essay on climate change wikipedia

Many climate change impacts have been felt in recent years, with 2023 the warmest on record at +1.48 °C (2.66 °F). Additional warming will increase these impacts and can trigger tipping points, such as melting all of the Greenland ice sheet. Under the 2015 Paris Agreement, nations collectively agreed to keep warming "well under 2 °C".However, with pledges made under the Agreement, global ...

The history of the scientific discovery of climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect was first identified. In the late 19th century, scientists first argued that human emissions of greenhouse gases could change Earth's energy ...

Climate change is the long-term alteration of temperature and typical weather patterns in a place. Climate change could refer to a particular location or the planet as a whole. Climate change may cause weather patterns to be less predictable. These unexpected weather patterns can make it difficult to maintain and grow crops in regions that rely ...

Climate change is the climate of Earth changing. The Earth's climate has been much hotter and colder than it is today. [1] Climate change this century and last century is sometimes called global warming, because the average temperature on the surface has risen. [1] The last decade (2011-2020) was the warmest on record, and each of the last ...

Climate change is a long-term change in the average weather patterns that have come to define Earth's local, regional and global climates. These changes have a broad range of observed effects that are synonymous with the term. Changes observed in Earth's climate since the mid-20th century are driven by human activities, particularly fossil fuel burning, […]

Average global temperatures have increased by 2.2 degrees Fahrenheit, or 1.2 degrees Celsius, since 1880, with the greatest changes happening in the late 20th century. Land areas have warmed more ...

The United Nations Framework Convention on Climate Change (UNFCCC) is the UN process for negotiating an agreement to limit dangerous climate change.Formally it is an international treaty among countries to combat "dangerous human interference with the climate system", in part by stabilizing greenhouse gas concentrations in the atmosphere. It was signed in 1992 by 154 states at the United ...

Scientists predict that it is highly likely that the rainfall patterns we all need for clean, fresh water will change, drying up in some places while causing floods in others. There is also significant evidence that, as a result of climate change, wildfires will worsen, destroying lives and property; that sea levels will rise, flooding many ...

Global warming, the phenomenon of rising average air temperatures near Earth's surface over the past 100 to 200 years. Although Earth's climate has been evolving since the dawn of geologic time, human activities since the Industrial Revolution have a growing influence over the pace and extent of climate change.

Climate Explained, a part of Yale Climate Connections, is an essay collection that addresses an array of climate change questions and topics, including why it's cold outside if global warming is real, how we know that humans are responsible for global warming, and the relationship between climate change and national security.

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 ...

Climate change refers to long-term shifts in temperatures and weather patterns. Such shifts can be natural, due to changes in the sun's activity or large volcanic eruptions. But since the 1800s ...

13.1 Strengthen resilience and adaptive capacity to climate-related hazards and natural disasters in all countries 13.2 Integrate climate change measures into national policies, strategies and ...

Climate change - Evidence, Causes, Impacts: All historical sciences share a problem: As they probe farther back in time, they become more reliant on fragmentary and indirect evidence. Earth system history is no exception. High-quality instrumental records spanning the past century exist for most parts of the world, but the records become sparse in the 19th century, and few records predate the ...

By 2007, the accumulation of new Earth science data helped the Intergovernmental Panel on Climate Change - the United Nations body established to assess the science related to climate change - reach the conclusion that "Most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed ...

I n so many ways, not much has changed since the United Nations Intergovernmental Panel on Climate Change (IPCC)—perhaps the premiere climate science-and-policy organization in the world ...

The evidence that humans are causing climate change, with drastic consequences for life on the planet, is overwhelming.. Experts began raising the alarm about global warming in 1979, a change now ...

In 2015, the Paris Agreement, which is legally binding on climate change, has been accepted by approximately 191 countries to limit global warming to below 2, if possible, to 1.5. The countries have committed to achieve this primary goal and minimise global warming. To accomplish this goal requires all parties to put forward their best efforts ...
