicators that recent climate change is the result of burning fossil fuels, rather than from some unknown natural variation, are clear and consistent with what we do know.
There are subtle differences to how the world will warm due to greenhouse gases compared with other potential sources such as an increase in the warmth of the sun. Most importantly, scientists know that greenhouse gases would cause the upper atmosphere to cool rather than warm.
We also know that the source of the additional carbon dioxide in the atmosphere is due to burning fossil fuels.31, American scientists have signed this petition, including 9, with PhDs For information about this project, click on the appropriate box below. Global warming is happening now. The planet's temperature is rising.
The trend is clear and unmistakable. Every one of the past 40 years has been warmer than the 20th century average. was the hottest year on record.
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.
Many of the observed changes since the s are unprecedented in the instrumental temperature record, and in paleoclimate proxy records of climate. The title of the book "Global Warming - The Complete Briefing" is aptly named, as it is an excellent briefing, or primer, on the subject of global warming.
