What can one person, or even one nation, do on their own to slow and reverse climate change? But just as ecologist Stephen Pacala and physicist Robert Socolow, both at Princeton University, came up with 15 so-called " wedges " for nations to utilize toward this goal—each of which is challenging but feasible and, in some combination, could reduce greenhouse gas emissions to safer levels —there are personal lifestyle changes that you can make too that, in some combination, can help reduce your carbon impact. Not all are right for everybody. Some you may already be doing or absolutely abhor.
Examines the science and arguments of global warming skepticism. Common objections like 'global warming is caused by the sun', 'temperature has changed naturally in the past' or 'other planets are warming too' are examined to see what the science really says. Sir David Attenborough: The Truth About Climate Change, October 22, As well as the links above, see also Skeptical Science, which, while examining the arguments of global warming skepticism, provides information on causes of anthropogenic global warming.. Doesn’t recent record cold weather disprove Global Warming? The race to find a solution to a rapidly warming world is one of the most pressing challenges facing our planet. One proposal to try to halt this warming is literally out-of-this-world: a giant.
Scientists should always challenge themselves to improve their understanding. This website gets skeptical about global warming skepticism.
Do their arguments have any scientific basis? What does the peer reviewed scientific literature say? Carbon emissions from this perennially frozen land have the potential to reinforce global warming. Adding to this risk, the Arctic is also pockmarked by millions of small ponds and lakes, formed as the frozen soil thaws, collapses and fills with melted ice, snow and rain.
These lakes accelerate thawing of the surrounding land, ramping up how much carbon the land emits.
And our findings suggest this rapid thaw has the potential to double how much permafrost carbon is released this century. Giant freezer Permafrost covers around a quarter of the non-glaciated land in the northern hemisphere, including large parts of Siberia, Alaska, northern Canada and the Tibetan plateau.
Permafrost soils lock in old plant and animal remains like a giant freezer.
This a carbon-rich combination of roots, leaves and peat that covered the vast tundra-steppe and interspersed wetlands of the last ice age. This layer is, perhaps, just a few tens of centimetres deep.
However, a warming climate puts an increasing amount of permafrost at risk of thawing.We Need Your Support to Make Change Happen. We can reduce global warming emissions and ensure communities have the resources they need to withstand the effects of climate change—but not without you.
Your generous support helps develop science-based solutions for a healthy, safe, and sustainable future. Examines the science and arguments of global warming skepticism.

Ivar Giaever, a Nobel Prize-Winner for physics in , declared his dissent on man-made global warming claims at a Nobel forum on July 1, “I would say that basically global warming is a non-problem,” Dr. Giaever announced during his speech titled “Global Warming Revisited.
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 . Global Warming, the general increase in the earth's near-surface air and ocean temperatures, remains a pressing issue in a society that has expanded its industrial use since the mid-twentieth century.
