Which is possible outcome of global warming




















It is projected to rise another 1 to 8 feet by This is the result of added water from melting land ice and the expansion of seawater as it warms.

In the next several decades, storm surges and high tides could combine with sea level rise and land subsidence to further increase flooding in many regions.

Ocean waters will therefore continue to warm and sea level will continue to rise for many centuries at rates equal to or higher than those of the current century. An indicator of changes in the Arctic sea ice minimum over time. Arctic sea ice extent both affects and is affected by global climate change. An interactive exploration of how global warming is affecting sea ice, glaciers and continental ice sheets worldwide. Below are some of the impacts that are currently visible throughout the U.

Global Change Research Program :. Heat waves, heavy downpours and sea level rise pose growing challenges to many aspects of life in the Northeast. Infrastructure, agriculture, fisheries and ecosystems will be increasingly compromised.

Many states and cities are beginning to incorporate climate change into their planning. Changes in the timing of streamflow reduce water supplies for competing demands. Sea level rise, erosion, inundation, risks to infrastructure and increasing ocean acidity pose major threats. Increasing wildfire, insect outbreaks and tree diseases are causing widespread tree die-off. Extreme heat will affect health, energy, agriculture and more. Decreased water availability will have economic and environmental impacts.

Extreme heat, heavy downpours and flooding will affect infrastructure, health, agriculture, forestry, transportation, air and water quality, and more. Climate change will also exacerbate a range of risks to the Great Lakes. An iceberg melts in the waters off Antarctica. Climate change has accelerated the rate of ice loss across the continent. But planting trees, restoring seagrasses, and boosting the use of agricultural cover crops could help clean up significant amounts of carbon dioxide.

Restoring forests already chopped down in Brazil, for example, could draw about 1. Those are relatively modest numbers given historic carbon emissions of 2. Communities around the world are already recognizing that adaptation must also be part of the response to climate change.

From flood-prone coastal towns to regions facing increased droughts and fires, a new wave of initiatives focuses on boosting resilience. Those include managing or preventing land erosion, building microgrids and other energy systems built to withstand disruptions, and designing buildings with rising sea levels in mind. Recent books such as Drawdown and Designing Climate Solutions have proposed bold and comprehensive yet simple plans for reversing our current course.

The ideas vary, but the message is consistent: We already have many of the tools needed to address climate change. Some of the concepts are broad ones that governments and businesses must implement, but many other ideas involve changes that anyone can make— eating less meat , for example, or rethinking your modes of transport.

That, of course, is the bad news. But there's also good news. By aggressively reducing our global emissions now, "we can avoid a lot of the severe consequences that climate change would otherwise bring," says Haq.

From dusty fields in the San Joaquin Valley, fungal spores are wafting up, exposing more and more farmworkers to the disease. The western city of Ahmedabad is preparing residents to cope with the longer and more intense heat waves sweeping across South Asia—and inspiring other Indian cities and states to follow suit.

By embracing green infrastructure, these urban areas have a solid defense against increased drought or flood. Sea life of all kinds relies on this feeding and mating frenzy, but the setting for grouper romance has to be just right. Healing the planet starts at home—in your garage, in your kitchen, and at your dining-room table.

According to this, extensive ice surfaces have a cooling effect on the global climate, as a high proportion of radiation is reflected. As a result of the global rise in the average temperature, however, these ice surfaces begin to melt, the ice surfaces shrink and the amount of reflected radiation is reduced.

At the same time, the area of land or ocean that has a significantly lower albedo will increase, reflecting less radiation and thus intensifying the actual cause of glacier melt.

Furthermore, scientists can calculate the so-called tipping points of individual subsystems of the global climate. The higher the global rise in temperature, the more the climate system is affected, so that at a certain point, despite significant efforts, a reversal in the process is no longer possible.
