Views about the existence and causes of global warming have changed little over the past year. A new Pew Research Center poll finds that 59% of adults say there is solid evidence that the earth’s average temperature has been getting warmer over the past few decades. In October 2009, 57% said this.

It's time to listen – and take action. There's plenty we can do

Animals become affected by global warming due to changes in their habitats caused by changes in climate.

The changes in temperature caused by global warming will have a number of effects on the habitats of animals. The melting ice will cause the loss of habitat for species such as the polar bear. Warmer water will also cause the population of fish such as trout and salmon to decline.

Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate. There is great debate among many people, and sometimes in the news, on whether global warming is real (some call it a hoax). But climate scientists looking at the data and facts agree the planet is warming. While many view the effects of global warming to be more substantial and more rapidly occurring than others do, the scientific consensus on climatic changes related to global warming is that the average temperature of the Earth has risen between 0.4 and 0.8 °C over the past 100 years. The increased volumes of carbon dioxide and other greenhouse gases released by the burning of fossil fuels, land clearing, agriculture, and other human activities, are believed to be the primary sources of the global warming that has occurred over the past 50 years. Scientists from the Intergovernmental Panel on Climate carrying out global warming research have recently predicted that average global temperatures could increase between 1.4 and 5.8 °C by the year 2100. Changes resulting from global warming may include rising sea levels due to the melting of the polar ice caps, as well as an increase in occurrence and severity of storms and other severe weather events.

Global warming is a problem which each of us contributes to because our everyday activities require the burning of fossil fuels which result in carbon dioxide (CO2) emissions, one of the major greenhouse gases that causes global warming.

When it comes to connecting the dots between climate change, extreme weather and health, the lines are clear. The earth is saying something with record heat, drought, storms and fire. Scientists are telling us this is what global warming looks like

Climate change will have a significant impact on the sustainability of water supplies in the coming decades. A new analysis, performed by consulting firm Tetra Tech for the Natural Resources Defense Council (NRDC), examined the effects of global warming on water supply and demand in the contiguous United States. The study found that more than 1,100 counties -- one-third of all counties in the lower 48 -- will face higher risks of water shortages by mid-century as the result of global warming. More than 400 of these counties will face extremely high risks of water shortages. Read more »

Each year American power plants pump more than two billion tons of carbon dioxide into the air. EPA's new standards would reduce carbon pollution and protect public health. Read more »

The Earth’s population is set to increase to 9 billion by 2050. If we continue to act as we do today, by this time the demand for resources will be three times greater than the planet can supply. This means: change needs to happen.   Consumers and retailers are increasingly looking for more sustainable products. This means efficiency and sustainability are key – as we need to produce more with less. To remain competitive, brand owners and manufacturers must keep pace.

Electricity production generates the largest share of greenhouse gas emissions.

Greenhouse gas emissions from transportation primarily come from burning fossil fuel for our cars, trucks, ships, trains, and planes.

The current cycle of global warming is changing the rhythms of climate that all living things have come to rely upon. What will we do to slow this warming? How will we cope with the changes we've already set into motion? While we struggle to figure it all out, the face of the Earth as we know it—coasts, forests, farms, and snowcapped mountains—hangs in the balance.

Humans are incresing polution which is harming our planet by making global warming more usual

There is strong evidence that the warming of the Earth over the last half-century has been caused largely by human activity, such as the burning of fossil fuels and changes in land use, including agriculture and deforestation.
