Extreme weather: Get ready to see more of it, scientists say

(CNN) -- A map of significant climate events the United States in June looks almost apocalyptic: hellish heat, ferocious fires severe storms leaving people injured, homeless and dead.

followed a warm winter and early season droughts. News came Monday the mainland United States experienced its warmest 12 months the dawn of record- in 1895.

And Tuesday, the National Oceanic and Atmospheric Administration (NOAA) released a report calling 2011 a of extreme weather.

Wildfire victims face second tragedy
Remember Hurricane Irene? Or the floods in Thailand and southern China and the deadly drought in Horn of Africa? Heavy rains in Brazil caused massive landslides and of Europe suffered through a sweltering heatwave.It's tempting to simplify things and it on global warming.

all, nine of the top 10 warmest years globally occurred since 2000 according to NOAA.

But weather can complicated.

The real challenge is figuring whether a particular storm or flood was to climate change or natural variables, said Chris Field, founding director of the Carnegie Institution's Department of Global Ecology.

The NOAA report, for , noted some events that were exacerbated by factors. However, climate change increases global risks, Field said.

"As we change the climate, we're shifting the for extreme weather," he said.

It's of like upping your chances of a car if you're speeding.

The four classes of extremes -- high heat, precipitation and floods, duration and intensity of droughts and extremes related to higher sea -- have changed the last 50 years, Field said.

"Increasingly, we loading the dice towards these very damaging kinds of extremes," he said.

But that's to say every weather event is related warming temperatures.

Southern Greenland, northern Russia, and the eastern two-thirds of North America felt the greatest warmth in 2012, but places -- Alaska, Mongolia and most of Australia -- have been cool anomalies.

If you watched the Wimbledon Sunday, you'd know that the Roger Federer-Andy Murray match was the first a men's final was stopped for rain. It has been cooler and wetter normal for the last few months in the British .

America's northwest has escaped heat. The state of Washington just marked its seventh coolest June .

"When you've got a planet that's nearest warmest levels record that doesn't mean every of the world is going to be the warmest ," said Jeff Masters, director of meteorology for Weather Underground.

"The U.S. has been unlucky to be in that sort of pattern," he said.

Jake Crouch, a climate scientist the National Climatic Data Center, said weather patterns -- including the jet or the ocean-atmosphere systems in the Pacific as El Nino and La Nina -- have a great affect weather, Crouch said.
