Changing weather patterns caused by increasing global temperatures means meteorologists can no longer rely on historical rainfall records to predict future weather events. Instead, a new supercomputer at the Met Office simulated thousands of possible scenarios using current climate patterns.
As the ice-free areas expand, the distances between them will decrease, giving plants and animals more opportunity to spread through the landscape. On the Antarctic Peninsula, which has already warmed more than anywhere else in Antarctica, many of the ice-free patches will expand so much that they will start joining together.
Will this increase in habitat availability benefit the plants and animals that live there? It will definitely provide new opportunities for some native plants and animals to expand their range and colonise new areas. The warming climate may also give a boost to species that are currently hampered by the lack of warmth, nutrients and water.
However, the potential benefits seem likely to be outweighed by the negatives. The joining-up of habitat patches could allow species that have been isolated for much of their evolutionary past to meet suddenly. If the newcomers to a particular area outcompete the native species, then it may lead to localised extinctions. Over the coming centuries this could lead to the loss of many plants and animals, and the homogenisation of Antarctica’s ecosystems.
In the waterlogged Netherlands, climate change is considered neither a hypothetical nor a drag on the economy. Instead, it’s an opportunity.
Less than three weeks after President Donald Trump pulled the United States from the 195-nation Paris Agreement on climate change, there’s a new ragtag group of underdogs supporting carbon-cutting.
Lawmakers from nations in the North Atlantic Treaty Organization are warning that global warming will lead to mass migration and conflict in the Middle East and Africa, another reason President Donald Trump should stay in the Paris climate deal.
Coffee crops are under siege from deforestation, abnormally high temperatures, a lack of precipitation, and disease. The global market is heading for its fourth straight year of deficit, according to estimates from Rabobank International. At the same time, global demand for the beloved beverage is expected to reach an all-time high this year, led by demand from younger American consumers. Production will need to increase at least 50 percent by the middle of this century to keep pace with the demand, says Conservation International, an environmental organization. To cope, the industry is rushing to develop plants that can adapt with the changing environment.
With a record number of Americans sounding the alarm on global warming, the share of the U.S. population that Gallup categorizes as “Concerned Believers” on climate change has consequently reached a new high of 50%. This is up slightly from 47% in 2016 but is well above the 37% recorded only two years ago.
Record percentages of Americans are concerned about global warming, believe it is occurring, consider it a serious threat and say it is caused by human activity. All of these perceptions are up significantly from 2015.
Study shows 52,000 square miles in rapid decline, with sediment and carbon threatening the surrounding environment and potentially accelerating global warming.
