Evidence The Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.

Climate change What causes climate change? Just as the world’s most respected scientific bodies have confirmed that the Earth is getting hotter, they have also stated that there is strong evidence that humans are driving the warming (2). Scientists agree the main cause of climate change is human activities which magnify the ‘greenhouse effect’ – a natural process in which gases in the atmosphere warm the Earth by trapping heat that is radiating towards space (2) (4). A layer of greenhouse gases, including water vapour and smaller amounts of carbon dioxide, methane and nitrous oxide, act as a thermal blanket surrounding the Earth. This absorbs heat and warms the surface to a life-supporting average of 15°C. As energy slowly escapes out of our atmosphere, some of it is absorbed by the greenhouses gases, which warms the Earth further.

15 Best Educational Resources Online The Internet revolution brought a lot of changes in the educational system. Instead of relying on textbooks, notebooks and other conventional classroom materials, students today rely on their tablets and smartphones, which carry a lot of potential for making the material more interactive and understandable. There are both free and paid online educational resources out there, though, with plenty to choose from. National Centers for Environmental Information (NCEI) IntroductionWarming ClimateHuman InfluenceMore Information Introduction Many lines of scientific evidence show the Earth's climate is changing. This page presents the latest information from several independent measures of observed climate change that illustrate an overwhelmingly compelling story of a planet that is undergoing global warming. It is worth noting that increasing global temperature is only one element of observed global climate change.

Thai Verbs Thai Verbs Learning the Thai Verbs is very important because its structure is used in every day conversation. The more you master it the more you get closer to mastering the Thai language. But first we need to know what the role of Verbs is in the structure of the grammar in Thai.

The climate crisis is already here – but no one’s telling us What is salient is not important. What is important is not salient. The media turns us away from the issues that will determine the course of our lives, and towards topics of brain-melting irrelevance.
