Effects of Global Warming
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. Human caused climate change is one of the threats to sustainability. Many physical impacts of global warming are already visible, including extreme weather events, glacier retreat, changes in the timing of seasonal events (e.g., earlier flowering of plants), sea level rise, and declines in Arctic sea ice extent. The future impact of global warming depends on the extent to which nations implement prevention efforts and reduce greenhouse gas emissions. Ocean acidification is not a consequence of global warming, but instead has the same cause: increasing atmospheric carbon dioxide. 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. Rising temperatures threaten development because of negative effects on economic growth in developing countries. The social impact of climate change will be further affected by society's efforts to prepare and adapt. Global warming already contributes to migration in different parts of the world. Near-term climate change policies significantly affect long-term climate change impacts. Stringent mitigation policies might be able to limit global warming (in 2100) to around 2 °C or below, relative to pre-industrial levels. Without mitigation, increased energy demand and extensive use of fossil fuels might lead to global warming of around 4 °C. Higher magnitudes of global warming would be more difficult to adapt to, and would increase the risk of negative impacts.

Foolishness for Christ
Foolishness for Christ (Greek: διά Χριστόν σαλό, Template:Lang-cu) refers to behavior such as giving up all one's worldly possessions upon joining a monastic order, or to deliberate flouting of society's conventions to serve a religious purpose–particularly of Christianity. Such individuals have historically been known as both "holy fools" and "blessed fools". The term "fool" connotes what is perceived as feeblemindedness, and "blessed" or "holy" refers to innocence in the eyes of God. The term fools for Christ derives from the writings of Saint Paul. Desert Fathers and other saints acted the part of Holy Fools, as have the yurodivy (or iurodstvo) of Eastern Orthodox asceticism. Fools for Christ often employ shocking and unconventional behavior to challenge accepted norms, deliver prophecies, or to mask their piety. Parallels for this type of behavior exist in non-Christian traditions as well. The Avadhuta (Sanskrit), for example, the Islamic tradition of Qalandariyya and Malamatiyya Sufism and other crazy-wise mystics display similar traits. Nasreddin, of the Sufis, is also an example.

Northover Projector
The Projector, 2.5 inch—more commonly known as the Northover Projector—was an ad hoc anti-tank weapon used by the British Army and Home Guard during the Second World War. With a German invasion of Great Britain seeming likely after the defeat in the Battle of France, most available weaponry was diverted to the regular British Army, leaving the Home Guard short on supplies, particularly anti-tank weaponry. The Northover Projector was designed by Home Guard officer Robert Harry Northover to act as a makeshift anti-tank weapon, and was put into production in 1940 following a demonstration to the Prime Minister, Winston Churchill. The weapon consisted of a hollow metal tube attached to a tripod, with a rudimentary breech at one end. Rounds were fired with the use of black powder ignited by a standard musket percussion cap, and it had an effective range of between 100 and 150 yards. Although it was cheap and easy to manufacture, it did have several problems; it was difficult to move and the No. 76 Special Incendiary Grenades it used as one type of ammunition had a tendency to break inside the breech, damaging the weapon and injuring the crew. Production began in late 1940, and by the beginning of 1943 nearly 19,000 were in service. Like many obsolete Home Guard weapons, it was eventually replaced by other weapons, such as the 2-pounder anti-tank gun.

Weddell Island
Weddell Island (Spanish: Isla San José) is one of the Falkland Islands in the South Atlantic, lying off the southwest extremity of West Falkland. It is situated 1,545 km (960 mi) west-northwest of South Georgia Island, 1,165 km (724 mi) north of Livingston Island, 606 km (377 mi) northeast of Cape Horn, 358 km (222 mi) northeast of Isla de los Estados, and 510 km (320 mi) east of the Atlantic entrance to Magellan Strait. With an area of 265.8 km2 (102.6 sq mi) Weddell is the third largest island in the archipelago after East Falkland and West Falkland, and one of the largest private islands in the world. It has only one inhabited location, Weddell Settlement, with a single digit population engaged in sheep farming and tourism services. The island offers walks to wildlife watching sites and scenery destinations including some spectacular landscapes featuring the famous Falklands stone runs. Weddell is both an Important Plant Area and a priority Key Biodiversity Area. It is a remote place, infrequently visited by a resupply ship and occasionally by private yachts, accessible by air with a short (some 200 km (120 mi)) if expensive flight from the Falklands capital, Stanley.

Heaviest Trains
The heaviest trains in the world are freight trains hauling bulk commodities such as coal and iron ore. The weight of trains generally does not include the weight of the operating locomotives; this is not considered dead weight, so is not included. If for example a train had two locomotives operating and was simply hauling a third off line, this third locomotive would be included in the payload weight.

Constraints Accounting
Constraints accounting (CA) allow some variations generally accepted accounting principles(GAAP) when reporting financial statements of company and these variations do not violate the GAAP in light of recognised CA. CA contains explicit consideration of the role of constraints in accounting and constraints relate to limitations when providing financial information. The definition of a constraint is a regulation which belongs to prescribed bounds and there are four main types of constraints which are the cost-benefit relationship, materiality, industry practices, and conservatism, and these constraints are also accounting guidelines which border the hierarchy of qualitative information.

King Cherry
King cherry (Cerasus × nudiflora, 왕벚 wangbeoj, 왕벚나무 wangbeojnamu or 왕벚꽃 wangbeojkkoch) is a Korean native cherry tree originated from Jeju Island. It is a distinct species from Japanese native Yoshino cherry. King cherry is a rare plant and listed as an endangered species. As of April 2017, 194 King cherry trees were growing around Mt. Halla in Jeju Island. According to Gen-ichi Koidzumi, King cherry is erroneously believed to be discovered by a French missionary Emile Taquet although what he discovered was a different species. There have been disputes over the origin of king cherry and Yoshino cherry. In 2007, a study conducted on the comparison of king cherry and Yoshino cherry concluded that these trees were categorized as distinct species. However, South Korean media assert that King cherry is the same species as Yoshino cherry. In Korea most of the places for cherry blossom festivals, including Yeouido and Jinhae, are still planted with Japanese Yoshino cherry trees.

Disability in Israel
Disability rights in Israel are based among the rest upon disabillity pensions, accessibility regulations, therapy, special education, sheltered workshop and assisted living. Since the beginning of the 21st century, the disabled people in Israel, with a population of 250,000, have managed to equalize the disability pension from the Bituah Leumi (National Insurance Institute of Israel) to the minimum wage level in Israel. As of 2017, the struggle was made by demonstrations, blocking main roads, highways and industries, activity in social networking services, petitions to the High Court of Justice, negotiations with the Government of Israel and bills in the Knesset. In 2017, a full disability pension was 2,342 ILS. The minimum wage in this year was 5,000 ILS, and in December 2017 it went up to 5,300 ILS per month.
