Rain and snow storms pounded Northern California in January 2017, bringing much-needed precipitation, but also causing damaging floods.
Recent heavy rains all over the U.S. have been attributed to a warming planet, according to the Environmental Protection Agency (EPA). Between 1910 to 2015, parts of the country seeing "extreme single-day precipitation events" increased by 0.5 percent per decade, the agency says.
Over the past 20 years, the average number of wildfires larger than 1,000 acres has increased by more than 100 blazes per year. Since the early 1970s, the average length of wildfire season has also gone up, from five months to seventh months, as climate change drives up temperatures.

The Maldives will be one of the first countries to be submerged by rising waters.
Human-induced global warming is causing glaciers and polar ice caps to melt leading to a rise in ocean levels. This October 2016 photo shows the construction of a bridge meant to ease commutes during unpredictable weather amid rising sea levels.
Drinking water is a constant problem in rural Sundarban, a region that spans the coastal delta of India and Bangladesh. A girl collects water pooled above parched terrain in this photo from the Dreamstime agency.
The riverbed of the Belesar reservoir is visible due to drought in northwestern Spain in January 2017.
While increased temperatures due to climate change have caused heavier rains in some areas, locations situated far from storm tracks are likely to experience less precipitation and faster evaporation due to the rising temperatures, according to the EPA.

Government scientists say the Earth sizzled to a third straight heat record last year. Globally, the average temperature over land and ocean surfaces for 2016 was the highest since record keeping began in 1880.

A puppy sits next to a walrus skull and a chain saw in Newtok, Alaska, July 3, 2015.
Newtok is one of several remote Alaskan villages that is being forced to relocate due to warming temperatures, which are causing the melting of permafrost, widening of rivers and the erosion of both land and coastline.
Over 23 million people across East Africa are facing a critical shortage of water and food, exacerbated by climate change. As a result, communities are being forced to settle near the remaining water sources, overburdening the scarce reserves.
Large quantities of seaweed wash ashore at the Playa Los Machos beach, in Ceiba, Puerto Rico, August 8, 2015.
This seaweed invasion, which appears to have hit most of the Caribbean this year, is not only bad for tourism; it may be a symptom of global climate change, as some scientists believe the onslaught of seaweed to be the result of higher than normal temperatures and low winds.
Walruses are unique among sea mammals in that they must periodically rest on land or ice to recharge. They prefer to do this on sea ice over shallow feeding areas about 100 miles off the Alaskan coast. Over the last decade, however, that ice has been disappearing, forcing thousands of walruses to haul out on Alaskan beaches.
This small detail crop of an aerial photo by Gary Braasch shows thousands of walruses engaged in one of the earliest known haul-outs ever.
It is said walruses are "hauling out" when they congregate in large groups, like the one seen here.
Recently, there have been years when more than 30,000 of these Pacific animals have come ashore together on Alaska's beaches, a dangerous trend that often leads to significant loss of life. This on-land crowding is particularly dangerous for baby walruses, who are uniquely susceptible to being crushed during stampedes.
Greenland is the world's largest island, and more than five-sixths of it (about 695,000 square miles) is covered in ice. That's an area roughly 14 times the size of England. So, if all of that ice were to melt -- and it is melting fast -- world sea levels would raise more than 19 feet.
Much of Nevada's Lake Mead has dried up as a result of the historic drought crisis along the West Coast of the United States. Here, tamarisk plants grow on cracked earth in an area that, up until recently, would have been underwater.
The National Park Service has been forced to close boat launch ramps and move entire marinas in an effort to keep up with the receding water levels. Lake Mead is the largest man-made reservoir in North America, and it is now threatened due to a combination of population growth and climate change.
A California resident holds a can of drinking water donated by the Anheuser-Busch company, as water wells supplying hundreds of Tulare County residents remain dry for the fourth year in a row, February 11, 2015.
A firefighter in Civitavecchia, Italy battles flames destroying a Mediterranean pine forest during a hot, dry Italian summer. In recent decades, these types of fires have been increasingly frequent in the region.
Beijing shrouded in air pollution on a winter morning. Breathing polluted air already to more than 5.5 million premature deaths a year, and researchers predict that by 2030, air pollution-related deaths could rise by 60,000 a year due to the effects of climate change. Higher temperatures and drier conditions "can speed up the reaction rate of air pollutants that form in the atmosphere," University of North Carolina-Chapel Hill researcher Jason West explained.
Cattle walk on a field in Texiguat, Honduras, July 26, 2015.
Honduras has been hit by a major drought linked to the El Nino climate phenomenon, a band of unusually warm Pacific ocean temperatures which have been known to spark floods, droughts and bush fires from South America to Australia.
The drought has already killed thousands of cattle and dried up much-needed crops.
Patterns reveal that Greenland's ice is rapidly being pressed away from the middle of the island; glaciers are sliding slowly between mountains before breaking off into icebergs that float out of the fjords.
This photo illustrates the gravity of the runoff from these glaciers.
Cracked earth is all that remains where water once stood at the Pejar Dam, one of Goulburn, Australia's primary water supply reservoirs.
An Australian federal government report has found that the Australian continent will likely warm between one and six degrees by 2070. Consequently, Australia could suffer more tropical storms and droughts, which cut farm output by billions of dollars. In addition, tourism could suffer from damage to reefs, rainforests and beaches.
A NASA study published in the Journal of Climate shows that the oldest and thickest Arctic sea ice is disappearing at a faster rate than the younger, thinner ice at the edges of the Arctic Ocean's floating ice cap. Images show the ice cap in 1980, left, and in 2012, right.
In April 2017, more than 400 icebergs drifted into North Atlantic shipping lanes. Experts attributed it to uncommonly strong counter-clockwise winds drawing the icebergs south, and perhaps also global warming accelerating the process by which chunks of the Greenland ice sheet break off and float away.
